Power in Protein

I purposely saved protein as the last macronutrient to discuss.  People don't seem to have the same fear of protein as they do with fats or carbohydrates, and it is thought that in general, most Americans get plenty of protein.  My question to you is: are you selecting the appropriate sources?


While carbohydrate and fat are the main sources of fuel during a bout of exercise, protein still has many essential purposes.  It provides the building blocks for bones and muscles, creates enzymes responsible for producing energy and repairing muscle after exercise, and creates the transport systems for nutrients and oxygen within the body.


How much should I eat?
Just as we discussed with Carbohydrates, your protein consumption should be related to your body weight and activity level.  The current "recommended daily allowance" for protein for adults is 0.8 g/kg of body weight.  This equates to approximately 10-35% of one's caloric consumption.  However, in the research lab I work in, we encourage participants to eat 45% of their calories from protein.  This helps to build and maintain more muscle mass when combined with a resistance training program (additionally it has been proven more successful than higher carbohydrate amounts in our weight loss programs).  A more fitness-friendly suggestion is to consume one of the following:
- For more endurance based individuals: 1.2-1.4 g/kg of your body weight
- For those who focus on resistance training: 1.6-1.7 g/kg of your body weight


Here is my example: On average, I work out 1 hour a day, 5 days a week.  I perform moderate intensity resistance training and cardio.  I would probably start with 1.2-1.3 g/kg of protein in my daily diet, and then increase my protein intake if I didn't feel like I was consuming enough calories in a day (for instance, if I was losing weight when my goal was to increase muscle size). 


A review of the calculation:
1. Take your weight in pounds and divide by 2.2 to get your weight in kilograms.
2.  Select your level of physical activity and the corresponding grams of protein you would like to start with.
3.  Multiply your weight in kg times the number of g/kg of protein for your activity level.  I suggest starting with the low to mid number in the range.
I suspect most of my readers will be in the 1.0-1.5 g/kg range.   

Here is my personal example:

125 lb / 2.2 = 57 kg

57 kg * 1.2 g/kg = 68.4 grams of carbohydrates/day

Now, if you do the math between my carbohydrates, protein, and fat examples - you'll realize that based on this calculation, I am still eating way less protein than carbohydrates, AND protein is definitely not 45% of my caloric intake.  But you will also see that it only adds up to about 1570 calories total.  This is where I would start adding more healthy protein (not carbohydrate or fat) to my diet to continue to increase the caloric intake to a comfortable level for me.


What kind should I eat?
You probably remember from early science classes that "amino acids are the building blocks of protein."  There are 20 amino acids (AAs), and our body can produce about half of them itself.  These are called nonessential AAs, because it is "not essential" that we obtain them from our diet.  The remaining AAs are "essential" for us to obtain in our diet because our body cannot produce them.  So when we discuss types of protein, we talk about complete sources that contain all of the essential AAs (typically animal proteins such as meat and dairy products), and incomplete sources that may be missing out on a few of those essential AAs (vegetable proteins such as grains, legumes, nuts and seeds).  A common suggestion is to pair two incomplete proteins within a meal (or throughout the day) to make sure you obtain all of the essential AAs.  Some examples include soybeans + rice, wheat bread + peanut butter, pinto beans + corn tortillas. 


Here is a chart from my textbook that shows you the amount of protein you can find in common foods (click on the chart and a larger version will open in a separate window):

In addition to making sure you are obtaining all of the essential amino acids, it is also important to opt for protein sources that are healthier for you - such as being lower in fat.  Here are a few pointers to keep in mind:
- Look for lean cuts of meat.  "Prime" and "Choice" are going to be good options.
- Prepare the meat in a way that limits added fat.  Opt for the grill where fat can drip off, instead of frying.
- Try to limit your consumption of red meat as well as deli meats (excess consumption can lead to colon cancer).  Buy deli meats that are non-cured and nitrate-free.


When should I eat them?
It is best to combine protein and carbohydrates during every meal and snack.  This will keep you feeling full longer and gives your body the nutrients it needs throughout the day as you go from task to task.  
Here are a few exercise-specific tips:
- Consume carbohydrate and protein in a 3:1 ratio after an exercise session to stimulate recovery of glycogen stores and maximize muscle synthesis.
- The aforementioned may also help to decrease muscle soreness.
- It may be best to consume smaller portions every 1-2 hours post-exercise to sustain the elevated synthesis rates.


And to end, here is an interesting tidbit for vegetarians:
This is news to me, so I am going to quote it straight out of my trusty textbook:  "Proteins derived from plant foods are approximately 85% digestible, those in a mixed diet of meat products and refined grains are approximately 95% digestible.  Based on these differences, it is recommended that people who eat no flesh or dairy products consume 10% more protein daily"

Fearful of Fats

We should all just avoid fats because eating fat will make us fat... right?  Well, not necessarily.  As we've discussed before, making sure we don't eat too many calories (and also burning excess calories through physical activity) is going to be key in not gaining fat... and for the record - eating too many carbohydrates or protein can also lead to fat gain.  So let's be a little more gentle with our fear and hatred of fats (of course we all love the taste!) and obtain a better understanding of why they NEED to be part of our diet, and which types are beneficial and which to avoid.

I didn't mention this last week when we discussed carbs, but fat and carbohydrate are actually the two types of fuel your body uses during exercise.  When you perform more sustained, endurance-type exercise, you will utilize more fat as your fuel source.  And believe it or not, fat is our primary source of fuel at rest as well (no need to feel guilty sitting around reading my blog... you are burning fat right now!  ).  There are also certain nutrients that we obtain from the fats in our diet: Vitamins A, D, E and K, as well as the essential fatty acids linoleic and alpha-linolenic acid (Omega-6 and -3 respectively).  These nutrients are needed for many metabolic processes and also to make various compounds within the body.  They make up the cell membranes, parts of the brain and spinal cord, keep skin and tissues pliable, protect the organs, and store energy.  All sorts of good and necessary things!

How much should I eat?
The major concern with fats is that they are more calorie dense than protein and carbs.  Both carbs and protein contain approximately 4 calories per gram.  Fat, on the other hand, packs 9 calories per gram!!  That means if you ate the same size morsel of fat as carbohydrate, the fat morsel would contain more than twice as many calories!
The general recommendation is for 20-35% of your caloric consumption to come from fat.  It is rare to come across a suggestion based on your body weight like we discuss for both carbohydrates and protein.  I would advise calculating your carbohydrate (see last week) and protein (see next week) based on your body weight and activity level, then divide that number by 0.75 to get an idea of your total caloric intake.  The 0.75 is accounting for 25% of your diet coming from fats.  Here is an example:
- If I calculated my carbohydrate and protein intake to be 1,500 calories a day,
- I would then calculate 1,500 / 0.75 = 2,000
- This means that I should start out by eating 2,000 calories a day, with 500 calories/day as my fat allotment.
- Notice I said "start out by eating..." unless you get your metabolism tested, this will be a bit of a guessing game getting you to the appropriate caloric intake.

What kind should I eat?
Once you have figured out your fat caloric allotment, I'm sorry to tell you, it is not a free for all.  Now we need to focus on the specific types of fat you should consume in your diet.  Words to look for on a food label:
GOOD FATS - Pick these!!  
- monounsaturated 
- polyunsaturated
Both of these can actually improve your cholesterol levels, potentially assist in regulating insulin levels, and decrease your risk of heart disease.  They are heart healthy!
BAD FATS - Try to avoid these!!
- saturated: comes primarily from animal products.  This should be less than 1/3 of your fat calories for the day... meaning if you are allotted 500 fat calories, less than 165 calories should be saturated fat (that's only 18.5 grams of fat!)
- trans: these fats have been processed to increase the shelf life.  They typically have negative effects on blood cholesterol levels.  Avoid these as much as possible.
- hydrogenated: Foods may say "trans-fat-free," but if you look at the list of ingredients and either "hydrogenated" or "partially hydrogenated" is listed, then there is some level of trans fat in that food.  Most likely < 0.5g per serving... but if you indulge in more than one serving, that number adds up!

What are good sources?
As I just learned in my textbook*; animal fats provide ~40-60% of their energy as saturated fats and 30-50% as unsaturated, whereas plants provide only 10-20% of their energy from saturated and the rest from unsaturated.  I am not saying that you should not eat meat - but certainly aim for leaner cuts of meat and discard all visible fat.  Additionally, try too cook it in a way that the fat will drip off (grilling) as opposed to  continue marinating around the meat (pan frying or baking).

Another good rule of thumb in selecting your fats: unsaturated fats are typically more liquid at room temperature (oils = unsaturated, butter and Crisco = saturated).  And since we are always hearing about getting in our Omega's, here is where you can get them:
Omega 6: vegetable oils (sunflower, safflower, corn, soy, peanut)
Omega 3: leafy green vegetables, soy products (including oil), seafood, canola oil

Finally, I will leave you with a list of good sources of healthy, obtained from another great resource**.  Try to obtain your "fat fuel" from these:
Foods low in saturated fat: popcorn, nonfat yogurt, skim milk, fig bars, graham crackers, roasted chicken breast, pancakes, 1% cottage cheese, 1% chocolate milk, dried beef
Foods high in monounsaturated fat: black olives, olive oil, almond oil, canola oil, dry almonds, avocados, peanut oil, dry roasted cashes, peanut butter, cooked beef, roasted lamb, roasted veal
Foods high in polyunsaturated fat: safflower oil, sunflower oil, corn oil, dry walnuts, sunflower seeds, margarine, corn oil, canola oil, sesame seeds, pumpkin seeds, tofu

Caution with Carbs

Carbohydrates... friend or foe?  I imagine many of us have a love-hate relationship with them.  But what exactly comes to mind when you think of eating carbs?  Are you thinking pancakes, heaping plates of pasta, and pastries... or are you thinking fruits, vegetables and whole grains?  This could be the determining factor of your relationship with carbs and your success (or struggles) with weight management.

How much should I eat?
We've previously discussed that it can be kind of difficult to know how many calories you should be eating a day - without having specific metabolic testing done.  In addition, you may have heard me suggest that the recommended daily amount of carbohydrates should be 50-55% of your total caloric intake.  But if you don't know how many calories you should consume, then this percentage isn't very helpful.  Likewise, the truth is that the amount of carbohydrates you should consume is going to vary depending on your body size, health status, and also your level and type of physical activity (duration, intensity, frequency, etc).
Taking this information into consideration, let's calculate the following:
1. Take your weight in pounds and divide by 2.2 to get your weight in kilograms.
2.  Select your level of physical activity:
*recreationally active (exercise 30-60 minutes most days of the week / not training for an event): 3-5 g/kg.
*moderately active, but low endurance (such as football players, and other sports that do not require continuous activity for long periods of time without breaks): 5-7 g/kg.
*highly active, high endurance (training for a long distance event, frequently training for 2+ hours a day): 7-10 g/kg.
3.  Multiply your weight in kg times the number of g/kg of carbs for your activity level.  I suggest starting with the low to mid number in the range.
I imagine most of my readers will be in the 3-5 g/kg range.  I personally aim for 4 g/kg.

Here is my personal example:

125 lb / 2.2 = 57 kg

57 kg * 4 g/kg = 225 grams of carbohydrates/day

I have actually met with a nutritionist and was given this recommendation.  But it doesn't stop there.  We still need to look at the type and timing of the carbohydrates.

What kind should I eat?

We have all heard of simple and complex carbohydrates.  I have always used their name as an explanation for how your body breaks them down (simple are more easily digested, give you a quick sugar spike, and then leave you hungry/tired... complex take longer to digest, keep you full longer, and give you a steady level of energy).  But I have recently learned that this is not correct!  The name is merely describing the structure of each carb.  Complex carbs have a more "complex" chemical structure and tend to be less processed and higher in nutrients and fiber than simple carbohydrates.  So in the end, it is still a better idea to pick complex carbs such as fruits, vegetables, whole grains (bread, cereal, pasta) and legumes (beans, peas, lentils) over simple carbs such as sweetened cereals, breakfast bars, candy, soda and dessert.

There is another way we can categorize our carbs: by the glycemic index.  This categorizes foods as having a high glycemic response (quick rise in blood sugar and insulin), moderate, or low glycemic response (slow rise in blood sugar and insulin).  It is better to consume more foods that are low-moderate glycemic index in order to keep from having insulin spikes that could potentially lead to issues with insulin resistance.  Here is a GI index list of some common foods:

Additionally, CLICK HERE for a website where you can search any food item you would like, to see the glycemic index and also the grams of carbs per serving (click the tab on the left for GI database).   

Of course it can't really be this clear cut and easy.  As you start to mix carbohydrates together, or add protein and fat to the meal, that can alter the glycemic index of a food.  But this at least gives you a good idea of which foods to make "all the time foods" and which foods should only be "sometimes foods" (as explained to me by my darling niece and nephew).  And as we'll discuss below, there are certain times you might want to focus on lower GI foods and other times that high GI foods are beneficial.

When should I eat them?

It is a good idea to spread your nutrients out throughout the day.  Keep in mind that the main purpose of eating is to fuel your body.  If you consume too much at once, it may go to fat for storage.  If you don't consume enough - you may run out of energy.

As a general rule, try to consume about 20% of your carbohydrate grams at every meal, and 10-15% during three snacks spread throughout the day.  

For example, the suggestion I received for myself from the nutritionist was as follows:

Consume 225 g/kg of carbs per day

Aim for 45 g for each meal

Aim for 30 g for each snack

(3 meals + 3 snacks = 225 g)

This is a good way to ensure that your blood glucose and insulin will stay more stable throughout the day.

However we should also consider your carbohydrate intake in regards to your activity level.  Here are a few pointers:

* It is good to eat a pre-exercise meal or snack 1-3 hours before your exercise session to make sure you have energy.  Since we want to sustain energy, aim for low-moderate glycemic index foods here.

* If your exercise session lasts an hour or less, you don't need to be concerned with consuming carbohydrates during your workout.

* If your exercise session lasts well over an hour, you may want to consider some carbohydrate supplementation along the way - through sports drinks, sports beans, gel packs, etc.  This will help maintain your endurance for a longer duration.

* Since glucose is the primary source of fuel used during exercise, it is good to replenish after an exercise bout.  In fact, if you had a strenuous endurance session, it is very important that you aim to replenish your carbohydrates within 30 min - 2 hours after your exercise session, otherwise you may not actually be able to refill your glycogen stores as fully.  Since we are aiming for quick absorption here - high glycemic index foods are actually best.  Interestingly, fructose is digested slowest of all of the sugars, so it may not be best to use fruit or fruit juices for replenishment purposes.

This certainly is not an exact science.  It will be different for each individual, and your guidelines may need to be a little different each day - depending on your level of activity.  Use this information (and the information to follow on protein and fat in the weeks to come) as a guideline, and feel free to adjust your numbers up or down a little to meet your needs.

I'll end with a few more tidbits that I picked up from my meeting with the nutritionist:

1. Everyone should consume at least 1/2 cup of either nuts or beans every single day.

2. Better cereal choices include whole grain varieties like Total or Wheaties, and you can mix in your own fresh fruit.

3. From a sugar standpoint, she perfers "no sugar added" ice cream over frozen yogurt.  

We didn't discuss simple sugar too much in this post... and that is because those are not the types of carbohydrates we are aiming for.  When you are reading a nutrition label, look at how many grams of carbs are in a serving, and then look below to see the sugar content.  Try to aim for food choices that don't have all of their carbs coming from simple sugars.  If you stick with the whole grain variety, you'll be doing much better.  Save your simple sugars for the natural sugars in fruits and veggies.  And remember: items like pasta and rice should be a SIDE DISH, not your main entree.  A serving should be no larger than the size of your computer mouse (so cute and tiny, right?!).

I hope this will make you a little less fearful of carbohydrates, and help you gain confidence and responsibility in your food selection.  As mentioned, stay tuned for similar information on protein and fats!

Have a HEALTHY day!

Healthy Alternatives

I feel like I am kind of cheating with my post today - because I am just posting something that I found in a textbook. This is actually from my professor's textbook which I have spent the month of June editing and creating multiple choice questions for, to be used for a certification exam. In fact it is due tomorrow, which is why I haven't had much time to post anything else this week!

For the month of July, Fit Britt will be focusing on the three main macronutrients: Carbohydrate, Protein, and Fat (one each week). We will review details of the good and the bad varieties, why you need them, what quantities you should consume, what happens if you consume too much of that specific nutrient, etc. The last week in July we will be prepared for a "Food for Fuel Challenge." Using all of the information we collect throughout the month, we'll see if we can go a full week eating only the foods that our body thrives on for energy and metabolic processes.

So... let this be a little "appetizer." This is a pretty interesting chart to see how many calories are in certain foods, and in the right column you can get an idea of how much healthy / nutrient-dense food you could eat to fulfill the same number of calories. Pretty impressive!

Shaking Things Up

The lab I work in, the Exercise and Sport Nutrition lab, does a lot of research dealing with exercise and supplementation for weight loss, health improvements, and also athletic performance. For the majority of our studies, we encourage our participants to consume a high protein diet rather than a high carbohydrate diet. Not Atkins-style, just 45% calories from Protein, 30% from Carbohydrates and 25% from Fat. I try to follow this diet myself, and it doesn't take long before I become bored chicken breasts and beans. You soon realize, on a higher protein diet, that it is convenient to get some of your protein source from supplements and shakes.

While there are higher protein (and not as tasty) shakes out there that you might be more interested in if you are doing heavy weight lifting and muscle building, I have found a shake mix that I ABSOLUTELY look forward to having every day. It is called Vi-Shape by Visalus Sciences. (You can click the link to see the nutritional information). Not only does it have a decent amount of protein (especially if you mix it with milk) but it also contains a lot of vitamins and minerals. You may have heard of the Body by Vi challenge, where you use a shake as a meal replacement each day as part of a weight loss protocol. I personally like to use the same shakes as an afternoon snack, or after a workout. They are great whatever your goals are!

There is only one flavor of the mix, Sweet Cream, and it tastes like cake batter! Plus, there are tons of great recipes out there so you never have to drink the same shake twice! I like mixing in frozen fruit and/or sugar free chocolate pudding mix, yum! I always use skim milk to add more protein, but you could use water or soy milk. Check out a large list of possible recipes!
AND I treated myself to my new favorite item: The Magic Bullet. I bought it at Bed, Bath & Beyond for $40 (they were selling it for $10 off) PLUS a $10 mail-in rebate. Not a bad deal in the end. So far I have only used it for my Vi Shakes, but there are lots of great recipes for making salsas, guacamole, anything you want to blend or puree, and even frozen beverages!

I am not a consultant for Visalus, nor do I intend to become one. I purchase my shake mix through a friend (and got a discount for signing up for an auto-monthly ship that I can cancel at any time, even after one shipment). On the autoship it is $49 for a month supply. If you are local and want a taste I'd be happy to whip one up for you or give you a little bag of powder! If you think you might want to try it out, you can order your own bag here (and click "Join the Challenge)! If I refer 3 people, I get a month supply free... and you can too if you do the same!

A Fit Bit of Inspiration

At the end of every yoga class, as we are finishing our meditation, I read a quote. I found a great little quote book called "The Daily Book of Positive Quotations" by Linda Picone. I get a lot of positive feedback about many of the quotes in this book, but the one I read last night really spoke to me and a couple of my fellow yogis. It is very applicable to what we discussed last week regarding accountability (in training, work projects, whatever), so I wanted to share it with you:

"You can't wait for inspiration. You have to go after it with a club" ~Jack London

Author's comments: Some artists wait to be struck, like lightening, by inspiration and then follow the inspiration wherever it leads. Others simply get up everyday and go to work. They write until they've produced a certain number of words. They draw until they've completed a certain number of sketches. These artists don't wait for inspiration, they work. And work. And work. And eventually, inspiration makes an appearance.

Self Reflection: I sometimes use lack of inspiration as an excuse for not doing things I say I love. Today I'm going to go ahead and do what I love and not wait to be inspired. If I have to, I'll make my own inspiration.

This really spoke to me regarding my personal fitness, my blogging, and especially my school projects. I hope it speaks to you as well... perhaps even inspires you!

Have a HEALTHY day!

Who or What is Holding You Accountable?

Some of the concepts I find myself discussing the most, whether it be related to fitness goals, weight loss, school projects, office projects, time management, whatever... are setting priorities and accountability. I completely understand how motivation comes in waves, and some days we are all a little more passionate about achieving our goals than others. I think I am a perfect example of this by the fact that I took a good 6 months off of blogging. It isn't that I didn't want to blog anymore, but I let other priorities get in my way. I have stated to all of you (however many of you that are out there reading my babble) that my goal is to post once a week throughout the summer, and I certainly hope you will help to hold me accountable!

I hope that I can help you to achieve your fitness/health goals. Whether by being an encourager, sharing tidbits of information, answering your questions specifically, putting you in touch with other professionals, etc. But it certainly takes a team of supporters to obtain the best results.
Who or what is holding you accountable? Here are a few ideas you might find helpful. Please feel free to comment if you have additional suggestions!

1. Write down your goals on paper, and make sure they are SMART (see previous post)

2. Tell at least 3 people you trust (friends, family, spouse) your goals. If you are willing, give them a written copy of your goals. Be specific in asking them for help. Let me tell you, my husband [love you GymJim!] tells me all the time he wants to start doing certain exercise programs - but I have learned that he does NOT mean he wants me to remind him about them! :)
If you are actually looking for help/support, be clear about that!

3. Keep a food diary. All fitness/health results will be affected by your nutrition. As much as I advocate exercise - I'll be honest, that is a very small component of your results compared to what you are stuffing in your body 16-24 hours a day. And of course, each goal will have different nutrition needs. I do not recommend to anyone to keep a food diary every day - that is too tedious. I log my food at least one day a week to check in and see if I am eating the right amount of calories, and also if it is broken down into the proper percentages of protein, carbohydrates, and fat. There are a lot of websites that offer free and/or inexpensive food logging. I am a member of a site called DotFit (through HFPN) that I think is really great, because it uses the database from CalorieKing and you can also add in your own food items, etc. (You also start by doing a questionnaire related to your goals, and it gives nutritional recommendations based on your goal). I can give you a 14 day trial for free, and this does not include taking any credit card information from you or anything. Just comment below or email fitbritt@gmail.com if you are interested.

4. Wear a pedometer. This is a very affordable way to get an idea of whether or not you are getting an appropriate amount of activity each day. You can get pedometers for around $5 or less (of course the more you spend, the better the quality will be, plus a few additional bells and whistles). All you do is clip it to your waist band like a pager, and let it count your steps throughout the day. I would encourage you to wear it for a few days without trying to change your activity, recording your number of steps at the end of each day. Then, gradually try to work up to 10,000 steps/day. Someone set that as the magic number for health... it equates to ~5 miles of movement a day, and can be pretty challenging to reach if you have a desk job! But definitely a good number to aim for.

5. Use a heart rate monitor. Now I will go back to proclaiming how important your exercise is. It might only be 30 minutes to an hour of your day, but you better get the most bang for your buck (or calorie burn for your time)! A good heart rate monitor will have a chest strap that you wear against your bare skin, and also a watch (or waist clip) that gives you a readout of your heart rate. I personally like Polar monitors, they are a very well known brand that can be purchased in sports stores as well as online. I think I'll save the details for where your heart rate should be during your workout for another blog post... I've got to keep you coming back for more (and this post is going to get long)!

6. Wear an ExerSpy! or a BodyBugg, or a GoWearFit, or any of the other brands by BodyMedia - they seem to be the same! (But I happen to own an ExerSpy that you can use if you are local... and I also happen to sell them). If you do not know what this is, you are missing one of my favorite posts and favorite items of all times. In addition to logging your food intake, this arm band tracks your calories burned, steps taken, intensity level, and sleep efficiency around the clock. A friend of mine just got one, and she mentioned that one of the things she likes about it the most is she knows how many calories to eat each day based on her activity level (which of course, may change from day to day).

7. Share your goals on FitBritt.com. I created a new page, linked at the top of this blog titled "Hold Me Accountable!" for you to post your goals on this site!

It. Is. Get-ting. So. Hot.

Regardless of whether you live in TX and have been experiencing summer for a few months, or summer is just now finding its way to you, It's Getting Hot Out There!

Now that you are unable to hide your layers of 'natural insulation' underneath baggy clothes, you may be motivated to kick it into high gear and get bikini ready! Whatever your motivation, Fit Britt supports your workout endeavors! Here are a few tips to keep in mind when exercising in hot weather:

Heat Illness - The main concern is an increased risk of heat injuries (heat cramps, heat exhaustion, heat stroke). The first symptoms are headache and nausea, followed by muscle cramps and eventually lack of sweating, dry skin, etc. This can be avoided by making smart choices about your activities, attire, time of day, etc.

Reduced Performance - Additionally, depending on your level of competitiveness, you may be interested in learning that your endurance capacity and VO2max (efficiency of using oxygen during exercise) both decrease as you lose body weight from sweat and dehydration. These symptoms can be prolonged, if not avoided by making smart decisions and planning ahead.

Acclimatization - it is encouraging to note that you CAN acclimatize to the weather, to some degree (pun not intended). Whether you are just starting a new program and it happens to be the middle of summer, or you are competing in events that require you to travel to different climates, allow yourself 7-14 days for your body to become most efficient at working in the hot environment. You should notice that you actually begin to sweat MORE and lose less salt along the way.
Hydration - being dehydrated will decrease your body's ability to sweat as well as cool itself. Additionally, as you sweat, you decrease your blood volume by pulling water out of your body. This, in turn, makes it more difficult for your blood to circulate, deliver essential nutrients and remove waste as you continue your workout (hence the decrease in performance mentioned above).

In order to stay properly hydrated:

• Focus on staying well hydrated within the 24 hours before your exercise session (limit caffeine, consume foods that contain a lot of water such as fruits and carbohydrates).
• Drink 1-2 cups of fluid (preferably water or sports drinks) 1-2 hours before exercise.
• Typically, water is sufficient during activity for exercise sessions less than 60 minutes.
• When exercising for more than 60 minutes, and/or you are sweating a lot, incorporate a sports drink with carbohydrates (sugar = fuel!) and electrolytes (to replace the sodium you depleted while sweating). A good rule of thumb is to find a drink that has 6-8 grams of carbohydrates per 100mL of fluid.
• Consume your beverages at the coldest temperature you can tolerate - as this will help cool your body from the inside-out.
• IF YOU FEEL THIRSTY, YOU ARE ALREADY DEHYDRATED!
• After your workout, replenish with more fluids. You will know you are well hydrated when your urine is light yellow to clear.
• If your exercise session lasted for over an hour, and it was really hot, you may want to consider weighing yourself before and after exercise. You can assume any weight loss is water weight that needs to be replenished (consume 3 cups for every pound lost).

Humidity - In addition to temperature, humidity will also contribute to your body heat during a workout. Humidity will decrease the body's ability to dissipate heat (through evaporation) and will hinder the cooling process. I like this chart because it also mentions calculating the temperature to be higher if you are wearing thicker clothing or are in direct sunlight.

Target Heart Rate - If you work within a specific heart rate range during exercise, this would still be a wise suggestion while exercising in the heat. You will notice that your heart rate increases much quicker (in an effort to help cool your body). This means, you will have to decrease your intensity in order to keep your heart rate within the same zone.
Clothing - There is a reason dry wick clothes have been so popular - because they feel so much better! This is not the time of year to pull on your garbage bag sweat suit... and forget the cotton too, get some dry wick shorts and tanks in order to improve the evaporative heat loss from your body.
Sun Screen - If you have ever seen me exercise outdoors (no matter what time of year) my face is the color of a tomato when I am finished... but fortunately for me this is just temporary blood flow. Avoid any long-lasting redness or damage from the sun (ie: cancer and wrinkles) by remembering your sun screen! Here are a few reminders to make sure you get the maximum effectiveness out of your sun screen:

• Apply sunscreen liberally (should form a white film at first) 30 minutes before going in the sun to give time to absorb.
• Select an SPF between 15 and 50, depending on how prone you are to burning.
• Re-apply every 2 hours.
• Try to avoid the strongest rays of the day: between 11 am and 3 pm.
• Look for clothing that also provides UV protection.

Have fun in the sun, but make smart decisions to help keep your body fit inside and out!

Have a HEALTHY day!
