Essential Nutrition
By Bryan Payne Certified Fitness Nutritionist

Over the years, and after working with many clients within the realm of Fitness Nutrition and Fitness Training at PayneFitness Health & Wellness, I have found that poor eating habits are the leading reason for failure in attaining and sustaining optimal fat reduction and improved body fat percentage. It’s important to note that an individual CAN improve their health vitals such as resting heart rate, blood pressure and heart stroke volume if they consistently embark on a vigorous resistance and cardiovascular training regime but, if their nutritional habits are consistently inconsistent IE; Eat good one day, eat bad 3 days, eat good one day, that they will struggle with substantial, sustained fat loss. To eat good means to eat in a manner that does not promote acute fat storage or acute muscle loss. To eat bad means to eat in a manner in which acute fat storage occurs (fat is only stored acutely) or to eat in a manner that promotes acute muscle loss.

There are many reasons for not following a healthy diet; I have noticed that a lack of knowledge combined with an abundance of misinformation, tend to be the most common reasons. With that in mind, I decided to write this article to “demystify” nutrition and to educate you in regard to the physiology of human digestion and how it affects your body fat percentage and state of physical fitness. We have learned that people learn more easily with the use of analogies. Due to the fact that everyone is reasonably familiar with how automobiles function, I have chosen to use them as the “vehicle” so to speak to make this information even easier to understand.

Due to the fact that we are bombarded with so much nutritional information, it is very difficult to decipher whether the source is legitimate or not. All of the information in this article was based on clinical studies, which was learned from the successful Registered Dietitian that administered the Fitness Nutrition Certification that I procured.

The most common question I get is “what and when should I eat?” There is a wealth of contradictory nutritional information available including: eat carbohydrates or don’t eat carbohydrates; eat before going to bed, do not eat three hours before bed, or do not eat after 6 p.m.; combine food, or do not combine foods. It appears that there is no end to this litany; with that said, you should ignore the folklore, myths and hype and get your nutritional information only from a reputable source.

Most of my clients’ and most peoples’ goals are to gain or maintain their muscle mass and get rid of unwanted body fat. Even though someone may think that this is mostly an aesthetic concern, the fact of the matter is that body composition or body fat percentage is a true measure of health as opposed to how much we weigh. We are not too concerned with how much you weigh, and neither should you. It may be surprising, but did you know that a pint of water (2 cups) weighs a pound; and that you may gain or lose a pound or more of body weight based on your hydration status and daily fluid intake. So, your success or progress cannot be based on your body weight alone. If I were to weigh you, have your drink a pint of water, and then weigh you again, the scale would indicate that you are a pound heavier. Does this mean that you are fatter? The answer is obviously no! You will just be less thirsty, and a pound heavier!

As you begin an exercise program, your body will start to store more “fuel” within your muscle cells. This fuel is called glycogen, which, simply put is many glucose or blood sugar molecules hooked together and stored in your muscles and body cells for later use. These glycogen molecules are so highly concentrated (thick) that your body must also store water in your body cells along with glycogen in a ratio of 1:3 (one molecule of glycogen to three molecules of water). Because water weighs a pound for every pint and glycogen also weighs considerably, your weight is sure to increase as you increase your exercise levels, as your glycogen and water storage increases in response to the increase in exercise.

An analogy will help to illustrate this phenomenon rather easily: If your fuel tank is on empty and you are going on a long trip by automobile, you will most likely fill up your tank. However, if your tank is on empty and you are only going to the corner store, you will most likely not go out of your way to fill up your tank. The same is true with your glycogen storage; the more you exercise, the more your body will begin to store glycogen and water. We know that your car does not weigh as much when it is empty as it does when it is full. So, does this mean that a car “gets fat” every time you fill up the tank? Of course not! A car has only one gas tank; the human body, on the other hand, has thousands of cells that fill up with glycogen and water for you to use as fuel the next time that you exercise, causing an increase in body weight, but not necessarily as body fat. The only way to know the difference between gaining weight of fat and keeping or gaining weight of muscle is to track your body fat percentage by measuring it weekly.

When looking at your body composition/body fat percentage weekly, we must look for the following four signs:

• A gain in muscle and a loss in fat = you have a perfectly designed meal plan

• A gain in muscle and a gain in fat = the meal plan includes too many calories, probably from carbohydrates

• A loss in muscle and a loss in fat = you are eating enough calories, but may not be eating enough protein.

• A gain in fat and a loss in muscle = you are either not eating enough protein, not enough calories or both

This is why it is critical to meet with your Certified Fitness Nutritionist (CFN) or Registered Dietitian (RD) weekly for the first month of the program so that a “baseline” is established in regard to how your metabolism is working and how it reacts to the nutrition and exercise plan that was introduced and implemented.

Typically, a month of weekly follow-ups is sufficient for making adjustments until the correct trend of gaining or maintaining muscle while getting rid of fat is established. Once this happens, a biweekly meeting with your CFN or RD is adequate for ensuring that the trend continues. Once you have reached your goals(s), you can meet once every three to four weeks to make sure that you continue down the correct path and/or establish a maintenance program depending on what your goals may be. Finally, you should consult with your CFN or RD as you establish new goals, or as your workout routine and schedule changes.

In helping my clients to achieve their goals of gaining muscle and losing body fat, I teach them three basic rules of success that are easy to follow no matter where their travels may take them. Before we discuss these rules, let’s first review some basic nutrition information as well as the mechanism by which fat is stored in the human body.

Food consist of three macronutrients (they are so called not because of their size, but because of the amounts in which we need them), by name they are, carbohydrates (CHOs), fats, and proteins. Whenever we eat CHO’s they first go to the stomach where they are digested, and then continue to the intestines where they are absorbed into the bloodstream in the form of glucose (blood sugar or blood glucose). As blood glucose levels rise, the body secrets insulin, a hormone that is responsible for storing glucose in muscle and organ cells in the form of glycogen. Normal blood glucose levels are between 80 and 120 mg/dl (milligrams per deciliter, a way of measuring glucose concentration or “how thick blood gets”). Whenever blood glucose levels fall below 80 mg/dl the body would react by slowing down its metabolism to save energy. Continuing with our car analogy, it would be similar to letting off of the accelerator pedal and turning off the air conditioning in our car to conserve energy when we are running low on fuel. Of primary importance to us however, is the fact that whenever our blood glucose levels rise above 120 mg/dl the residual/extra glucose is stored as fat! With this fact, the secret to dietary success is to control blood glucose levels throughout the entire day as a means of maintaining a high metabolism and therefore minimizing fat storage. The practice of maintaining normal blood glucose levels alone will have the secondary benefit of helping you avoid food cravings and overeating.

Due to the fact that blood glucose control is very important in controlling diabetes, many studies have been conducted to determine how different foods affect blood glucose levels. One study is the “gastric emptying time test,” which measures how long it takes for food to leave the stomach. The reason that this is a very important study is that the more quickly carbohydrates leave the stomach, the more quickly blood glucose levels rise. Usually, the more quickly blood glucose levels rise, the more effectively glucose gets stored as fat due to the larger insulin secretions, and because of these larger insulin secretions, the more quickly blood glucose levels drop (right after the insulin secretion causes blood glucose to be stored), causing us to get hunger pangs and/or cravings. Gastric emptying time studies show that the longest time that CHOs will stay in the stomach is one hour. In contrast, protein will stay in the stomach for two hours, and fats will stay in the stomach for three to five hours. This is why you will find yourself getting hungry 20 to 40 minutes after having a piece of fruit, or some bread, pasta, rice, veggies or even some cereal. This also explains why you feel stuffed for four hours after having a high fat containing meal. These studies also found that when you combine a protein with a carbohydrate, both the protein and fat contained in the protein (since most proteins have some fat in them) cause the carbohydrate to stay in the stomach longer (approximately three and a half to four hours), which basically means that this will increases gastric emptying time, a good thing because a longer gastric emptying time also means a slow and controlled increase in blood glucose, which lessens the chances of storing a large portion of this meal as fat due to a quick and high increase in blood glucose followed by a large secretion of insulin. A longer gastric emptying time also means mild successive increases over time, as well as mild or slower successive decreases in blood glucose levels caused by the longer time that it takes for food to leave your stomach. As a consequence, you do not get hungry as quickly, and are able to do away with your sweet cravings, which are usually caused by the need to raise low blood glucose levels after such a drop as described above occurs.

With the understanding of gastric emptying, it makes sense to eat protein every time that you eat a carbohydrate. In this way, you will increase your gastric emptying time, temper blood glucose swings, and control your appetite/cravings. This brings the question, “what is a protein?” Even today with all of the fad protein diets, some people are still confused about the difference between a protein and a carbohydrate. It’s actually very simple: If it walks, swims, flies, looks back at you, or shows you its teeth if you corner it, it is a protein. This means that even if you have a “beef” with “beef”, you can eat chicken, alligator, bison or wildebeest; if it comes from a plant or grows out of the ground, it is a carbohydrate. I’m pretty sure that vegetarians and other readers are probably squirming at this broad brush generalization. It’s true that beans are high in protein, as are many other legumes, plants and even some vegetables. But, in an effort to simplify things and to justify our generalization, we have looked at the largest component of a food, and the foods are grouped based on this component.

This means that even though a 1-cup serving of beans has 15grams of protein, it also contains 40grams of carbohydrates – beans are therefore deemed a carbohydrate. In an analogous fashion, although an avocado is a fruit, because of its high percentage content of fat, it is considered a fat. Another example of a caveat is milk, yogurt and buttermilk which all come from cow’s milk. Even though cows are protein, there milk products are carbohydrates due to the fact that milk has way more sugar than protein.

Given the short gastric emptying time of carbohydrates, it is no wonder that you can be hungry by the time that you get to the office after having a bowl of cereal with milk, a couple pieces of toast with jam or jelly, and a glass of OJ! These are all carbohydrates that leave your stomach quickly and raise your blood glucose levels quickly, which causes an insulin secretion that most likely stores everything you ate for breakfast as fat, and in doing so, causes your blood glucose levels to rapidly drop. You then go on without eating until 1 or 2 p.m., further slowing down your metabolism (remember, low blood glucose levels cause your metabolism to put on the brakes), which will most likely cause you to overeat at lunch, or if you are “disciplined enough” and just have a salad for lunch, by the time you have dinner at around 7:30-8pm you find that you are feeling starved and cannot be satisfied no matter what or how much you eat.

But wait! Stop! Hold the presses! You have probably heard (somewhere along the way) that you are not supposed to eat after 6:00pm? So, this means that you may as well go to bed hungry. Because, once you fall asleep, you won’t need any energy will you? Actually, the fact of the matter is yes, you will need energy while you are at sleep to repair tissues, and to conduct many types of metabolic functions that take place while you sleep of which muscle tissue repair is one. All of these processes require energy. Said again, the “no food after 6:00pm” theory is another myth, fallacy and rubbish. The fact of the matter is that the human body will do anything it takes to survive; that is the body’s number on priority. Due to the fact that fat is long-term stored energy, the human body will bypass burning fat in the short term and will initiate a process called “gluconeogenesis”, which simply means “the formation of glucose”. This sounds harmless enough until you realize that the pathway in which new glucose is formed is through the secretion of cortisol, a hormone that is responsible for breaking down muscle tissue and turning it into sugar or glucose so that you can continue to breathe, walk, talk, think, exercise, etc. So even though you may think you are not eating, you actually are eating – you are eating your own muscle! –muscle loss, reduction and deterioration equates to slowing your metabolism which equates to storing more fat. These are certainly undesirable effects. Due to the fact that muscle weighs more than fat (muscle takes about two-thirds less room than fat for the same weight), as you eat your muscle you lose weight, meaning, there is no reason to get excited about seeing lower numbers on the scale! In the worst case scenario, your body may be entering a downward spiral of continual fat storage and a suppressed metabolic rate…. This is something everyone needs to seriously think about.

Based on gastric emptying studies and blood glucose control, there have been three basic rules created to help you keep your muscle mass and get rid of fat. Rule No. 1 is to eat every three and a half to four hours, whether you are hungry or not. Again going back to the car analogy, you probably would not drive your car until you run completely out of fuel and have to call AAA or a friend to come rescue you…At least we hope you don’t allow that to happen too often. The same applies to your body and metabolism – you want to avoid continuously running out of “fuel” and having a candy bar, soda pop, ice cream or chips coming to rescue you either. The strategy and focus is to control your blood glucose levels throughout your day as to prevent crashing and craving cycles. Rule No. 2 – the most important rule – is to eat protein every time that you eat a carbohydrate. But of course, we want the protein to be low in fat. Before we get to the third rule, let’s discuss carbohydrate servings. As blood glucose control is the most important aspect of a nutrition and exercise program, and due to the fact that carbohydrates are the only one of the macronutrients that substantially effect blood glucose levels, we need to be able to determine what an appropriate portion of carbohydrates is. In addition to portions of carbohydrates, we must also define a portion of protein and a portion of fat so that we not only control blood glucose levels but that we control caloric intake as well. It’s fortunate that the American Diabetes Association, along with the American Dietetic Association (both are abbreviated ADA), have taken care of this for us.

There was a study conducted that determined how small of a carbohydrate dose it would take to raise blood glucose levels by a measurable or noticeable amount. It’s important to note that body fat is acutely stored when your blood glucose levels shoot up too high too fast! It turns out that it took exactly 15grams of carbohydrates to do it. Due to the fact that the word “serving” has already been previously used by millions of manufacturers of food products, the ADA’s could not just redefine the word serving. The ADA’s decided to come up with their own terminology and decided to call a 15gram serving of carbohydrates an “exchange”. Therefore, even though an entire English muffin may be one serving according to the manufacturer, since it contains 31grams of carbohydrates it is considered to be two carbohydrate exchanges. So, instead of having a cup of oatmeal every morning, you’re actually having two carbohydrate exchanges. (1/2 cup of oatmeal = 15g of carbohydrates or 1carbohydrate exchange) You may choose oatmeal, bread, cereal, pasta, rice, potatoes, pancakes, muffins, etc., until you reach the allocated/prescribed number of 30grams of carbohydrates or two exchanges or as many as your CFN or RD recommends you have for that particular meal. It is import to note that when we cook carbohydrates, that they usually expand (rice triples in size, pasta, oatmeal, etc doubles), and meats shrink approximately 20%. Due to this, we measure all foods after they have been cooked. There is an exception to this rule which is oatmeal. Since people have so many different ways of making it, soggy and watery, stiff, like cement etc, we measure oatmeal before it is cooked; in this way, it does not matter how much or how little water

There truly are a correct number of carbohydrates, protein, and a fat exchange’s that an individual needs per day to reach their health and fitness goals but, it is not a one-sizefits- all 40-30-30 or 60-20-20 recommendation. Therefore, Rule No. 3 is to become aware of what an exchange is and how many you need per day as well as in what combination. To determine exactly how many carbohydrate exchanges you need per day, as well as how many protein and fat exchanges to combine them with, we really need to go through a nutritional assessment that takes approximately one and a half hours. In this assessment, your basic metabolic rate (BMR) will be determined. A CFN and/or a RD can simply use a formula to estimate your BMR. This formula takes into account your gender, present weight, height, and age. Your basic metabolic rate will indicate how many calories you minimally need to survive. Once your BMR is calculated, the next step is to calculate your sedentary activity calories, in other words, how many calories you burn being yourself. The calories/energy calculated in this measurement does not take into account calories burned from exercise, only the activities of daily living are considered. Once we have determined the amount of calories spent in activities of daily living, the next step is to determine how many calories you actually burn while exercising. The amount is calculated using a value of calories per kilogram per hour so that we know exactly how many calories you burn during specific exercises, we can figure out how many calories you burn during weight lifting, interval training, spinning, swimming or running a ½ mile for instance. Once we have calculated all of the above calories we then add your specific value for what is called the thermal effect of foods, which is a measure of how many calories you burn keeping warm and processing, digesting and absorbing your food. The next and final step is to design an ideal meal pattern or plan for you.

A qualified Fitness Nutritionist or Registered Dietitian can put together a sound meal plan based on all of the above data which will let him or her know how many exchanges of carbohydrates, protein, and fat that your body requires for optimal performance, fat riddance and muscle maintenance/gains. The number of carbohydrate exchanges you will be eating per day will depend solely on your weekly cardiovascular and daily living activities – just how active you are. In contrast, the number of protein exchanges that you will be eating per day will depend on your body weight as well as the type of exercise routine prescribed to you. If you already have and establish exercise routine, the CFN or RD will take it into account to ensure that your body is fueled adequately for the activities. Last but not least, the number of fat exchanges that you will consume each day will be equivalent of 15 to 30 percent of your total caloric intake. Such a balanced meal plan will ensure that you attain your goals of gaining or maintaining muscle mass while getting rid of body fat.
For a quick review, here are the three rules and things to consider:

1. Eat every three to four hours; hungry or not!

2. Every time you eat carbohydrates, make sure to eat them with protein.

3. Find out what an exchange is, and how many you get per meal/day.

4. Meet with your CFN or RD weekly to monitor your progress and make necessary changes to keep you on track for attaining your goals.
