For Optimum Performance & Conditioning…Fuel Your Muscles With Fat!

Part 1 of Series:

Science has long since known that the potential energy contained in one gram of fat is equivalent to nine calories, whereas protein and carbohydrates yield only four calories of energy per gram.  Given this nutritional fact it has always seemed strange that the athletic community heavily emphasizes the use of carbohydrates as a primary fuel source in preparation for and during competition.

In order to achieve peak performance and conditioning, it is essential that an understanding of basic energy metabolism first be obtained.  To give you an example of the available energy stored within the human body (in the form of body fat), consider an individual who weighs 200 pounds and has approximately 20% body fat.  When calculated, this individual has about 40 pounds of stored body fat, with approximately 160 pounds of lean body mass.  Once oxidized, each pound of stored body fat yields approximately 3,500 calories of potential energy, equivalent to about the amount of energy expended by a 150 lb male walking at a speed of 2.5 mph for 13.25 hours.  To further calculate the approximate amount of total fat energy stored by the same individual, we would simply multiply 40 pounds of body fat by 3,500 Calories/lb.  This would then yield a grand total of 140,000 stored calories of energy equivalent to approximately the same amount of calories expended by a 150 lb male walking at a speed of 2.5 mph for 531 hours!

Since body fat provides nearly three times the amount of ATP (adenosine triphosphate, the energy source for muscular contraction) when compared to protein or carbohydrates, it would only make sense to promote and encourage the utilization of body fat as the primary fuel source for muscular contractions (instead of muscle glycogen and amino acids) especially during competition.

Although this seems to be a very simple thought process, achieving the objective is not quite as easy.  The reason being is that for every pound of fat burned in the muscles, a proportionate amount of glycogen (carbohydrate) is required to be burned as well.  In other words, “fat burns in the flame of carbohydrate!”

Principles of Endocrine Physiology…What is an Islet Cell?

The INTRAFITT Individualized Nutrition and Exercise Program was developed and established in California- 1992 in an effort to educate individuals seeking optimal levels of health, fitness and performance on the effect that diet and exercise has on the major regulatory systems of the human body (Nervous System and the Endocrine System) and their consequential effects on the Re-Programming Aspects of the Human Body.

ORGANIZATION OF THE ISLET OF LANGERHANS

The “primary” pancreatic hormones, insulin and glucagon are two of the most powerful metabolic regulators concerning the metabolism of body fat, the maintenance of blood glucose levels and the production and maintenance of lean body proteins. As you will discover, the insulin/glucagon axis is perhaps the most important focus in the development of safe and effective weight management, health enhancement and performance nutrition programs.

The islet cells of the pancreas are composed of 60% beta cells (b-cells), the source of insulin and 25% alpha cells (acells), the source of glucagon. The remaining 15% of the islet cells secrete the peptides somatostatin, from the delta cells (d-cells) and pancreatic polypeptide from the F-cells. The strategic location of the islet cells reflect their functional role. Insulin, glucagon and the pancreatic enzymes are secreted in response to incoming nutrients from the diet as well as from gastrointestinal secretions, which ultimately reflect the concurrent nutritional status of an individual.

Additionally, the location of the islet cells force their secretions into the pancreatic vein, which integrates at the hepatic portal vein and empties into the liver (the central organ in nutrient traffic).

Insulin and glucagon coordinate the direction of incoming nutrients from the diet via the hepatic portal vein. Insulin and glucagon also control and direct the flow of endogenous substrate (once it has been broken down and released), such as stored body fat, glycogen and amino acids, derived from the protein structures of the body.

Since the liver is the first organ to come in contact with insulin and glucagon (once these hormones have been released by the islet cells), it is therefore exposed to higher concentrations of these hormones, then are the peripheral tissues (muscle tissue and adipose tissue). Consequently, the liver can very efficiently modulate the release of these two hormones to the peripheral tissues, therefore allowing for more or less of the hormones to circulate throughout the body.

NOTE: Due to the liver’s high exposure to insulin, it should be clear as to why fatty deposits can develop so efficiently within the liver thus contributing to the very prevalent condition know as Fatty Liver Disease.

Because Insulin and glucagon are secreted together and act reciprocally it is perhaps more beneficial to focus on the ratio of insulin and glucagon concentration in blood plasma, rather than the absolute concentration of each hormone respectively.

Nutrition: Are All Calories The Same?

Hi Everyone,
I wanted to continue on today talking about Nutrition in the  Simplest Form. Basically, there are six essential nutrients that the human   body requires to keep it nourished and healthy. These include Protein,   Carbohydrates, Fats, Vitamins, Minerals and Walter. The term “essential” is   used to describe these nutrients because they must be provided to the body in   order to sustain life and to prevent a deficient or diseased state. Of the   six nutrients listed, only three provide energy to the body, while the other   three help to release energy inside the cells. Typically, these two   categories of essential nutrients are referred to as the Macro-Nutrients (energy   providing nutrients needed by the body in larger amounts)and Micro-Nutrients (energy   releasing nutrients needed by the body in smaller amounts).

 The Macro-Nutrients, when metabolized provide energy and   heat, which are used to support all of the metabolic functions (heart   beat, digestion, muscle contraction, concentration and comprehension) of   the body and mind. The fuel potential of the energy nutrients is expressed   in calories Just as a meter is a measure of distance, a calorie   is a measure of energy and is defined as the amount of heat needed to raise   one milliliter of water one degree centigrade. Therefore foods that are high   in calories (dried fruits and nuts) are also high in energy, whereas foods   that are low in calories (strawberries, melons and vegetables) are low in   energy as well. Perhaps this is one reason why people who eat low-calorie   foods to lose weight have little to no energy to exercise in the course of   their day.

 You might wonder where calories are derived from. If you look   at this question from the standpoint that a calorie is defined as the total   amount of heat energy needed to raise one milliliter of water one degree   Celsius, then YES all calories when oxidized yield the same amount of heat   energy. Perhaps the question should be “are all calorie sources the   same?”

 Take for example the two individuals illustrated below. Each   individual has a recommended calorie intake of 520 calories per meal and both   eat the exact same foods within the meal. The difference however, is that   they each eat varying amounts of the food items listed and as a result end up   producing a very different endocrinological response. In other words, the   regulatory effect associated with the different amount and types of food   eaten can have a favorable or unfavorable influence on the metabolic process   and can last for three to six hours after a meal.

 Individual #1 (500 Calories per meal)

 6 oz Chicken breast: 186

7 oz Yams: 210

1 Tbs Peanut butter: 100

3 oz Broccoli 24

 Total: 520 

 

 Individual #1 (500 Calories per meal)

 8 oz Chicken breast: 248

2oz Yams: 60

2 Tbs Peanut butter: 200

1.5 oz Broccoli 12

 Total: 520 

 Now lets assume that the same two individuals perform   cardiovascular exercise for thirty minutes later that evening. As illustrated   below, Individual #1 exercises within his/her target heart rate while   Individual #2 exercises above his/her target heart rate. Although Individual   #2 likely burned more total calories than Individual #1 at the end of the   thirty minute session, they both theoretically burned the same amount of fat   calories.

 Some would argue that exercising at an intensity that is above   the recommended training sensitive zone (for fat burning) is more beneficial   because a higher number of calories are burned at the end of an equivalent   exercise duration. This is perhaps true, however, exercising at high   intensity, although may burn more calories, will more than likely train the   body to become more efficient at burning sugar than fat and may very well   promote hypoglycemic (low blood sugar) symptoms that can ensue for up to   twelve hours after the exercise session has ended. That is one of the reasons   I always recommend wearing a heart rate monitor when exercising.

 

Individual #1
