We live in an addiction-prone society, but of all the addictions out there, one of the most deadly is one that is most often overlooked: junk food. The term “junk food” refers to any food that is high in calories, fat, salt, and sugar without bringing any nutritional value to the table. Unfortunately, this food is usually convenient, tasty, and extremely addictive.

There are times when it’s next to impossible to get in a freshly prepared, well-balanced meal that’s going to accommodate your muscle-building or fat-loss goals. Turning to fast or convenient food is often a very unwise decision, nutritionally speaking, which leaves you opting to choose a protein bar.

Unfortunately, most guys think they’re doing themselves a favor when they opt for a protein bar since now they have protein in combination with carbohydrates, which is much better than the rush of pure carbs attained with a cereal or energy bar. The truth is, however, that manufactured protein bars are often nothing more than glorified candy bars and are going to do nothing in terms of enhancing your physique.

THE STATISTICAL CHANCES OF SUCCESS

Did you know that 75% of the people who exercise are not achieving the results they want! But of the 25% who are getting the results they want, 90% are working with a Personal Trainer.

In scientific terms, a calorie is the quantity of heat required to raise the temperature of 1 gram of water 1 degree Celsius from a standard initial temperature. A nutritionist's calorie is defined as a unit of energy-producing potential equal to this quantity of heat that is contained in food and released upon oxidation by the body.

Food manufacturers are required to label their products with calorie guides. Calories of various products are determined through direct Calorimetry--that is, the measurement of the amount of head evolved or absorbed in a chemical reaction or change of state.

Energy-producing food is digested in the stomach and small intestines and eventually allows the body to build up muscle proteins, cleanse itself, strengthen bones and stabilize itself. Resting metabolic processes as well as growth mechanisms require energy, thus consume calories.

Body fat measurements and the measuring tape are recognized as superior methods for measuring "weight loss". When one declares that they want to "lose weight", what they often mean is that they want to lose fat. So, now that you've had your body fat percentage measured, what does the number really mean?
First, your body fat percentage is simply the percentage of fat your body contains. If you are 150 pounds and 10% fat, it means that your body consists of 15 pounds fat and 135 pounds lean body mass (bone, muscle, organ tissue, blood and everything else).

A certain amount of fat is essential to bodily functions. Fat regulates body temperature, cushions and insulates organs and tissues and is the main form of the body's energy storage. The following table describes body fat ranges and their associated categories:

*General Body Fat Percentage Categories
Classification Women (% fat) Men (% fat)
Essential Fat 10-12% 2-4%
Athletes 14-20% 6-13%
Fitness 21-24% 14-17%

There are races of people who are all slim, who are stronger and faster than us. They all have straight teeth and perfect eyesight. Arthritis, diabetes, hypertension, heart disease, stroke, depression, schizophrenia and cancer are absolute rarities for them. These people are the last 84 tribes of hunter-gatherers in the world. They share a secret that is over 2 million years old. Their secret is their diet- a diet that has changed little from that of the first humans 2 million years ago, and their predecessors up to 7 million years ago. Theirs is the diet that man evolved on, the diet that is coded for in our genes. It has some major differences to the diet of "civilization". You are in for a few big surprises.

The diet is usually referred to as the "Paleolithic Diet" referring to the Paleolithic or Stone Age era. It is also referred to as the "Stone Age Diet", "Cave Man Diet" or the "Hunter-Gatherer Diet". More romantic souls like to think of it as the diet that was eaten in the "Garden of Eden" and they are correct in thinking so.
