When we discover that we are heavier than we want to be, we have a natural invlination to eat less food. We may skip lunch or eat only a tiny amount of our dinner in hope that if we eat less our body will burn off some of its fat. But that is not necessarily true. Eating less actually makes it more difficult to lose weight.
Keep in mind that human body took shape millions of years ago, and at that time there were diets. The only low-calorie event in people's lives was starvation. Those who could cope with a temporary lack of food were ones who survived. Our bodies, therefore, ahve developed this built-in mechanism to help us survive in face of low food intake.
When researchers compare overweight and thin people, they find that they ear roughly same number of calories. What makes overweight people different is amount of fat that they eat. Thin people tend to eat less fat and more complex carbohydrates.
Losing weight is not something one can do overnight. A carefully planned weight loss program requires common sense and certain guidelines. Unfortunately, there's a lot of misinformantion floating around and lots of desperate people are easily duped and ripped off.
Every day one can open a magazine or newspaper and see advertisements touting some new product, pill or patch that will take excess weight off quickly. Everyone seems to be looking for that "magic" weight loss pill. Millions of Americans are trying to lose weight, spending billions of dollars every year on diet programs and products. Often they do lose some weight. But, if you check with same people five years later, you will find that nearly all have regained whatever weight they lost.
