Obesity: Causes Most People Dont Know About

With all the emphasis on the importance of weight loss and dieting in the world today, obesity incidence is still rising. The diet industry generates billions of dollars annually and yet the majority of the money spent by consumers is wasted. Why is that?Why do people have so much trouble losing weight and even more difficulty in maintaining weight loss? Well, when we narrow it down, the problem lies either with the diet or the dieter. Lets look at the bottom line cause of weight gain or weight loss.If we look at the energy equation we find that when Input (food intake) exceeds Output (energy expenditure) the result is an excess of calories which are stored in the body as fat causing weight gain.When Output exceeds Input we have a situation where a negative balance occurs in the equation (the body burns more calories than it consumes) which results in weight loss.Its as simple as that. Obesity is caused by excessive calorie intake over a long period of time (when Input exceeds Output). This, however, is only ONE cause of obesity NOT the only cause.There are also other important factors related to obesity. Some of which people may not know.
