Human weight control is a very complex problem. It is more complex than the idea that being overweight is simply due to an imbalance between daily food intake and energy expenditure. In a study 29 volunteers, all of whom claimed to be quite unable to lose weight on rigorous slimming diets were isolated in a country house for 3 weeks.
On arrival, luggage was searched for hidden food and car keys confiscated. All the volunteers were placed on the same 6300 kJ diet and their weight loss determined after 3 weeks. Nineteen of the twenty-nine did actually lose weight on this diet, but nine maintained their weight and two actually gained weights on what, for most people, would be a starvation diet. Those resistant to losing weight were found to have low basal metabolic rates. For more weight control tips, you can also navigate http://innovativewomens.com/.
Contrary to the popular belief, there is absolutely no valid scientific evidence that the obese eat more than the lean individuals. That was concluded that it is difficult to support the contention that food intake is the primary determinant of body weight in man.
The logical explanation for these anomalies is that either of two mechanisms must be operative. Humans must differ either in the amount of energy that they actually store from the food they eat or in the amount of energy they need to maintain a constant body weight that is their basal metabolic rates.
