Why are fat diets more likely to harm than to help? The reason for that is we have to return to the set point or the weight set point theory. Then one goes on a fat diet that usually involves a significant reduction in the amount of calories you're taking in. How does your body respond to that sudden reduction in calorie intake? Very simple. Your metabolism slows down to compensate for the reduction in calorie intake. What happens then is the physiological compensatory mechanisms kick in. You develop increased levels of hunger, which happens to all of us when we've tried a fat diet. It's very hard to fight the hunger and the urge to eat. Eventually, the diet fails because the hunger sensations are so strong and the drives to eat are so strong. So you go back and resume your old eating habits. Your calorie intake then increases back to what it was, usually even more than what it was but what happens unfortunately is your metabolism doesn't go back up to what it was before. It stays depressed and hence the fat diet will when it fails lead you to put on not just the weight you'd initially lost on the fat diet plus also you will gain some extra weight and we call this the yo-yo effect of dieting especially through fat diets. you
