some people don`t mind being fat. in some countries a round stomach is nothing to be ashamed of. there is a west african saying:"laugh and grow fat." other people can keep slim without any effort. but a lot of people do put on ,too much weight and don`t like it. the question is, what do they do about it?
some people put their faith in exercise. but the trouble with exercise is that it only works up an appetite. others believe in slim pills and special clothes that make you sweat. it would be nice if they worked, but they don`t.
the only reliable solution is dieting. but what sort of diet? there are the extremists who believe in a dramatic, thorough-going attack on their waistline by eating nothing. there is another theory that if you eat things like hard boiled eggs,apples with their skins on, and lean meat which are hard to digest, that the more you eat, the thinner you get.
this is because you use up the fat in your body to get the energy to digest the food. for most of us these methods are too extreme or too eccentric. the simplest system is just to cut down on the carbohydrates or, if possible, to cut them right out.
