Some people do not mindbeing fat.Other people can keep slim without any effort,but a lot of peopledo put on too much weight and do not like it.The question is,what can they do about it?
Some believe exercise canbe helpful,but the trouble with exercise is that it may only make you want toeat more.You might sweat out a couple of pounds playing tennis or climbing amountain,but you put it all back on again with a big steak or bread and jam.
A helpful way to loseweight is to carefully choose foods.What sort of food should you choose?Somebelieve that the less they eat,the slimmer they will be.They do not eatanything until they become weak with hunger.Some stick to milk and bananas.You will find you need a lot of bananas,and unless you live where they grow,they are not cheap.Another theory says that if you eat things like hard-boiledeggs,apples with their skins on,and lean meat which are hard for your stomachto digest,the more you eat,the thinner you get.This is because you use up thefat in your body to get the energy to digest the food.
