Some people don’t mind being fat. Other people can keep slim (苗条) without any effort. But a lot of people do put on too much weight and don’t like it. The question is, what can thy do about it?

Some believe exercise can be helpful. But the trouble is that it only makes you want to eat more. You might sweat out a couple of pounds playing tennis or climbing a mountain, but you put it all back on again with a big steak or bread and jam.

A helpful way is food choosing. But what sort of food should you choose? Some believe that the less they eat, the slimmer they will be. They don’t eat anything until they become weak with hunger. Some stick to milk and bananas. You’ll find you need a lot of bananas, and unless you live where they grow, they aren’t cheap. Another says that if you eat things like hard-boiled eggs, and apples with their skins on which are hard for your stomach to digest (消化), 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 (极端的). The simplest way is just to cut down on the carbohydrates (糖类) that means not eating bread, potatoes, cakes, sugar, rice, and so on and eating anything else you like. It’s straight forward and often quite effective.

Still others like to be more scientific. They are calorie countries. They get a table, which tells them that, for example, 100 grams of roast let of lamb gives you 330 calories and a 50 gram helping of Yokshire pudding gives you 130 calories.
