I can talk about diets

I never go on a diet; it's a waste of time. Diets list all the food that is good for you, but few people can keep them up. I haven't put on weight in twenty years. Here's why:

• I eat almost anything, but I don't eat a lot. And I don't eat junk food.
• I drink plenty of water. It's better for you than fizzy drinks, and cheaper too.
• I avoid snacks between meals because most of them are fattening.
• I've cut down on the amount of food I eat in the evening.
• I do/get plenty of exercise.
