Most of us equate the word diet with calorie reduction. This is understandable, since most diet marketing is relentlessly focused on offering consumers low-calorie options.Unfortunately, this way of thinking is categorically wrong. The simple fact that any nutritionist will verify is that everyone is on a diet. Even those who do not wish, or do not need, to lose weight are on a diet, as are those who are increasing their weight. Dieting has nothing to do with calorie reduction, and everythin.
