We could not assign scores to the cost of a plan, nor to exercise. Even dieters buying prepackaged meals from commercial programs have to shop for at least some food, and individual shopping habits and preferences, not to mention dining out, will heavily determine any dieter's total expense. Exercise gets serious attention in some diets and lip service in others, but the primary focus of a diet, after all, is food. Whether to exercise, how, and how much is a lifestyle decision beyond the scope of a mere diet.
What's next for Best Diets? We plan to scrutinize more eating plans and give dieters a way to plug in their personal preferences and requirements so they can zero in on diets that have the best chance of working for them. With diets, one size never fits all.
