Formax Lean Think realistically about how much change each of those areas can withstand. For example, if you do no exercise at all, you're going to struggle with a weight loss program that requires intense exercise from the get go. If you eat out regularly, you'll need a diet that allows you a wider choice of food types to accommodate that. Counting calories can be time consuming, so if you have a busy schedule, you may want a diet that either lays it all out for you, or gives you more flexibility.
