Do I have to consume all the calories on my daily meal plan?

Each person has different needs for weight loss and, depending on your own unique metabolism, will need different calories for weight loss. There are so many variables to weight management, but what experts will tell you is that you start at a certain amount, and customize as you go. So, for you, the best idea is to use the meal plan as a framework that you fill in with your own personal preferences. If you want to eat less, that is just fine! The idea is to eat enough to sustain your energy, and to promote weight loss - about 1-2 pounds a week. The calories assigned to you represent a theoretical number, but do modify as needed. Feel free to reallocate the foods - taking something from lunch to eat as a snack as an example. The idea is to find your own "perfect" diet, which after all, represents the foods and beverages for you to enjoy as you work toward your goal weight.
