And I just wanted to know what's a 1500 calorie diet good for me?

Can't hurt. In many cases the low cal diet can signal to the thyroid that you are in starvation mode thus preventing weight loss. A surer way to lose weight is by eating a meditteranean style diet minus any grains containing gluten and including low glycemic foods. Eating 3 meals and 2 snacks may show more results than calorie counting. Let me know how you do. 1500 cals is safe and effective.
