If you're looking to lose weight, this works:

Google "BMR Calculator" and in the calculator, enter your GOAL weight (not current weight). It will give you the calories need for your Basic Metabolic Rate. Limit your caloric intake ....don't exceed that daily caloric intake.

Take a multi-vitamin.

Exercise is always healthy but optional for this "diet."

This works for me, but I'm not a doctor. Consult with your doctor before embarking on a diet. I like the flexibility of this plan...BMR goal weight calories. It's not a diet, per se, just a way I thought would work for me. It's best to ask your doctor what is a safe diet for you.

I haven't ever taken diet pills.
