My mom thinks I'm crazy...

So I'm only 21, and I'm barely overweight. Only by 7 lbs. But, I personally want to loose up to 15 lbs. I don't want to be anorexic looking, not even model looking. I want to FELL GOOD. That's my goal. In fact, I'm going more for muscle tone. Anyways, I talked to my doctor and I'm taking a pill prescribed by her that is all natural and a combination of natural herbs to help boost my energy. My mom thinks I'm completely nuts for it. She says, for one at my age and barely overweight I shouldn't be worried, and two, even if it's natural, I shouldn't be taking pills to help loose weight. It's not one of those things you get off the internet. This is medically prescribed and it's all natural or else I wouldn't take it! Sure it helps to make you eat a little bit less, but if also makes you sick if you don't eat. And the majority of it boosts your energy so you WANT to work out. Am I really crazy, or is my mom just being too.motherly?

Ok I wasn't clear about the type of pills I am taking. Their all natural herbs. And they don't loose the weight for me. Like I said before, it mostly helps to boost my energy so I want to exercise. I still have to make sure I'm eating correctly.
