weight loss supplement for me

My friend is bragging about how much weight she lost through workout and healthy eating. She told this while we were feasting because it was our team leader house blessing. As for me who getting bigger and there eating with them felt quite ashamed of myself, but theres nothing I can do to refrain myself from the food because I was starving since breakfast.
She actually told us that the best way to really loose weight is workout and  take best weight loss supplement. But hubby won't allow me to take some pills due to we are trying to get me preggy as always. So we won't take any risk specially this time.
