I agree with omega drugs is not the way. Suppressing appetites is not good as you are depriving your body. Healthy weight loss is not about depriving but by changing eating habits, as even if you reach your goal, if you revert back to your ld eating habits, won't be long before you are back to square one.
When you decide you want to loose weight, yo are making a life changing decision, i.e to not come back where you are currently. This means once goals have been reached you then need to maintain. Thats can be the hard part for some people. I think this is more about will power and mind sets. If you are determined to loose weight you will, but what people forget about is that habits need to permanently change to maintain a healthy weight.
