As far as I can see Lipovon is just another fad "diet pill", produced by a Mexican company. It is labelled as a "diet supplement" which means that it is not subject to standard regulatory approval in the way in which evidence-based medications are.

I think that the others have offered you great advice - eating in a healthy way (not a "diet") and regular exercise is the way to sustainable weight loss.

It might help if you saw a qualified dietitian. Dietitians are health professionals who can offer their clients advice about healthy eating.
