It sounds ridiculous and dangerous. You are messing with your body’s hormonal balance. There may (or may not) be a desired side effect of weight loss but there will also be others.
Habit changing – healthy eating, small food portions and exercise – are the [only?] things that work. It takes more effort and willpower than injections, but is longer lasting.
I know that weight losing isn’t easy. Hatzlocho!
