Here is an article we wrote on cannabis and weight loss:

I can not recommend an edible, as from what many people say, it is highly dependent on the strain you ingest, so you would need to know that. Most edibles do not tell you what strain they are using. What you are looking for is the higher profile of the cannabinoid THCV, which suppresses appetite.
Strains that are better known for appetite restriction are: Alpha OG, Cherry Pie, Pineapple Purps, and Durban Poison.
So to answer your question, you might have to smoke or vape a flower with higher levels of THCV.
I hope this helps!
