Weed used to give me the munchies all the time, but recently it's been doing the opposite. (At least I think that's what it's from.) I smoke quite a bit, and I've noticed the more I smoke, the less appetite I have. This works out great for me as I love the dope and I needed to lose a bit of weight, anyway. All in all, I lost about 25 lbs in roughly two months... Not sure if it's the diet for everyone, but it worked for me. Good luck, bro.
