I hope the Swedish bitters will help me. They are inexpensive and easier to take compared to other stuff like Chinese Bitters.
I am thin naturally (I weigh 105 lbs and am 5'1"). I think it's Genetics. But because of health reasons (years of eating fast food and junk food has caught up with me - food allergies , chronic fatigue, insomnia) I am now a health nut: I avoid junk food and I try to exercise regularly.
I've noticed that people lose a lot of weight on the Master Cleanse. (That's why I can't be on it for too long, since I'm too thin already). My friend lost about 20 lbs in 2 weeks. Perhaps you could try that. It also cleases your insides: detoxes, and heals your body.
