i think everyone has heard about it......90% of what is put out is fake though, you have to be careful to get the real one......but anyhow, hoodia is an apatite suppresent from south africa.....i dont think that it is a good idea to not eat when on a diet....you need to keep you metabolism working so it can burn fat off, witch means you need to eat about 6 times a day....but small, health meals.
