The only thing my mother and I ever had lasting success from was a program called Columbia designed by Doctors she discovered through the other nurses in her hospital over twenty years ago! Today she is into the South Beach because it deals with the hunger, the sugar levels, and how to control them to prevent cravings. Be warned: high protein-low carbs diets are for temporary purposes and can cause more serious problems if you remain on them more than a few weeks by depleting your liver's store of sugar and creating nervous system problems. This is not just a little side effect, it can be a warning sign. Eat small bits more frequently and always start the day with raw foods plus complex carbs. I am currently taking LA Sport which is antioxidants, potassium, and caffeine plus a little more. It is mild, has increased my energy levels, did not affect my concentration much, definitely cut my appetite way down, and you can start low and up the doseage 6xs. Plus, I got it at the Dollar Tree for a fraction of the cost. Slimfast Cookie Dough Meal Bars Rock!!!
