I myself use Trimspa and lo carb. I have lost 50 lbs since March of 2004. I am not using it to NOT EAT. I use it for the energy it gives me to get through my day. I have MANY health problems and doctor every 3 months at the Mayo Clinic in Rochester, MN. Although they don't like the idea, it keeps me going where other methods they have tried due to my illness does not. I still eat 6 meals a day but I drink A TON of water due to one of my illnesses, (no its not diabetes). I still have days where no matter what I do, I feel dead. I still think my weight loss is due to Atkins NOT trim spa. I do take it tho and well.....thats that. Hope that helps
