I was on a very strict diet for 6 weeks. This diet, per doctor's instructions, must then take a break for 4-6 weeks and then you re-start if you wish to continue weight loss. I did two rounds of this diet. During first round, I lost 25#s. While on the "break", I regained 5#s! Fearing the same would happen after completing restricted diet - gain back my weight loss - I did some research on "how to maintain weight after resuming a normal, reasonable diet. I came across Leptin and learned that this meant the brain would receive a message saying, in my own words, "Brain, stop, you were not starving". Per Leptin's research explanation, "Leptin is a hormone that tells the brain when enough fat is stored, preventing overeating and aiding in healthy calorie burning. Leptin resistance can cause the brain to miss this signal, which may contribute to obesity." I have been on Leptin for two months after strict diet and have not felt hungry, I don't feel I have to make up for lost eating regimen, no binging, etc. My brain's messages are no longer about food! I concentrate on chores, exercise goals, etc. Very happy with product. Remember, it is not for weight loss but for your brain to know you were never starving and body does not have to binge! I've had 3 bottles and ordering a fourth bottle today! Good Luck ALL!
