I have been sugar free for 4 weeks, doing loads of reading, and watching links on sugar etc. I have definitely felt several benefits from giving up the addiction. Once the initial headache from hell, and flu- like sensations left my sorry being, my Joints are better, aches in the bones have gone, more energy, more active, and clear headed - marvelous! However, my worst hang up is that I am obese, and have not lost any weight! My appetite has definitely decreased, and for the very first time in my life I have experienced the sensation of being full in the middle of a meal. So i don't think I am any longer over-eating. ...And still no weight loss. I have counted calories, and am having under the requirement of 1200 per day (sometimes as little as 800) and not having any hidden sugars, and limit my fruit intake to 1 piece of fruit a day, but in reality, it's been more like 3 pieces in a week. Can someone give me some information regarding leptin and any other information that may help me to kick start a weight loss. I am worried as around about now I usually give up with diets, but I really don't want to give this up, as I know it's good for me. I am in my fifties now, and don't want to be old and fat and unhealthy.... Please help me!
