I lost 60lbs in 10 weeks in the summer of 2006. I was in Idaho on an internship and weighed ~260lbs. I found the way to conquer my food addiction was to get it out of my life. I went to work at 7, came home at 5-530ish, ate a lite snack and immediately went to the gym. I exercised for 1.5hrs then would go get dinner at Subway (its a quick, cheap, and if you get just bread, meat and veggies as you suggested its low in calories). Then go somewhere other than home! I found the problem I had was in the downtime. I would eat for no reason, just because I was bored. Find something to do. I went to Barnes and Noble and read, or went to a movie, or anything but sit at home. I ate fruit and yogurt for breakfast, veggies for lunch, and Subway for dinner. It worked great and I went on to lose 30 more lbs after the summer before it was all over. One concern though, make sure you do get enough nutrition. One of the reasons I lost so much weight so quickly is because I was half starving myself, only eating about 1000 calories/dy. I stopped sleeping through the night and found myself in a haze all the time. I saw a doc and he told me to eat a cheeseburger and bring my calories/dy up. That was the best cheeseburger in my life, and the 12hrs of sleep after felt awesome. If you want to lose weight and are afraid of losing your willpower completely change up your routine and get into good habits. I say completely because if you dont change how you do things you will fall back into those habits. It only takes about 2 weeks before you get into those habits, and once you see weight coming off it will give you encouragement to continue in your new routine.
