I know that the only thing that worked for me was the good old "watch what you eat" I lost weight by keeping track of every bite of food (even when I didn't want to) and moderate exercise (30-45 min) about 5 days a week. Having said that, my body does not give up weight easy - it took me 6 weeks to lose the first 2 lbs. I found that my body would only shed 5 lbs per month - It took 6 months to lose 30lbs. It definitely was a lifestyle change. I kept that off for 7 years - then had some back trouble and a surgery - and the old bad habits crept back in. The sad thing is I gained back twice as much weight - it is more difficult this time but I know that it will work - just getting myself into the frame of mind to make the correct healthy eating decisions. Its not easy so I understand the frustration.
