Welcome. We all do different things to lose the weight. After 20 years I've finally found what works for me. It may not work for you because we are all very much individuals that is why the diet industry is so lucrative.
I have read 2 great books YOU on a diet and Superfoods Rx. I eat every 2.5 hours. Foods high in nutrition, lots of vegetables, fruit, high fiber, fish and buffalo, lots of water and exercise daily. You wouldn't go a day without sleep why go a day without exercise. I will never gain this weight back. For the first time I am never hungry and my head is in the right place too. I wish you luck on your journey. I usually post in the 100 lb. club. I feel the most comfortable there.
