No wonder with all that you put your body through as you get older, the harder it is to keep weight off. I remember in the past, I would not have to do much of anything to lose weight. Now it seems I do not have to do much of anything to gain weight. I would love to know how to master your metabolism because at this rate, any more fluctuating and I am bound to gain more then the 7 pounds that people of 30 gain in a year’s time. I need to break the cycle and manage the metabolism.
