Hi, just started back after four months, gained 6.6 lbs since the beginning of the year, so now I'm starting over again. At 58 yrs old I'm still learning to control my food intake, its a lifelong journey. I do have some good news, bought a treadmill for my birthday and I'm training for this year's marathon. Losing weight would no only help my self-esteem and body image, but my ability to run 13.1 miles. I've got 6 months to prepare, any advise?
