I know this has been part of discussions regularly so apologize for recycling a topic. I started seeing a new doctor last week (I call her the witch doctor because she's a naturopath. then again I have a weird sense of humor ) and she was concerned about my calorie intake vs. exercise. She thinks I should still be losing (I'm not trying to) but I'm not. I think, based on everything I've read here and elsewhere, including Thin for Life, that maintenance after a lifetime of obesity has its own rules that are different than for someone who has never been seriously overweight.
My daily caloric intake is between 1300 - 1500 and I get at least an hour of cardio in at least 5 days a week, at least one 90 min. yoga class, work with hand weights, and some targeted stretching/strengthening for my back & abs. At that level I maintain. If I change either of those things I gain (I learned that the hard way by regaining 6 lbs in the fall).
What do other maintainers do?
