Execise is health hygiene, its not a diet plan. This is obvious when you look at how hard it is to not eat a snickers bar vs how hard it is to burn off a snickers bar worth of calories via exercise. What you are talking about above is maybe a twenty pound seasonal discrepancy, it's not what most fat people are dealing with (also a quarter of that twenty pounds is just excess water you probably shed in the first week of adding back increased activity in the summer)
Its easy to not eat a snickers. To burn a snickers off through exercisw you are looking at a half hour to an hours commitment in the gym depending on what you are doing. You can override what most people call a weekly exercise plan with a couple snickers and a few fancy coffee drinks
Yah, sorry, I was also short for time to the point of extreme brevity but not to the point of delaying responses until I had more time for this whole thread. I should have also given the example of t he ideal male BMI being 18-25 so call it 22 and over 30 BMI being obese which, on a 5'10" person (pretty average for a male) corresponds to roughly 154 lbs vs roughly 205 lbs for a 50 lb spread. It's not the 10-20 lb spread that is probably seasonally normal. Trying to reverse that with just exercise is a gargantuan task, it's primarily diet that will reverse something like that (but you definitely should still exercise, it does all sorts of good things for your body on a reasonable schedule with reasonable recovery periods, especially resistance training, which is more true the older you are)
