I think I wrote most of what I have to say on this subject, a couple of minutes ago in reply to another of your Threads on this topic.

Despite the fact that you're walking a couple of times a day, if you're gaining weight, you must be eating too much for the amount of exercise you're getting. Of course, not getting enough sleep can also be a complicating factor here. If your eating habits are a response to depression, then perhaps it is necessary to treat the depression before you can hope to successfully stop overeating. However, it is true that, if you have no motivation of your own to lose weight, & you're mostly just trying to do it because others say you should, you're probably unlikely to succeed. Food is simply too alluring.

Perhaps if, at some point, you decide you really do want to lose weight, then a weight loss program might be the way to go. This would provide you with the structure & the tools to lose your excess weight. Really, though, losing weight, & keeping it off, is a real challenge. This is why there are so many overweight people in our society nowadays.
