Our eating behaviors are extremely subjective, and do not easily respond to change. Someone else's "miracle diet" rarely works for many others; nor is anyone else's workout regimen the right way for anyone else. This, in part, explains the clinical reality that, historically, 90% of people who lose weight based on dietary restrictions tend to gain it back relatively quickly, often putting on more weight than they carried before dieting. (I haven't checked recent research in this area, so my figures may be a bit off, though probably not by much.)
The theory is to at first recognize that either your eating habits and/or your weight are causing distress or ill health, such as fatigue or exhaustion. We can't think or plan or way to weight loss, any more than we can achieve sobriety by using such intellectual tools. We need to take action, often small changes at first, particularly in early sobriety.
Most of us tend to turn the corner when we no longer feel deprived by what we no longer eat (or which we only eat on special occasions), just as when we no longer feel deprived from not drinking (which we should not ever do on special occasions if we wish to remain sober). Exercise is such an important part of weight management, as well as overall health and well-being. Even taking a brisk walk each day can be beneficial. But no one ever lost weight, got sober, or improved their health by sitting on the couch and watching TV or by sitting in front of a computer all day, no matter what those junk emails we all get promise.
