> since it costs nothing to lose weight, it seems fair. This is only a half truth. Starving yourself is free, but losing weight while still eating a variety of foods (most people can't stomach 24/7 lentils) on extreme financial (including preparation equipment) and time constraints (prep time, time to get ingredients) is nontrivial. Look at the nutritional content of the cheapest and most readily available food you can find (fast food, walmart-brand sausages, etc etc etc). It's typically full of fat and sugars. Higher-quality readily available foods are typically more expensive and harder to come by in poorer areas. Higher-qiality food you prepare yourself is an option, but learning how to do as such is nontrivial and the time investment to prepare these foods can be a major challenge for some.
