Re: question about these low-carb theories
Carbohydrates and fats are both fuel sources. When the body burns fuel it uses up all the carbs first and then starts on the fat. The problem is that most people overeat on carbs, and therefore rarely burn much fat. Eating lots of carbs is part of most cultures' lifestyles, almost like a craving, which it is very hard to break out of. The proposed solution is to switch to a low- or no-carb diet, thus obtaining most of your body's required daily calories from fat (this is not as unhealthy as it sounds). This way you are less likely to overeat and will have a good chance of some weight loss and fat loss. The downsides of such a diet can include bowel problems due to not enough fibre, kidney problems, and heart disease from eating the wrong fats. In theory, a well-maintained low-carb diet is supposed to be healthier for humans, who have never really evolved to digest carbs well. However, if you try it, ou are advised to stick with it as a permanent lifestyle choice if you want to keep the health benefits (i.e. if you try it for 2 months and then switch back, you will regain any lost weight).
