You are totally on the right track, Purbita. What we are witnessing is sort of a culture war between the different diets and their evangelists. Most of them are right for some people, but wrong for others. The inability to recognize this fact has a name–the Dunning-Kruger effect. In five words: low competence begets high confidence. I have written about this in another post. Then, of course, there are those who have the requisite qualification to provide dietary advice, but they are unaware of the principles that govern highly complex systems, such as our human organism, which is hyperastronomically complex. Complexity science 101 should become part of the medical curriculum. After all, we see the bandwidth of interindividually different responses to virtually any type of intervention in every study.
That you have lost weight on a low-carb diet is no surprise. Every gram of sugar your body stores requires another 3 grams of water. You rporbably alos lost some fat tissue, and some muscle mass. So, take care to restrict the loss of the latter.
