I think you are blaming the wrong people for this. LCHF is the only diet that has helped me lose weight and keep it off. It also helps me control my BGs too. I, and many other people who follow LCHF can only say what works for us. You seem to continually blame us for the fact that people with other alternative diets do not post about them or advise others to follow them. I cannot say to someone that portion control, low GI, low fat worked for me because they didn't. It's for those people who have had success with these diets to come forward and say so.
I have read very many posts where you say you don't like LCHF because you don't like fat and you don't need to lose weight. I for one told you peanuts would be good for you, then you said they had done the trick and helped you put on the weight you wanted to regain and questioned whether people who needed to lose weight should eat nuts!! It just seems to be nit-picking about LCHF all the time.
Honestly, I don't hear you extolling the virtues of any other diet, just saying what you personally hate about LCHF. Please tell others what works for you. Maybe a new thread detailing what you eat and how it works would be good? If you think something isn't being done, then you do it yourself and maybe others will follow.
I am interested in hearing about other diets too.
