i lost weight faster than eating nothing which is what i normally have to do because even if i eat 400 calories of healthy food i won't lose weight. haven't done a hair test but i will eventually.
I am not in favor of trying to eat less for loosing weight, but not either in favor of trying to eat more, as I do not believe that metabolism will make the fat melt! In most cases metbolism needs more thing in order to change. I have no idea why eating fat only helped you loose weight, as ketosis seems to demand a bit more time than 4 days...
I answer you here because i do not want to derail the keto topic...
i def have adrenal issues!
Deal with this 1st would seem reasonable according to my readings of tpauk.... And the hair test is not that expensive compared to the benefits of knowing more about your case, especially to take supps and even the cream of tartar you spoke about, or try to use licorice root, which I saw they use only in short cycles, not of regular use.
What I can suggest, as you seem to eat low calories: Stay with what you do now but add vegetable juices for the minerals, and enzyme of the raw food. My concern is not about calories but low minerals. I would also use a little green salad before all meals, with EVOO and ACV. Even if you want to do it only for lunch and dinner and not for breakfast! The bitter taste in the mouth triggers stomach juices.
What is your global eating style?
