This post gives me hope for my own situation.^^^ This is the best advice you can get when starting a Ray Peat inspired nutrition.
I like many others experienced a lot of weight gain(fat and water, used to be super shredded) first 7-8 months even though I had 3,500-4,000+ calorie diet prior. Was 12-13 years ultra strict keto/carni and my body just didn't know how to respond to carbs and ballooned up. And I had no thyroid issues with TSH below 1 and hormones all in optimal range. Essentially I was doing Keto + carbs for the first few months because I could not let go of fats and it was a disaster :-D
Best to limit fats for awhile, later on you can add more and more until feeling optimal. Now I am back to my old body but feeling less tense/stressed due to chronically lower cortisol/adrenaline. Best switch ever, thanks Ray !
