I'm 1 week into a 6 week Keto diet structured with 1.5g protein per lb with equal amount of calories from fat. This equlas 375g protein and 167g fat a day from my starting weight of 252lbs. Diet has not been the issue, I do not feel too hungry (someone doesn't feel hungry on a diet isn't really dieting, right?). Nor have I suffered any loss in strength (yet).
My concern is that I am losing weight too fast. I dropped 8lbs of water in the first 48 hours (252 to 244 no concern here as I tend to carry excess water) and have lost an additional 4lbs (240 now) over the next 4 days. My starting BF was around 16-17% and I haven't measured it since I started the diet.
As I understand it my first carb up day should be 2 weeks into the diet, with carbing up once every week thereafter. Should I include a carb up day tomorrow (7 days into the Keto) or not? Also has anyone else experienced weight loss this fast on a keto diet and what were their results with respect to their strength and retaining muscle mass?
