It also doesn’t indicate they are worse for you. After 3 months I went from almost prediabetic and bad (not awful, just “take care”levels)of LDL/HDL(ratio) to Ideal ranges and dropped 28lbs. I do believe that keto lifestyle is as valid as the Mediterranean and DASH diets, both of which I tried and failed to stick with, as they were more effort. I’ve been in the ideal range for over a year now (just got retested). So I say go with what works as long as you work with your doctor and get your biomarkers checked. The only exercise I really do is some mild resistance training and 8-10k steps a day, but I was doing that before my weight loss.
