Did Keto as a diabetic and did well with my sugars but didn't lose enough weight, am going to have bariatric surgery next week and then hope to be able to do a lower fat keto type of diet, I have to lose fast as I have 3 hernias and do not want to have plastic mesh to repair them, long story but mesh isn't good for many if not most of us, only way I can get the repairs is to lose nearly 100 pounds and also have issues exercising due to bad knee and torn meniscus.
