I did gain weight but had been slowly gaining over several years after an injury. I know I could work it all back off in about 6 months but my wife and I decided to try keto. Believe it or not keto works. It’s kinda gross eating high fats though. I swear that’s part of this diet, to get you disgusted with the idea of eating fatty foods. I’m going on 3 weeks and I don’t want to see another piece of cheese or an egg for a couple of years.
