My wife and I have used keto and intermittent fasting for over 2 years. We've lost lots of fat and our health has greatly improved. Her and the kids used to be in the doctors office almost weekly it seemed, now no one ever gets sick. These days I drink beer like 3 nights a week and eat whatever I want but 1 meal per day. My weight has stayed constant for the last year and my energy levels are the best they have been since I was a teenager
