There is a lifestyle change you might be interested in called "intermittent fasting." I have been doing it for a couple months now (I also eat keto) and I have been converting fat to muscle without working out, and I still have my beer at night. Check out Dr. Eric Berg on youtube. I was pretty healthy already, but I am delighted with the changes I have made. I feel better, look better, and smell better. Oh, that would be because I gave up cigarettes lol!
