RH, I did but I had already done that more than a month before I started Keto. Around 10 years ago before I just completely quit trying, I ate high protein, low carb, lifted weights and did cardio for a year. I lost 40 lbs, then gained 10 pounds of muscle back. I was lifting more weight at the end of that year than I was when I was in college and could wear a elliptical out for an hour. Even in that good of shape I felt good but didn’t have much energy. This Keto Diet is responsible for my energy. I don’t know what is doing it or why but I’m not sure at this point that it matters. When I get down to my target weight I’m going to add a few healthy carbs back in limited quantities to see if any of them were causing any problems or if it’s just carbs in general
