My Metabolism 100% shut down along with my thyroid a few years ago. The last 15 months, I have been in the gym 6 days a week, ate clean and put on a ton of muscle and still no fat loss.
After a ton of blood work and medical tests, it turned out to be a medical thing preventing my metabolism from functioning. In the end, I had RNY Gastric Bypass last month and will be returning to the gym next week for cardio and weight training 2 weeks after that. To preserve my muscle that I built during rapid weight loss, Im taking BCAA's with L-Glutamine every day.
At the beginning, I will be working on more of a cut routine, since Im not able to even take in 1,000 calories a day for at least another 9-12 months.
