I have started 16/8 fasting. I have had a few loud tummy growls in the mid morning but I have stayed the course. How long does it take for your body to adjust to start burning fat more efficiently?
Your body will get better at switching into fat-burning mode after a few weeks, especially if you’re eating a low-carb type diet (this is what I have HEARD, I’ve never been low carb for more than a day 😅.) I don’t think you’ll get more efficient at actually burning fat. Exercise in the fasted state helps, too.
