You are trying to lose weight and, actually, you were doing just fine until recently. You were eating better and working out, and all of the sudden what had been working for you, stopped. It doesn’t quite make sense, does it?
Weight loss plateaus are frustrating because they seem to come out of nowhere. Scientists commonly refer to a weight loss plateau as adaptive thermogenesis. The cause of adaptive thermogenesis is not known, but researchers believe that it can be caused by changes in body weight, thyroid function or changes in leptin levels or sensitivity. Leptin is a hormone released from fat cells that acts on your brain and regulates appetite and body weight.
