People on Wegovy or Ozempic find weight loss plateaus after losing 20-25% of body weight because the body responds by slowing down metabolism, burning fewer calories. Scientists discover in mice that they can turn off a gene so that the body doesn’t realize it is fasting and continues burning sugar.
