📝 Fact Check: This is accurate. 🧑🔬 Studies show that when people in a caloric deficit (eating fewer calories than they burn) are sleep-restricted, a much larger percentage of the weight they lose comes from lean muscle mass instead of fat. In one key study, participants on the same diet lost 60% more muscle and 55% less fat when they slept 5.5 hours compared to 8.5 hours. So, even if the scale is going down, your body composition is getting worse.
