Aaron Hartman, MD warns that healthy weight loss is about 1–2 pounds per week (4–8 pounds per month) and that very rapid loss (for example, ~20 pounds in a month) leads to loss of muscle mass. He describes the phenomenon called 'ozempic face,' where rapid fat and muscle loss — including in the cheeks and face — can create a hollowed appearance.
