We are an endocrinologist, a woman who lost 140 pounds and became a personal trainer, and a primary care internist. Ask Us Anything.

Although it’s true your tdee decreases as you lose weight and you may plateau if you don’t adjust your intake, I think their specific question was about starvation mode, which would be good to note generally can be traced back to the Minnesota starvation experiments in the 40s.

The idea of starvation mode in the sense people like to frame it (I’ll gain weight if I skip a meal) is nothing like what the experiment found where people stopped losing weight because they had no weight to lose. They noted their metabolism did indeed slow at this point, you also saw effects like their temperature dropping, and it was seen at the end of a pretty extreme experiment, and not anything anybody would come close to mimicking with what we consider normal dieting.
