Dr. Ashley Lucas explains why eating too little backfires: it slows your metabolism, spikes cortisol and cravings, damages muscle, and wrecks sleep. A small steady calorie deficit works better than aggressive restriction.
Undereating backfires metabolically. Remember that very low intake slows metabolism and increases cravings. You might think, because of what we've been told by the dieting industry, that you just need to continue to eat less and move more. And now there are all these drugs that are allowing us to never be hungry and just eat less and less and less. This is a big issue. It's going to eat away at your muscle, it's going to slow your metabolism. Cortisol rises when you don't consume enough calories, sleep suffers and hunger cues become unpredictable. A small, steady calorie deficit is going to be more effective than aggressive restriction.
