Hyperthyroidism
If you’re eating more than usual and you’re also dropping pounds, your thyroid could be overproducing hormones, triggering your body to kick things up. “Think of the thyroid as an endocrine hormonal organ that speeds everything in the body up,” says Dr. Lofton. “So you would also speed up metabolically and increase their hunger as a result.”
The thyroid is also involved in satiety, so you might find your cravings harder to satisfy if it’s overactive, says Dr. Levine. See if your hunger is paired with fatigue, moodiness, brittle nails, or hair loss—they’re all signs of hyperthyroidism.
