Cold Temperatures Trigger Increased Appetite, Study Shows

Exposure to cold weather raises the body's energy demand, prompting a physiological response that boosts hunger. A 2023 study published in *Nature* identified specific brain neurons that become active in low temperatures, signaling the need for additional calories. The process of heat production, known as thermogenesis, modestly increases calorie expenditure, reinforcing the appetite signal.

Medical nutrition specialist Dr. Edson Ramuth explains that reduced outdoor activity, heightened consumption of comfort foods, and lower sunlight exposure—which can diminish serotonin production—further intensify cravings for energy‑dense meals such as pasta, sweets, and fatty dishes. He advises focusing on balanced meals rich in protein and fiber, maintaining regular physical activity, and seeking professional guidance to manage nutrition during colder months.
