Cravings Spike as Temperatures Drop: The Science Behind Winter Appetites

On November 15, 2025, research reveals that as the temperature falls, many people's appetites go up. Experts explain that this isn't just due to the holiday season and festive feasting, but rather a result of scientific factors.

Dr. Crystal Wyllie of ZAVA states that when the temperature drops, the body instinctively seeks more energy to maintain its core temperature. This often leads to stronger cravings for calorie-dense comfort foods like mac and cheese, creamy soups, and hot chocolate. Additionally, reduced sunlight triggers dips in serotonin and dopamine, the neurotransmitters that regulate mood, making people more prone to fatigue, irritability, and seasonal affective disorder (SAD). Carbohydrates boost serotonin, which is why people tend to reach for bread, pasta, and chocolate when the days get darker.

To help tackle the hunger pangs and cut calorie intake during the winter months, Dr. Wyllie has come up with seven science-backed ways to suppress appetite and cravings. These include adding spices like chili and ginger, increasing fiber intake, consuming protein-rich breakfasts, and staying hydrated before and during meals.

While prescription weight loss medications like Mounjaro and Wegovy can also help regulate appetite, Dr. Wyllie cautions that these should only be used under the guidance of a healthcare professional, as misuse can lead to significant side effects.
