Nutritionist Nmami Agarwal emphasizes the importance of addressing hunger to manage irritability and mood swings. In a recent Instagram video, she explains that the brain primarily relies on glucose for energy. When meals are skipped, blood sugar levels drop, leading to diminished focus and emotional control. This triggers the release of stress hormones, compounding feelings of hunger with stress. Agarwal suggests practical strategies to combat this, such as eating every 3-4 hours, combining carbohydrates with protein and fiber to slow sugar absorption, and incorporating healthy fats for sustained energy. By adopting these habits, individuals can maintain stable energy levels and better manage their moods, reinforcing the idea that a well-fed brain reacts more positively than a hungry one.
