15. Blueberries
Blueberries are rich in antioxidants, particularly anthocyanins, which support metabolic health by reducing inflammation and improving insulin sensitivity. They are low in calories but high in fiber, meaning they help you feel full while keeping energy levels stable. Blueberries also support brain health and may enhance physical performance. Adding them to yogurt, oatmeal, or smoothies is an easy way to enjoy their metabolism-friendly benefits.
