14. Avocado
Avocados provide healthy monounsaturated fats that can support metabolism by improving nutrient absorption and energy regulation. They’re also high in fiber, which slows digestion and keeps blood sugar steady. Despite being calorie-dense, avocados encourage satiety and may reduce overeating. Their unique combination of fat, fiber, and micronutrients makes them an excellent food for keeping metabolism balanced while adding creaminess to meals.
