6. Apple Cider Vinegar
Apple cider vinegar has been linked to improved digestion and better blood sugar control, both of which can support a more efficient metabolism. The acetic acid in vinegar may increase feelings of fullness, helping reduce overall calorie intake. While it isn’t a miracle solution, a tablespoon diluted in water before meals can gently assist your metabolism. It’s also a versatile ingredient for dressings and marinades.
