If you “bake” your oatmeal right, it can help you lose weight or maintain your healthy weight. This lemon blueberry baked oatmeal recipe does just that! This is because oatmeal has fiber that keeps you satiated throughout the day and promotes a healthy gut. Oatmeal also has other nutrients like magnesium, vitamin B1, and iron.  Adding fresh fruits, dates, and applesauce instead of sugar is another way to avoid weight gain.
