A diet rich in protein, whole grains and vegetables is ideal for reducing belly fat, as stated by Forbes. Fruits rich in vitamin C, kale, bell pepper, salmon, walnuts and foods rich in omega-3 fatty acids are also instrumental.
Eating whole grains, vegetables and lean proteins keeps people from overindulging in the empty calories that come with processed carbohydrates. Changing such habits as sweetening oatmeal with cinnamon instead of sugar add up over time, according to Forbes.
People who are under stress produce more cortisol, a hormone that tells the body to store belly fat. Vitamin C helps with the management of cortisol production and also helps the body make carnitine, which it uses to turn fat into body fuel. Eating the right fats, including omega-3 fatty acids, leaves people feeling full longer, notes Forbes.
