Water
Did you know that you can increase body’s metabolism by 30 percent simply by drinking a big glass of water? Dehydration can also make you feel hungry, so keep drinking water.
Avocados
Perhaps surprisingly, avocados are your fat-burning ally. The monounsaturated fat in avocados boosts metabolism by protecting energy-producing cells from free radical damage. Avocados also help reduce systemic inflammation and prevent blood sugar spikes, which can cause your body to store excess calories as fat.
