Walnuts

Walnuts are superfoods which can increase your overall weight. A 100gms serving of walnuts offer 587 calories, along with 65gms of fat and 14gms carbohydrates. They are rich in omega-fatty acids which contribute to weight gain when consumed in slightly higher quantities. Additionally, walnuts are a storehouse of many important minerals like magnesium, iron, along with dietary fiber, making them ideal dry fruits for gaining weight. You can have them as whole nuts or add them to baked goods.
