Cutting out carbs from your diet is one of the quickest way to lose weight fast. When you stop eating simple carbs like white bread and white pasta, your body turns into a fat burning machine. Your metabolism will speed up dramatically if you eat more lean protein and cut out the carbs. Replace all carbs you eat with vegetables, and some fruit, but not too much fruit since it is generally high in sugar. Other things that are good to eat are nuts like almonds or walnuts, and lentils like beans. Changing up your diet is one of the best ways to produce huge weight loss results.
