For a healthy diet on dual-metabolising you should make more combinations between fats, proteins, carbs and dairy products. Making sure you eat a correct balance is importantFast-metabolismIf you feel athletic or energetic after eating a large protein based meal's, it's likely you fall into the Fast-metabolising category.
