When it comes to macronutrients, you’ll be aiming for the following ratios: 60 to 75 percent of your calories should come from fat (but it can be more!). 15 to 30 percent of your calories should come from protein. 5 to 15 percent of your calories should come from carbohydrates. (Most people aim for somewhere between 20 and 55 grams of net carbs daily.)
