Читать книгу The Renaissance Diet 2.0 - Mike Israetel, James Hoffmann - Страница 39

Calories and macronutrients are not independent variables in nutrition. Calories, as described in the last chapter, are units of energy. All the macronutrients supply energy and, therefore, contain calories. The per gram calorie content of each macro is:

•Protein: 4 calories per gram

•Carbohydrate: 4 calories per gram

•Fat: 9 calories per gram

As you can see, while both protein and carbohydrate carry only 4 calories per gram of macronutrient, fats have more than double, with 9 calories per gram of fat. This information will play a role in your diet construction and in how you allocate amounts of macronutrients to fit within your calorie constraints.
