At the level of activity most of our clients participate, it is rarely advantageous to increase either carbohydrate or protein intake substantially. Of course, the best way to determine optimal carb and protein intake is to take into account how well you’re losing or maintaining, how you feel, and whether or not you’re able to reach ketosis during Weight Loss.
Serious weight lifters usually eat about 1.5 to 2 grams of protein per kg (that’s 2.2 lbs.) of their body weight per day. But keep in mind that that’s with high intensity, often very aerobic, weight training. They find that they need such high protein intake to maximize muscle growth during these periods. Similarly, aerobic exercisers will increase carbs during times of prolonged, high intensity training (see the FAQ on carbo loading for more info).
