Hi I'm looking for some advice on how much protein, fat and carbs I need to maintain weight and gain muscle. My weight is 149lb, I am 5 feet 7 inches, my body fat is 18%. If someone can give me an estimate of how many grams of protein, fat, carbs I need, that would be really helpful. I have used other online macro calculators, but would like to see your answers on the matter. Thank you!
