Frequently Asked Questions
How many calories are in a gram of fat?
Fat is very calorie-dense. There are 9 calories in every gram of fat, whereas there are only 4 calories in a gram of protein or carbohydrates.
Which macro split should I choose?
If your goal is building muscle, ensure protein is high (30%+). If your goal is endurance sports, keep carbs high (50%+). If you want standard health maintenance, a balanced 30/35/35 split is ideal.
