Optimize Your Diet Composition
Calories dictate whether your weight on the scale goes up or down. But Macronutrients (Macros) dictate whether that weight is fat or muscle. Our Macro Calculator takes your calorie goal and divides it into the optimal ratio of proteins, fats, and carbohydrates based on your specific fitness goals.
The Function of the Three Macros
Every diet (Keto, Paleo, Vegan) is simply a manipulation of these three energy sources:
- Protein (4 kcal/gram) The building blocks of muscle. Essential for recovery. When eating in a calorie deficit, high protein intake prevents your body from cannibalizing its own muscle tissue for fuel.
- Dietary Fat (9 kcal/gram) Crucial for hormonal health. Fats are required for your body to produce testosterone and absorb fat-soluble vitamins (A, D, E, K). Never drop fats below 20% of your daily intake.
- Carbohydrates (4 kcal/gram) Your body's preferred, fastest energy source. Carbs fill your muscles with glycogen, allowing you to train harder, lift heavier, and sustain intense cardiovascular exercise.

Frequently Asked Questions
How much protein do I actually need?
For optimal muscle growth (hypertrophy) and preservation during fat loss, science heavily supports consuming 0.8 to 1.0 grams of protein per pound of lean body weight. Eating significantly more than this offers no extra muscle-building benefit.
Do carbs make you fat?
No. Carbs do not uniquely cause fat gain. Only a surplus of total calories causes fat gain. However, carbs do cause your body to retain water (every gram of glycogen stores 3 grams of water), which is why cutting carbs results in rapid, temporary 'water weight' loss on the scale.
What is the Keto macro split?
The Ketogenic diet forces the body to run on fat instead of carbs. The standard Keto macro split is roughly 70% Fat, 25% Protein, and only 5% Carbohydrates (usually under 20g-30g of net carbs per day).
