Question 1

What macros should I eat to lose weight?

Accepted Answer

For fat loss, set protein high (around 2.2 g per kg body weight) to protect muscle in a calorie deficit, fat at about 0.9 g/kg, and fill the rest with carbs. A 70 kg person on a 1,700 kcal deficit would aim for roughly 154 g protein, 65 g fat, and 130 g carbs. High protein also keeps you full, making the deficit easier to stick to. The calculator above does the maths for you.

Question 2

What are the best macros for muscle gain?

Accepted Answer

To build muscle, eat in a slight calorie surplus (TDEE + ~300 kcal) with protein at 1.6–2.2 g/kg, fat around 1 g/kg, and the rest from carbs — carbs fuel hard training and recovery. A 75 kg lifter might target 150 g protein, 75 g fat, and 350+ g carbs. Pair it with resistance training 3–4× a week so the surplus becomes muscle rather than fat.

Question 3

What is the ideal macro split — 40/30/30 or something else?

Accepted Answer

Fixed percentages like 40/30/30 (carb/protein/fat) are a rough starting point, but setting protein and fat per kg of body weight is more accurate — it scales with your size. The reason: protein needs are tied to lean mass, not total calories. This calculator sets protein (1.8–2.2 g/kg) and fat (0.9–1 g/kg) first, then fills remaining calories with carbs, which adapts to your weight and goal.

Question 4

What macros should a woman eat?

Accepted Answer

Women follow the same per-kg rules as men: protein 1.8–2.2 g/kg, fat ~0.9 g/kg, carbs filling the rest. A 55 kg woman losing fat needs roughly 121 g protein, 50 g fat, and 86 g carbs on a 1,500 kcal target. Protein needs scale with body weight, not gender — women simply weigh less on average. Don't drop fat below 0.8 g/kg, as it supports hormones.

Question 5

Do I have to hit my macros exactly?

Accepted Answer

No — aim to land within about ±5–10 g of each macro per day. Protein is the most important to hit (it drives muscle retention and fullness); carbs and fat can flex around your preferences as long as total calories and protein are roughly on target. This flexible approach is known as IIFYM ("If It Fits Your Macros"). Consistency over a week matters more than perfection on any single day.
