📈 Calorie Targets — All Goals Compared
What Are Macros and Why Do They Matter?
Macronutrients (macros) are the three main nutrient classes that provide energy: protein, carbohydrates, and fat. Each plays a unique role in body composition, performance, and health. Unlike calorie counting alone, tracking macros lets you optimize what those calories are made of — not just how many there are. Start with a full daily number from our calorie calculator, or TDEE calculator if you just need maintenance calories, then use this tool to split that number into grams.
How Macros Are Calculated
Step 1 — BMR (Mifflin-St Jeor): Male = 10W + 6.25H − 5A + 5 · Female = 10W + 6.25H − 5A − 161Step 2 — TDEE = BMR × Activity Factor (1.2 – 1.9)Step 3 — Calorie Target = TDEE + Goal Adjustment (−750 to +500 kcal)Step 4 — Macro Split (Standard): Protein 30% of calories ÷ 4 = grams · Carbs 40% ÷ 4 = grams · Fat 30% ÷ 9 = gramsW = weight in kg, H = height in cm, A = age in years. Protein and carbs supply 4 kcal per gram; fat supplies 9 kcal per gram — which is why the same percentage of calories produces far fewer grams of fat than protein or carbs.
Choosing Your Macro Split
🍗
High Protein (40/35/25)
Best for muscle building and fat loss. Protein preserves lean mass in a deficit and supports muscle protein synthesis in a surplus.
🥑
Ketogenic (30/5/65)
Very low carb, high fat, forcing the body onto fat and ketones for fuel. Effective for fat loss but restrictive and requires an adaptation period.
🥗
Standard (30/40/30)
Balanced macro ratio suitable for most adults maintaining weight or building muscle with steady, adequate carbohydrate for training.
🍞
Endurance (25/55/20)
Higher-carbohydrate fuel sustained aerobic exercise. Used by distance runners, cyclists, and triathletes during heavy training blocks.
