Counting calories gets you halfway to your goals. Counting macros – protein, carbohydrates, and fat – gets you the rest of the way, because where your calories come from affects hunger, muscle retention, and how sustainable your diet feels.
Start With Your Calorie Target
Before you can split calories into macros, you need a daily calorie target based on your Total Daily Energy Expenditure (TDEE) and your goal. For weight loss, a deficit of roughly 300-500 calories below TDEE is a reasonable starting point.
Prioritize Protein First
Protein is the macro to set first, not last. It preserves lean muscle during a calorie deficit and keeps you fuller for longer. A common target is around 0.7-1 gram of protein per pound of body weight, adjusted based on activity level and how much muscle you’re carrying.
Balance Fat and Carbohydrates
Fat supports hormone production and shouldn’t drop too low – most people do well keeping fat around 20-30% of total calories. Whatever calories remain after protein and fat are allocated go to carbohydrates, which fuel workouts and daily activity.
Adjust Based on Results
Macros aren’t set-and-forget. Track your progress for two to three weeks, then adjust based on how your weight, energy, and hunger levels respond. Small, consistent tweaks work better than large swings.
