What is a Macro Target?

The three macronutrients — protein, carbohydrates, and fat — each serve different functions in the body and contain different amounts of energy per gram. Protein supports muscle repair and satiety (4 kcal/g). Carbohydrates are the primary energy source (4 kcal/g). Fat supports hormone function and fat-soluble vitamin absorption (9 kcal/g).

A macro target gives you a daily gram goal for each of the three. Rather than telling you what to eat meal by meal, it sets the framework within which you make your own food choices. Hitting a protein target of 160g, for example, means you need to include adequate protein sources across your meals — but which sources, and how you combine them, is up to you.

Macro targets are typically set based on bodyweight, body composition goals, and activity level. For muscle gain, protein targets are usually higher (1.6–2.2g per kg of bodyweight is commonly cited in sports nutrition literature). For weight loss, the key variable is a calorie deficit, with protein targets kept high to preserve muscle mass. Fat and carbohydrate targets fill in the remaining calories according to personal preference and performance needs.

The main difference between macro tracking and simple calorie counting is granularity. Calorie counting answers "how much energy am I consuming?" Macro tracking additionally answers "what is that energy made of?" For people focused on body composition rather than just weight, this distinction matters — you can lose weight eating 2,000 calories of mostly fat and carbs, but you're unlikely to gain muscle without adequate protein.

Coaches using CalCoach can set macro targets for each client directly from their dashboard, and clients see their progress against those targets in real time as they log food through the day.
