Macro tracking for beginners: what protein, carbs, and fat actually do for your training
Macronutrients — protein, carbohydrates, and fat — are the building blocks of your diet. Tracking them helps you eat for your goal instead of guessing. This guide explains what each macro does, how to calculate your targets, and how Budy automates the entire process.

How Budy approaches this need
Here is how macros work, how to calculate yours, and how Budy handles it for you.
What are macros and why do they matter?
Macronutrients are the three categories of nutrients that provide calories: protein (4 cal/g), carbohydrates (4 cal/g), and fat (9 cal/g). Each plays a different role in your body.
Protein builds and repairs muscle tissue — critical for anyone training. Carbohydrates fuel high-intensity exercise and replenish glycogen stores. Fat supports hormone production, brain function, and absorbs fat-soluble vitamins.
Tracking macros means eating specific amounts of each based on your goal. Someone cutting weight needs higher protein to preserve muscle, moderate fat for hormones, and adjusted carbs to maintain the deficit. Someone building muscle needs a caloric surplus with enough protein to support growth.
How Budy automates macro tracking
Budy calculates your BMR using your height, weight, age, and gender. It then estimates your TDEE by factoring in your activity level. From there, it sets a caloric target and macro split based on your goal.
Instead of asking you to weigh food and log every meal, Budy generates daily meal plans with recipes that are pre-calculated to hit your macro targets. The recipes respect your dietary preferences, allergens, and cuisine preferences — the same system that powers the AI meal planner — so you get a meal plan you actually want to follow, not just one that hits the numbers.
