Short answer
Set protein first at roughly 0.7–1g per pound of target body weight, set fat at about 25–35% of calories, and fill the remainder with carbohydrate. Protein is the target worth hitting precisely.
Macros are the three things that carry calories: protein (4 cal/g), carbohydrate (4 cal/g) and fat (9 cal/g). Calories tell you how much energy; macros tell you what it is made of, and that changes body composition, hunger and training.
Setting your targets
- Start from calories. Macros have to add up to your calorie target, so set that first.
- Protein first. Roughly 0.7–1g per pound of target body weight. This is the one that protects muscle in a deficit and keeps you full.
- Fat next. About 25–35% of total calories. Going much lower is unpleasant and unnecessary.
- Carbs get the rest. They are the flexible one — fuel for training and, for most people, the easiest lever to move.
Tracking without it eating your life
- Log before you eat, not after. Easier to adjust a meal than regret it.
- Build a rotation. Most people eat the same 20 or so meals. Log them once and reuse.
- Weigh the calorie-dense things. Oil, nut butter, cheese, nuts. Vegetables can be eyeballed; olive oil cannot.
- Aim for close, not exact. Within 5–10g on protein and calories is plenty. Precision beyond that buys nothing.
How long should you track?
Long enough to calibrate your eye — usually four to eight weeks. Most people find that after a couple of months they can estimate well without logging every meal, and only return to tracking when they want to change something.
Tracking is a measuring tool, not a permanent lifestyle. If it starts feeling compulsive rather than useful, that is a good reason to stop and talk to someone.
