What Macros Are
Macros is short for macronutrients. All food has a certain amount of each macro. The four macros are protein, carbs, fat, and alcohol.
Each macro has a certain amount of calories assigned to it. Calories tell you how much energy you are getting from your food. Macros tell you what that energy is coming from and what that energy will be doing for your body.
Two people can eat the exact same number of calories in a day and end up in very different places. This is why.
Calories Per Gram
Not all macros have the same calorie count per gram.
| Macro | Calories per gram |
|---|---|
| Protein | 4 |
| Carbs | 4 |
| Alcohol | 7 |
| Fat | 9 |
Fat has more than double the calories of protein and carbs for the same weight of food. Alcohol is closer to fat than it is to carbs, which catches most people off guard.
Neither of those is a reason to be afraid of a food. It is a reason to know what you are eating. Two tablespoons of oil in the pan and a full chicken breast have about the same calories, and only one of them shows up on your plate.
Where to Put Your Attention
Protein and carbs are worth real attention. Fat and alcohol only need a number you stay under.
Protein
You set a target and you meet it every day. HIT YOUR PROTEIN. Everything else gets easier once that is handled.
Carbs
Your working energy. They fuel your steps, your training, and your brain. Most people either fear them or eat far too many of them. Carbs are the best lever to pull to improve training quality, especially when timed around workouts.
Fat
Necessary, and you are not cutting it out. You are keeping it modest, because it has more calories per gram than anything else you eat. You just need enough to keep your hormones and vitamin absorption working.
Alcohol
Empty calories. Seven calories per gram, no protein, no fiber, nothing that helps you feel full. It uses up your calories and gives you nothing in return. If you are serious about losing fat, cut it out entirely. Your body treats alcohol as a priority and pushes everything else to the back of the line, so fat burning slows down until the alcohol is cleared.
Protein
Protein is the macro you hit on purpose every day.
Muscle repair and growth
Training breaks muscle down. Protein is what your body uses to rebuild it. In a deficit this matters even more, because the goal is to lose fat while keeping the muscle you already have.
Fullness
Protein keeps you full longer than anything else you can eat. When you have fewer calories to work with, getting more out of every one of them is the difference between a deficit you can hold and one you quit. Your body also works harder to break protein down, which burns more calories through digestion.
Bone density
Protein and resistance training are both linked to better bone density over time. This matters for everyone and it matters more for women, where bone density loss is a known long term concern.
Most beginner advice only talks about muscle repair. Fullness and bone density are why protein stays high whether you are cutting, maintaining, or building.
Carbs
Carbs are the energy you actually run on day to day.
Your body prefers carbs for fuel. Steps, training, work, thinking. Cut them too low and you feel drained, usually before the scale ever reflects anything good.
Not all carbs behave the same. Some digest fast and give you quick energy that fades. Some digest slow, keep you steady, and keep you full much longer. That difference is mostly fiber, and fiber is the reason a plate of potatoes and a candy bar can have the same calories and feel completely different.
Carbs are also where timing starts to matter, specifically around training. Worth understanding, not worth worrying about until the basics are handled.
Fats
You need fat. You are keeping it modest because it has the most calories per gram of any macro.
Fat is not optional. Your body uses it to build hormones, absorb vitamins A, D, E, and K, and keep your cells working. Cut it too low and you get low energy, worse recovery, worse sleep, and for women, problems with your cycle.
At nine calories per gram it is the fastest way to blow past your target without noticing. It hides in cooking oil, dressings, sauces, and cheese. Set your minimum and stay close to it. Every calorie you put toward fat is a calorie you cannot put toward protein or carbs.
Alcohol
Alcohol gives you nothing back.
Alcohol is not technically a macronutrient. Your body has no use for it and cannot build anything out of it. It gets counted here because it has calories, seven per gram, and those calories still land in your day.
None of it does anything for you. No muscle repair, no fuel worth using, no fullness.
The drinks are only part of it. Alcohol makes it much harder to hold your food choices for the rest of the night, and it wrecks your sleep, which leaves you hungrier and more tired the next day.
You do not have to quit drinking forever. You do need to know that a few drinks can wipe out most of a day's deficit. If you drink anyway, do it knowing what it costs you.
How Your Numbers Actually Work
Protein and fat are locked. Carbs are what we change.
Your protein and fat targets get set once and they stay put. Carbs are the number we move when your calories need to go up or down.
| Macro | How it is set | Does it change? |
|---|---|---|
| Protein | Based on your body weight, high enough to hold onto muscle | No |
| Fat | Set at a minimum your body needs to keep hormones and vitamin absorption working | No |
| Carbs | Whatever calories are left after protein and fat are covered | Yes, this is the one we adjust |
| Alcohol | Not part of your targets | Stay away from it |
When we change your calories at a check-in, we are almost always changing your carbs or your steps. Protein stays put because you need it to hold onto muscle. Fat stays put because you need a minimum to keep your hormones and vitamin absorption working. Carbs are the only one with room to move.
What to Do With This
Hit your protein target every day. Fill most of the rest with carbs. Keep fat modest and alcohol occasional.
The ratio matters less than the total. No macro split with a name on it beats hitting your protein and staying under your calorie target. What works is doing the same thing every day, including the days you do not feel like it. You will thank yourself for having meals prepped on those days.
