Understanding Calories & Macros
Your body gets calories from 3 main nutrients called macros:
Protein
Fats
Carbohydrates (Carbs)
Each macro provides a certain amount of energy (calories).
Calories Per Macro
Protein = 4 calories per gram
Carbohydrates = 4 calories per gram
Fat = 9 calories per gram
Fat contains more than double the calories per gram compared to protein or carbs, which is why portion balance matters.
Protein: The Foundation
Protein helps support:
Muscle maintenance
Recovery
Metabolism
Hormone function
Feeling full longer
A simple guideline:
Men
Aim for about 1 gram of protein per pound of optimal body weight
Example:
A man whose healthy goal weight is 180 lbs would aim for about:
180g protein daily
Women
Aim for about 0.8 grams of protein per pound of optimal body weight
Example:
A woman whose healthy goal weight is 150 lbs would aim for about:
120g protein daily
This is based on optimal or goal weight — not necessarily current weight.
Fat Intake
Healthy fats are important for:
Hormone production
Brain health
Energy
Skin and hair health
A simple target is:
About 30% of total daily calories from fats
Examples of healthy fats include:
Avocados
Olive oil
Nuts and seeds
Salmon
Eggs
Because fat is calorie-dense, balance is important.
Carbohydrates
After protein and fats are set, the remaining calories usually come from carbohydrates.
Carbs help provide:
Energy
Exercise performance
Brain function
Fiber for digestion
Good carbohydrate sources include:
Fruit
Vegetables
Rice
Potatoes
Oats
Beans
Whole grains
Simple Example
Woman with a goal weight of 150 lbs
Protein
150 × 0.8 = 120g protein
120g protein × 4 calories = 480 calories
Fats
If eating 2,000 calories daily:
30% from fats = 600 calories from fat
600 ÷ 9 = about 67g fat
Carbs
The remaining calories go toward carbohydrates.
2,000 total calories
480 protein calories
600 fat calories
= 920 calories left for carbs
920 ÷ 4 = 230g carbs
The Big Picture
Protein builds and repairs.
Fats support hormones and health.
Carbs fuel energy and performance.
The goal is not perfection — it is balance and consistency over time.
