What Are Macros?
Macros is short for macronutrients. There are three main types of macros:
- Carbohydrates: These are sugars and starches.
- Proteins: These help build and repair your body.
- Fats: These provide energy and support cell health.
On a keto diet, you will eat fewer carbs and more fats. This helps your body enter a state called ketosis.
Why Calculate Your Macros?
Calculating your macros helps you:
- Stay on track with your diet.
- Understand what you eat.
- Reach your weight loss goals.
How to Calculate Your Macros for a Keto Diet
Follow these simple steps to calculate your macros:
Step 1: Determine Your Daily Caloric Needs
First, you need to know how many calories you should eat. You can use the following formula:
| Activity Level | Multiplier |
|---|---|
| Sedentary (little exercise) | 1.2 |
| Lightly active (light exercise 1-3 days a week) | 1.375 |
| Moderately active (moderate exercise 3-5 days a week) | 1.55 |
| Very active (hard exercise 6-7 days a week) | 1.725 |
| Extra active (very hard exercise, physical job) | 1.9 |
To find your calorie needs:
- Find your Basal Metabolic Rate (BMR) using this formula:
BMR for Men: 66 + (6.23 x weight in lbs) + (12.7 x height in inches) – (6.8 x age in years)
BMR for Women: 655 + (4.35 x weight in lbs) + (4.7 x height in inches) – (4.7 x age in years)
Then multiply your BMR by your activity level. This gives you your daily caloric needs.
Step 2: Set Your Macro Ratios
For a keto diet, the macro ratios are usually:
- Fat: 70-75%
- Protein: 20-25%
- Carbohydrates: 5-10%
You can choose what works best for you. Most people follow a 70-25-5 ratio.
Step 3: Calculate Your Macros
Now, let’s calculate your macros using your daily caloric needs. Here’s how:
- Convert your percentages into decimals:
- Fat: 0.70
- Protein: 0.25
- Carbohydrates: 0.05
- Multiply your daily calorie needs by these decimals:
- Calories from Fat = Daily Calories x 0.70
- Calories from Protein = Daily Calories x 0.25
- Calories from Carbohydrates = Daily Calories x 0.05
Next, convert these calories into grams:
- Fat: 1 gram = 9 calories
- Protein: 1 gram = 4 calories
- Carbohydrates: 1 gram = 4 calories
To find grams:
- Grams of Fat = Calories from Fat ÷ 9
- Grams of Protein = Calories from Protein ÷ 4
- Grams of Carbohydrates = Calories from Carbs ÷ 4
Example Calculation
Let’s say you are a woman. You weigh 150 lbs, are 5’5″ tall, and are 30 years old. You exercise lightly.
First, calculate your BMR:
BMR = 655 + (4.35 x 150) + (4.7 x 65) – (4.7 x 30) = 1,453 calories
Now multiply by your activity level:
1,453 x 1.375 = 1,996 calories per day.
Now set your macros:
- Fat: 1,996 x 0.70 = 1,397 calories
- Protein: 1,996 x 0.25 = 499 calories
- Carbs: 1,996 x 0.05 = 100 calories
Convert to grams:
- Fat: 1,397 ÷ 9 = 155 grams
- Protein: 499 ÷ 4 = 125 grams
- Carbs: 100 ÷ 4 = 25 grams
Your final macros would be:
- Fat: 155 grams
- Protein: 125 grams
- Carbohydrates: 25 grams
