Fats
Important for vitamin absorption, hormone production, and energy. Found in oils, nuts, avocado, and animal fats.

How we calculate your macros
Example with 2000 daily kcal:
Protein and carbohydrates = 4 cal/g | Fat = 9 cal/g
| Macro | % of Total | Calories | Conversion | Grams |
|---|---|---|---|---|
| Proteins | 30% | 600 kcal | ÷ 4 | 150 g |
| Carbohydrates | 40% | 800 kcal | ÷ 4 | 200 g |
| Fats | 30% | 600 kcal | ÷ 9 | 67 g |
Tips for Better Results
Be Consistent
Consistency is more important than perfection. Maintain your macros for at least 2-3 weeks before adjusting.
Weigh Your Food
Use a kitchen scale for greater accuracy. Visual estimates can have errors of 20-50%.
Use an App
Apps like MyFitnessPal make daily tracking easier. Set your calculated macros here as your goal.
Prioritize Protein
Always hit your protein target first. It's the most important macro for body composition.
