Understanding Macronutrients
Macronutrients (Carbohydrates, Proteins, and Fats) make up the bulk of your calorie intake. Carbohydrates and proteins provide 4 calories per gram, while fats provide 9 calories per gram. Adjusting the ratio is key to meeting body composition goals.
Mathematical Formula
\text{Grams} = \frac{\text{Calorie Target} \times \text{Macro Percentage}}{\text{Calories per Gram}}
Formula Explanation:
- Carbohydrates: 4 kcal per gram
- Proteins: 4 kcal per gram
- Fats: 9 kcal per gram
- Standard balanced diet recommendation: 50% carbs, 20% protein, 30% fat.
Terms & Abbreviations
Macros Macronutrients - energy-yielding nutrients required in large amounts.
Keto Ketogenic diet - extremely low-carbohydrate, high-fat split.
Kcal Kilocalories - the standard unit of dietary energy.
Frequently Asked Questions
Fats are structurally denser and contain more carbon-hydrogen bonds, providing 9 calories of energy per gram compared to the 4 calories in carbohydrates and proteins.
A ketogenic split forces the body to burn fat for fuel by reducing carbs to around 5% of total calories and increasing fat to 70%, inducing ketosis.
