1. What is IIFYM Macro Calculation?

IIFYM (If It Fits Your Macros) is a flexible dieting approach that focuses on meeting specific macronutrient targets rather than restricting certain foods. This calculator helps determine your optimal protein, fat, and carbohydrate intake based on your TDEE and calorie deficit goals.

2. How Does the Calculator Work?

The calculator uses the IIFYM formula with standard ratios:

\[ \text{Protein (g)} = \frac{\text{Calories} \times 0.3}{4} \] \[ \text{Fat (g)} = \frac{\text{Calories} \times 0.3}{9} \] \[ \text{Carbs (g)} = \frac{\text{Calories} \times 0.4}{4} \]

Where:

\( \text{Calories} \) — TDEE minus deficit (kcal)
\( 0.3 \) — 30% of calories from protein
\( 0.3 \) — 30% of calories from fat
\( 0.4 \) — 40% of calories from carbs
\( 4 \) — Calories per gram of protein/carbs
\( 9 \) — Calories per gram of fat

Explanation: The formula converts calorie percentages into gram amounts using the energy density of each macronutrient.

3. Importance of Macro Tracking

Details: Tracking macros helps ensure proper nutrient distribution, supports muscle maintenance/growth, and provides flexibility in food choices while meeting nutritional goals.

4. Using the Calculator

Tips: Enter your Total Daily Energy Expenditure (TDEE) and desired calorie deficit. Both values must be positive numbers, with deficit not exceeding TDEE.

5. Frequently Asked Questions (FAQ)

Q1: What are the standard IIFYM ratios?
A: The standard distribution is 30% protein, 30% fat, and 40% carbohydrates, but these can be adjusted based on individual preferences and goals.

Q2: How do I calculate my TDEE?
A: TDEE can be estimated using online calculators that consider your age, weight, height, gender, and activity level.

Q3: Can I adjust the macro ratios?
A: Yes, the ratios can be customized based on your specific dietary needs, training goals, or medical requirements.

Q4: Is IIFYM suitable for everyone?
A: While flexible, IIFYM may not be ideal for those with specific medical conditions or who prefer more structured eating patterns.

Q5: How often should I recalculate my macros?
A: Recalculate when your weight changes significantly, your activity level changes, or every 4-6 weeks to account for metabolic adaptations.
