1. What is the AMDR Range?

The Acceptable Macronutrient Distribution Range (AMDR) is the range of intake for a particular energy source (carbohydrates, fats, proteins) that is associated with reduced risk of chronic disease while providing adequate intakes of essential nutrients.

2. How Does the Calculator Work?

The calculator uses the AMDR range formula:

Where:

• \( min\% \) — Minimum percentage of calories
• \( max\% \) — Maximum percentage of calories
• \( calories \) — Total daily calorie intake
• \( macro\_cal\_per\_g \) — Calories per gram of the macronutrient

Explanation: The equation converts percentage ranges of total calories into gram amounts based on the calorie density of each macronutrient.

3. Importance of AMDR Calculation

Details: Calculating AMDR ranges helps ensure balanced nutrition by providing appropriate proportions of carbohydrates (45-65%), fats (20-35%), and proteins (10-35%) in the diet.

4. Using the Calculator

Tips: Enter your total daily calories, the recommended percentage range for the macronutrient, and the calories per gram (4 for carbs/protein, 9 for fats). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are standard AMDR percentages?
A: For adults: Carbs 45-65%, Fats 20-35%, Protein 10-35%. These may vary for specific populations.

Q2: What are the calorie values per gram?
A: Carbohydrates: 4 kcal/g, Protein: 4 kcal/g, Fats: 9 kcal/g, Alcohol: 7 kcal/g.

Q3: Should everyone use the same ranges?
A: No, ranges should be adjusted based on individual health goals, activity levels, and medical conditions.

Q4: How precise should I be with these ranges?
A: These are general guidelines. Small deviations are acceptable unless you have specific medical requirements.

Q5: Can I use this for weight loss?
A: Yes, but total calorie intake is more important than macronutrient distribution for weight loss.
