1. What Are Macros?

Macronutrients (macros) are the three main nutrient groups that provide energy: protein, carbohydrates, and fats. Tracking macros helps ensure you're getting the right balance of nutrients for your fitness goals.

2. How Macro Calculation Works

The calculator uses these formulas:

\[ Protein = weight \times 0.8 \, \text{g/lb} \] \[ \text{Remaining Calories} = \text{Total Calories} - (\text{Protein} \times 4) \] \[ \text{Carbs} = \text{Remaining Calories} \times \text{Carb \%} \div 4 \] \[ \text{Fat} = \text{Remaining Calories} \times \text{Fat \%} \div 9 \]

Where:

Protein: 4 calories per gram
Carbs: 4 calories per gram
Fat: 9 calories per gram
Weight: in pounds (lbs)

3. Importance of Proper Macros

Details: Proper macro balance preserves muscle mass while losing fat, maintains energy levels, and supports metabolic health during weight loss.

4. Using the Calculator

Tips: Enter your current weight in pounds and your target daily calorie intake. Select a carb/fat ratio that matches your dietary preferences and energy needs.

5. Frequently Asked Questions (FAQ)

Q1: Why 0.8g protein per pound?
A: This amount helps preserve lean muscle mass during weight loss while being practical for most people to consume.

Q2: Which ratio is best for weight loss?
A: All can work - choose based on personal preference. Low carb may help control hunger, while higher carb may support workout performance.

Q3: Should I adjust these over time?
A: Yes, recalculate whenever your weight changes by 10+ lbs or your activity level changes significantly.

Q4: Are these macros for building muscle?
A: This calculator is for weight loss. Muscle building typically requires higher protein (1g/lb) and more calories.

Q5: How strictly should I follow these numbers?
A: Aim to hit protein and calorie targets consistently. Carbs and fat can vary ±10-20g daily without issue.
