Understanding Results

Total Daily Energy Expenditure (TDEE)

Your TDEE is calculated based on your BMR (Basal Metabolic Rate) and activity level. This determines your daily calorie needs.

Macronutrient Splits

Your macros are calculated as percentages of your total daily calories:

• Protein: 4 calories per gram
• Carbohydrates: 4 calories per gram
• Fats: 9 calories per gram

Recommended Ranges

Protein

• Weight loss: 1.6-2.2g per kg body weight
• Maintenance: 1.4-2.0g per kg body weight
• Muscle gain: 1.8-2.4g per kg body weight

Carbohydrates

• Low-carb: 20-30% of total calories
• Moderate: 40-50% of total calories
• High-carb: 50-60% of total calories

Fats

• Minimum: 20% of total calories
• Balanced: 25-35% of total calories
• Higher-fat: 35-45% of total calories

Frequently Asked Questions

How accurate are the calculations?

The calculator uses well-established formulas based on scientific research, but individual needs may vary. Use these numbers as a starting point and adjust based on your results.

Should I hit my macro targets exactly?

Aim to get within 5-10% of each target. Being slightly over or under occasionally is normal and won’t significantly impact your results.

What foods should I eat to meet my macros?

Focus on:

• Protein: Lean meats, fish, eggs, dairy, legumes
• Carbs: Whole grains, fruits, vegetables, legumes

How often should I recalculate my macros?

Recalculate when your weight changes by more than 10 pounds or if your activity level changes significantly.
