Diet Macro Adherence Score
Score macro adherence for protein, carbs, and fat with deviation analysis. Enter values for instant results with step-by-step formulas.
Formula
Adherence Score = Average(100 - |Actual - Target| / Target × 200)
Each macro is scored 0-100 based on percentage deviation from target. Scores are averaged for overall adherence. Deviations >50% score 0.
Worked Examples
Example 1: Bodybuilder Cut
Problem:Target: 180g protein, 150g carbs, 50g fat (1730 cal). Actual: 175g protein, 165g carbs, 48g fat.
Solution:Deviations: Protein: |175-180|/180 = 2.8% Carbs: |165-150|/150 = 10% Fat: |48-50|/50 = 4% Calories: 1757 vs 1730 = 1.6% Scores: Protein: 100 - (2.8×2) = 94 Carbs: 100 - (10×2) = 80 Fat: 100 - (4×2) = 92 Calories: 100 - (1.6×2) = 97 Overall: (94+80+92+97)/4 = 90.75 Grade: A (Excellent adherence)
Result:Score: 91/100 (A) | Excellent | Slightly high carbs
Example 2: General Fitness
Problem:Target: 120g protein, 250g carbs, 70g fat (2100 cal). Actual: 95g protein, 280g carbs, 80g fat.
Solution:Deviations: Protein: |95-120|/120 = 20.8% (under by 25g) Carbs: |280-250|/250 = 12% (over by 30g) Fat: |80-70|/70 = 14.3% (over by 10g) Calories: 2215 vs 2100 = 5.5% Scores: Protein: 100 - 41.6 = 58 (LOW - priority fix) Carbs: 100 - 24 = 76 Fat: 100 - 28.6 = 71 Calories: 100 - 11 = 89 Overall: (58+76+71+89)/4 = 73.5 Grade: C (Fair - increase protein)
Result:Score: 74/100 (C) | Undereating protein by 25g
Example 3: Keto Diet
Problem:Keto target: 110g protein, 25g carbs, 165g fat (1995 cal). Actual: 115g protein, 45g carbs, 150g fat.
Solution:Deviations: Protein: |115-110|/110 = 4.5% Carbs: |45-25|/25 = 80% (CRITICAL for keto) Fat: |150-165|/165 = 9.1% Calories: 1945 vs 1995 = 2.5% Scores: Protein: 91 Carbs: 0 (80% deviation = out of ketosis) Fat: 82 Calories: 95 Overall: (91+0+82+95)/4 = 67 Grade: D (Failed keto due to carbs)
Result:Score: 67/100 (D) | 45g carbs exceeds keto limit
Frequently Asked Questions
What are macros in nutrition?
Macronutrients (macros) are nutrients needed in large amounts: Protein (4 cal/g), Carbohydrates (4 cal/g), Fat (9 cal/g). Tracking macros provides more precise nutrition control than just calories.
How do I calculate my macro targets?
Common approach: Protein: 0.7-1g per lb body weight (muscle building: 1-1.2g). Fat: 20-35% of calories. Carbs: remaining calories. Total calories based on goals (deficit, maintenance, surplus).
What's a good macro adherence score?
90%+ = Excellent adherence. 80-89% = Good (within normal variation). 70-79% = Fair (room for improvement). <70% = Poor (significant deviation). Perfect 100% is unrealistic - aim for consistency over perfection.
How flexible can I be with macros?
±10% daily deviation is normal and acceptable. Focus on weekly averages rather than daily perfection. Protein is least flexible (prioritize daily), carbs and fats can balance across days.
Do I need to track macros to lose weight?
No, but it helps. Calorie deficit is requirement for fat loss. Macros optimize body composition (preserve muscle), satiety, performance, and adherence. Many succeed with just calorie/protein tracking.
What are good macro ratios?
Depends on goals: Fat loss: 40% protein, 30% carbs, 30% fat. Muscle gain: 30% protein, 40% carbs, 30% fat. Keto: 5% carbs, 75% fat, 20% protein. Endurance: 15% protein, 60% carbs, 25% fat. Adjust based on response.
How do I track macros accurately?
Use food scale for precision, track everything (including cooking oils, condiments), use databases (USDA, MyFitnessPal), log before eating (enables adjustment), and track consistently (same time, method).
What causes macro tracking to fail?
Common issues: too restrictive (triggers binges), measuring inaccuracy, not tracking 'small' items, weekend inconsistency, dining out challenges, and burnout from excessive tracking. Start flexible, build habits gradually.
Should I cycle macros?
Macro cycling (higher carbs on training days, lower on rest) can optimize performance and recovery. Carb cycling, refeed days, and diet breaks help adherence and metabolism. Advanced strategy - master basics first.
