Appendices
This content is for informational purposes only and does not constitute medical or nutritional advice. Speak with your health professional before starting this protocol.
Appendix disclaimer: Sample meal plans and worked calculations in these appendices are illustrative examples based on representative body compositions. Do not follow these plans directly — use your own calculated targets from the sprint setup process. Individual protein, fat, and calorie targets will differ.
Appendix A: Sample Meal Plans
A1. Male, 100 kg, 28% body fat (Sprint Level 3)
Sample stats: 100 kg total weight, 28% body fat, LBM 72 kg. Protein target: 158 g (2.2 g/kg LBM). Fat: 25 g/day. Sprint Level 3.
Note: The 800 kcal figure is the floor — the minimum, not the target. For a 90–110 kg male, the macro calculation typically produces 950–1,150 kcal per day. These plans reflect realistic targets driven by protein and fat requirements. No artificial protein top-ups are needed at this body weight.
Day 1
| Meal | Food | Protein (g) | Calories |
|---|---|---|---|
| Breakfast | 250 g egg whites + 1 whole egg, scrambled with 200 g spinach | 39 | 248 |
| Lunch | 200 g chicken breast (grilled) + 250 g mixed salad (vinegar dressing) + 150 g steamed broccoli | 70 | 431 |
| Dinner | 150 g cod + 300 g broccoli (steamed) | 43 | 260 |
| Snack | 150 g nonfat Greek yogurt + 200 g cucumber + 100 g bell pepper | 17 | 150 |
| Fish oil + supplements | 10 ml fish oil, multivitamin, electrolytes | 0 | 100 |
| Totals | 169 | 1,189 |
Day 2
| Meal | Food | Protein (g) | Calories |
|---|---|---|---|
| Breakfast | 150 g egg whites + 2 whole eggs, scrambled with 150 g spinach | 33 | 255 |

| Dinner | 200 g shrimp (steamed) + 300 g zucchini noodles + 150 g bok choy (steamed) + 150 g cherry tomatoes | 55 | 296 |
| Snack | 200 g nonfat Greek yogurt + 150 g cucumber | 21 | 141 |
| Fish oil + supplements | 10 ml fish oil, multivitamin, electrolytes | 0 | 100 |
| Totals | 184 | 1,170 |
Day 3
| Meal | Food | Protein (g) | Calories |
|---|---|---|---|
| Breakfast | 2 scoops whey protein (60 g powder) + 200 g spinach + water + ice | 53 | 281 |
| Lunch | 200 g lean beef (95% lean) + 200 g green beans + 150 g steamed broccoli | 60 | 421 |
| Dinner | 150 g chicken breast + 200 g cauliflower rice + 150 g steamed kale + 150 g cherry tomatoes | 57 | 377 |
| Snack | 150 g nonfat Greek yogurt | 15 | 89 |
| Fish oil + supplements | 10 ml fish oil, multivitamin, electrolytes | 0 | 100 |
| Totals | 185 | 1,268 |
A2. Female, 75 kg, 30% body fat (Sprint Level 2)
Sample stats: 75 kg total weight, 30% body fat, LBM 52.5 kg. Protein target: 129 g (2.45 g/kg LBM). Fat: 27 g/day (Level 2). Sprint Level 2.
Note: For a 65–85 kg female, the derived calorie target is typically 800–950 kcal/day depending on body composition and Sprint Level. Day 1 lands above the floor naturally from correct protein and fat targets. Day 2 uses slightly larger portions on two items to clear the 800 kcal floor — no separate protein top-up row needed.
Day 1
| Meal | Food | Protein (g) | Calories |
|---|---|---|---|
| Breakfast | 150 g egg whites + 1 whole egg, scrambled with 150 g spinach | 27 | 183 |

| Fish oil + supplements | 10 ml fish oil, multivitamin, electrolytes | 0 | 95 |
| Totals | 145 | 986 |
A3. Refeed Day Meal Plan
Example: 80 kg male at estimated 2,200 kcal maintenance.
Note: On refeed days, fat remains the same as regular sprint days — it does not increase. Carbohydrates are added; fat stays fixed. This example uses Level 2 fat (27 g/day). High-fat foods such as salmon or dark chocolate are not appropriate on refeed days.
| Meal | Food | Protein (g) | Carbs (g) | Fat (g) | Calories |
|---|---|---|---|---|---|
| Breakfast | 100 g oats + 1 banana + 1 scoop whey + 200 ml skim milk | 35 | 85 | 8 | 530 |

| Totals | 148 | 352 | 27 | 2,220 |
Appendix B: Macro Calculation Worksheets
B1. Fat Loss Sprint Macro Calculator
Step 1: Determine your Lean Body Mass (LBM)
LBM = Total body weight × (1 − body fat fraction)
Example: 90 kg at 30% body fat → LBM = 90 × 0.70 = 63 kg
My body weight: _______ kg. My body fat %: _______ %. My LBM: _______ kg.
Step 2: Calculate your protein target
Protein is calculated from lean body mass using a sliding scale based on body fat percentage. The app calculates this automatically — enter your stats and the app outputs your protein target.
- Sprint Level 1 (low body fat): up to 3.0 g/kg LBM
- Sprint Level 2 (moderate body fat): approximately 2.35–2.7 g/kg LBM
- Sprint Level 3 (high body fat): 2.2 g/kg LBM
Minimum: 2.2 g/kg LBM. Maximum: 3.0 g/kg LBM.
My protein target: _______ kg LBM × _______ g/kg = _______ g protein/day
Step 3: Calculate protein calories
Protein calories = protein grams × 4
My protein calories: _______ g × 4 = _______ kcal from protein
Step 4: Add supplemental fat
Fat allowance is fixed by Sprint Level:
- Sprint Level 1: 30 g/day = 270 kcal
- Sprint Level 2: 27 g/day = 243 kcal
- Sprint Level 3: 25 g/day = 225 kcal
My fat allowance: _______ g = _______ kcal from fat
Step 5: Add vegetable carbohydrates
Non-starchy vegetables: eat freely. Count net carbs only (total carbs minus fibre). Target is 50 g net per day; cruciferous and leafy vegetables are mostly fibre, so generous portions still land inside that window. The app allows up to ~70 g before flagging over so a veg-heavy day stays in range. Use ~50 g net carbs / 200 kcal as your working estimate.
My carb calories: approximately _______ kcal from vegetables
Step 6: Total daily calories
Total = protein calories + fat calories + carb calories
My daily total: _______ + _______ + _______ = _______ kcal/day
B2. Maintenance Calorie Calculator (Post-Sprint)
Step 1: Calculate BMR (Mifflin-St Jeor)
- Men: BMR = (10 × weight in kg) + (6.25 × height in cm) – (5 × age) + 5
- Women: BMR = (10 × weight in kg) + (6.25 × height in cm) – (5 × age) – 161
My BMR: (10 × _____) + (6.25 × _____) – (5 × _____) +/– _____ = _______ kcal
Step 2: Apply activity multiplier
| Activity Level | Multiplier | Description |
|---|---|---|
| Sedentary | × 1.2 | Little or no exercise, desk job |
| Lightly active | × 1.375 | Light exercise 1–3 days/week |
| Moderately active | × 1.55 | Moderate exercise 3–5 days/week |
| Very active | × 1.725 | Hard exercise 6–7 days/week |
| Extremely Active | × 1.9 | Intense daily training (HIIT, running, 5–6 strength sessions/week) or physically demanding job |
My predicted TDEE: _______ × _______ = _______ kcal
Step 3: Apply metabolic adaptation discount (7–8%)
My adjusted maintenance: _______ × 0.92 = _______ kcal/day
Step 4: Set maintenance macros
- Protein: 2.0 g/kg LBM = _______ g/day (_______ kcal)
- Fat (27.5% of TDEE): _______ kcal × 0.275 ÷ 9 = _______ g/day
- Carbohydrates (remainder): (_______ kcal − protein kcal − fat kcal) ÷ 4 = _______ g/day

Appendix I: FLS Calculation Reference
All v2 protocol calculations in one place. Use this to set up your sprint, plan refeeds, manage your diet break, and verify your numbers.
I1. Sprint Level Determination
Step 1: Measure your body fat percentage
| Your Profile | Recommended Method |
|---|---|
| Athlete or above-average muscle mass | DEXA, then skinfold, then medical BIA, then visual (in order of preference) |
| General population, non-athlete | US Navy Circumference Method |
Navy Method formulas (all measurements in cm):
Men: BF% = 86.010 × log10(waist − neck) − 70.041 × log10(height) + 36.76
Women: BF% = 163.205 × log10(waist + hip − neck) − 97.684 × log10(height) − 78.387
Step 2: Assign your Sprint Level
| Sprint Level | Male BF% | Female BF% |
|---|---|---|
| Level 1 — Lean | Below 16% | Below 25% |
| Level 2 — Moderate | 16–25% | 25–35% |
| Level 3 — Overweight | Above 25% | Above 35% |
Eligibility (all must pass):
| Parameter | Minimum | Maximum |
|---|---|---|
| Age | 18 years | 100 years |
| Body weight | 55 kg | No maximum |
| Body fat % (all) | 5% | 50% |
| Body fat % — males | 12% | N/A |
| Body fat % — females | 18% | N/A |
My Sprint Level: ______ My LBM: ______ kg
I2. Protein Calculation Worksheet
Protein target is determined by body fat percentage using a sliding scale within each sprint level. No activity adjustment applies during the FLS — protein is fixed by BF% position within the level.
Sliding scale logic:
- At the lean boundary of each level (lower BF%): higher protein, up to 3.0 g/kg LBM
- At the overweight boundary (higher BF%): lower protein, down to 2.2 g/kg LBM
- Interpolate linearly within each level
Formula: g/kg LBM = 2.2 + [(BF% range upper − your BF%) ÷ (BF% range)] × 0.8
Clamp: If result falls below 2.2 g/kg LBM, use 2.2. If above 3.0 g/kg LBM, use 3.0.
Worked examples:
| Profile | LBM | BF% | g/kg LBM | Total Protein |
|---|---|---|---|---|
| Male, Level 3 (at or above 25% BF) | 65 kg | 28% | 2.2 (floor) | 143 g |
| Female, Level 2 (25–35% range) | 51 kg | 32% | 2.35 | 120 g |
| Male, Level 1 (below 16% BF) | 70 kg | 12% | 3.0 (ceiling) | 210 g |
| Male, Level 2 (16–25% range) | 66.3 kg | 22% | 2.37 | 157 g |
My protein calculation:
- My body fat %: ______ %
- My sprint level: ______
- g/kg LBM from sliding scale: ______
- × My LBM (______ kg)
- My protein target: ______ g/day
I3. Activity Level Self-Assessment
Use for TDEE calculation during the diet break and post-sprint maintenance. Protein during the FLS has no activity adjustment.
| Activity Level | TDEE Multiplier | Description | Gym | Cardio | Daily Steps |
|---|---|---|---|---|---|
| Sedentary | 1.2 | Little to no structured exercise, mostly sitting | 0 sessions | 0 hrs | Below 5,000 |
| Lightly Active | 1.375 | Occasional workouts, limited daily movement | ~3/week | 1 hr or less/week | Below 5,000 |
| Moderately Active | 1.55 | Regular strength training, moderate daily movement | 3+/week | 1–2 hrs/week | 5,000–7,500 |
| Very Active | 1.725 | Train most days, high daily activity | 3+/week | 2+ hrs/week | 7,500+ |
| Extra Active | 1.9 | Intense daily training or highly physical job | 5+/week | 3+ hrs/week | 10,000+ |
During the FLS itself: use the fixed multiplier of 1.55 for TDEE calculation regardless of your actual activity level.
When in doubt, choose the lower level. It is better to be conservative with your TDEE than to overestimate.
My activity level: ____________________ My TDEE multiplier: ______
I4. Refeed Planning Worksheet
Refeed schedule by Sprint Level:
| Sprint Level | Mid-Programme Refeed | Final Day Refeed |
|---|---|---|
| Level 1 — Lean | Day 7 | Day 14 |
| Level 2 — Moderate | Day 10 | Day 21 |
| Level 3 — Overweight | Day 14 | Day 28 |
Refeed carbs:
| Sprint Level | Carbs (g/kg LBM) |
|---|---|
| Level 1 — Lean | 7 g/kg |
| Level 2 — Moderate | 5 g/kg |
| Level 3 — Overweight | 3 g/kg |
The same carb target applies to both the mid-programme and final day refeed. Protein and fat stay the same as regular sprint days on all refeeds.
My refeed calculation: My sprint level carbs: ______ g/kg × LBM ______ kg = ______ g
| Day | Protein | Carbs | Fat |

I5. Diet Break Tracker
Duration: 14 days, mandatory. Begins the morning after the final sprint day.
Diet Break Macros:
| Macro | Formula | My Value |
|---|---|---|
| Protein | 2 g/kg LBM | ______ g/day |
| Fat | 27.5% of TDEE ÷ 9 | ______ g/day |

Activity adjustment for diet break TDEE:
| Sprint Activity Level | Diet Break Multiplier |
|---|---|
| Sedentary | 1.375 (bumped up to Lightly Active) |
| Lightly Active | 1.55 (bumped up to Moderately Active) |
| Moderately Active | 1.55 (no change) |
| Very Active | 1.725 (no change) |
| Extra Active | 1.9 (no change) |

Auto-adjustment trigger (check after Day 5–7):
Threshold = Day 1 weight × 1.02 = ______ kg
Is my Day 7 average weight above ______ kg?
-
YES: Reduce fat by 10% and carbs by 10%. Protein stays unchanged.
- New fat: ______ g × 0.9 = ______ g
- New carbs: ______ g × 0.9 = ______ g
- Protein: unchanged at ______ g
-
NO: Continue as planned. No adjustment needed.
I6. FLS Summary Card — All v2 Parameters
Sprint Levels
| Sprint Level | Male BF% | Female BF% | Duration | Refeeds |
|---|---|---|---|---|
| Level 1 — Lean | Below 16% | Below 25% | 14 days | Day 7 + Day 14 |
| Level 2 — Moderate | 16–25% | 25–35% | 21 days | Day 10 + Day 21 |
| Level 3 — Overweight | Above 25% | Above 35% | 28 days | Day 14 + Day 28 |
Sprint Macros (Regular Days)
| Macro | Level 1 | Level 2 | Level 3 |
|---|---|---|---|
| Protein base | 3.0 g/kg LBM (at BF% floor) — slides down toward 2.2 as BF% rises | 2.2–3.0 g/kg LBM — interpolated from your exact BF% position within the level | 2.2 g/kg LBM |
| Dietary fat | 30 g/day | 27 g/day | 25 g/day |
| Carbs | 50 g net target from non-starchy vegetables (fibre not counted); app allows up to ~70 g before flagging over | same | same |
| Calorie floor | 800 kcal minimum — if below, increase protein to reach floor. Additional protein grams = (800 − current calories) ÷ 4 | same | same |
Protein Sliding Scale (BF%-Based)
Protein is determined by body fat percentage within each sprint level. No activity adjustment. Scale interpolates linearly between level boundaries and is clamped to 2.2–3.0 g/kg LBM.
Refeed Macros
| Sprint Level | Refeed Carbs (g/kg LBM) |
|---|---|
| Level 1 — Lean | 7 g/kg |
| Level 2 — Moderate | 5 g/kg |
| Level 3 — Overweight | 3 g/kg |
Protein and fat stay the same as sprint days on all refeeds.
Diet Break (14 Days — Mandatory)
| Macro | Formula |
|---|---|
| Protein | 2 g/kg LBM |
| Fat | 27.5% of TDEE ÷ 9 |
| Carbs | Remaining calories after protein and fat |
Activity bump: Sedentary moves to 1.375. Lightly Active moves to 1.55. Others unchanged.
Auto-adjust trigger: If Day 7 average weight exceeds Day 1 weight × 1.02, reduce fat and carbs by 10% (protein unchanged).
