Recommendations

▸Eat to the phase: -500 cut, +300 lean bulk, maintenance recomp.
▸Hold protein near 2 g/kg and lift 3-5x weekly regardless of phase.

Understanding Your Result

Your Result: Score: 86/100

Typical range: BMI 18.5-24.9; protein 1.6-2.2 g/kg; total T 264-916 ng/dL; FFMI ~25 ceiling.

What This Means

The output converts weight, height, age and training into BMI, body fat, calories, macros, zones and timelines.

Why It Matters

Phase math removes guessing: deficits cut, surpluses build, protein protects muscle either way.

Professional Interpretation

Coaches track intake against TDEE, protein per kilo, and strength trends — single metrics never decide.

Estimates vs measures

Navy fat, Epley maxes and Cooper VO2 estimate within ~10% — trends beat absolutes.

Numbers vs symptoms

Hormone numbers need clinical context; fitness numbers need consistent inputs.

Recommendations

•Eat to the phase goal
•Protein 1.6-2.2 g/kg
•Test hormones mornings, twice
•Track trends, not single days

Educational Content

Introduction

This calculator turns body measures into targets, timelines and training zones.

Concept Explanation

Intake minus TDEE sets weight direction; protein per kilo sets muscle direction; test numbers read against lab bands.

Applications

▸Cut/bulk planning

▸Protein targets

▸Zone training

▸Strength loading

▸Hormone unit conversion

▸Goal timelines

Benefits

•Phase calorie targets
•Macro splits
•1RM-based loads
•Karvonen zones
•Reference-band reads

Limitations

•Estimate error ~10%
•Single-day noise
•Lab variance
•No medical diagnosis
•Population equations

Best Practices

•Weigh mornings fasted
•Tape consistently
•Retest monthly
•Confirm labs twice
•Pair scale with strength log

Common Misconceptions

Myth: BMI judges muscular men.

Truth: BMI screens populations; waist plus body fat judge individuals.

Myth: More protein always builds more.

Truth: Above ~2.2 g/kg, extra protein just becomes expensive carbs.

Myth: One low T lab means treatment.

Truth: Repeat morning labs with free T and symptoms before any conclusions.

Practical Tips

•Morning weigh-ins
•Tape monthly
•Protein each meal
•Sleep 7-9 h
•Test T mornings fasted
•Log training loads

Common Mistakes

Bulking too fast

Surpluses over ~500 kcal mostly add fat. Gain 0.25-0.5% monthly.

Cutting too hard

Crashes strip muscle and hormones. Lose 0.5-1% weekly max.

Single-measure verdicts

One weigh-in or lab is noise. Averages decide.

Ignoring waist

The scale plus waist tells the truth neither tells alone.

Evening hormone labs

Afternoon T sags 20%+. Test mornings, twice.

Zone-less cardio

Gray-zone training stalls bases. Polarize easy and hard.

Assumptions

This calculator makes the following assumptions to provide estimates:

Adult men: Equations fit adult male physiology.

Consistent measures: Same scale, tape tension and timing.

Lab variance noted: Ranges differ by assay; use your lab band.

Healthy baseline: Illness and medications shift numbers.

Estimate-grade: Field equations, not lab measures.

Limitations

Be aware of these limitations when using this calculator:

~10% estimate error: Navy, Epley and Cooper approximate.

Hydration noise: Water shifts scale and tape daily.

No diagnosis: Hormone reads are informational only.

Single snapshot: Trends across weeks decide phases.

Assay differences: Unit math is exact; reference bands are lab-specific.

Frequently Asked Questions

Answers to common questions about this calculator.

What is a healthy BMI for men?

18.5-24.9. Muscular men read high without excess fat — pair BMI with waist and body-fat estimates.

How is male body fat estimated?

The Navy method from waist, neck and height. Athletic men land 10-20 percent; essential fat is ~3-5.

What is BMR vs TDEE?

BMR is resting burn; TDEE multiplies by activity (1.2 sedentary to 1.9 very active). Eat below TDEE to lose, above to gain.

How much protein for muscle?

1.6-2.2 g per kilo daily, spread over 3-5 meals with 2.5+ g leucine each.

What is FFMI?

Fat-free mass index; ~25 marks the natural ceiling for most men. Above 26 with leanness is rare naturally.

What is waist-to-height ratio?

Waist divided by height; under 0.5 is the screening target for metabolic risk.

How fast should I cut or bulk?

Cut ~0.5-1% weekly; lean-bulk ~0.25-0.5% monthly. Faster moves cost muscle or add fat.

What is body recomposition?

Losing fat while gaining muscle — realistic for beginners, detrained and higher-fat lifters at maintenance calories.

How is 1RM estimated?

Epley: weight x (1 + reps/30). True maxes need testing; estimates guide loading.

What are heart-rate zones?

Karvonen zones from resting and max HR: Z2 base, Z4 threshold, Z5 VO2. Most volume belongs easy.

What is a good VO2 max for men?

Age-graded: 40s is good at 30, excellent at 50+. Cooper 12-minute distance estimates it.

What is fitness age?

Performance-equivalent age versus norms — trainable at any age through VO2, strength and body comp.
