Formulas Used

Visceral Fat Score

visceral_score = round((waist_cm - 65) / 5 + age / 15 + bmi_val / 8)

Waist Circumference Risk

waist_risk = waist_inches >= 40 ? 1 : 0

BMI

bmi_display = bmi_val

Variables

Variable	Description	Default
`waist_inches`	Waist Circumference(inches)	36
`age`	Age(years)	35
`weight_lbs`	Body Weight(lbs)	180
`height_inches`	Height(inches)	70
`bmi_val`	Derived value`= (weight_lbs * 703) / (height_inches * height_inches)`	calculated
`waist_cm`	Derived value`= waist_inches * 2.54`	calculated

How It Works

Visceral Fat Estimation

Visceral fat surrounds internal organs and is strongly linked to metabolic disease. While a DEXA or CT scan provides exact measurement, waist circumference and BMI are practical proxies.

Scoring Model

Score = (Waist(cm) - 65) / 5 + Age / 15 + BMI / 8

Risk Levels

| Score | Level | |---|---| | 1-9 | Normal | | 10-14 | Elevated | | 15+ | High |

Waist circumference above 40 inches for men is an independent risk factor.

Worked Example

A 35-year-old male, 180 lbs, 70 inches, 36-inch waist.

waist_inches = 36age = 35weight_lbs = 180height_inches = 70

01BMI = (180 x 703) / (70 x 70) = 25.8
02Waist = 36 x 2.54 = 91.4 cm
03Score = (91.4 - 65) / 5 + 35 / 15 + 25.8 / 8
04= 5.3 + 2.3 + 3.2 = 11 (Elevated)
