METABOLIC HEALTH
Thin outside. Fat inside.
If you're South Asian and your weight looks normal on paper, your metabolic risk may not be. TOFI describes men who carry dangerous fat around the organs while looking unremarkable in the mirror.
Your BMI is lying to you
BMI measures weight, not where fat sits. Visceral fat , the kind wrapped around your liver and pancreas drives insulin resistance, raises inflammation, and lowers testosterone. Subcutaneous fat, the kind you can pinch, does far less damage.
South Asian men carry more visceral fat at every BMI than men of European descent. That's why standard cutoffs miss it.

EARLIER ONSET OF HEART DISEASEWhere testosterone comes in
Fat tissue converts testosterone to estradiol. More visceral fat means more conversion and less available testosterone which makes it harder to build muscle and easier to store fat around the middle. The cycle tightens over years, quietly.

Different thresholds, different risk
| Measure | Standard cutoff | South Asian cutoff |
|---|---|---|
| Overweight (BMI) | 25.0 | 23.0 |
| Obesity (BMI) | 30.0 | 27.5 |
| Waist circumference (men) | 40 in / 102 cm | 35 in / 90 cm |
A South Asian man at BMI 24 with a 36–inch waist is "normal weight" by standard criteria — and already past the threshold that applies to him.
What we actually measure
A standard physical won't find this. We test the markers that reveal visceral fat and insulin resistance before they become a diagnosis.
Hormonal
Total and free testosterone, SHBG, estradiol, LH and FSH, thyroid function
Metabolic
HbA1c, fasting glucose and insulin. HOMA-IR, liver enzymes, triglyceride-to-HDL ratio
Cardiovascular
Full lipid panel, APOB, lipoprotein(a), hs-CRP, blood pressure
Body composition
Waist circumference, waist—to-height ratio, body fat percentage and distribution
How we treat it
Visceral fat responds. It's often the first fat to move — but only when the plan targets the actual driver rather than the number on the scale.
Hormone optimization
Where labs confirm deficiency, restoring testosterone to mid-normal range improves lean mass and reduces visceral adiposity interrupting the cycle at its source.
GLP-I therapy
Semaglutide and tirzepatide reduce visceral fat and improve insulin sensitivity. Paired with adequate protein and resistance training to protect muscle.
Targeted peptides
Tesamorelin is FDA-approved specifically for the reduction of visceral adipose tissue, and is considered where clinically appropriate.
Metabolic foundation
Nutrition built around how you actually eat, resistance training, sleep, and ongoing lab monitoring not a generic plan.
