This check uses reference points developed for Indian adults. It looks at body and waist, muscle and strength, blood pressure, and eating or weight changes separately, so an important result is not hidden by normal results elsewhere.

About you

Age and sex help us compare your measurements with the right reference ranges.

Personalises your report.

Enter a 10-digit Indian mobile number. A +91 prefix is accepted.

Adults 18 and over. From age 82, scale body-composition numbers are shown only for tracking.

Choose the setting used on your body composition scale.

5′0″ = 152 · 5′4″ = 163 · 5′8″ = 173 · 6′0″ = 183

Light clothing, no shoes, same scale each time.

This personalises the advice. It does not change your result.

Safety check

How body composition readings work

These bands apply to Omron HBF-702T outputs. All device fields are optional.

Read this first. Device bands are manufacturer references, not Indian clinical thresholds or diagnoses. Waist, waist-to-height ratio and blood pressure carry more clinical weight.

Body fat percentage chart for men and women

Omron reports a 3.5-point SEE. The shown ±3.5-point band is an illustrative uncertainty aid, not guaranteed limits for one person. Compare the same device under matched conditions.

This percentage is not appendicular muscle mass and cannot test for sarcopenia.

Visceral fat level: what the number actually means

15 and overVery highStrengthens a central-fat picture; check waist alongside

A manufacturer scale, not a scan or area measure. It cannot diagnose visceral obesity or replace waist measurement.

BMI for Indians: why the threshold is 23, not 25

Risk appears at a lower BMI in Asian Indians; WHO is shown separately.

Waist circumference, waist-to-height and waist-to-hip

MeasureAction threshold
Waist, men90 cm and over
Waist, women80 cm and over
Waist-to-height under 0.40Below the central-fat screening range; do not reduce further from this result alone
Waist-to-height 0.40 to 0.49Waist is under half your height
Waist-to-height 0.50 to 0.59Waist is more than half your height; risk starts to rise
Waist-to-height 0.60 and overHigh central-fat range
Waist-to-hip ratioAction point 0.90 men / 0.85 women; supporting measure only

Keep your waist under half your height. Measure midway between the lowest rib and hip bone after a normal breath out, not at the navel. Waist-to-hip describes body shape, but waist-to-height and waist centimetres are simpler progress measures.

Calf circumference and muscle reserve after 60

AgeMenWomen
60 and overLow under 34 cmLow under 33 cm
Under 60Recorded and tracked, but no low category is assigned

Measure both calves standing with a non-stretch tape and use the larger unaffected value. A lower result is an invitation to check strength—not a diagnosis. A result above the cut-off does not prove normal strength.

Resting metabolism and body age: no threshold to read

Resting metabolism is equation-based, not measured calorimetry or a calorie prescription. Body age is derived from the readings above, adds no clinical information and has no accepted cut-off. Neither changes the report.

What you need before you start

  • Essential. Age, sex, height, weight and a waist measurement. That alone produces a usable report.
  • Strongly recommended. Two blood pressure readings a minute apart, after sitting quietly for five minutes.
  • Optional. Body fat, skeletal muscle and visceral fat from your monitor, plus both calf measurements.
  • Do not use a body composition monitor if you have a pacemaker or another implanted electronic device, or during pregnancy. The rest of the report still works without those readings.

Questions people ask about these numbers

Answers drawn from the Asian Indian consensus, NICE NG246, AWGS 2019, IDF, WHO and GLIM.

Why BMI 23 instead of 25?

Diabetes and cardiovascular risk appear at a lower BMI in Asian Indians. This tool uses 18.5–22.9 as the lower-risk range, 23.0–24.9 as increased risk and 25+ as obesity by Indian criteria, while showing WHO categories separately.

How do I read waist-to-height and waist-to-hip?

Waist-to-height is the main home target: keep your waist below half your height. From 0.50 to 0.59, risk starts to rise; 0.60 or more needs greater attention. Waist-to-hip is a supporting body-shape check, with WHO action points of 0.90 for men and 0.85 for women. Use waist centimetres and waist-to-height to track progress.

How accurate is the body fat percentage from a home monitor?

Home BIA estimates rather than measures fat. Omron reports a 3.5-point SEE, not guaranteed individual limits. Compare matched readings over months; waist carries more clinical meaning.

Can I use one of these devices with a pacemaker?

No. Do not use BIA with a pacemaker, ICD or other implanted electronic device. The non-BIA report still works from BMI, waist, calf, blood pressure, history, nutrition and function.

Why does my calf measurement only count from age 60?

From age 60, a larger unaffected calf below 34 cm in men or 33 cm in women suggests that a strength check would be helpful. Below 60, the number is kept only as a personal baseline. Calf size alone cannot diagnose muscle loss or prove that strength is normal.

Can this tell me whether I have metabolic syndrome?

No. IDF assessment needs central obesity plus two further factors. Diagnosed diabetes and qualifying BP can be recognised, but this tool lacks triglyceride and HDL values; “high cholesterol” cannot replace them. It explains known and missing information without a score or diagnosis.

My reading was high. Do I have high blood pressure?

Not from one session. Repeat on different days. Review is warranted for a home average at or above 135/85 or clinic readings at or above 140/90; 180/120 needs same-day attention.

What is "normal-BMI central adiposity"?

A lower-risk Indian BMI with a waist at or above 90 cm in men, 80 cm in women, or more than half the person's height. A normal BMI never cancels a raised waist; this remains a measurement pattern, not a diagnosis.

Why won't the tool give me one overall score out of 100?

Adding BMI, waist and BIA would count overlapping adiposity signals repeatedly, while averaging could hide dangerous BP. Domains remain separate and safety overrides stand on their own.

IMPORTANT NOTES

Not a diagnosis. Screening for adults 18+; pregnancy limits apply.

Indian thresholds by default. WHO categories shown alongside, never mixed silently.

Device readings are estimates. Labelled as device reference bands, not clinical cut-offs.

Educational screening only, and not a substitute for medical or dietetic assessment. Do not use a body composition monitor with a pacemaker or other implanted electronic device. Body composition results are not interpretable in pregnancy, generalised swelling, abdominal fluid, dialysis or acute illness. Blood pressure results here are screening values. Hypertension is diagnosed on readings taken on two separate days by a clinician. Seek medical advice for unexplained weight loss, reduced eating, weakness, falls, swelling or any concerning symptom.
