How many of us look at ourselves in the mirror and wonder how our body has changed over time? Ever felt bad for the flattened curves, the stubborn belly pooch, flabby arms, or double chin — and sighed thinking of your body in your teens and 20s?
Have there been frustrating moments in your weight loss journey when the number on the scale just wouldn't budge despite all your efforts?
We are all critical of our looks and weight. Adding fuel to the fire are those unwarranted comments from people you meet after years — and to think of it, it is mostly women!
But is body weight the true indicator of our health? What actually defines a healthy body in midlife?
Weight Gain During the Menopausal Transition
Perimenopause is a life stage involving major metabolic changes as a cascading consequence of declining reproductive hormones.
Fat metabolism and insulin/energy metabolism shift significantly as estrogen dips and fluctuates. Menopausal symptoms — especially sleep disturbances, mood changes, and night sweats — put the body under additional stress, increasing secretion of the stress hormone cortisol. This leads to disproportionate fat deposition in the midsection and excessive hunger, pushing many women into a vicious cycle of overeating yet feeling fatigued. The resulting insulin resistance and high blood pressure elevate the risk of type 2 diabetes and hypertension in the post-menopausal years.
A 2023 Lancet Regional Health analysis of NFHS-5 data — drawing on data from nearly 700,000 Indian participants — found that estimating BMI alone is insufficient for Indian women, as abdominal obesity and healthy BMI can coexist and carry distinct metabolic risks. This is especially relevant at midlife, when hormonal shifts accelerate visceral fat accumulation regardless of overall weight.
Many of these metabolic changes can be picked up by simple blood tests. Miyara
brings the essential tests for women to your doorstep.
Awareness in this regard is critical — for accepting bodily change and shifting focus to broader wellness goals: toning muscles, improving energy and mood, reducing aches, and switching to healthy eating. If you are struggling with sudden weight gain or body image issues in midlife, it may be time to rethink what healthy aging actually means.
Know Your Health Metrics
Before chasing a number on the scale, it helps to understand what the metrics actually measure — and which ones matter most.
Body weight alone has no evident correlation with health outcomes. It says nothing about what your body is made of.
BMI (kg/m²) adjusts weight for height and can serve as an initial obesity indicator — but it is not a measure of body fat, despite being popularly treated as one. Critically for Indian women: Asian populations carry greater visceral adiposity at lower BMI levels than Western populations, which is why India's obesity cut-off is set at ≥23 kg/m² — well below the global threshold of ≥30 kg/m². A "normal" BMI in Western terms may still carry significant metabolic risk for Indian women.
Waist-to-hip ratio (WHR) and waist-to-height ratio (WHtR) are more meaningful in practice. A systematic review and meta-analysis in Obesity Reviews, drawing on data from over 300,000 adults across multiple ethnic groups, found WHtR outperforms both BMI and waist circumference in detecting cardiometabolic risk — including hypertension, type 2 diabetes, and cardiovascular disease. A simple rule of thumb: keep your waist measurement to less than half your height. WHR is also a significant predictor of mortality in women with heart failure.
Body composition analysis is the most comprehensive approach — evaluating water content, fat mass, lean mass, and bone density. Bioimpedance scales send short electric pulses through the body and measure their return time to estimate fat and bone content (poor electrical conductors). DEXA scan is the gold standard for both bone density and lean/fat mass measurement.
Body fat composition — not scale weight — is what matters for healthy aging. Simpler methods like skinfold calipers exist, but ultrasound, bioimpedance, underwater weighing, and DEXA are more reliable, with the last two considered gold standards.
The Scale Is Not the Goal
A 2024 review in Diabetes/Metabolism Research and Reviews confirms what multiple studies have now shown: some individuals classified as obese by BMI have lower cardiovascular risk and a healthier metabolic profile, while a significant subset of "normal-BMI" people are metabolically unhealthy and face increased mortality risk. An estimated 5–45% of people with a normal BMI are metabolically unhealthy. The inverse is also true.
This is not a reason to ignore weight — it is a reason to measure the right things. The number on your weighing scale is not your ultimate goal. Your metabolic health, muscle quality, visceral fat distribution, and energy levels are.
