The desi woman's guide to strength: 20s through 70s
Share
The short version
- Whey protein does not make women bulky. A meta-analysis of randomised controlled trials in women found whey supplementation increased lean mass by an average of just 0.37 kilograms, less than 1% of total body composition.
- Women have roughly one-tenth to one-fifteenth the testosterone of men, the hormone that drives muscle hypertrophy. Women physiologically cannot bulk easily.
- Women's protein and strength needs change across life. The 20s and 30s are about building peak muscle and bone reserves. Pregnancy and post-partum dramatically increase requirements. Menopause accelerates loss; resistance training is the most evidence-backed protection.
- Desi women in the UK face stacked risks: lower baseline muscle and bone, widespread vitamin D deficiency (one peer-reviewed study found 96% of UK South Asian women had inadequate levels), and cultural messaging that still treats strength training as masculine.
- Adequate protein at every meal, vitamin D supplementation, and two to three sessions a week of resistance work, in any form, are what the research supports across every life stage.
- As part of a varied and balanced diet and a healthy lifestyle, protein contributes to the maintenance of muscle mass and the maintenance of normal bones.
Most desi women are told, somewhere between their teens and their thirties, that strength training will make them look manly. That protein is for boys. That weights are for the gym, and the gym is for men. The fear of "getting bulky" gets passed between aunts, mothers, sisters, friends. By the time perimenopause arrives in a woman's mid-forties, she has spent twenty years avoiding exactly the dietary and physical habits that would have built her reserves for what comes next.
This is one of the most consequential pieces of health misinformation in the desi community, and the harm is greatest because it operates at every stage of life. The science is clear, has been clear for years, and almost nobody is telling desi women specifically. This piece walks through what the research actually shows, and what changes by decade, from a 20-year-old's body to a 65-year-old's, with the desi-specific risks layered on top.
The bulky myth, with the actual research
The fear that protein and strength training will make women look bulky is contradicted by every well-designed study on the question. The clearest evidence comes from a Purdue University meta-analysis published in Nutrition Reviews, which examined randomised controlled trials of whey protein supplementation in adult women.1
The reason is hormonal. Testosterone is the primary driver of muscle hypertrophy, and women produce roughly one-tenth to one-fifteenth the amount men do. Adult men typically have testosterone levels of 270 to 1,070 ng/dL. Adult women typically have 15 to 70 ng/dL. The hormonal environment required to build large, masculine muscle simply is not there in a woman's body, regardless of how much whey she drinks.2
The female bodybuilders that show up in the imagined version of "bulky" are training six days a week with extreme calorie surpluses, often supplementing with anabolic steroids. They are a vanishingly small subset of women, and their results are not what happens when a 28-year-old does two strength sessions a week and eats more dahi.
What protein and resistance training actually do for women: a modest increase in lean mass, a meaningful decrease in fat mass, improved body composition, better strength, and significantly better protection against age-related bone and muscle loss. The visible result is not bulk. It is what people usually call "toned."
What changes across a woman's life
Women's protein and strength needs are not constant. They change substantially across decades, and the desi-specific risks shift with them. Here is the evidence-based version of what each life stage actually requires.
In your 20s: build the reserve
This is the most important decade for women's lifelong bone and muscle health, and it is the one where the bulky myth does the most damage by stopping younger desi women from building the reserves they will need for the next sixty years.
Peak bone mass, the maximum density a woman's skeleton will ever reach, is laid down between adolescence and the late 20s. Hip bone mass peaks at 16 to 19, lumbar spine peaks at 33 to 40 according to the Canadian Multicentre Osteoporosis Study.3 The crucial finding: for each 0.5 standard deviation increase in peak bone mass, lifetime fracture risk decreases by approximately 40%.4 What you build in your 20s directly determines whether you fracture a hip at 75.
Muscle is similar. The 20s are when women's lean mass is at peak and when resistance training delivers the highest returns per session. Building it now means having more to draw down on later. The protein target is 1.0 to 1.2g per kg of body weight per day, distributed across three meals at 25 to 30g each. For most desi women in their 20s eating mainly home-cooked vegetarian food, hitting this requires deliberate effort: more dahi, eggs at breakfast, larger dal portions, paneer where it fits.
In your 30s: maintain peak, plan for what's coming
Bone mass is at peak and starts declining slowly from the mid-30s onward, around 0.5 to 1% per year.5 Muscle mass starts to follow. Protein needs remain the same as the 20s. The strength habits built in this decade are what makes menopause manageable rather than catastrophic when it arrives.
The 30s are also when most desi women face the greatest practical barriers to consistency: career pressure, young children, household responsibility that often falls on them. Resistance training does not need to be elaborate or time-consuming to be effective. Two 30-minute sessions a week of bodyweight squats, lunges, push-ups, and basic dumbbell or kettlebell movements meaningfully maintain bone and muscle. Carrying small children counts. Climbing stairs counts. Yoga with weight-bearing poses counts.
Pregnancy: protein needs jump significantly
This is one of the most under-discussed dietary changes in any woman's life and one that desi vegetarian women face with the least specific guidance. The WHO/FAO/UNU recommendations, validated for well-nourished Indian pregnant women in a peer-reviewed study using whole-body potassium counters, are: an additional 6.7g of protein per day in the second trimester and 21.7g per day in the third trimester, on top of the standard adult requirement.6 A 65kg woman who needed 65 to 78g daily before pregnancy needs 86 to 100g by the third trimester.
This matters for desi vegetarian women specifically because Indian dietary studies have found that lacto-vegetarian pregnant women in India routinely fall short of the protein requirement. A study of 627 pregnant women in Uttar Pradesh found that nearly half were following lacto-vegetarian diets with insufficient protein and inadequate intake of nine of eleven measured micronutrients.7 Plant protein digestion and absorption is also lower than animal protein in the same gut, particularly relevant for vegetarian women.
The practical fix during pregnancy: significantly more dahi, paneer, eggs (if eaten), pulses, and where appropriate a whey protein supplement to close the gap. This is not an aesthetic concern; inadequate maternal protein intake is associated with intrauterine growth restriction and low birth weight in observational studies. Speak to your midwife or GP about specific supplementation during pregnancy.
Post-partum and lactation: needs stay elevated
Lactation increases protein requirements by approximately 19g per day for the first 6 months, slightly less from 6 to 12 months.8 Combined with the demands of recovery from delivery and the practical reality of caring for a newborn, this is a period when most women under-eat protein significantly. The mother's body will prioritise the baby's needs, mobilising her own muscle protein if dietary intake is inadequate. This is one of the documented mechanisms behind post-partum muscle and bone loss in undernourished mothers.
For breastfeeding desi women, the same fix applies: a generous portion of dahi at every meal, eggs at breakfast where eaten, larger dal portions, and a whey protein supplement stirred into chai or food to fill the gap when appetite is unpredictable. As part of a varied and balanced diet and a healthy lifestyle, adequate protein contributes to the maintenance of muscle mass during recovery.
In your 40s: perimenopause begins, anabolic resistance starts
The decade where the cumulative effects of earlier choices start to show. Bone loss continues at around 0.5 to 1% per year, lean mass starts declining more measurably, and oestrogen levels begin fluctuating in the years before periods stop. Many women describe feeling less strong, recovering more slowly, and noticing weight redistribution toward the abdomen. These are real physiological changes, not imagination.
Protein needs nudge upward. Most research now recommends 1.0 to 1.2g/kg minimum for women over 40, with the higher end favoured for those doing resistance training. Anabolic resistance, the term researchers use to describe the body's reduced efficiency at building muscle from the same dietary protein, becomes meaningful in this decade.9 The same protein intake that maintained muscle at 30 will not maintain it at 45. Distributing protein across three meals each delivering 25 to 30g becomes more important, not less.
Menopause and beyond (50s, 60s, 70s+)
Oestrogen drops sharply during menopause, and bone and muscle loss accelerate together. Peer-reviewed research shows postmenopausal women have approximately 5.7% less lean mass than premenopausal women.10 Bone loss in the first five years after menopause can be as high as 2 to 3% per year, building to a 15 to 35% loss in bone mass within those five years.5 Women in their seventies and eighties face significantly higher fracture risk than men of the same age.
The interventions are well-established. Protein at 1.2 to 1.6g per kg, distributed across three meals each delivering at least 25 to 30g. Resistance training at moderate-to-high intensity (≥70% of one-rep max), three times per week, with a 2023 network meta-analysis of 919 postmenopausal women confirming significant improvements in bone mineral density at the spine, femoral neck, and total hip.11 Vitamin D supplementation is non-negotiable for UK desi women (see below). Hormone replacement therapy is now considered safe and effective for many women and is worth a conversation with a GP for those whose menopause symptoms are significant.
Why desi women face a steeper version of the curve at every stage
Three risks stack on top of each life-stage challenge.
Lower baseline muscle and bone
South Asian women on average start with less muscle mass and lower bone density than white European women at the same BMI, part of a body composition pattern researchers describe as the South Asian phenotype.12 Less muscle and less bone to begin with means less reserve to draw down on as decline begins. The same percentage decline has a bigger functional impact when the starting point is lower.
Widespread vitamin D deficiency
Vitamin D is essential for bone health, calcium absorption, and muscle function. A peer-reviewed study published in Bone of 78 young UK South Asian women aged 18 to 36 found that 96% had serum 25-hydroxyvitamin D levels below 15 ng/ml, and approximately a quarter had marked deficiency.13 A more recent cross-sectional study of 120 UK South Asian women aged 60 and over found that low vitamin D status was associated with reduced muscle strength and physical function.14
The mechanism is largely physical: melanin in darker skin acts as a partial barrier to UVB synthesis of vitamin D, the UK has limited UVB-appropriate sunlight outside April to October, and many desi women have lower outdoor exposure for cultural and lifestyle reasons. The deficiency starts in the 20s and continues for life if not addressed. It compounds bone loss at every stage, and especially around menopause.
The NHS recommends that all UK adults consider taking 10 micrograms of vitamin D daily during autumn and winter, and that those at higher risk including people with darker skin should consider taking it year-round.15 For UK desi women, this is not optional. Speak to your GP about testing your levels.
Cultural messaging that still treats strength as masculine
Beyond the biology, desi women face decades of social messaging that strength training is unfeminine, that visible muscle is unattractive, and that protein is a male concern. This isn't just a small barrier. It actively shapes what women try in their 20s, what they tell their daughters, and what they accept for themselves as ageing accelerates. Many of the women now hitting perimenopause have never lifted a weight and have no peer or family models for doing so.
The result is that desi women across every decade are facing compounding challenges: lower starting muscle and bone, vitamin D deficiency that worsens bone loss, life-stage demands that increase protein needs without anyone telling them, and no cultural permission to address any of it through the methods the research most strongly supports.
What the research actually says works at every stage
Two interventions, both well-established, both required, neither optional. The dose changes by life stage; the principles do not.
Resistance training
For all adult women, the protocol with the strongest evidence is moderate-to-high intensity resistance training (≥70% of one-rep maximum), three times per week. A 2025 meta-analysis confirmed this protocol as the most effective for bone density improvements in postmenopausal women,16 but the same principles apply to younger women building peak reserves. The "heavy" part of "heavy lifting" is doing real biological work: bones respond to mechanical load. Light walking and stretching, while valuable for cardiovascular and mobility reasons, are not enough.
What this looks like for someone starting from zero: bodyweight squats, then squats holding a bag of rice, then a kettlebell, then a barbell at the gym. Carrying shopping in both hands. Climbing stairs deliberately. Yoga that involves weight-bearing poses. Resistance bands for upper body. Two to three sessions a week. The form matters; the equipment does not.
Adequate protein, distributed across meals
The target shifts with life stage. For most desi women, hitting it requires deliberate effort because traditional meals tend to concentrate protein in lunch.
| Life stage | Protein target (g/kg/day) | Example: 65kg woman |
|---|---|---|
| 20s and 30s (non-pregnant) | 1.0 to 1.2 | 65 to 78g/day |
| Second trimester pregnancy | 1.0 to 1.2 + 6.7g | 72 to 85g/day |
| Third trimester pregnancy | 1.0 to 1.2 + 21.7g | 87 to 100g/day |
| Lactating (0 to 6 months) | 1.0 to 1.2 + 19g | 84 to 97g/day |
| 40s | 1.0 to 1.2 | 65 to 78g/day |
| Postmenopausal, with resistance training | 1.2 to 1.6 | 78 to 104g/day |
How to actually deliver enough protein for a desi woman
Practical changes that make the most difference at every life stage:
- An egg or two at breakfast. The single biggest gap in most desi diets is breakfast. Two eggs add 12g of protein to a meal that typically delivers 5 to 8g. Combine with toast, paratha, or a plain dahi pot for a complete meal.
- A larger portion of dahi at every meal where it fits. A full bowl of plain dahi (around 170g) adds 12 to 17g of protein. Easiest single change.
- Bigger dal portions. Two bowls instead of one adds 6 to 7g.
- Paneer in more dishes. 50g of paneer in a sabzi adds 9g. 100g portions push it to 18g.
- Whey isolate where it fits. Two teaspoons of Heldi Chai across the day's two cups of chai adds 6g of protein quietly. Two tablespoons of Heldi Dahi in raita adds 20g of protein to a single bowl, taking it from 5g to 25g and turning it into a near-complete protein meal.
The bigger picture
The version of femininity that most desi women have inherited treats strength as masculine, food restriction as virtuous, and self-care as selfish. Each of these messages has a cost in the 20s, when peak reserves should be built. A bigger cost in the 30s, when those reserves start to slip. A bigger cost again in pregnancy and lactation, when protein needs spike. And the largest cost in the decades around menopause, when bone and muscle decline accelerate and the body's tolerance for under-eating protein and avoiding load drops to zero.
The research does not support eating less. It does not support endless cardio. It does not support avoiding weights to stay "feminine." It supports adequate protein at every meal, supplementing vitamin D, and making the body do meaningful physical work two or three times a week. Done consistently from the 20s onward, this is the difference between a 70-year-old who walks briskly through Tesco unaided and one who can no longer carry a full kettle from the sink to the hob.
The science is clear. The cultural permission is what's been missing.
Frequently asked questions
Will whey protein make me bulky as a woman?
No. A Purdue University meta-analysis of randomised controlled trials in women found whey protein supplementation increased lean body mass by an average of just 0.37 kilograms, less than 1% of total lean mass.1 Women have roughly one-tenth to one-fifteenth the testosterone of men, the hormone that drives muscle hypertrophy, which means the physiological environment required to build large masculine muscle is not present in a woman's body.
How much protein should I eat in my 20s and 30s?
Around 1.0 to 1.2g of protein per kilogram of body weight per day, distributed across three meals each delivering 25 to 30g. For a 65kg woman, that is 65 to 78g daily. Most desi women in their 20s and 30s eating predominantly home-cooked vegetarian food fall well below this. The 20s in particular are when peak muscle and bone mass are built, and protein and resistance training during this decade have outsized lifelong benefits.
How much extra protein do I need during pregnancy?
The peer-reviewed estimates, validated for Indian pregnant women, are an additional 6.7g of protein per day in the second trimester and 21.7g per day in the third trimester, on top of the standard 1.0 to 1.2g/kg base.6 A 65kg woman needs 86 to 100g of protein daily by the third trimester. Lactating women need approximately 19g additional per day for the first 6 months.8 Lacto-vegetarian Indian women routinely fall short of these targets.
Is whey protein safe during pregnancy and breastfeeding?
Whey protein is generally considered safe during pregnancy and breastfeeding for women without dairy allergies, as it is a milk-derived food and pregnant women already consume dairy in standard nutritional guidance. As with any supplement during pregnancy, speak to your midwife or GP before starting. The bigger evidence-based concern in pregnancy is under-consuming protein, not over-consuming it.
Is strength training actually safe for women in their 50s and 60s?
Yes, and it is the most evidence-backed intervention for postmenopausal bone loss. A network meta-analysis of 19 randomised controlled trials covering 919 postmenopausal women confirmed that resistance training significantly improves bone mineral density at the spine, hip, and femoral neck.11 The recommended protocol is two to three sessions per week at moderate-to-high intensity. Women starting from no fitness base should progress gradually, ideally with supervision for the first few sessions.
Why are South Asian women at higher risk of osteoporosis?
Three reasons stack: lower baseline bone mass and lean muscle mass than white European women, widespread vitamin D deficiency in the UK desi population (one peer-reviewed study found 96% of young UK South Asian women had inadequate vitamin D), and the cumulative effect of menopausal bone loss on top of these starting positions.13 Addressing vitamin D, protein intake, and resistance training together is more effective than tackling any single one alone.
Do I need vitamin D if I drink milk and eat dahi every day?
Probably yes. Dietary vitamin D is genuinely hard to get from milk and dahi alone, especially in the UK where sunlight provides limited UVB synthesis from October to March. The NHS recommends 10 micrograms daily during autumn and winter for all UK adults, and year-round for people with darker skin. UK South Asian women in particular have well-documented widespread deficiency.15 Speak to your GP about testing your levels.
Can I just walk instead of doing strength training?
Walking is excellent for cardiovascular health and mobility, but it is not enough to maintain or improve bone density. Bones respond specifically to mechanical loading, which means weight-bearing through the joints. Walking provides some load through the legs but very little through the spine, hip, and upper body where postmenopausal fracture risk is highest. Resistance training is the intervention with the strongest evidence for bone density outcomes.16
