You’ve probably been told at some point that your risk of Type 2 diabetes is high, or that you need to watch your diet more carefully than your Western colleagues do, or that your body stores fat differently. You’ve probably attributed it to genetics or lifestyle or just the inexplicable unfairness of biology.

Here’s another explanation, and it’s one that both modern science and ancient Indian medicine have been converging on from different directions: you may be metabolically efficient to a fault because your body — or more precisely, your ancestors’ bodies — learned to survive disasters that you never experienced. And that learning, encoded not in the DNA sequence but in its chemical tags, has been passed down through generations, running in your metabolism right now.

This is epigenetics applied to history. And India’s history has produced one of the most significant cases of population-wide epigenetic burden anywhere on earth.

Between the Great Bengal Famine of 1770 (which killed an estimated 10 million people — roughly a third of Bengal’s population), the Victorian-era famines of 1876-78, 1896-97, and 1899-1902 (each killing millions), and the Bengal Famine of 1943 (1.5-4 million deaths, under British colonial administration during World War II), South Asian populations endured repeated, severe, multigenerational nutritional deprivation. The survivors survived by becoming exquisitely efficient at storing energy — at conserving every calorie, at maximising fat storage, at downregulating metabolic rate during scarcity. These were brilliant adaptations for the conditions they faced.

Now those same adaptations are running in a 21st-century body in a Mumbai high-rise or a London suburb or a Houston suburb, surrounded by hyperpalatable food and a sedentary lifestyle. The survival genius has become a disease mechanism. And the mechanism is written in the epigenome.

The DNA sequence — the 3 billion base pairs that encode the human genome — is often described as a blueprint. That framing is misleading in an important way: a blueprint is static. It doesn’t change based on what the building experiences after construction. The genome is more dynamic than that. It’s more like a script, with actors who can decide which lines to deliver loudly, softly, or not at all.

Epigenetics — from the Greek ‘epi,’ meaning above or on top of — is the study of changes in gene expression that don’t involve changes to the DNA sequence itself. The letters of the genetic code stay the same. What changes is how those letters are read. The primary mechanism is DNA methylation: the addition of a methyl group (-CH3) to a cytosine nucleotide at what are called CpG sites. Methylation typically suppresses gene expression — it’s the equivalent of putting tape over specific words in the script. The word is still there. But the actor can’t read it.

Here’s what’s critical to understand: these methylation marks can be influenced by environment. Nutrition, stress, toxins, exercise, temperature, psychological experience — all of these can modify the pattern of methylation across the genome. And critically, some of those changes can persist. A gene that was suppressed by famine conditions in a parent might remain suppressed in the child, even if the child has never experienced famine. That’s the mechanism behind transgenerational epigenetic inheritance. And that’s the mechanism that connects India’s colonial history to South Asian bodies today.

In the final winter of World War II, a German blockade cut off food and fuel to the western Netherlands. Between November 1944 and April 1945, about 4.5 million Dutch civilians survived on 400 to 800 calories per day — roughly a quarter of normal intake. Approximately 20,000 people died.

For epidemiologists and geneticists, the Dutch Hunger Winter became something else: the most precisely documented natural experiment in human transgenerational epigenetics. The timing was discrete, the geography was bounded, the caloric restriction was severe and well-documented, and the Dutch civil registration system meant that researchers could identify specific individuals who had been conceived, gestated, or born during the famine period and track their health outcomes across their entire lives.

The first major finding came from Heijmans et al. (2008) in the Proceedings of the National Academy of Sciences: DNA methylation differences at the IGF2 locus were detectable in people who had been prenatally exposed to the famine — and those differences were still present more than 60 years after the famine ended. The epigenetic mark had survived six decades. This was the first definitive human evidence that prenatal famine exposure produces heritable epigenetic changes.

A 2024 BMC Medicine paper by Taeubert, Kuipers, Heijmans and colleagues took the research further than ever. They profiled 944 Dutch Hunger Winter Families Study participants on 168 different serum metabolic biomarkers using nuclear magnetic resonance metabolomics. The result: prenatal famine exposure produces a distinctive metabolic signature that resembles the biomarker profiles of multiple chronic diseases simultaneously — cardiovascular disease, Type 2 diabetes, insulin resistance disorders, and more. The body of someone exposed to the Dutch Hunger Winter in utero looks metabolically like someone carrying elevated risk of several major diseases at once. Not because they’re sick, necessarily. Because their metabolism was configured for conditions that no longer apply.

The 2026 Frontiers in Genetics review concluded: ‘Advances such as epigenome-wide association studies (EWAS), high-throughput methylation profiling, and multi-omics integration now enable unbiased, genome-scale discovery of environmentally responsive epigenetic variation.’ The field has moved from documenting that these marks exist to mapping their precise genome-wide distribution and clinical consequences.

The Dutch Hunger Winter was one famine. Six months. One region. 400-800 calories per day. 20,000 deaths. And it left epigenetic marks detectable 60 years later.

Now consider India’s famine history under colonial rule.

The Great Bengal Famine of 1770 killed approximately 10 million people — estimates suggest roughly a third of Bengal’s entire population. It occurred within a decade of the British East India Company acquiring diwani rights (revenue collection) over Bengal. The Company’s revenue extraction and its policy of raising land taxes even during crop failure has been extensively documented as a major contributing cause.

The Victorian era produced multiple catastrophic famines across India: Madras and Bombay provinces in 1876-78 (5.5 million deaths), followed by the Indian Famine of 1896-97 and the Great Indian Famine of 1899-1902. Each was characterised by crop failure amplified by colonial export of food, inadequate famine relief, and revenue extraction that continued even as populations starved. Mike Davis’s ‘Late Victorian Holocausts’ (2001) documented that food often left India’s ports for Britain during these events while the local population died.

The Bengal Famine of 1943 — the most thoroughly documented — killed between 1.5 and 4 million people in a Bengal that was simultaneously supplying rice to British forces in Burma and whose food stocks had been commandeered as part of wartime policy. Amartya Sen’s analysis showed it was not a food shortage in the conventional sense but a distribution failure driven by political decisions. Winston Churchill’s refusal of famine relief has been extensively documented by historians.

What does this history mean epigenetically? Each of these events subjected populations — during the most epigenetically sensitive period of human development (prenatal and early postnatal) — to caloric restriction comparable to or exceeding the Dutch Hunger Winter. Unlike the Netherlands, India’s events were not isolated. They were repeated, generation after generation, across multiple regions, potentially compounding the epigenetic inheritance across multiple generational layers.

The epigenetic changes induced by prenatal famine exposure don’t happen randomly. They affect specific genes in specific, metabolically logical ways. Understanding which genes are affected explains why the South Asian metabolic phenotype looks the way it does.

Insulin-like growth factor 2 is an imprinted gene — the paternal copy is normally active, the maternal copy normally silenced. During prenatal famine, hypomethylation (reduced methylation, resulting in increased expression) at the IGF2 locus appears to produce offspring with metabolic programming oriented toward energy storage and conservation. Adults with prenatal IGF2 hypomethylation show elevated insulin resistance, higher propensity for central fat accumulation (visceral adiposity), and increased Type 2 diabetes risk. This is the most documented epigenetic mechanism in human famine inheritance.

Leptin, encoded by the LEP gene, is a hormone that reduces appetite and regulates fat storage. During famine, increased LEP methylation altered leptin signalling in ways that conserved energy — essentially turning up the body’s fat-storage drive. This was a survival advantage then. In a modern caloric environment, descendants with inherited LEP methylation patterns show a tendency toward easier fat gain and more difficult fat loss than their metabolic inputs would predict.

Adiponectin (ADIPOQ) improves insulin sensitivity and facilitates fat breakdown. Epigenetic suppression of ADIPOQ during famine conditions slows fat metabolism — another energy-conservation adaptation. Descendants with inherited ADIPOQ methylation show lower adiponectin levels, which predisposes them to insulin resistance even at moderate body weights. This explains a specific feature of South Asian metabolic syndrome: insulin resistance and Type 2 diabetes at BMI levels that would be considered normal or even low in Western populations.

South Asians develop Type 2 diabetes risk by age 25 on average; white Europeans face comparable risk around age 40. South Asian adults show metabolic syndrome at lower BMI — a phenomenon sometimes called the ‘South Asian phenotype’: relatively lean body with disproportionately high visceral fat, high insulin resistance, and poor lipid profiles at lower absolute weight. PCOS prevalence in South Asian women runs 8-22% in recent Indian urban studies. South Asians show elevated rates of non-alcoholic fatty liver disease at lower body weight than other populations.

These are not random genetic differences. They’re metabolic configurations — and the epigenetic evidence from famine research suggests a plausible historical mechanism. Populations subjected to repeated, severe, multigenerational food insecurity would predictably develop inherited epigenetic configurations that maximise energy storage, reduce energy expenditure, and maintain fat reserves against anticipated future scarcity. In the 21st century, against a backdrop of increasingly available refined foods and sedentary urban lifestyles, these configurations produce epidemic metabolic disease.

The epigenetic burden of Indian history is not limited to nutritional deprivation.

The 1947 Partition of British India into India and Pakistan constituted one of the largest forced migrations in human history: 10-20 million people displaced across newly created borders, between 200,000 and 2 million killed in communal violence that consumed Punjab and Bengal simultaneously, and the creation of an entire generation that experienced acute collective trauma, loss, and profound psychological dislocation.

Rachel Yehuda’s research on Holocaust survivors and their children established the template for understanding how collective trauma transmits epigenetically. She found lower cortisol levels and altered methylation of the FKBP5 gene — a key regulator of the stress-response system — in children of Holocaust survivors, particularly those whose mothers had PTSD. The Partition of India involved trauma of comparable scale and horror, occurring in a single year to populations already weakened by the Bengal Famine of 1943 and decades of colonial displacement.

What are the epigenetic consequences of Partition trauma in its second and third generation descendants? The honest answer is: we don’t fully know, because systematic epigenetic research on Partition survivors and their descendants hasn’t been done at the scale that Holocaust research has. But based on the mechanisms Yehuda identified, we would expect: altered glucocorticoid receptor methylation, altered stress-response system calibration, potentially elevated rates of anxiety and depressive disorders in descendants, and altered vulnerability to PTSD in response to subsequent adversity.

The multigenerational experience of caste-based discrimination, poverty, social exclusion, and violence that Dalit and marginalised caste communities in India have endured constitutes another form of historical trauma with potential epigenetic consequences. Research on multigenerational poverty in other contexts has found epigenetic markers associated with chronic stress exposure and reduced cognitive and physical health outcomes that partially transmit to the next generation. India’s caste system operated as a system of hereditary poverty and social exclusion for thousands of years. The epigenetic consequences of this history in affected communities have never been systematically studied — a significant gap in Indian public health research.

Charaka Samhita’s discussion of bodily constitution and its origins contains what may be the oldest systematic framework for thinking about what we now call epigenetics.

The Sanskrit concept of Beeja — literally ‘seed’ — refers to the inherited biological potential transmitted from parent to offspring through the Shukra (sperm) and Shonita (ovum). This is the closest Ayurvedic equivalent of the genotype. But Charaka doesn’t stop at Beeja. He equally emphasises Kshetra — the field in which the seed develops. The Kshetra includes: the nutritional status of the mother, her emotional and psychological state during pregnancy, the quality of food and water in the environment, and the accumulated health and disease tendencies of the family lineage. This is the epigenetic landscape in Ayurvedic language.

Charaka’s Sharirasthana explicitly states that Beeja is shaped by Kshetra — the seed’s expression depends on the conditions of the field in which it develops. A seed of excellent genetic quality planted in depleted soil will produce a weak plant. A seed of modest genetic quality planted in rich, nourishing soil may produce remarkable fruit. The genetic potential is real; the field in which it expresses is equally real and equally determinative of outcomes.

Pitrujan Vikara — ‘disorders arising from ancestors’ — is a distinct disease category in Charaka that describes conditions originating not in the individual’s own experience but in the experiences of their parents or grandparents. The Charaka Samhita treats this as a clinical reality, not a metaphor: some conditions that present in an individual are rooted in ancestral history and require treatments that address not just the presenting symptom but the inherited tendency that produced it.

The practical implication of the Beeja-Kshetra framework is significant: if the ancestor’s Kshetra was compromised — by famine, by chronic stress, by poisonous environments — and that compromised state shaped the Beeja’s epigenetic expression, then treating the descendant requires modifying the Kshetra. Improving diet, reducing chronic stress, supporting metabolic function, and using Rasayana therapies to rebuild what was depleted across generations. Modern epigenetics agrees: epigenetic marks, unlike DNA mutations, are potentially reversible through appropriate environmental intervention. The field can be rehabilitated.

The epigenetic story of India’s famines has direct clinical and public health implications that are only beginning to be taken seriously.

South Asian metabolic vulnerability is not a personal failure. It’s not insufficient willpower about diet or exercise. It’s the biological legacy of historically inflicted starvation, running in bodies that survived by becoming extraordinarily efficient, and now operating in an environment for which that efficiency is metabolically costly. This reframing matters because it changes the intervention target: instead of simply telling South Asian individuals to eat less and move more (advice that ignores why their metabolism works the way it does), it points toward lifestyle approaches specifically calibrated for the inherited epigenetic configuration.

The good news in the epigenetics of famine is what Ayurveda’s Beeja-Kshetra framework always implied: epigenetic marks are not permanent fate. They respond to environmental intervention. Studies on exercise, dietary changes, and stress reduction have shown that specific epigenetic marks can shift in response to sustained lifestyle change. For South Asian populations with inherited famine-related metabolic configurations, the evidence converges on several specific strategies.

Caloric distribution rather than restriction: eating the same total calories in different patterns — larger meals earlier in the day when metabolic rate is higher, smaller or no meals in the evening — can significantly alter metabolic outcomes without reducing total food intake. This aligns with Ayurveda’s Dinacharya (daily rhythm) recommendations for the largest meal at midday.

Low glycemic index foods: since insulin resistance is the specific metabolic configuration inherited from famine epigenetics, foods that produce slower glucose responses reduce the demand on an already-taxed insulin system. Traditional Indian foods — rice replaced with millets, refined sugar replaced with jaggery, processed snacks replaced with whole legumes — are not just cultural preferences. They’re appropriate to the specific metabolic configuration of populations with this inherited epigenetic burden.

Chronic stress management: since cortisol and the HPA axis are themselves epigenetically modified by ancestral trauma (as Yehuda’s research showed), and since elevated cortisol drives insulin resistance, managing chronic stress is not optional for South Asian metabolic health. It’s a direct intervention in the epigenetic inheritance pathway.

And perhaps most importantly: understanding the history. The epigenetic burden of India’s colonial famines isn’t only biological. It’s also psychological and political. Communities that understand why their bodies work the way they do — that see their metabolic vulnerability as the physiological record of historical suffering rather than personal inadequacy — may be better positioned to make the sustained lifestyle changes that can shift the epigenetic landscape for the generations that follow them.

I want to say something about why this particular article feels personally important.

I’m an Odia, from a state that endured colonial-era famines, whose people’s resilience in the face of extraordinary historical hardship is something I’m deeply conscious of. The Odia community’s relationship to scarcity — a cultural thriftiness, a tendency to make extraordinary things from minimal resources — is something Odias often speak of with pride. It might also be, in part, the cultural expression of a metabolic configuration that the body developed in response to historical food insecurity.

This is one of epigenetics’ most profound implications: the body culture and the actual culture may be telling the same story. The wisdom traditions around food moderation, around finding satisfaction in simple meals, around not wasting a grain of rice — these might not only be cultural values. They might be the cultural encoding of a biological reality. The ancestors who survived the famines survived partly by developing bodies that needed less and stored more, and partly by developing cultures that valued what they had.

What the epigenetics research calls for, in the South Asian context, is not simply a clinical intervention. It’s a civilisational one: a reclaiming of traditional food wisdom, combined with a serious reckoning with the historical causes of the metabolic burden that the clinical numbers are now documenting. The connection between British colonial policy and the elevated rates of Type 2 diabetes and cardiovascular disease in South Asian communities worldwide is not metaphorical. The mechanism is known. The genes are methylated. The marks are detectable. History is still running in the body, and understanding that changes what we need to do about it.

• Reframe your metabolic story if you’re South Asian. If you’ve been told you have insulin resistance, elevated diabetes risk, or metabolic syndrome, consider this not as personal failure but as the body’s archive of historical survival. Then make the lifestyle choices that address the specific inherited configuration: low glycemic index foods, caloric distribution toward earlier meals, chronic stress management.
• Traditional Indian dietary patterns, eaten the traditional way, are closer to metabolically appropriate for the inherited South Asian epigenotype than modern urban South Asian diets. The gradual replacement of millets with refined rice and wheat, of traditional fermented foods with processed snacks, and of complex legume-based meals with fast food tracks almost perfectly with the trajectory of South Asian metabolic disease. The food wisdom of previous generations was, in part, the accumulated understanding of what worked for bodies with this epigenetic configuration.
• Ayurveda’s Rasayana concept — regenerative treatments that rebuild depleted Dhatus (tissues) across multiple generations — now has a specific scientific context: these are treatments that can potentially shift the epigenetic landscape that ancestral adversity created. Ashwagandha’s AMPK activation, Amalaki’s antioxidant protection against epigenetic damage, Brahmi’s support of neurological function compromised by inherited stress responses — these aren’t just wellness supplements. They’re targeted interventions in the Kshetra.
• If you’re a parent, the most important thing epigenetics tells you is this: your lifestyle choices during pregnancy and early childhood shape the Kshetra in which your child’s Beeja will express. Adequate nutrition, stress management, avoiding toxins, and cultivating genuine wellbeing during the prenatal period are not just personal health choices. They’re choices that will affect how your child’s epigenome is configured, and potentially how your grandchildren’s metabolic systems will function.
• Advocate for systematic epigenetic research on Partition survivors and their descendants, and on Dalit and marginalised caste communities. The research gap is significant. Understanding the epigenetic consequences of India’s specific historical traumatic events will produce more targeted public health interventions for South Asian communities globally.

Seven dimensions of the same profound insight. Epigenetics as the mechanism by which environment becomes biology. The Dutch Hunger Winter as proof that prenatal famine leaves heritable marks, still detectable 60 years later. India’s colonial famine history as one of the largest-scale instances of population-wide epigenetic trauma in human history. The specific genes — IGF2, LEP, ADIPOQ, INSR — whose methylation explains the South Asian metabolic phenotype that the clinical numbers have been documenting for decades. Rachel Yehuda’s Partition-relevant framework for understanding how psychological trauma transmits epigenetically alongside nutritional deprivation. Charaka Samhita’s Beeja-Kshetra-Pitrujan Vikara as the oldest systematic thinking about what we now call transgenerational epigenetic inheritance. And the clinical and personal implications for South Asian communities that carry this burden.

The body is an archive. It stores not just its own history but the history of the people who came before it, written not in words but in methyl groups at specific CpG sites, in the expression levels of genes that govern how energy is stored and spent, in the calibration of stress-response systems to adversity that hasn’t occurred for three generations.

Understanding this doesn’t excuse inaction. Epigenetic marks respond to environmental intervention. The Kshetra can be modified. But understanding it does change what kind of action is appropriate — and why South Asian metabolic health requires not just individual dietary discipline but a civilisational reckoning with the history that wrote these marks in the first place.
