If you’ve ever wondered why an apparently “normal” Indian diet of rice, rotis, and sabzi often seems to fuel fat gain and health issues faster than expected, you’re not alone.
There’s a story here that’s partly genetic, partly dietary, and mostly misunderstood until now.
Let’s explore it in a way that’s simple, relatable, and backed by evidence.
1. A Carb-Heavy Indian Plate Is Now the Norm
Recent nationwide research shows that Indian diets are uniquely carbohydrate dominated much more than global averages be it east, west north or south of India.
In fact, the Indian Council of Medical Research (ICMR) found that about 62% of daily calories in Indian diets come from carbohydrates, especially white rice, wheat and added sugar. This carbohydrate load is linked with higher risks of obesity, prediabetes, and diabetes.
Contrast that with many Western eating patterns where protein and healthy fats make up a greater share of daily energy, and you start to see why Indian bodies may respond differently.
2. Our Evolutionary “Blueprint” Makes Us Carb-Sensitive
Scientists use the term “insulin resistance” to describe how our body’s cells stop responding well to insulin, the hormone that helps move glucose from the blood into cells.
Asian populations, including Indians, often show higher baseline insulin resistance even at relatively normal body weight compared with some other populations. https://pubmed.ncbi.nlm.nih.gov/19675375/
While sweeping claims like “thrifty genes” are still hypotheses, research does show that South Asians tend to have:
- higher post-meal insulin levels.
- higher plasma triglycerides.
- metabolic responses that favour fat storage after carbohydrate intake.
when compared to some other ethnic groups.
This doesn’t mean Indians are under threat or “genetically doomed” but it does mean our metabolism reacts differently to large carbohydrate loads than the metabolism of some other populations.
3. Lower Muscle Mass plus Higher Visceral Fat = Bigger Metabolic Challenge
A surprisingly common pattern in Indians is that even those who are not overtly obese are having:
- lower skeletal muscle mass.
- higher central (visceral) fat.
Studies show that many non-obese Indians have higher body fat and lower muscle mass, especially in the liver and muscles. This is a key driver of insulin resistance and weight gain, even in people with normal BMI.

This pattern is crucial: Muscle is a major “glucose sink.”
More muscle means more room to clear sugar from your blood without overworking insulin.
Less muscle means excess glucose stays in the bloodstream, signalling the body to store it as fat.
4. Carbs Trigger a Chain Reaction in Metabolism
Here’s the simple physiology:
- You eat carbs, leading to blood glucose rises, which causes insulin release.
- In a high carb context (lots of rice, wheat, sugars, packaged food etc), this process happens frequently throughout the day.
- High insulin tells the body to store fat and not burn it.
Over time, this leads to:
✔ Higher fasting insulin.
✔ Sluggish glucose metabolism.
✔ More fat storage especially around the belly.
✔ Faster weight gain even with “normal” calorie intake.
That’s how a high carb diet can accelerate metabolic problems in Indians.
5. This Isn’t Just “Calories In, Calories Out”
Yes, energy balance matters.
But for many Indians, the quality and proportion of calories especially, the high carbohydrate share amplifies metabolic problems.
The ICMR/INDIAB research showed that replacing even a small portion of carbs with higher-quality proteins (like dairy, pulses, eggs, fish) could cut diabetes risk substantially.
That tells us this isn’t just about eating less it’s about eating differently in a way that aligns better with how Indian metabolism functions.
6. Genes and Environment Both Matter and the Diet Pulls the Trigger
It’s tempting to blame genes alone but the picture is nuanced:
- Genetic predispositions can influence how your metabolism reacts to food.
- But lifestyle and diet are the actual triggers that flip metabolic switches.
One endocrinologist pointed out that certain gene variants linked to visceral fat and insulin resistance (e.g., TCF7L2, PPARG, FTO) are relevant in South Asians, making them more sensitive to high-glucose diets.
The genes don’t force disease; they make certain dietary patterns more consequential.
7. What This Means for You (Real-World Takeaway)
If your metabolism is carb sensitive:
✔ Building lean muscle through strength training and protein-rich food helps clear glucose and reduces fat storage.
✔ Reducing overall carbohydrate load especially, the refined carbs this eases the insulin burden.
✔ Balancing your plate with protein, fibre, and healthy fats gives your body better tools to regulate blood sugar.
This is not about demonising food you love; it’s about understanding what works with your metabolism based on evidence and lived experience not just calories.
Conclusion: It’s Biology, But Not Destiny
Indians tend to gain weight faster on high-carb diets not because of individual weakness, but because of a metabolic and dietary mismatch:
🔹 High dietary carbohydrate proportion.
🔹 Lower muscle mass and higher visceral fat.
🔹 Genetic predispositions that make our insulin response more sensitive.
Understanding this gives you a scientific solution, ones that respects culture, supports health, and doesn’t blame the individual.
