Why NRIs Gain Weight Abroad (And How to Fix It)

"I hear it from almost every NRI client: 'I moved abroad, my life got busier and in some ways healthier, and yet I gained weight.' It is not in your head, and it is not laziness. There are specific, fixable reasons Indians gain weight after moving abroad - and once you understand them, the fix is very doable." - Dt. Trishala Goswami, MSc Clinical Nutritionist, Certified Nutrigenomics Specialist

If you moved from India to the US, UK, Canada, Australia, or the Gulf and watched the kilos creep on, you are in very large company. NRI weight gain is one of the most common things I help with - and it has clear causes that have nothing to do with willpower. Here is what is really going on, and how to turn it around with Indian food.

1. South Asian genetics

This is the big one. South Asians are genetically predisposed to insulin resistance and tend to store fat around the abdomen at lower body weights than Western populations. The same BMI carries more metabolic risk for an Indian than for the average local. So when your diet and activity shift after moving, your body responds more readily with weight gain and blood-sugar trouble. We explain the mechanism in PCOS and insulin resistance, and the gene side in nutrigenomics explained.

2. Portion sizes and the food environment

Western food environments are built for overeating - larger portions, bottomless refills, cheap calorie-dense food, and ultra-processed snacks everywhere. Even without trying, your daily intake quietly rises. Restaurant and takeout portions abroad can be double what you would serve at home.

3. Hidden liquid calories and processed food

Coffee-shop culture, sodas, juices, alcohol, and packaged snacks add hundreds of calories that do not register as "meals." For many NRIs, the move abroad comes with a daily latte and weekend takeout habit that adds up fast.

4. Less incidental movement

Life in India often involves more incidental activity - walking to the market, stairs, general bustle. Car-dependent suburbs and desk jobs abroad can sharply cut your daily steps without you noticing.

5. Stress, sleep, and deficiency

The stress of relocating, building a life, and often working long hours raises cortisol, which drives belly fat and cravings. Add the common NRI deficiencies - vitamin D from low sunlight and B12 from vegetarian eating - and your metabolism and energy take a further hit.

The fix: rebalance, don't abandon, Indian food

Here is the good news. You do not need to give up Indian food or live on salads. The fix is to rebalance the Indian plate and adjust to your new environment:

This is exactly why calorie counting alone fails for Indian diets - the composition and structure of your plate matter more than obsessive tracking.

You're not starting from scratch

The most reassuring thing I tell NRI clients: your weight gain abroad is a logical response to a changed environment and a South Asian body - not a personal failure. Change a handful of the right things, consistently, and it reverses. Indian food, rebalanced and adapted to where you live, is the most sustainable tool you have.
