It is one of the most consistent experiences in the Nigerian diaspora. You arrive in the UK, the US, or Canada. Within 12–18 months, you have gained 5, 10, sometimes 15 kilograms. Your clothes no longer fit. Your energy levels have changed. And you cannot quite understand why — because you are still eating Nigerian food, the same food you ate at home without any weight problems.
This experience is so common it has become a running joke in diaspora communities. But the weight gain is real, and the reasons behind it are specific and understandable. More importantly, they are fixable.
Reason 1: The Portion Size Trap
In Nigeria, most people eat from shared pots and serve themselves according to hunger. Portions are naturally regulated by social eating, the effort of cooking, and the cost of food. In the diaspora, food is often eaten alone, in front of a screen, from a full plate that was served without thought.
Research on eating behaviour consistently shows that people eat more when eating alone, when distracted, and when food is pre-plated in large portions. The Nigerian diaspora experience combines all three factors. The result is that the same jollof rice you ate in Lagos — perhaps 200–250g per serving — becomes a 400–500g serving in London, simply because the plate is larger and there is no social regulation.
Reason 2: The Sedentary Shift
In Nigeria, daily life involves significantly more incidental physical activity than life in the UK or US. Walking to the market, standing in queues, manual work, and the general physical demands of daily life in a developing economy all contribute to calorie expenditure. In London or Houston, you drive everywhere, sit at a desk for eight hours, and take a lift instead of stairs.
This shift in activity level can reduce daily calorie expenditure by 300–500 calories. If eating habits remain the same, that deficit accumulates into weight gain over months and years — even if the food itself has not changed.
Reason 3: The Stress Eating Response
Migration is stressful. Navigating a new country, building a career, managing finances, and maintaining relationships across time zones creates chronic low-level stress that many diaspora Nigerians manage through food. Nigerian food, in particular, carries powerful emotional associations — it is comfort, home, and identity all at once. Eating a plate of jollof rice or a bowl of egusi soup is not just nutrition; it is an act of cultural reconnection.
This is not a character flaw. It is a well-documented psychological response to displacement. But it does mean that food consumption in the diaspora is often driven by emotional need rather than physical hunger, leading to higher calorie intake than the body actually requires.
Reason 4: The Hidden Calories in Diaspora Nigerian Cooking
Diaspora Nigerian cooking is often richer than home cooking — more oil, more seasoning, larger quantities of protein — because food has become a way of recreating the abundance and celebration of home. A pot of egusi soup cooked in Lagos might use three tablespoons of palm oil. The same pot cooked in London might use five or six, because the cook is trying to recreate the flavour memory of their mother's cooking.
This richness is understandable and culturally meaningful. But it adds 200–400 extra calories per pot, distributed across every serving.
The Solution: Track, Adjust, Enjoy
The solution is not to stop eating Nigerian food. It is to understand the calorie content of what you are eating and make small, targeted adjustments. Reduce oil by one tablespoon per pot. Reduce swallow portions from 400g to 200g. Walk for 30 minutes three times a week. These changes, consistently applied, are enough to reverse diaspora weight gain without abandoning the food that connects you to home.
