Traditional Nepali Diet Could Combat Diabetes Epidemic, Research Indicates
In Nepal, where type 2 diabetes affects one in five individuals over the age of 40, a return to traditional foods like dal bhat—a staple dish of lentils and rice—could help reverse this growing health crisis. With diabetes medication largely unaffordable in the country, experts are turning to community-based dietary interventions as a viable solution.
Pilot Study Shows Promising Results
A pilot study conducted in Kathmandu involved 70 hospital patients with long-established diabetes. By placing them on a calorie-controlled traditional diet, 43% achieved remission. An ongoing trial with 120 participants in rural and suburban areas has shown similar success, with around half becoming diabetes-free after four months and an average weight loss of only 4-5kg.
Dr. Ashish Tamang, a resident doctor in Kathmandu, emphasized the broader impact, stating, "For many families, diabetes is not just a medical condition, but a long-term social and economic burden."
Genetic Factors and Dietary Adjustments
Professor Mike Lean, a diabetes and human nutrition expert from the University of Glasgow, explained that people of Asian descent are genetically predisposed to type 2 diabetes, requiring less weight loss to reverse the condition compared to Western populations. In the UK, patients might need to lose 10-15kg, whereas in Nepal, only about half that amount is necessary.
The dietary plan developed for the study includes:
- A weight loss phase of 850 calories per day for eight weeks, featuring meals like dal bhat.
- A maintenance phase with a higher-calorie version of the same traditional diet.
- Use of local, affordable ingredients to ensure accessibility.
Community-Led Intervention Strategy
Participants received measuring tools and diet plans to control portion sizes, along with regular support group sessions. The approach leverages female community health volunteers, aiming to deliver interventions without reliance on doctors or hospitals. Trial documents describe the plan as emphasizing disciplined eating patterns and avoiding processed Western foods high in fat and sugar.
A 2025 study found that 87% of packaged foods in Kathmandu shops exceeded WHO thresholds for sugar, fat, and salt, highlighting the need for dietary change.
Funding and Future Prospects
Originally funded by the UK government but cut, the expanded study has received £1.78 million from the Howard Foundation. It will continue to explore how traditional diets can prevent diabetes in high-risk individuals and create educational materials on diabetes drivers. Professor Lean attributes rising diabetes rates in Nepal to the influx of Western junk foods and reduced physical activity due to technological advances.
He noted, "It's not rocket science, but it's way more effective than any drug or medicine." Officials from neighboring countries have expressed interest, suggesting that if successful in Nepal, this approach could be applied elsewhere.
