Doctors say a return to traditional Nepali food could help tackle the country’s growing type 2 diabetes crisis. In Nepal, where diabetes medication is often unaffordable, one in five people over 40 now lives with the condition. Experts link the surge to western processed foods replacing traditional meals such as lentils and rice.
Pilot studies in Kathmandu and surrounding communities suggest the old diet can reverse diabetes in many cases. A small hospital study helped 43% of participants reach remission using a calorie-controlled version of dal bhat. A larger community trial has shown similar results, with about half of participants diabetes-free after four months and modest weight loss.
The research is led by University of Glasgow in partnership with Dhulikhel Hospital in Nepal. Professor Mike Lean said people of south Asian heritage develop diabetes at lower weights but also need to lose less to reverse it. Participants followed an eight-week low-calorie plan using local foods, then moved to a maintenance diet, supported by community groups and health volunteers.
Researchers blame rising diabetes rates on cheap, ultra-processed foods. A 2025 study found most packaged foods sold in Kathmandu exceeded World Health Organization limits for sugar, salt, or fat. Lean said the approach is simple, affordable, and more effective than medication. If successful, experts believe the model could help other countries facing similar diabetes epidemics.
