Yes, researchers want participants for vegan diet research in 2026. The main opening is Plant Your Health, a 12-month trial of vegetarian and vegan diets for long-term health. A vegan diet means eating no animal products, including meat, fish, dairy and eggs. Plant Your Health compares strict vegan eating with vegetarian eating and a usual diet.

Who can join the Leicester trial?
The University of Leicester and Leicester Diabetes Centre are recruiting 450 volunteers for the year-long study, according to the Leicester Diabetes Centre announcement. The trial focuses on adults whose current eating leaves room for a clear change.
Check these basic requirements: Participation also requires living near Leicester. Volunteers attend three visits at the Leicester Diabetes Centre.
- Age 18 to 50
- Living with overweight or obesity
- Currently eat meat at least five days per week
- Willing to change diet for one year
What will participants do for 12 months?
Volunteers are assigned at random to one of three eating patterns for a year. One group follows vegetarian eating without meat or fish but with dairy and eggs. Another follows strict vegan eating.
The third continues its usual diet. Researchers track health and environmental effects across the groups. Measures include LDL-cholesterol, blood pressure, blood glucose, body composition, psychological wellbeing and dietary carbon footprint. The Leicester team says the work aims to inform public-health policy and dietary guidelines.
What support and payments are offered?
Enrolled volunteers receive dietitian guidance, cooking classes and in-depth health checks. They also receive supermarket vouchers during the study.
The study page lists a £50 thank-you voucher plus up to £15 per visit for travel, according to the Leicester Diabetes Centre study page. That package matters for people weighing a full year of food shopping, travel and clinic time.
Is there a global vegan survey too?
Yes. The independent Huge Vegan Survey opened globally in April 2026 for adults who identify as vegan or plant-based. It reached 10,000 respondents by October 1, 2026 and stayed open for additional weeks, according to the UnchainedTV report.
That survey is different from the Leicester trial. It collects responses online rather than assigning a diet or giving clinic care. People who cannot join the year-long trial can still contribute evidence through that survey while places remain.
How do you apply?
Interested people apply directly by emailing [email protected]. Include your age, location, current meat eating and ability to attend three Leicester visits.
