Feasibility, Safety and Efficacy of a Predominantly Plant-based Diet in an Asian Population With Chronic Kidney Disease
Singapore40 participantsStarted 2026-04-01
Plain-language summary
This two-year follow up, single-center, open-label, feasibility study will recruit outpatients from the Renal Medicine Clinic at Changi General Hospital. Eligible patients with Stage 3 or 4 CKD will be assigned preferencebased to either a plant-based diet intervention (intake of at least 50% protein from plant sources) with regular dietitian counselling and follow up, or a control group receiving dietitian counselling for general CKD dietary advice without information on percentage of plant-based foods. Six monthly assessments will include estimated glomerular filtration rate (eGFR), serum potassium, nutritional markers, and other relevant biochemical parameters. Quality of life and dietary adherence will be evaluated through questionnaires and food frequency records. This study will evaluate primarily, the feasibility of a plant-based diet in the Singaporean context. Secondarily it will evaluate its safety in terms of incidence of hyperkalaemia, and benefit in terms of improvement in acidosis.
Other exploratory outcomes will include (1) preliminary efficacy of plant-based diets on CKD progression (measured by eGFR decline); (2) risk of nutritional deficiencies such as vitamin D, B12 and iron; and (3) impact on other biochemical parameters of CKD.

Inclusion criteria
. Age 21-79 (Only adults who can give consent will be recruited. Older adults aged 80 are not included to reduce the risk of confounding due to age-related frailty, sarcopenia and multimorbidity. Additionally, older adults may have different nutritional needs and energy requirements)
. CKD stage 3-4 (baseline eGFR 15-60ml/min/1.72m2 for the past 6 months)
. Willingness to see a dietitian and follow either a standard CKD diet or a predominantly plant-based CKD diet
. On maximum tolerated dose of ACE-inhibitors (Angiotensin converting enzyme inhibitors) or ARB (Aldosterone receptor blocker) as determined by Renal Physician in charge
. Able to provide informed consent
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
