The Study
Efficacy of a Low-Purine, Energy-Restricted and Balanced Diet on Hyperuricemia and Metabolic Profiles in Gout Patients: A Randomized Controlled Trial
This study is like a fair test where one group ate a special diet and another group got basic advice. The group with the special diet had lower uric acid and lost some belly fat. But we can't say the diet 'cured' gout—just that it helped improve some numbers in this short test.
Analysis score
Maximum 90 for a randomized controlled trial.
Where the score came from
This study tested if a special diet that cuts out meat and junk food, while eating more veggies and eggs, helps gout patients feel better.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes—this drop in uric acid is enough to help most patients reach the target level to prevent gout flares, and losing belly fat reduces long-term health risks.
- 2After 42 days, uric acid dropped by 112.4 μmol/L, belly fat shrank by 12.1 cm², and BMI fell by 0.50 kg/m²—all without losing muscle.

In men with gout taking febuxostat, a 42-day low-purine, calorie-restricted diet lowers blood uric acid by 112.4 μmol/L on average through increased uric acid excretion and reduced dietary purine intake, resulting in a higher proportion of patients reaching uric acid levels below 360 μmol/L.
In men with gout, following a low-purine, calorie-restricted diet for 42 days results in a 0.87% increase in the amount of uric acid removed by the kidneys, which directly explains the decrease in blood uric acid levels.
In men with gout, following a low-purine, calorie-restricted, and balanced diet for 42 days lowers blood triglyceride levels by 0.40 mmol/L without affecting fasting glucose or total cholesterol.
In men with gout, following a low-purine, calorie-restricted, and balanced diet for 42 days results in a reduction of visceral fat by 12.1 cm² and a decrease in body mass index by 0.50 kg/m², without loss of muscle mass.
In men with gout, following a low-purine, calorie-restricted, and balanced diet for 42 days increases kidney filtration rate by 3.8 mL/min/1.73m² and lowers blood creatinine by 4.2 μmol/L, showing improved kidney function without changes in blood pressure or hydration levels.
Reducing calorie intake lowers the amount of uric acid in the blood because less purine is consumed in the diet.
