Can a meatless keto diet cut inflammation and oxidative stress?
NCT ID NCT05558488
First seen Sep 24, 2026 · Last updated Sep 25, 2026 · Updated 1 time
Summary
Researchers are testing whether a meatless ketogenic diet rich in omega-3 fats can reduce body fat, oxidative stress, and inflammation in healthy adults. Fourteen participants follow a high-fat, very low-carbohydrate diet with reduced calories for a set period. The study measures body composition, blood and urine markers like TMAO and ketones, strength, and immune response to see how the diet affects the body.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a meatless ketogenic diet rich in omega-3 fats
- What this could lead to
- If it works, this could point toward a diet strategy that lowers inflammation and oxidative stress while preserving strength.
- What could go wrong
- This is a very small study of 14 healthy adults, so any changes may not apply to others. The diet is restrictive and may be hard to follow.
