What the research says
1 study reviewedSupporting (1)
Randomized Controlled TrialHuman2025
People with a type of gut inflammation who ate a very low-calorie, plant-based diet for a few days each week felt better, needed fewer steroid drugs, and had less inflammation — even though they didn’t lose weight. This suggests fasting-like eating may help them, even if they’re obese.

That doesn't mean it's settled — it just means no study has tested the opposite.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.
When calorie intake drops and carbohydrates are severely limited, the body switches to burning fat for fuel, producing a molecule called beta-hydroxybutyrate. This molecule triggers a cellular cleanup process that removes damaged parts and strengthens the gut lining. A stronger gut barrier prevents bacteria from leaking into the bloodstream, which reduces immune activation and lowers inflammation throughout the body. This leads to fewer symptoms and less need for anti-inflammatory drugs.
