Summary

This study is testing whether eating a low-glucose, high-fat (ketogenic) diet for 7 days before a PET scan can make the scan better at finding a specific type of slow-growing lung cancer called lepidic-predominant adenocarcinoma. This cancer often doesn't show up well on standard PET scans. About 30 adults with a suspicious lung nodule will follow the diet and then have a PET scan. The results will be compared to the actual diagnosis from a biopsy to see if the diet improves accuracy.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
ketogenic diet
What this could lead to
If it works, this could make PET scans more accurate for a type of lung cancer that is often missed, leading to earlier diagnosis.
What could go wrong
This is a very small, early study with only 30 people. The diet is strict and may be hard to follow, and it's not yet known if it will actually improve detection in practice.
