Summary

This study investigates whether a special cooking oil called diacylglycerol (DAG) oil can improve thinking skills and reduce body weight in adults aged 45 to 75 who have both obesity and mild cognitive impairment. Participants replace their usual cooking oil with either regular rapeseed oil or DAG oil for six months. Researchers will measure changes in cognitive function, body weight, and body fat to see if the DAG oil offers added benefits.

What this could mean

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

Active substance: Diacylglycerol (DAG) oil
What this could lead to: If it works, this could point toward a simple dietary change to help manage both weight and early memory decline.
What could go wrong: This is a small, early-stage trial. The oil may have no meaningful effect on cognition or weight, and results may not apply to everyone.
