Summary

This study compares two pre-surgery diets for people scheduled for bariatric surgery: ready-to-eat meals versus standard liquid meal replacements. The goal is to see which diet is easier to stick to, measured by blood ketone levels and meal logging. About 140 adults will participate, and the study also tracks satisfaction and weight changes.

What this could mean

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

Active substance: Very Low Calorie Diet Ready-to-eat (VLCD RTE) meals
What this could lead to: If successful, this could offer a more convenient and palatable pre-surgery diet option, potentially improving weight loss outcomes before bariatric surgery.
What could go wrong: This is a small, early-stage trial focused on compliance, not long-term outcomes. The ready-to-eat meals may not be more effective than the standard liquid diet, and individual results may vary.
