Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting

Summary

This study looks at how lean pork loin and plant-based protein affect muscle building and blood sugar control in adults with prediabetes. Twenty participants aged 40-65 will eat prepared meals for three days. Researchers will measure muscle protein synthesis and glucose levels to see if one protein source is better.

What this could mean

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

Active substance
lean pork loin and plant-based protein
What this could lead to
If successful, this could show that lean pork helps maintain muscle and control blood sugar better than plant protein in people with prediabetes.
What could go wrong
This is a very small, short-term study (20 people, 3 days of meals). Results may not apply to real-world diets or long-term health.
