Who could benefit from this research

Could help

Ideal candidates are adults with obesity and/or type 2 diabetes who have fractures and are potential beneficiaries of improved bone healing.

Less likely to help

Patients without obesity/diabetes or those with fractures not prone to impaired healing may not benefit.

What this research studies

This project uses a obesity/diabetes mouse model to see how intermittent fasting affects bone repair after fracture, focusing on inflammatory and repair-phase processes and the cells that form bone. Researchers will look at how feeding patterns alter the callus and its gene activity, and whether probiotics can mimic the benefits seen with fasting. They will also test whether blood plasma from people practicing intermittent fasting can influence human bone marrow cells in the lab. The goal is to identify mechanisms by which the gut microbiome supports bone healing and to translate findings toward human treatment strategies.

Why it matters

Potential benefit: If successful, the work could lead to dietary strategies or probiotic approaches that improve fracture healing in people with obesity and diabetes.

How similar studies have gone: Earlier studies in mouse models showed improved healing with intermittent fasting and microbiome changes, with some translation potential to human cells.
