How upper‑body versus lower‑body fat affects diabetes and metabolism

Regional Fatty Acid Metabolism In Humans

NIH-funded research Mayo Clinic Rochester · NIH-11352571

This project tests whether losing upper‑body (visceral) fat improves blood sugar control and overall metabolism in adults with Class I obesity.

What this research studies

You would follow an energy‑deficit program designed to lose about 8 kg of body fat while researchers track changes in your metabolism. They will take blood tests and small fat biopsies from both upper‑body (including visceral) and lower‑body fat to measure how fat is stored and released. The team will also study how meal fats are handled and look at enzyme activity and gene signals in those fat depots. Results will be compared before and after weight loss and between premenopausal and postmenopausal women.

Who could benefit from this research

Good fit: Adults aged 21 and older with Class I obesity who are willing to follow a supervised weight‑loss program and undergo blood tests and small fat biopsies would be ideal candidates.

Not a fit: People without obesity, children, or anyone unwilling or medically unable to undergo biopsies and multiple clinic visits would likely not benefit from participating.

Why it matters

Potential benefit: If successful, this work could explain why upper‑body fat raises diabetes risk and point to more targeted weight‑loss strategies or treatments.

How similar studies have performed: Previous research shows visceral fat is linked to insulin resistance and that weight loss improves metabolism, but the detailed depot‑specific mechanisms and meal‑fat handling remain incompletely understood.
