Summary

This trial is investigating how fat is stored in organs, and why this impacts some people's health more than others. The findings could lead to better treatments for diabetes and cardiovascular disease.

Who is the study for?
This trial is for adults with obesity, some of whom may be scheduled for bariatric or gallbladder surgery. Participants should have a BMI ≥30 kg/m2 and meet certain health criteria like normal blood sugar levels and liver fat content. It's not open to those with other liver diseases, alcohol abuse history, severe hypertriglyceridemia, recent cancer diagnosis, or who are pregnant.
What is being tested?
The study investigates how the body stores fat in organs like the liver and its impact on health. The focus is on understanding obesity-related inflammation and cardiometabolic risk which could inform future treatments for diabetes and heart disease.
What are the potential side effects?
Since this trial involves weight loss as an intervention rather than medication or medical procedures, side effects might include typical dieting symptoms such as fatigue, hunger pangs, mood swings, muscle cramps from exercise if applicable but no specific medicinal side effects.
