Read our Obesity research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
The LightBAR trial is testing whether an intensive weight loss program can work as well as weight loss surgery for people with severe obesity. The program includes meal replacements, behavioral support, and weight loss medication over two years, and is being compared directly to two common types of weight loss surgery. This trial will help doctors and patients understand which approach works better for different people.
Weight loss surgery is often recommended for people with severe obesity, but it's invasive and carries surgical risks. This trial exists to see whether a carefully designed non-surgical program—combining diet, counseling, and medication—might be just as effective, giving patients another safe option to choose from.

If you join this trial, you will be randomly assigned to either the intensive weight loss program or weight loss surgery. The program lasts two years and has three phases: a 12-week intense phase using meal replacements and medications, a 20-week transition phase reintroducing regular foods and adding exercise, and a maintenance phase where you continue healthy eating and activity with ongoing support. If you are assigned to surgery, you will receive either gastric bypass or sleeve gastrectomy. Throughout the two years, you will have regular clinic visits to monitor your progress, health, and weight.
