Study Summary

This trial tested new probiotics to help curb obesity: current standard of care for obesity and food addiction is difficult & lacks efficacy; bariatric surgery is an option but has barriers; new probiotics may provide an alternative way to reduce weight.

Who is the study for?
Adults aged 18-50 with a BMI of 25-40, who are not pregnant or nursing. Excluded if they have Type 1 diabetes, untreated thyroid disease, neurological issues, weigh over 400lbs, had certain abdominal surgeries, major medical conditions as determined by the study doctor, chronic pain or active psychiatric illness including eating disorders in the last two years.Check my eligibility

Why did patients apply to this trial?

Need to lose weight. I've lost weight and it all comes back. As I get older it's harder and harder to loose without starving myself.
PatientReceived 2+ prior treatments
I have tried to lose weight, but as I get older, it becomes harder and harder. I have lost weight in the past through diet and exercise, but it has been more difficult to accomplish as I age.
