This week marks the 15th anniversary of Joslin’s Why WAIT program, one of the longest-running programs in Joslin’s history. Why WAIT started on September 28th, 2005 as the world’s first, multidisciplinary weight management program for patients with type 1 and type 2 diabetes and obesity.

In fact, a 10-year follow up of Why WAIT participants showed a maintenance of weight loss of 6.9%, with around 53% of participants achieving an average of 9% weight loss.

We thank our Education team who make this program possible and who have worked out a virtual version of this normally onsite program during the pandemic. And we thank all of our participants over the years for their hard work. Our biggest reward is seeing our patients happy with their achievements in losing weight and controlling their diabetes.
