Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The IWCR is a global scientific study aimed at better understanding the opportunities and barriers for reducing the prevalence of obesity by collecting information from people who have experience with weight management in their everyday lives. The investigators seek to gather information on a wide range of weight management experiences, ranging from weight loss and weight loss maintenance to weight gain and inability to lose weight.
