Weight Loss Study

Study participants are needed for a research study to test an established nutritional shake on weight loss in healthy overweight individuals between the ages of 25 and 50.  Participants will visit our clinic (downtown Toronto) to be screened, and if eligible, on 5 more occasions over a 3 month period.  Participants will receive $750 if they successfully complete the study.
