Great question! We consider you to have succeeded in your challenge if you report that you met your goal and verify this result with either photo or in-person evidence.
At the end of your challenge, you will be asked to submit a Final Report on your weight-loss or smoking status. If you report that you met your goal, we will ask for additional verification.
Most people will be asked to verify their Final Report by submitting a photo from home. Some people will also be asked to verify their success in-person at Quest Labs.
If your verified results match your report, your challenge result will be considered successful. If your verification does not match your reported result, or if you do not complete verification, your challenge result will be considered unsuccessful.
