In the event of a tie between two or more participants in either Percentage of Weight Lost or Total Weight Lost, body fat percentage will be used to break the tie for the weight loss challenge and for the Muscle Mass challenge percentage of change in the muscle mass. Sponsor staff will determine, in its sole discretion, which participant had greater body fat percentage reduction from initial to final check-in as detailed on the InBody scan.
