A method for weight loss includes collecting a fee from each participant in a group of participants who desire to lose an amount of weight within a determined amount of time. Participants are weighed at the beginning of the determined amount of time. The participants are allowed to engage in activities that would allow weight loss. The participants are weighed after a determined amount of time, and the change in weight of the individual participants is calculated. A determination of which participants have lost the desired amount of weight within the determined amount of time is made. A portion of the collected fees is distributed to the participants who have lost the desired weight. The distributed portion of the collected fees can include travel vouchers, gift certificates or other reward structures.
