An intra-oral device for weight management includes a carrier having a resiliently deformable protuberance on its outer surface. The protuberance may comprise a bite-pad having a height that varies along its length, with the apex being aligned with a first molar of a dental arch of the user. The protuberance may comprise a planar ridge structured and arranged to increase resistance to lateral movement of the user's jaw during a normal chewing cycle. Multiple resiliently deformable protuberances may include a bite-pad and a planar ridge on a buccal side of the bite-pad. Either or both of the bite-pad and planar ridge may be provided with an uneven, textured exterior surface. A method for promoting weight management may include positioning the carrier over an arch of teeth of the user instead of eating. The method may further include chewing on the carrier so as to deform the protuberance.
