Because Lwt/+ animals weigh less than wild types, food and water consumption was monitored for 19 days beginning at approximately postnatal day 80 (P80) and followed by body composition analysis at P100. Analysis of age adjusted data (Model 1, see Materials and Methods) indicate that Lwt/+ mice are shorter in length and weigh less than +/+ mice. In addition, Lwt/+ mice consume similar amounts of food and water, yet accumulate less fat than +/+ mice (Table 1).
