Weight loss and regain dynamics during an outpatient lifestyle intervention. A, left: a typical outpatient weight loss program results in the characteristic BW change trajectory, where the symbols are identical to those in Fig. 3. A, right: predicted free-living EI and TEE underlying the observed BW loss and regain trajectory. B: the model predicted that maintenance of lost BW and FM (left) would have been achieved if the EI over the last 2 yr had been decreased by 170 kcal/day. C: had the initial reduction of EI been sustained for the 3-yr period, the model predicted a progressive decrease of BW and FM shown at left and the corresponding TEE changes shown at right. Data are presented as means ± SD.
