Using dietary intake data collected via the Automated Self\u2010Administered 24\u2010Hour Dietary Assessment Tool (ASA24), we examined (1) changes in caloric intake and the proportion of calories from UPFs from baseline to post\u2010intervention and (2) associations between these changes and weight loss, overall and adjusting for caloric intake.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Participants demonstrated reductions in calorie intake (\u2212461\u2009\u00b1\u2009931\u2009kcal\/day), UPF intake (\u22123.0%\u2009\u00b1\u20092.8% of total energy), and body weight (\u22127.2\u2009\u00b1\u20097.6\u2009kg) over the BWLI,\n                      <jats:italic>p<\/jats:italic>\n                      s\u2009&lt;\u20090.001.
