Adults aged 18\u201360 years with self-reported office-based employment and available baseline and follow-up weight records were included. Participants voluntarily selected one of six dietary pattern groups: 16:8 time-restricted eating, 5:2 intermittent fasting, flexitarian diet, moderate-to-high protein diet, calorie-restricted balanced diet (CRD), or Dietary Approaches to Stop Hypertension (DASH). Within-group BMI changes were tested using paired t-tests, and between-group BMI changes were assessed using analysis of covariance (ANCOVA) adjusting for age, sex, baseline BMI, and follow-up duration.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 5066 participants were included (mean age 31.53\u00b1 10.69 years; 94.20% female), and the CRD (39.42%) were the most commonly selected dietary patterns, whereas the flexitarian and DASH groups were substantially smaller. The median follow-up duration was 19 days.

Because dietary pattern selection was voluntary and follow-up was short, the findings should be interpreted as observational associations rather than evidence of comparative dietary effectiveness.
