  • *If percentages do not reach 100% that is due to rounding.

  • †Weight change from previous year to the current year.

  • ‡LTWL was calculated by subtracting the reported weight 1 year ago or current weight (the higher of the 2), by the reported maximum weight, and then multiplying by 100 to receive a percentage.

  • §HEI-2015: indicates adherence to Dietary Guidelines for Americans. The score ranges from 0 to 100 with the highest score indicative of complete compliance with the guidelines. Kcal- total daily calories.

  • ¶Smoking: current smoking status was based on blood cotinine levels using an established cut-off of 3.08 ng/mL.

  • **Moderate alcohol: participants were defined as meeting moderate drinking guidelines, if consuming one alcoholic drink or less per day for women or two drinks or less daily for men.

  • ††MET minutes per week for leisure time physical activity. Meeting physical activity guidelines refers to ≥500 MET min/week.

  • BMI, body mass index; HEI, Healthy Eating Index; LTWL, long-term weight loss; MET, metabolic equivalent of task.
