Maintainers were asked whether they were currently watching their diet to maintain their weight. Percentages are for all maintainers who reported they were watching their diet.
* Statistically significant using the Bonferroni correction.
†Chi-square tests for significant differences between Maintainers (initial weight loss) and Regainers. P-values were corrected for multiple comparisons using the Bonferroni method.
Note: Respondents selected all applicable categories so responses do not total to 100 %. Of those who changed their diet, 78 % changed both diet and exercise and 22 % changed only diet.
