Table 3 Study 2: Identity and weight loss by weight loss categories

	Weight Loss Category
	Self-defined
	Successful	Regain		Unsuccessful
Exercise identity strength	0.90 (1.77)	− 0.18 (1.68)		− 0.28 (1.62)
Healthy-eater identity strength	1.56 (1.37)	0.57 (1.48)		0.51 (1.33)
Weight loss (%)	-19.09 (12.26)	-6.79 (11.67)		-5.21 (7.95)
Maintaining ≥ 5% WL, n (%)	268 (94%)	243 (51%)		27 (38%)
Not maintaining ≥ 5% WL, n (%)	17 (6%)	229 (49%)		45 (63%)
	Defined by Reported Weights
