Patients and practitioners are confronted with mixed messages about th
e value of obesity treatment. Serious treatment is supported by the me
dical consequences associated with obesity. Abandoning current treatme
nt is suggested by a lack of long-term efficacy. We suggest a reevalua
tion of the assumptions and practices of obesity treatment. Empirical
support for changing our current thinking about obesity treatment is p
resented. This change in philosophy and practice is based on five fact
ors: (a) targeting those at highest medical risk; (b) acknowledging th
e role of biological factors in treatment goals; (c) addressing the ps
ychological heterogeneity of obese persons; (d) setting reasonable exp
ectations for long-term outcome; and (e) assessing the benefits and ri
sks of weight loss. It is suggested that these factors promote a more
realistic view of obesity treatment and allow practitioners and client
s to make more informed decisions about the benefits and risks of trea
tment.
