Most religions have proscriptions of prescriptions regarding the consu
mption of food; yet little attention has been given to the relationshi
p between religion and body weight. This paper explores two major ques
tions: (1) Is religion related to body weight, especially the prevalen
ce of obesity? (2) Does religion intensify, mitigate, or counterbalanc
e the effects of body weight on well-being? Two data sources are used
in this exploratory study. First, state-level ecological data on relig
ion and body weight show that body weight is somewhat higher in states
with a higher proportion of church and temple members. Second a natio
nal sample of adults surveyed in 1986 is used for the bulk of the anal
ysis is (N=3,497). Three dimensions of religiosity (practice, identity
, and comfort) and three measures of body weight (underweight, overwei
ght, and overall body mass) are examined. Religious practice is associ
ated with all measures of well-being and generally acts to counterbala
nce the negative effect of body weight on well-being. Obese persons ar
e more likely to be depressed and have lower levels of health satisfac
tion despite their higher levels of religious practice.
