Deprivation, food craving and restraint

[Guest guest]

Hi All,

A new study examines individual differences in wanting desirable food and

eating.

Whether you can CR easily may affect how much you are attracted to tasty foods,

it

seems.

See the pdf-available article described below.

Polivy J, J, Herman CP.

The effect of deprivation on food cravings and eating behavior in restrained and

unrestrained eaters.

Int J Eat Disord. 2005 Oct 31; [Epub ahead of print]

PMID: 16261600

OBJECTIVE: The relation between being deprived of a food and intake and craving

for

that food was investigated in restrained and unrestrained eaters. METHOD: For 1

week, 103 female undergraduate students were assigned to be chocolate deprived,

vanilla deprived, or nondeprived. Only chocolate deprivation was expected to

elicit

cravings, as chocolate is not easily substituted, whereas vanilla is. RESULTS:

The

main effect of chocolate deprivation on consumption was qualified by an

interaction

with restraint. Chocolate-deprived restrained eaters consumed more chocolate

food

than did any other group. Restrained eaters experienced more food cravings than

did

unrestrained eaters and were more likely to eat the craved food. Moreover,

restrained eaters deprived of chocolate spent the least time doing an anagram

task

before a " taste-rating task " in which they expected that chocolate foods might

be

available. CONCLUSION: Converging measures of craving indicate that deprivation

causes craving and overeating, but primarily in restrained eaters.
