Katherine Hepburn famously said of her slim physique: "What you see
before you is the result of a lifetime of chocolate." New evidence
suggests she may have been right.
Beatrice Golomb, MD, PhD, associate professor in the Department of
Medicine at the University of California, San Diego, and colleagues
present new findings that may overturn the major objection to regular
chocolate consumption: that it makes people fat. The study, showing that
adults who eat chocolate on a regular basis are actually thinner that
those who don't, will be published online in the Archives of Internal Medicine on March 26.
The authors dared to hypothesize that modest, regular chocolate
consumption might be calorie-neutral -in other words, that the metabolic
benefits of eating modest amounts of chocolate might lead to reduced
fat deposition per calorie and approximately offset the added calories
(thus rendering frequent, though modest, chocolate consumption neutral
with regard to weight). To assess this hypothesis, the researchers
examined dietary and other information provided by approximately 1000
adult men and women from San Diego, for whom weight and height had been
measured.
The UC San Diego findings were even more favorable than the
researchers conjectured. They found that adults who ate chocolate on
more days a week were actually thinner -- i.e. had a lower body mass
index -- than those who ate chocolate less often. The size of the effect
was modest but the effect was "significant" -larger than could be
explained by chance. This was despite the fact that those who ate
chocolate more often did not eat fewer calories (they ate more), nor did
they exercise more. Indeed, no differences in behaviors were identified
that might explain the finding as a difference in calories taken in
versus calories expended.
"Our findings appear to add to a body of information suggesting that
the composition of calories, not just the number of them, matters for
determining their ultimate impact on weight," said Golomb. "In the case
of chocolate, this is good news -both for those who have a regular
chocolate habit, and those who may wish to start one."
Additional contributors to the study include Sabrina Koperski and Halbert L. White, PhD, of UC San Diego.
