Association MEDITERRANEAN DIET (INCLUDING
NUTS) MORE EFFECTIVE THAN LOW-FAT DIETS FOR WEIGHT LOSS
ATLANTA (October 5, 2001) -
Pecans may help consumers lose weight, according to new research
from Brigham and Women's Hospital (BWH) and the Harvard School
of Public Health. The research, published in the October
5 issue of the International Journal of Obesity, found that
people following a moderate-fat weight loss diet that contained
unsaturated fats (including pecans and other varieties of
nuts) were able to keep weight off for a longer period of
time than people following a traditionally recommended low-fat
diet. "In our study, three times
as many people trying to lose weight were able to stick to
a Mediterranean-style diet versus the low-fat diet," said
study lead-author Kathy McManus, MS, RD, director of nutrition
at BWH. "Motivation and adherence are very hard to sustain
in any weight loss programs, but the results from this study
suggest that the tastier the food, the greater overall success
of the diet plan - even if it does include moderate amounts
of fat." According to the researchers,
a moderate-fat diet based on the diets of southern Europe
and the Mediterranean allows for a greater variety of foods
that are considered very appetizing compared with a strict,
bland, low-fat diet. The main dietary fats in a typical Mediterranean
diet are unsaturated such as the type of fat found in pecans,
other nuts and olive and canola oils. In the study of 101 overweight
men and women, half were instructed to eat a low-fat diet
(20% calories from fat) and half to eat a moderate-fat diet
(35% calories from fat, mostly monounsaturated from nuts,
peanut butter, olive and canola oils). All participants were
given guidelines to eat a diet of approximately 1,200-1,500
calories that was low in saturated fat and cholesterol. Only
one in five study participants could stick to the low-fat
diet while more than half stuck to the moderate fat diet.
Both groups lost an average of 11 pounds in the first year.
The moderate fat group kept a significant amount of weight
off for 18 months, whereas the low-fat group did not. |
