(Love to see the full study!)

" The weight loss came despite the fact that the women were given no

limits on their portion sizes or daily calories and despite the fact

that the vegan diet boosted their carbohydrate intake. "

Low-fat vegan diet may spur weight loss

A diet free of animal products and low in fat may help trim the

waistline without the task of strict calorie watching, a new study

suggests.

Researchers found that of 64 postmenopausal, overweight women, those

assigned to follow a low-fat vegan diet for 14 weeks lost an average

of 13 pounds, compared with a weight loss of about 8 pounds among

women who followed a standard low-cholesterol diet.

The weight loss came despite the fact that the women were given no

limits on their portion sizes or daily calories and despite the fact

that the vegan diet boosted their carbohydrate intake.

" People imagine carbohydrates to be fattening, but they are not, " said

lead study author Dr. Neal D. Barnard, an adjunct associate professor

of medicine at Washington University in Washington, D.C.

He is also president of Physicians Committee for Responsible Medicine,

a nonprofit group that advocates vegetarianism as part of preventive

medicine.

The greater weight loss among women on the vegan diet may stem from

specific metabolic effects, Barnard told Reuters Health.

He pointed out that the diet improved the women's sensitivity to

insulin, a hormone that ushers sugar from the blood and into cells to

be used for energy. This was also accompanied by an increase in what's

known as the thermic effect of food -- the amount of calories the body

expends to process and store food.

The vegan diet improved women's insulin sensitivity to a greater a

degree than the comparison diet did -- though the difference was not

statistically significant, meaning the finding could be due to chance.

Barnard and his colleagues at Washington and town

universities report the findings in the American Journal of Medicine.

Vegan diets eschew all animal products, including dairy and eggs, in

favor of fruits and vegetables, grains, nuts and beans. Although

high-protein weight-loss regimens have painted carbohydrates as the

enemy, a number of studies have found that vegetarians and vegans, who

tend to eat a lot of fiber- and vitamin-rich carbohydrates, are much

less likely to be overweight than meat-eaters.

Women in the current study found the vegan diet easy to follow,

according to Barnard, because they were not asked to count calories or

keep tabs on portion sizes. They were, however, told to avoid added

oils, nuts and seeds to keep their fat intake down.

Women in the comparison group followed a diet based on National

Cholesterol Education Program guidelines, which meant restricting fat

to less than 30 percent of calories and protein to about 15 percent of

calories.

Participants, who ranged in age from 44 to 73, also attended weekly

meetings that included nutrition and cooking lessons.

Based on dietary records the women kept, both groups ended up reducing

their calorie intake by almost 400 calories per day, on average. But

those on the vegan diet lost more weight.

Despite the restrictions of going vegan, Barnard maintained that it's

easy to take on the lifestyle. " Just eat fruits, vegetables, beans and

whole grains, " he said. " Everything you're eating is good for you. "

It is wise, he noted, to take a multivitamin, particularly to get

enough vitamin B12, which is found naturally only in animal products.
