Lose weight on vegan diet


People who eat a plant-based diet are less likely to be overweight or obese, reports the Physicians
Committee for Responsible Medicine. Worldwide, vegetarian populations experience lower rates of heart
disease, diabetes, high blood pressure, and other life-threatening diseases. This led researchers to
investigate the reverse: would a plant-based diet affect people who were already overweight?

A study was done with A group of 59 overweight and postmenopausal women ages 44 to 73 divided into
two groups. Half ate a low-fat vegan diet (10% fat, 15% protein, 75% carbohydrate) of vegetables, fruits,
grains and legumes. The other half followed a more moderate low-fat diet (30% fat, 15% protein, 55%
carbohydrate) based on National Cholesterol Education Program guidelines.

After 14 weeks, the vegan group lost a mean of 5.8 kg (12.7 pounds) in body weight compared with the
control group that lost a mean of 3.8 kg (8.3 pounds) body weight. The vegan group had significantly
greater reductions in body mass index and waist circumference.

"The study participants following the vegan diet enjoyed unlimited servings of fruits, vegetables, whole
grains, and other healthful foods that enabled them to lose weight without feeling hungry," said Neal
Barnard, MD, the lead author. "As they began to experience the positive effects,
weight loss and improved
insulin sensitivity, the women in the intervention group became even more motivated to follow the
plant-based eating plan
