The number of people who are overweight or obese has been growing exponentially for more than 20 years. Nearly two-thirds of Americans age 20 or older are overweight (body mass index over 25), a third are considered obese (BMI over 30), and nearly 5 percent are morbidly obese (BMI 40+).

There are many roadblocks to losing weight, and one of the most common is sustaining the motivation needed to continue a weight loss program.

A newly published study (from a collaboration between researchers at Duke University, the University of British Columbia and Arizona State University) suggests that overweight people who eat with fat friends actually eat less than when they eat with slimmer friends.

A recent study by Dr. Carolyn A. McCarty of the Seattle Children’s Research Institute and her colleagues published in General Hospital Psychiatry has shown a clear link between obesity, depression, and alcoholism in women. The study investigated 393 men and 383 women at ages 24, 27, and 30, looking at their weight, alcohol usage and depression over the course of one year. In women, both alcoholism and obesity were linked with depression, while there was no connection in men.
