Can a fat body be a healthy body? Using a new grading tool that takes health issues into account in addition to body mass index, it may be possible for healthy obese people to have the same lifespan as normal-weight people. The findings were released Monday in a study in the journal Applied Physiology, Nutrition, and Metabolism . Researchers looked at data on 6,224 obese men and women who were followed on average for about 16 years. The participants were part of the Aerobics Center Longitudinal Study who attended the Cooper Aerobics Center in Dallas.

Having bariatric surgery doesn't mean you have to take it easy on exercise. A study finds that after surgery, exercising regularly at a moderate to vigorous pace may be perfectly fine -- and might improve one's quality of life. The study, published online recently in the journal Obesity , assigned 33 people with an average BMI of 41 (considered class III obesity, or morbidly obese) to either a 12-week exercise program or to a control group. The exercise group started out expending 500 calories a week, gradually increasing that to reach a goal of burning 2,000 calories a week.

Weight-loss surgery has been reserved for people who are morbidly obese, with a body mass index of 40 or greater. However, both gastric bypass surgery and adjustable gastric banding surgery is increasingly performed on less-obese people. That may be a good thing, according to a new study. Researchers at Stanford University looked at the outcomes of 981 people who had gastric bypass surgery. The patient's BMIs ranged from below 35 to greater than 50. The lower-BMI patients had better outcomes than the higher-BMI patients.

Overweight and obese young adults may be known by the company they keep--other overweight and obese people. But if those friends and family members are trying to lose weight, they could be a good influence. How social groups influence our health was the subject of a 2007 New England Journal of Medicine study that found that people who had close friends who were fat might triple their risk of becoming obese as well. A similar connection was found in a study from the June issue of the journal Obesity . But researchers found that connection may also help people lose weight.

Rejoice, obese people trying to slim down. You may be able to occasionally indulge in steaks and bacon and eggs cooked in butter and still not damage your arteries, according to a study's findings. Researchers at Johns Hopkins University randomly assigned 46 obese men and women age 30 to 65 and to one of two diet and exercise programs for six months. Participants in the low-carb group ate a diet consisting of no more than 30% of calories from carbs (pasta, bread and fruit), and 40% from fats (dairy, nuts and meats)

Nobody's perfect. We all have bad habits we just can't seem to shake. Cigarettes have a hold on some people; others can't say no to alcohol, sweets or a life on the couch in front of the television. As much as we may want to make more healthful choices, change is difficult. Even the awareness that our behaviors can harm us often isn't enough to make us mend our ways. Amazingly, people who have already suffered heart trouble, diabetes or other lifestyle-related illnesses —people who intimately know the consequences of their behaviors — often have an especially hard time turning things around.

The one-two punch of high-intensity exercise and healthful eating was helpful in getting overweight and obese people to slim down, a study finds. The study, presented this week at the National Obesity Summit in Montreal, Canada, focused on data on 62 overweight and obese men and women involved in a nine-month program at the Montreal Heart Institute . The participants engaged in two to three weekly one-hour supervised exercise sessions and...

Losing weight might not only help your waistline, but just maybe your memory too. A new, small study would seem to suggest that obese patients who have their fat surgically removed show improvements in memory and concentration when compared to obese people who didn't have surgery. Researchers from Kent State University in Ohio gave a cognitive and memory test to 150 obese patients in New York and North Dakota. The tasks involved navigating through computer mazes and recalling word lists and as many animal names as possible in 60 seconds.

I'd never seen anyone this big move this fast. Shay Sorrells, all 350 pounds of her, was up ahead on the bike path, absolutely flying. Furiously pumping arms and legs, the former "Biggest Loser" contestant was riding a Street Strider, a newfangled rolling elliptical machine. Once 476 pounds, she'd taken the Strider home after leaving the show and was riding it an hour a day around Newport Bay, hammering the flats at 13 miles per hour and soaring down hills at 30 — no different than me, about half her size.
