The increase was highest in ...

Obesity Might Be 'Contagious' Among Teens

Teens who live around lots of obese or overweight kids come to see their body types as ideal, a new study suggests.

As a result, these teens tend to be obese or overweight themselves, researchers say.

"Higher obesity rates may normalize unhealthy weight in teens and make obesity prevention harder," said lead researcher Ashlesha Datar. She's a senior economist at the Center...

Belly Fat Can Lead to a Sudden Attack of Pancreatitis: Study

Obesity is not only tied to chronic diseases like type 2 diabetes, researchers now say it's also linked to a painful condition known as acute pancreatitis.

"We were able to demonstrate that fat within the belly is rapidly degraded during acute [sudden-onset] pancreatitis, but not during diverticulitis [another condition that causes abdominal pain]," said researcher Vijay Singh. He's a...

Weight-Loss Surgery May Lower Colon Cancer Risk

Obesity increases the risk for colon cancer, but weight-loss surgery may bring the risk back to normal, French researchers report.

Bad Sleep, Bad Diet = Bad Heart?

It's a dangerous equation: Poor sleep triggers a bad diet, and the two can equal a higher risk for obesity and heart disease in women, a new study contends.

"Women are particularly prone to sleep disturbances across the life span, because they often shoulder the responsibilities of caring for children and family and, later, because of menopausal hormones," said study senior author Bro...

Patients Who Quit Smoking Before Weight-Loss Surgery Often Relapse: Study

Many people who quit smoking before having weight-loss surgery go back to cigarettes after the procedure, a new study finds.

The study tracked data on more tha...

Calories Per Serving or the Whole Package? Many Food Labels Now Tell Both

For decades, consumers have often been puzzled by what a "serving" means on Nutrition Facts labels on foods.

Well, things might have just gotten a bit clearer. New labeling regulations went into effect in January, and on many products you'll now see the total amount of calories (and various nutrients) per serving, as well as for the whole package.

"With the introduction of t...

Victoria's Secret Models Are Skinnier Now, as Average Woman's Waistline Widens

For the average American woman, it's now tougher than ever before to match the "ideal" beauty set by supermodels, new research shows.
