The more fit you are when you start a weight-loss program, the more weight you could lose, a new study says.
"This research could help us improve the design of our weight-loss programs and suggests that adults with very poor fitness may benefit from additional exercise support during a weight-loss program to achieve higher levels of moderate-to-vigorous physical activity and improve l...
There's been a sharp increase in high blood pressure-related deaths in the United States, particularly in rural areas, a new study says.
Researchers analyzed data on more than 10 million U.S. deaths between 2007 and 2017 and found that death rates linked to high blood pressure (hypertension) rose 72% in rural areas and 20% in urban areas.
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...
Obesity increases the risk for colon cancer, but weight-loss surgery may bring the risk back to normal, French researchers report.
People who are obese have a 34% higher risk of colon cancer than the general population, but any type of bariatric (weight-loss) surgery can bring their risk back in line, according to the authors of a new study.
Bacteria may play a role in the development of type 2 diabetes in severely obese people, researchers report.
They analyzed bacterial genetic material in blood and tissue samples taken from 40 severely obese people during weight-loss surgery. Half of the patients had type 2 diabetes, while the other half showed insulin resistance but didn't have diabetes.
Weight-loss surgery is as effective for people who became obese before age 20 as for older patients, new research shows.
For the study, researchers from the University of Gothenburg, in Sweden, analyzed data from just over 4,000 obese adults. Half had undergone weight-loss surgery, half did not. They were divided into three groups based on their body mass index (BMI) at age 20: normal...
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...
Many people who quit smoking before having weight-loss surgery go back to cigarettes after the procedure, a new study finds.
Researchers followed 1,770 adults for seven years after they had weight-loss surgery at 10 U.S. hospitals. While about 14% smoked in the year before surgery, that fell to 2% in the month before their operation.
A clinical trial of the weight-loss drug Belviq (lorcaserin) shows an association with an increased risk of cancer, and the U.S. Food and Drug Administration is requesting that its maker withdraw the drug from the U.S. market.
Eisai Inc. has already "submitted a request to voluntarily withdraw the drug," Dr. Janet Woodcock, who directs the FDA's Center for Drug Evaluation and Research...
When pregnant women use cosmetics containing parabens, their children may have a greater likelihood of becoming overweight, a new study suggests.
Parabens are chemicals that have long been used as a preservative in cosmetics and body care products. A number of studies have suggested that parabens mimic estrogens in the body and may disrupt the normal function of hormones.
The Harvard-associated lab that created the "CoolSculpting" process of reducing fat says it's on the trail of the next advance in nonsurgical slimming.
CoolSculpting freezes fat cells by applying an ice-cold gel pad to the skin, causing cells to die off and either be flushed away or absorbed by the body, said lead researcher Dr. Lilit Garibyan, an investigator at the Wellman Center for ...
People considering obesity surgery have a lot to think about, including the specific procedure they want. Now a large study finds that one surgery is tied to a higher rates of hospitalization in the years afterward.
Looking at medical records from more than 33,000 U.S. patients, researchers found that those who underwent gastric bypass surgery had higher rates of hospitalization in th...
People with what's known as the "metabolic syndrome" are vulnerable to recurring blood clots, new research shows.
Metabolic syndrome is a collection of conditions, including obesity, high blood sugar, high cholesterol and high blood pressure. These factors put people at risk for diabetes, heart disease and a type of blood clot known as deep vein thrombosis (DVT), researchers say.
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.
You know that you need to watch your weight to lower your risk for heart disease, but that is far from the whole story.
It is possible to be overfat without being overweight, meaning that you're storing fat within your body even though the scale says you're at a normal weight. And that distinction is key when it comes to heart health.
If your child is obese, new research suggests that those extra pounds can alter the results of routine blood tests.
"We performed the first comprehensive analysis of the effect of obesity on routine blood tests in a large community population of children and found that almost 70% of the blood tests studied were affected," said study first author Victoria Higgins, from the Hospital...
Rising obesity rates worldwide may be contributing to the climate crisis, researchers report.
"Our analysis suggests that, in addition to beneficial effects on morbidity, mortality and health care costs, managing obesity can favorably affect the environment as well," said study corresponding author Faidon Magkos, from the department of nutrition, exercise and sports at the University ...
Obesity in middle age is associated with an increased risk of dementia later in life, according to a study of more than 1 million women in the United Kingdom.
Those who were obese in their mid-50s had 21% greater risk of being diagnosed with dementia 15 or more years later, compared with women who had a healthy weight, a team of British and international researchers found.
Childhood obesity may be linked to changes in brain structure that might result in impulsive kids who struggle with problem-solving, a new study reports.
Overweight and obese children tend to have a thinner prefrontal cortex, a part of the brain associated with decision-making and problem-solving. These same kids performed more poorly on games designed to evaluate those skills, said l...
Obese teenagers can have certain brain differences from their thinner peers -- changes that might signal damage from inflammation, a new, preliminary study suggests.
Using advanced MRI techniques, researchers found that obese teenagers tended to have signs of decreased "integrity" in the brain's white matter. White matter contains the fibers that connect different areas of the brain.<...
Four of five older children and teens around the world don't get the recommended amount of physical activity, a new study says.
Researchers analyzed data gathered between 2001 and 2016 from 1.6 million students, aged 11 to 17, in 146 countries. They found that 81% of them did not meet World Health Organization recommendations for an hour of moderate-to-vigorous physical activity e...
After the University of California, San Francisco, banned sales of sugary drinks, employees started downing less liquid sugar -- and their waistlines showed it.
In a before-and-after study, researchers found that the ban, begun in 2015, cut employees' intake of sugary drinks by almost 50%. And within 10 months, their collective waist size had shrunk by almost an inch.
Having a fast-food joint right down the block might not bode well for your child's chances of staying a healthy weight, new research suggests.
Among the more than 1 million children who attend New York City public schools, the closer kids lived to places that sell unhealthy food, the greater their risk was for packing on the pounds, the study found.
There are many unanswered questions about the long-term safety and impacts of artificial sweeteners in children, a new American Academy of Pediatrics (AAP) policy statement says.
The AAP statement also recommends that the amount of artificial sweeteners should be listed on product labels to help parents and researchers better understand how much children are consuming, and the possib...
Weight-loss surgery should be more widely used to treat severely obese children and teens, a leading pediatricians' group says.
Severe obesity is a serious and worsening public health crisis among U.S. youngsters, and weight-loss surgery is one of the few effective ways of treating it, according to the American Academy of Pediatrics (AAP) in its new policy ...
Adults who pack on pounds between their mid-20s and middle age have an increased risk of premature death -- and the same is true of those who lose weight from middle to late adulthood, according to a new study.
The findings suggest that maintaining normal weight throughout adulthood reduces the risk of early death, the China-based researchers said.
