Frying pan chemicals linked to weight gain

Researchers have found that PFAS - also known as "obesogenes" due to their interference with body weight regulation - are linked to a slower metabolic rate at times of rest.

Researchers found that people with higher blood levels of a type of chemical commonly used in non-stick cookware were more likely to put weight back on after dieting.

"Now, for the first time, our findings have pointed to a new path in which PFAS may be interfering with the regulation of body weight in humans and contributing, therefore, to the obesity epidemic", said the study's lead author, Qi Sun, Professor in the Department of Nutrition at Harvard University.

The laser causes the electrons orbiting the atom to be more energized, and these energized electrons would give off light. The atom appears as the faint blue dot at the center of the photo, but it is still not easy to see .

These chemicals - known as perfluoroalkyl substances (PFASs) - have previously been linked with cancer, hormone disruption, immune dysfunction, high cholesterol, and obesity.

The study tracked data from 621 overweight and obese participants in a clinical trial on weight loss conducted in the mid-2000s.

PFAS has been around for about 60 years and has contaminated sources of drinking water near industrial sectors, military bases, and wastewater treatment plants. "Those who gained more weight later also had the highest concentrations of PFAS in the blood, a link that was strongest among women", reveals the report, published in the journal PLOS Medicine.

Russian mercenaries in Syria reportedly killed when United States forces carried out strikes
US Defence Secretary Jim Mattis played down the incident, saying: "This could just be a local couple of guys doing something". One US official, speaking on condition of anonymity, said at least two pro-Syrian government forces were killed.

The researchers found that during the first six months (weight-loss period), participants lost an average of 6.4 kg of body weight and that they subsequently regained an average of 2.7 kg of body weight during the period of six to 24 months (weight-regain period). However, there was a significant correlation for higher baseline levels of PFAS with greater weight regain, especially in women.

They also found that higher blood concentrations of PFASs were significantly associated with lower resting metabolic rates.

"We typically think about PFASs in terms of rare health problems like cancer, but it appears they are also playing a role in obesity, a major health problem facing millions around the globe", said study co-author Philippe Grandjean, adjunct professor of environmental health at Harvard Chan School.

Wind alters Shiffrin's race lineup
Frida Hansdotter, 32, of Sweden is a consistent podium finisher, even if she only has four World Cup slalom wins to her name. Shiffrin has dominated the slalom for five years, including her Olympic gold as a teenager and the past three world titles.
