Does Vitamin D Deficiency Cause Obesity or Vice Versa?
Caroline Apovian, MD December 27, 2022 Caroline Apovian, MD A recent study found that people with obesity have lower blood levels of vitamin D than people of healthy weight. This association of obesity with low vitamin D levels has led to much speculation on whether low vitamin D levels cause obesity or whether obesity causes low vitamin D levels. The interest in this...

Naturally occurring peptide may tackle the ‘root cause’ of obesity-related conditions
by University of Birmingham Credit: CC0 Public Domain Research published today in Clinical and Experimental Immunology shows that a peptide (small protein) called PEPITEM could provide a revolutionary approach to reducing the risk of type 2 diabetes and other obesity-related diseases such as hepatic steatosis (fatty liver). The researchers used an animal model of obesity to investigate whether...

Mouse model shows obesity in early life promotes later inflammatory disease, even after weight loss
by Bob Yirka, Medical Xpress Credit: CC0 Public Domain A team of researchers affiliated with multiple institutions in Canada has found that obesity in young mice can lead to inflammatory disease later in life even if the mouse is no longer overweight. In their paper published in the journal Science, the group describes studying early life obesity in...

Research helps explain why obesity is more dangerous for men
by York University Graphical abstract. Credit: iScience (2022). DOI: 10.1016/j.isci.2022.105811 A newly published study from York University sheds light on the biological underpinnings in sex differences in obesity-related disease, with researchers observing “striking” differences in the cells that build blood vessels in the fatty tissue of male versus female mice. Men are more likely than women to...
