Skipping one night of sleep causes healthy adults to see a spike in immune cells linked to chronic inflammation, a key feature of obesity, according to new research. It highlights the powerful link between sleep and immune health.

Researchers at Columbia University Irving Medical Center have identified the specific neurons in mice brains that tell them they've eaten enough. This fascinating discovery could play a big role in the future of weight loss treatments for humans.

A new study has confirmed that weight loss or bariatric surgery is safe and very effective, and, for a large percentage of people who were diabetic before the surgery, meant that they didn’t require diabetes medication five years after.

There's a growing body of evidence that gold nanoparticles can trigger significant weight loss that targets fat, without affecting muscles, plus heal organs and improve blood-glucose levels. A new study makes a strong case for the first-ever human trial.

Scientists remain puzzled as to why some people taking popular weight loss and diabetes medications like Ozempic and Wegovy are losing their vision suddenly, highlighting that there's still so much we don't know about this life-changing class of drugs.

A brand new candidate for weight-loss treatment is on the table, with scientists uncovering for the first time how a hormone produced by the hypothalamus during sleep has a direct impact on appetite regulation and metabolism.

If you're one of the 13% of US adults who has taken a GLP-1 drug for weight loss, you may know that while fat seemingly melts away, so too does muscle. And, so far, there's not a lot you can do about it. But one new discovery may change this.

Is obesity a disease or a risk factor for disease? It's a contentious question. In a new report, the Global Commission on Clinical Obesity strives to settle the enduring debate, introducing a new framework that seeks to redefine obesity.

Nearly half of US adults admit they’d take one of the newer, injectable weight loss drugs; that number falls significantly when they learn the weight might come back when the meds are stopped. It’s something that has medical professionals concerned.

It's controversial, but slogging passengers with a body-weight surcharge is still on the table for many airlines, be it for profit or the environment. But it seems attitudes, particularly among younger travelers, is shifting on the contentious issue.

Balloons that trick the stomach into feeling full have long been used for weight loss. But, they become less effective the longer they stay inflated. Engineers have devised a balloon that inflates and deflates on demand – it reduced food intake by 60%.
