Obesity

Overweight and obesity are defined by the WHO as abnormal or excessive fat accumulation that presents a risk to an individuals health.

Overweight and obesity are major risk factors for a number of chronic diseases, including diabetes, cardiovascular diseases and cancer and while it was once an issue only in high income countries, overweight and obesity has now dramatically risen in low- and middle-income countries.Such countries are now facing a "double burden" of disease, for while they continue to deal with the problems of infectious disease and under-nutrition, they are also experiencing a rapid upsurge in chronic disease risk factors such as obesity and overweight, particularly in urban settings.

What is Obesity?

Obesity and overweight have in the last decade become a global problem - according to the World Health Organization (WHO) back in 2005 approximately 1.6 billion adults over the of age 15+ were overweight, at least 400 million adults were obese and at least 20 million children under the age of 5 years were overweight.

Drug combination shows greater weight loss while preserving muscle mass

A recent research study found that a combination of the GLP-1 receptor agonist semaglutide and bimagrumab, an antibody that blocks activin signaling pathways, results in greater weight loss while also preserving lean mass, such as skeletal muscle and connective tissue.

Mapping the year-one weight trajectory after stopping GLP-1s

A year after stopping taking weight loss drugs such as Ozempic and Wegovy, people regain, on average, 60% of their lost weight – but beyond this, their weight regain plateaus, with individuals managing to keep off 25% of the weight lost to treatment, say researchers at the University of Cambridge.

How are GLP-1 drugs reshaping treatment for obesity, diabetes, and heart disease?

A comprehensive Lancet review synthesizes evidence from major clinical trials showing that GLP-1 receptor agonists and next-generation incretin therapies deliver substantial weight loss while reducing cardiovascular and kidney risks. Emerging dual, triple, and oral agents may further expand treatment options and improve outcomes across obesity, type 2 diabetes, and related metabolic diseases.

The surprising neurological benefits of GLP-1s

For people with chronic migraine, taking glucagon-like peptide-1 receptor agonists, or GLP-1 drugs, for other conditions such as diabetes and weight loss, was associated with fewer emergency department visits and hospitalizations overall, and with less need for medications used to stop and prevent migraine attacks, according to a preliminary study released March 1, 2026, that will be presented at the American Academy of Neurology's 78th Annual Meeting taking place April 18-22, 2026, in Chicago and online.
