Recent studies have revealed a dramatic increase in obesity rates among adults in both the United States and the United Kingdom. Nearly 70% of US adults now meet a new, more stringent definition of obesity, according to multiple reports highlighting the alarming trend. Researchers describe the situation in America as a crisis that is even worse than previously thought. In the UK, up to eight million individuals may also face reclassification as obese under new weight guidelines. These findings underscore the urgent health challenges posed by rising obesity rates in these countries.
