What ratio of society is able to maintain healthy weight?

The ratio of individuals maintaining a healthy weight varies by region and demographic factors, but studies suggest that about one-third of adults in many developed countries achieve a healthy weight according to body mass index (BMI) standards. In the U.S., for example, the CDC reports that approximately 32% of adults are classified as having a healthy weight. However, this figure can fluctuate based on lifestyle, socioeconomic status, and access to healthy food options. Overall, a significant portion of the population struggles with weight management due to various environmental and behavioral influences.
