What is the Difference Between Obesity and Overweight?

The main difference between obesity and overweight lies in the measurement of body mass index (BMI) and the levels of body fat. Both conditions involve excess weight, but obesity is considered more severe due to the higher amount of body fat and the potential health risks associated with it.

BMI criteria: For adults, the World Health Organization (WHO) defines overweight as a BMI greater than or equal to 25, while obesity is defined as a BMI greater than or equal to 30.
Weight distribution: While both obese and overweight individuals carry excess weight, it does not necessarily imply excess fat for overweight individuals. People like athletes and bodybuilders can be overweight but not obese.
Causes: Overeating is not the only reason someone might be overweight or obese. Factors such as a sedentary lifestyle, genetics, metabolic or eating disorders, or medical conditions like thyroid problems or hormonal imbalances can also contribute to excess weight.
Health risks: Both conditions are associated with an increased risk of health issues, such as heart disease, certain types of cancer, and other adverse outcomes. However, not everyone with a high BMI is unhealthy, and weight is not the only indicator of health. Factors like healthcare access, lifestyle habits, and family history should also be considered.

In summary, obesity is a more severe condition than being overweight, as it involves a higher amount of body fat and poses greater health risks. The distinction is primarily based on BMI measurements and the levels of body fat.
