Featured health topic: Diabesity and weight loss

Diabesity is the close relationship between obesity, insulin resistance, type 2 diabetes, and metabolic syndrome. It is an important topic in preventive medicine, nutrition, and lifestyle medicine. By 2035, a large share of the global population is expected to be overweight or affected by obesity, creating major personal, medical, and economic burdens. Insulin resistance can contribute to weight gain, prediabetes, type 2 diabetes, fatty liver disease, and cardiovascular disease. Newer definitions of obesity may consider not only body mass index but also waist circumference, waist-to-hip ratio, waist-to-height ratio, and direct measures of body fat. Learn more about obesity, metabolic syndrome, ketogenic diet, GLP-1 receptor agonists, semaglutide, and tirzepatide.
