In this article, we will delve into the complexities of Class 3 obesity, exploring its definition, causes, and consequences, as well as evidence-based approaches to mitigate its impact on overall health.

Introduction

Obesity is a multifaceted and chronic condition characterized by excessive body fat accumulation, posing significant health risks. The World Health Organization (WHO) defines obesity as a global epidemic, with far-reaching consequences for individuals, communities, and healthcare systems. In the United States, the Centers for Disease Control and Prevention (CDC) reports that more than two-thirds of adults are overweight or obese. Class 3 obesity, also known as severe, extreme, or morbid obesity, is a critical subcategory of obesity that warrants attention due to its profound impact on health.
