[Expanding definition of obesity risks reinforcing stigma]

Area of Science:

• Medical Science
• Public Health
• Sociology

Background:

• The definition of obesity and its health risks lacks scientific consensus.
• Body Mass Index (BMI) is widely used to define obesity despite limited evidence of its accuracy.
• Anti-obesity medications are often approved based on weight reduction, not proven health benefits.

Purpose of the Study:

• To critically examine the current definitions and treatments of obesity.
• To highlight the limitations of BMI and weight-centric approaches in healthcare.
• To advocate for a more nuanced approach to obesity, considering health risks and social factors.

Main Methods:

• Literature review of scientific consensus on obesity.
• Analysis of criteria for anti-obesity drug approval.
• Examination of the social and ethical implications of obesity definitions.

Main Results:

• There is no clear consensus on the health risks associated with specific amounts of body fat.
• BMI's accuracy in defining obesity at an individual level is questionable.
• The focus on weight reduction in obesity treatments may not translate to improved health outcomes.

Conclusions:

• The expanding definition of obesity risks stigmatizing individuals and reinforcing harmful moral judgments.
• Healthcare must integrate medical necessity with social norms, directing resources effectively.
• Acknowledge that larger body sizes do not automatically equate to poor health or require intervention.
