Overweight vs. Obese: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on January 11, 2024
Overweight is having more body weight than is optimally healthy; obesity is a higher degree of excess weight with more severe health risks.
Key Differences
Overweight refers to having more body weight than is considered normal or healthy for a certain height, often measured by Body Mass Index (BMI) over 25 but less than 30. Obesity is a more severe form of excess weight, defined as a BMI of 30 or higher.
Being overweight can increase the risk of various health conditions like hypertension, type 2 diabetes, and heart disease. Obesity significantly heightens these risks and can lead to more severe health issues like stroke, certain cancers, and type 2 diabetes.
Overweight can result from a variety of factors including overeating, lack of physical activity, genetics, and certain medical conditions. Obesity often results from similar causes but is typically associated with more severe imbalances in diet and activity levels.
Overweight individuals may manage their weight through diet and exercise, often aiming to prevent progression to obesity. Obesity management may require more intensive interventions like medical treatment, structured diet plans, or even surgery.
Overweight is a common public health concern, indicating potential lifestyle imbalances. Obesity is considered a more serious public health crisis due to its higher association with chronic diseases and significant healthcare costs.
