Introduction
Overweight and obesity are major public health concerns worldwide, affecting millions of people and increasing the risk of various chronic diseases.

Understanding the health risks associated with overweight and adopting sustainable weight management strategies are crucial for preventing and managing chronic diseases.
Deep Dive / Core Concepts
Defining Overweight and Obesity
Overweight and obesity are defined as abnormal or excessive fat accumulation that presents a risk to health. The body mass index (BMI) is a widely used measurement to categorize individuals as underweight, normal weight, overweight, or obese. BMI is calculated by dividing an individual's weight in kilograms by their height in meters squared (kg/m²). The WHO BMI categories are:
- Underweight: BMI < 18.5
- Normal weight: BMI = 18.5-24.9
- Overweight: BMI = 25-29.9
- Obese: BMI ≥ 30
You can use this BMI calculator to determine your BMI and understand your weight status.
Health Risks Associated with Overweight
Overweight and obesity increase the risk of various chronic diseases, including:
- Cardiovascular disease: High blood pressure, heart disease, and stroke
- Type 2 diabetes: Insulin resistance and glucose intolerance
- Certain cancers: Breast, colon, kidney, and pancreatic cancer
- Musculoskeletal disorders: Osteoarthritis and musculoskeletal pain
- Mental health disorders: Depression and anxiety
The CDC reports that overweight and obesity are associated with an increased risk of premature death, with obesity being a major risk factor for mortality.
Causes and Contributing Factors
Overweight and obesity are complex conditions influenced by multiple factors, including:
- Genetics: Genetic predisposition to weight gain
- Environmental factors: Access to unhealthy foods, sedentary lifestyle, and socioeconomic status
- Hormonal imbalance: Imbalance of hormones regulating hunger and satiety
