What is Overweight?
According to the World Health Organization (WHO), a person is classified as overweight if their BMI falls between 25 and 29.9. This means that their body weight is higher than what is considered normal for their height, but not yet at a level that is classified as obesity.
Causes
- Diet: Consuming high-calorie foods, especially those rich in sugar, fats, and processed ingredients, can lead to weight gain. Overeating or frequent snacking, particularly on unhealthy foods, adds extra calories.
- Physical Inactivity: Sedentary lifestyles are a major contributor. With the rise of desk jobs, screen time, and modern conveniences, people burn fewer calories daily, leading to weight gain.
- Genetics: Genetic predisposition can affect how a person’s body stores fat and processes food. Some people are more likely to gain weight due to inherited traits.
- Environment: Accessibility to unhealthy foods, lack of safe spaces for physical activity, and cultural norms around eating and body image influence weight gain.
- Psychological Factors: Emotional eating, stress, and conditions like depression can drive individuals to consume excess food, often unhealthy, leading to weight gain.
- Medical Conditions: Certain medical conditions (e.g., hypothyroidism, PCOS) and medications can cause weight gain by affecting metabolism or increasing appetite.
Health Implications
Overweight Individuals who are classified as overweight have an increased risk of developing health issues compared to those with a normal weight. Common conditions associated with being overweight include:
- High blood pressure
- Elevated cholesterol levels
- Insulin resistance, which can lead to type 2 diabetes
- Sleep apnea
- Joint and muscle pain due to the additional stress on bones and muscles
Prevention and Treatment
Preventing and treating overweight and obesity requires a multifaceted approach. There is no one-size-fits-all solution, and the strategies that work best will depend on an individual's specific circumstances, including their overall health, lifestyle, and psychological factors.
- Diet and Nutrition: A healthy, balanced diet is key to managing weight. This typically involves reducing calorie intake, especially from processed and sugary foods, and increasing the consumption of fruits, vegetables, whole grains, lean proteins, and healthy fats.
- Physical Activity: Regular exercise is crucial for both preventing and treating overweight and obesity. The Centers for Disease Control and Prevention (CDC) recommends at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity aerobic activity per week, along with muscle-strengthening activities on two or more days per week.
- Behavioral Changes: Addressing psychological factors such as stress, emotional eating, and sedentary behaviors is essential for long-term weight management. Behavioral therapy, support groups, and counseling can be helpful in making lasting lifestyle changes.
- Medical Interventions: In some cases, lifestyle changes alone may not be enough to achieve significant weight loss. Medical interventions, such as prescription weight-loss medications or bariatric surgery, may be considered for individuals with severe obesity, especially when other weight-loss efforts have been unsuccessful.

- Class 1 (Moderate Obesity): BMI of 30-34.9
- Class 2 (Severe Obesity): BMI of 35-39.9
- Class 3 (Morbid Obesity): BMI of 40 or higher
Health Implications
The health risks associated with obesity are much more severe and can lead to life-threatening conditions. Obesity is a major risk factor for:
- Cardiovascular diseases, including heart disease and stroke
- Type 2 diabetes
- Certain types of cancer, such as breast, colon, and kidney cancer
- Liver disease, including fatty liver disease
- Osteoarthritis due to increased wear and tear on joints
- Reproductive issues, including infertility in both men and women
- Mental health conditions, including depression and anxiety

Portion control and mindful eating are also important strategies.
- Physical Activity: Regular exercise is crucial for both preventing and treating overweight and obesity. The Centers for Disease Control and Prevention (CDC) recommends at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity aerobic activity per week, along with muscle-strengthening activities on two or more days per week.

Medical interventions, such as prescription weight-loss medications or bariatric surgery, may be considered for individuals with severe obesity, especially when other weight-loss efforts have been unsuccessful.
- Ongoing Support: Weight management is a lifelong journey, and ongoing support from healthcare providers, dietitians, and fitness experts can help individuals stay on track. Regular check-ins, adjustments to the weight-loss plan, and encouragement can make a big difference in maintaining a healthy weight.
