The words “overweight” and “obese” are often used interchangeably in casual conversation. Still, they are two different conditions with different health implications. This knowledge is critical to solving health problems related to overweight. So, what are these overweight vs obese differences?
Overweight vs Obese: Definitions
A BMI of 25 to 29.9 is considered overweight. This indicates the person is overweight — heavier than ideal for their height, but not as heavy as they come. Being overweight means having more body fat than is optimally healthy, but though still serious, it is usually less severe than obesity.
Obesity can be defined as a body mass index (BMI) of 30 or greater. It refers to a more severe state characterized by excessive body fat and is associated with several health risks. Obesity is usually divided into groups by BMI:
- Class 1 Obesity: BMI of 30 to 34.9
- Class 2 Obesity: BMI of 35 to 39.9
- Class 3 Obesity (Morbid Obesity): BMI of 40 or higher.
Body Mass Index (BMI) Measurement
BMI has been the most widely used method for classifying individuals as overweight or obese. It is computed using the formula:
BMI= Weight in kg /Height in m2
BMI is a useful estimate of body fat based on weight and height, but this metric has limitations. It does not take into account differences between muscle and fat mass (a very muscular person may have a high BMI, but not much excess body fat).
Alternative Measures Beyond BMI
While BMI remains a standard measurement for assessing weight categories, experts have suggested alternative methods that may provide a more accurate representation of an individual’s health status:
- Body Fat Percentage (BFP): This measure assesses the body’s fat proportion compared to lean mass. A BFP of 30% or more for women and 25% or more for men typically indicates obesity.
- Waist Circumference: This measurement helps assess abdominal fat distribution. A waist circumference greater than 35 inches for women or 40 inches for men indicates an increased risk for metabolic diseases.
- Health Indicators: Other factors such as blood pressure, cholesterol levels, insulin sensitivity, and lifestyle habits should also be considered when evaluating an individual’s health status.
Overweight vs Obese: Health Implications
Both overweight and obesity are correlated with increased risks of many diseases, including:
- Cardiovascular Diseases: They both increase the risk of heart disease and stroke through hypertension or high cholesterol levels and many others.
- Type 2 Diabetes: Carrying excess weight may cause insulin resistance and can vastly increase the risk of developing diabetes.
- Joint Problems: Excess weight puts more stress on joints, which can cause osteoarthritis.
- Some cancers: Several cancers, including breast, colon, and endometrial cancers, are more prevalent in people who are obese.
- All of these risks worsen with increasing body fat, which is why being classified as obese represents a greater health risk than being simply overweight.
Causes and Risk Factors
There are several reasons behind being overweight vs obese. Usually, they include a mix of genetic, environmental, and behavioral factors:
- High-Calorie Diet: A diet high in sugars and fats is the main cause of weight gain.
- Physical Activity: A sedentary lifestyle limits calorie burn, resulting in weight gain.
- Genetics: Genetic factors can affect your metabolism and how fat is distributed in your body.
- Chronic Stress and Psychological Factors: A high-stressed person is likely to overeat due to a mind or emotional state.
Societal Perceptions and Stigma
Society often stigmatizes individuals who are overweight or obese, associating these conditions with laziness or lack of self-control. This stigma can have profound psychological effects, leading to issues such as low self-esteem, anxiety, and depression. The negative societal perceptions surrounding weight can also deter individuals from seeking medical help or engaging in healthy lifestyle changes.
Consult a doctor or other healthcare professional
For someone who is considered overweight or obese, going to a doctor’s office can be difficult. But people, whatever their weight, deserve medical care that is respectful and considerate.
If you need to maintain a healthy weight, it may be a good idea to consult with a professional, in particular a registered dietitian who can provide guidance on healthy eating that is right for your body. They can even share a few recipes for drinks that help with weight loss.
You can also work with bariatric doctors (or bariatricians), as they specialize in weight loss. Keep in mind that simply dropping pounds won’t reduce heart disease risk.
If your doctor thinks you need to drop a few pounds, have them tell you what to eat or what exercises to do, or at least refer you to someone who can. If you think your doctor is focusing more on weight loss than on the care you require, do not hesitate to complain. An example would be: “I am not comfortable talking about my weight. How about you talk about my health condition instead?”
Overweight vs Obese: Final Thoughts
To plan better prevention and treatment strategies, it is essential to understand the differences between overweight vs obese to reduce the prevalence of both and their associated health consequences. Both mean excess body weight that may harm health but differ vastly in degree and consequences.
Understanding that being overweight and obese are not necessarily synonymous with unhealthiness while still recognizing the increased risks associated with obesity can help people be aware of this distinction and to seek medical help when it is appropriate. Additionally, overhauling the societal stigma of these conditions is vital for creating an environment where people can seek a healthier life without worrying about what others think.
A more holistic approach to healthcare that considers the broader context in which individuals live—including their lifestyle choices, access to healthcare, mental health, and genetic predispositions—will allow healthcare providers to develop more individualized interventions that address the person’s particular needs.
