Obesity is defined by the CDC as having a body mass index (BMI) of 30 or higher. BMI is calculated based on your weight and height. An adult with a BMI of 30 or higher is considered obese.
Obesity rates have been rising steadily over the past few decades. According to recent CDC data, over 40% of American adults are obese. This high obesity prevalence comes with risks:
- Heart disease and stroke: Obesity stresses the cardiovascular system and increases risk factors like high blood pressure.
- Type 2 diabetes: Excess weight contributes greatly to insulin resistance.
- Certain cancers: Obesity raises risks for cancers of the colon, pancreas, kidney and more.
- Many other health conditions also become more likely with obesity.
What causes someone to develop
obesity? The key driver is an imbalance between the calories you take in from food and drink vs. the calories you burn.
Genetics and the
obesogenic environment we live in also play big roles by making weight gain more likely for some people.
Lifestyle changes are key to supporting weight loss:
- Choosing nutrient-dense, low processed foods
- Managing calories and portions
- Increasing physical activity levels
In some cases, anti-obesity medications or even bariatric surgery may be considered to jumpstart weight loss.
