Health Risks of Excess Body Fat

According to the CDC (2023), obesity affects 42.4%, making it one of the most common preventable causes of death. In the U.S, it is linked to approximately 111,909–365,000 deaths per year as estimated by the WHO. Obesity decreases one’s quality of life, negatively impacts mental well-being, and elevates the risks of numerous conditions such as cardiovascular disease, stroke, diabetes, some types of cancer, and obstructive sleep apnea.
