The "Obesity Epidemic" refers to the rapid increase in obesity rates worldwide, particularly in developed countries. Obesity is defined as having an excessive amount of body fat, which can lead to various health issues, including heart disease, diabetes, and certain cancers. Factors contributing to this epidemic include poor diet, lack of physical activity, and environmental influences. This public health crisis affects people of all ages, with children being particularly vulnerable. The rise in obesity is linked to the availability of high-calorie, low-nutrient foods and sedentary lifestyles. Addressing the obesity epidemic requires a multi-faceted approach, including education, community programs, and policy changes to promote healthier living.
