Overweight refers to a condition where a person's body weight is higher than what is considered healthy for their height. This is often measured using the Body Mass Index (BMI), which calculates weight in relation to height. A BMI of 25 to 29.9 is typically classified as overweight, while a BMI of 30 or higher is classified as obese. Being overweight can increase the risk of various health issues, including heart disease, diabetes, and certain types of cancer. Maintaining a balanced diet and engaging in regular physical activity are important strategies for managing weight and promoting overall health.
