Weight loss is the process of reducing total body weight. This typically occurs when the body burns more calories than it consumes, leading to a decrease in fat, muscle, or water weight. It can be intentional, such as when someone follows a diet or exercise plan, or unintentional, due to illness or other factors.
Weight loss is important for health because maintaining a healthy weight can reduce the risk of various diseases, including heart disease, diabetes, and certain cancers. It can also improve overall well-being, increase energy levels, and enhance physical mobility. For individuals who are overweight or obese, losing weight can be a crucial step towards achieving better health.
In the body, weight loss happens when there is a calorie deficit. This means the body uses more energy than it takes in from food and drink. The body then turns to stored fat for energy, leading to weight reduction. This process involves complex interactions between hormones, metabolism, and physical activity.
If someone experiences unexpected weight loss or is considering a weight loss plan, it may be helpful to learn more from a healthcare provider. They can provide guidance tailored to individual health needs and goals.
