Overweight is a condition of excessive fat deposits, while obesity is a chronic complex disease defined by excessive fat deposits that can impair health. Both conditions can lead to various health risks such as type 2 diabetes, heart disease, bone health issues, reproduction problems, and increased risk of certain cancers. The management of overweight and obesity includes dietary modification, behavioral interventions (such as exercise), medications, and surgical intervention if necessary. A low-carb diet, high in protein, has been shown to be effective for weight loss compared to other types of diets like the Atkins diet.
