Determining the "best" medicine for fast weight loss is complex and depends on individual factors, medical history, and tolerance to side effects. Several FDA-approved medications can aid weight loss, but their effectiveness varies from person to person. These medicines should be used in conjunction with lifestyle modifications such as diet and exercise. Here's an overview of some weight loss medications:
