Weight loss pills are supplements designed to help people lose weight by boosting metabolism, reducing appetite, or preventing fat absorption. They can be a helpful addition to a healthy diet and regular exercise routine. Some pills work by increasing energy levels, making it easier to stay active, while others help control hunger, so you eat fewer calories. Popular ingredients include green tea extract, caffeine, and L-Carnitine, which support fat burning and digestion.  While weight loss pills and liquids can provide extra support, they work best when combined with healthy lifestyle habits.Â
