Weight–loss medications work in different ways. Most either suppress your appetite or reduce your body’s ability to absorb fats from food. Certain antidepressants, diabetic, and anti-seizure medications are sometimes prescribed to aid weight loss too.
Eating more often can help you lose weight. When you eat large meals with many hours in between, your metabolism slows down between meals. Having a small meal or snack every 3 to 4 hours keeps your metabolism cranking, so you burn more calories over the course of a day. The most effective way to lose weight and keep it off is by eating a healthy low-calorie diet and being more physically active.
