For weight loss and blood sugar control, use stevia in place of sugar and artificial sweeteners in baking, and flavouring drinks and foods. It is a natural calorie-free sweetener, so you can use it as a sugar substitute without getting the calories of refined white sugar or the potentially harmful side effects of chemical sweeteners like aspartame. Also, people report that taking 15 to 20 drops of stevia before meals makes them eat less because they feel less hungry, so stevia may also work as a natural appetite suppressant.
