This article is intended to help people choose the products that are appropriate for them. I will try to stay focused on the specific products for losing weight, and not confuse you with others, or leave you with a list of options you don't need.
Weight loss products are used by millions of people. They are also marketed by medical professionals, dieticians and anyone who wants to lose weight. Some weight loss products contain substances that are called "weight loss drugs" (or sometimes weight loss supplements) to help you lose weight. These drugs work by slowing your metabolism, which in turn increases your appetite, making it easier to eat larger amounts of food. Weight loss drugs also make it easier for you to stop eating and maintain a healthy weight, or to go on a diet, but they are not used as a cure for obesity.
The Food and Drug Administration (FDA) has very strict regulations on the marketing of weight loss products and does not approve new weight loss products without adequate safety studies. You need to have a doctor's prescription before you can buy weight loss drugs.
You will also need to go to a doctor who is registered with the FDA to give you medical advice about your medical condition and to give you prescription drugs to take for weight loss. These doctors must have a degree in dietetics, physiology or medicine.
