Weight loss drugs are designed to help people who are classified as obese lose weight. Weight loss drugs should only be used in those who:

  • Are morbidly obese;
  • Have a BMI above 30 and have failed to lose weight with a lifestyle program; or
  • Have a BMI above 27 and have risk factors already present.

Weight loss drugs can be classified into 3 broad categories:

  • Drugs that decrease food intake;
  • Drugs that alter the metabolism of food; and
  • Drugs that increase thermogenesis.
