Weight loss treatment

Is often extremely difficult; minimal success rates

Should ideally involve both diet and exercise

Requires permanent, substantial lifestyle changes; minimal evidence of long term success

Utility of drugs/supplements or surgery; strictly complementary to lifestyle changes

How can drugs promote weight loss?

Decreasing appetite, increasing metabolism, inhibition of fat tissue, blocking absorption of calories, reducing reward/cravings for specific foods, decreasing meal size (make you feel fuller faster)

To perform these functions, drugs may act in the CNS or the digestive tract

Health at Every Size (HAES)

Weight loss doesn’t have to be a goal; instead, the idea is to support people in adopting healthy habits for the sake of health and well-being (rather than weight control)

Recognizes that health and fitness can exist at all sizes
