Adult Obesity Clinical Guideline
Quick Guide to Obesity
Definition: Obesity refers to abnormal or excessive fat accumulation that may impair health.
• 36.5% adults in the U.S. are obese.
• Weight loss in overweight/obese adults is
associated with decreased mortality.
• All patients who would benefit from
weight loss should receive counseling on
lifestyle changes and goals for weight
loss.
• A comprehensive lifestyle intervention
(combined diet, exercise, and behavioral
treatment) is the most important
strategy for weight loss.
• Pharmacologic and bariatric treatments
are recommended for consideration only
after diet and exercise weight loss
attempts have failed.
Evaluate for underweight
Causes: Obesity is the result of an imbalance between calories consumed and calories
burned. This is often caused by an increased intake of calorie-dense foods along with limited
physical activity.
