Weight loss may significantly decrease the severity of and risk factors for obesity-related diseases. Obesity is not defined by a single cause, but rather a range of contributing factors, including energy imbalance, genetics, inactive lifestyle, lack of sleep, health conditions, medicines, age, and emotional factors. The OPTIFAST Program succeeds because it treats the whole patient, focusing on more than just weight. Our goal is to provide patients with expert resources to address, modify and support lifestyle, behavior and diet decisions. .
