Obesity and Metabolic Program

Obesity is a chronic, progressive, relapsing – but treatable disease. Over the past two decades, the obesity rate in the United States has increased from 30% of individuals to 42%. It's projected that by the year 2030, over 50% of our country's population will be obese. This is an alarming statistic, but one that can be reversed.

Treating obesity requires a comprehensive, individualized approach. The team at St. Luke’s Obesity and Metabolic program believes that one size does not fit all when it comes to treating obesity. The approach your family member, neighbor, or co-worker used may not be what works for you. Our goal is to design a treatment plan specifically for you.

For more information or to schedule an appointment, please call our team at (208) 381-3915 and select option 3.

Pillars of Intervention and Opportunity

  • Nutrition

    We'll review your current eating habits and help you construct a nutrition plan that works with your lifestyle and supports your health goals.

  • Physical Activity

    Based on your individual ability to exercise, we'll help you slowly work up to an optimum level of activity that will allow you to reach your goals.

  • Medication

    We'll review your current medications and identify if any of your current medications can contribute to weight gain. We'll also review if anti-obesity medications may be right for you and your treatment plan.

  • Behavioral Health

    We'll assess if stress, depression or other mental health issues may be impacting your ability to reach your goals. We'll also examine your sleep habits, which contribute to your overall health and our ability to successfully treat obesity.

What to Expect

  • Your First Visit (45-60 minutes)

    We'll start by discussing your journey with obesity. Next, you'll be asked to do some homework prior to your next visit: track your food intake for 2-3 weeks, get metabolic lab work, and complete health questionnaires about your goals.

  • Your Second Visit (45 minutes)

    We'll review your homework and begin developing an individualized nutrition and physical activity plan. We'll also start discussing potential medications, sleep hygiene, and stress reduction techniques.

  • Follow-up Visits (30 minutes)

    Follow-up visits generally occur once every four weeks. At these visits, we'll monitor your progress and partner with you to decide if any adjustments may be necessary. We'll also track your response to anti-obesity medications, if applicable.
