Nutrition and Lifestyle Education

CHIP_Logo_RGB_MedTransComplete Health Improvement Program (CHIP)

We chose the Complete Health Improvement Program (CHIP) for our nutrition and lifestyle education program because CHIP is a premier lifestyle intervention targeting chronic disease.  The program is well suited for clinical, corporate, and community settings. The short-term and long-term clinical benefits of the intervention, as well as its cost-effectiveness, have been documented in more than 30 peer-reviewed scientific and medical journals.

Impressive Clinical Outcomes

The CHIP intervention has consistently demonstrated positive outcomes, helping people prevent, arrest, and reverse their chronic diseases. It has been described by the American College of Lifestyle Medicine as “achieving some of the most impressive clinical outcomes published in the literature.”

Dr. Hans Diehl

The CHIP intervention was founded by Dr. Hans Diehl in 1986.  Dr. Diehl developed CHIP as an affordable 30-day lifestyle intervention. Currently, an estimated 60,000 people have participated in the program in more than 350 cities across North America, the United Kingdom, Australia, and New Zealand.

Stop the “Good Life” from Killing Us

CHIP not only shows us why we need to make better lifestyle choices but also how to, as Dr. Diehl says, stop the “good life” from killing us.  It is not natural to be obese and hypertensive, have high cholesterol and triglycerides, and to suffer from diabetes, constipation, heartburn, angina, or heart disease. Seventy-five percent or more of our Western diseases are “lifestyle-related,” according to the U.S. Surgeon General. [1] These diseases are connected to our processed foods; lack of exercise; overuse of cigarettes, alcohol, and caffeine; increased levels of stress; and inadequate support systems.

Scientifically Proven to Prevent, Arrest, and Reverse Disease

CHIP is scientifically proven to prevent, arrest, and reverse chronic and complex diseases. It is ideal for people who have multiple high-risk factors and a burning realization that they need to be proactive and responsible for taking charge of their own health. Studies show that CHIP participants with the highest risk factors, who apply themselves, achieve near-normal biomarkers. [2]. This is the power of lifestyle medicine.

An Engaging Scientific Journey

The CHIP program is an engaging, highly entertaining scientific journey into the causes and consequences of our present “state of health.”
CHIP’s 19-session program is designed to reduce disease risk factors by improving dietary choices, enhancing daily exercise, increasing support systems, and decreasing stress.

The vast majority of participants lower their LDL cholesterol, blood pressure, and blood sugar levels, as well as reduce excess weight.

The CHIP Program


CHIP’s educational program is presented as eighteen 45-minute video lectures, each combined with a class discussion.

At the start of the program, a comprehensive health screen is conducted to establish risk factor levels for each participant. Health screen results are provided to each participant early in the program.

Reduced Requirements for Medications

After modifying their lifestyle, many CHIP participants experience reduced requirements for their medications. During this transition, participants are encouraged to maintain regular follow-up visits with Dr. Harlin or their subspecialty physicians.

CHIP Results

On average, CHIP participants obtain the following results:

  • 19.8% reduction in total cholesterol in 30 days for those with baseline cholesterol of higher than 280mg/dl (7.24 mmol/l)
  • 19.9% reduction in fasting plasma glucose in 30 days for those with baseline fasting plasma glucose of higher than 125mg/dl (6.94 mmol/l)
  • 3% reduction in BMI within just 30 days
  • ideal body weight with long-term adherence to the lifestyle

Before and After Biomarkers

Immediately following the program, the health screen is repeated. A detailed report is prepared for each participant that compares their biomarkers before and after the program. Reports and course completion certificates are presented at the end of the program. See more details in the Program Outline.

Our CHIP graduates provide mutual support and help each other sustain adherence to the program guidelines through our educational support group get-togethers.

Endorsed by PCRM and CSPI

CHIP is endorsed by the Physicians’ Committee for Responsible Medicine (PCRM), and the Center for Science in the Public Interest (CSPI).
