Is a retreat worth it?

If you’re skeptical, you might be wondering if a retreat can actually make you healthier. According to one recent study, the answer is yes. The study, published in the Journal of Alternative and Complementary Medicine, took place at a wellness retreat with a blend of educational, therapeutic, and leisure activities with a structured diet.

Researchers compared guests’ weight, waistlines, blood pressure, and other measurements at the beginning and end of the retreat, and again six weeks later. They discovered statistically significant improvements that were likely to be maintained after the guests returned home. These findings are consistent with what we do at ThreeHealth.

Our program is guided by the latest scientific research, and a member of our team tracks each guest’s progress individually. We measure body composition, weight, blood pressure, and other markers at the beginning and end of their stay (more frequently if they are current patients). Every guest has different needs and we see them make measurable progress toward their specific goals. Depending on their priorities, improvements may include fat loss, muscle gain, inches lost, lower blood pressure, better sleep, less pain, and lower reported levels of stress.

Maybe you’re wondering if it’s better to plan your own wellness trip and purchase these accommodations and services one-by-one. With ThreeHealth, not only do you end up paying less, you also get built in support, and more individual attention from experts at the top of their field.  Plus, you’ll see improvements, and you’ll leave with resources and a plan for continuing your progress. So, if health is wealth, then a wellness retreat is a wise self-investment that can produce benefits long after you leave.

Is ThreeHealth worth it? According to research, price comparisons, and current/former patients, the answer is a resounding yes.

Experience has taught me that sustainable weight loss affects more than the scale and requires a lifestyle change. Together, my patients and I explore such issues as self-care, priority management, assertiveness, and relationship changes.
