Love Yourself More Than Food


Colleen Phillips, Ph.D. has been helping people lose weight and feel good through proper nutrition and diet since 1984.


Colleen custom designs each patient's diet plan, which allows you to include some of your favorite foods in your personalized plan.


Preferably your weight loss should be monitored on a weekly basis or according to your own schedule. We keep track of your weight loss, your blood pressure and your pulse everytime you visit our facility. Meetings are one on one and weekly Vitamin B-12 injections/supplements are offered at no additional cost.


During your first visit you will receive a free consultation with our nutritionist Colleen Phillips and / or one of our caring nurses.


The program will be explained to you in detail and any questions you may have will be addressed at this time. Once you decide to start the program, you will see one of our Board Certified physicians for a medical and physical exam. The physician will then determine your overall health and if you qualify (98% of our patients do qualify) you will be able to begin taking our SAFE, FDA APPROVED DIET MEDICATION.


We also do a blood test to check your Triglycerides and Blood Sugar as well as other tests that might be ordered by the physician. This procedure is repeated annually.
