Ranked Arizona’s #1 Physician for Weight-Loss Management

“I have been a patient here for a few years. Dr. Knighton & his staff go above & beyond caring for me. They detected my thyroid issue & got it under control. Along with managing my weight. They truly care & take pride in their patients. You’re family here & you feel it the second you walk through the door” –Kelli

A Fitter, Slimmer, Healthier You

Now you CAN finally get the results you’ve always wanted!

A ‘leaner, slimmer you’ is the promise of innumerable diets, health club contracts, pre-packaged ‘meals ready to eat,’…but often the results don’t really justify the cost or commitment. The body simply responds to the new activity or diet by ‘adapting’ itself to these new realities and the “costly solution” doesn’t work or the patient even gains weight.

Individualized Programs

Virtually all of the weight-loss programs in our society fail the individual because those programs target a rapid loss of weight, rather than assist the individual to lose weight in a healthy manner with the end goal of keeping it off for a lifetime. One of the reasons for the failure of most programs stems from the lack of addressing the metabolism and only focusing on starvation. You can’t just simply starve someone for a period of time and expect the body to want to cooperate, long term. The body’s number one priority is to survive, and the lesson the body learns through starvation is only to store more unwanted weight. Starvation and gaining weight doesn’t seem all that appealing, now does it?

Arizona Medical Weight Loss Group Shot


Dr. Knighton uses a comprehensive program for the treatment of overweight patients where nutrition and exercise are based on the individual’s blood type. When indicated, Dr. Knighton will monitor and oversee the medical treatment and the use of FDA-approved prescription medications (I.e. phentermine, phendimetrazine, and/or diethylpropion). A physician-supervised medical weight loss program may be the safest and wisest way to not only lose weight but maintain the weight loss long-term.
