Diagnostic Testing

We use diagnostic testing to uncover imbalances in the body that may be  preventing you from burning fat. This testing includes a comprehensive  blood panel that identifies hormone imbalances, vitamin or mineral  deficiencies, sluggish metabolism, heavy metal toxicities etc. 

We also  offer food sensitivity and allergy testing that may affect weight loss  results. Each week we monitor your progress using cutting edge  technology called the InBody Scale, a Body Composition Analysis to  ensure you are losing fat and not important lean body mass.

Body Composition Analysis

Every week we test your body composition. Weight is just a number. It's  important to know what makes up that number. Fat, muscle, water etc. The  InBody Scale analyzes your complete body composition to determine  exactly how much extra fat you are holding onto or if you have any  muscle deficiencies. It also measures visceral fat, the fat surrounding  vital organs such as your heart and liver, your basal metabolic rate,  lean body mass or muscle and more! 

We use these measurements as our tool of assessment every week during medical weight loss treatment to make  sure you are losing fat and to customize your program depending on your results. This test is included for FREE during your complimentary weight  loss consultation.
