Every body is different, and DNA testing allows us to identify how your genetic makeup affects your energy consumption and metabolism. Your gene variants code for how your body works to process nutrients, as well as your power and endurance potentials. Identifying these variants helps determine what routine will allow you to most efficiently lose weight. With this knowledge of your genetic profile, Dr. Cristy Thomas, DNP, FNP-BC, APRN will develop a customized program that will meet your unique needs for weight loss and overall health.


  • Weight Loss Nutrition Type
  • Micro-nutrient Ratios

Weight Loss Nutrition Type

DNA testing allows Dr. Thomas, DNP, APRN to determine your weight-loss nutrition type based on the amount of each macronutrient your body needs for optimum weight loss. Things that might affect which nutrition type you fall into include carbohydrate and saturated fat sensitivity and lactose and gluten intolerance risk. Based on your genetic profile, Dr. Thomas, DNP, APRN will identify which of the following four weight-loss nutrition types you belong to:

Fitness● This weight-loss type aims to increase the body’s capability to distribute inhaled oxygen to the muscles through increased physical exercise.

Mediterranean● This type focuses on a heart-healthy eating plan based on Mediterranean-style diet.

High-Fat● This weight-loss nutrition type follows a high-fat, low-carbohydrate diet that burns fat in the body for energy rather than carbs.

Low-Fat● Low-fat nutrition types consume a diet of low-fat and moderate-carbohydrate foods, making it easier to cut calories and lose weight.

Micronutrient Ratios

Macronutrients are components of food that are needed for energy, growth, and other important bodily functions. The three primary macronutrients are proteins, carbohydrates, and fats.

How our bodies process these macronutrients is genetically predetermined, so DNA testing identifies your nutrition type to determine your ideal macronutrient ratios (what percentage of your diet each macronutrient should make up). These ratios help Dr. Thomas, DNP, APRN to develop a nutrition plan to speed up your metabolism and help you lose weight efficiently.



DNA testing allows Dr. Thomas, DNP, APRN to provide you with a personalized menu to optimize your weight loss. Once she understands which food types your body processes and converts to energy most efficiently, she can develop a meal plan utilizing your ideal nutrient ratios to achieve weight loss and increased energy.


There are many different exercises out there, and Dr. Thomas, DNP, APRN can develop a personalized exercise program based on your genetic potential to get the most effective results for your body.


DNA testing gives you insight into how your body works and what conditions you are more susceptible to. This information is important for weight loss as well as lifestyle changes you can make to improve your overall health and well-being.



Women gain weight during pregnancy, and it can be difficult to get back down to their pre-pregnancy size after giving birth. DNA testing can identify exactly what their bodies need to lose weight.


People who have resolved to lose weight but don’t know where to begin can greatly benefit from DNA testing. Rather than suffering the frustrations of failed attempts at fad diets, people who know their genetic profile and weight-loss nutrition type can immediately begin an effective weight-loss regimen that is tailored to their individual needs.


Many people on a weight-loss journey reach a point where they cease to lose weight even though they are following a routine that was previously effective. DNA testing reveals the body’s specific needs so you can adapt and improve your routine and continue losing weight.


How is DNA testing performed?

A simple saliva sample is used to gather your genetic material and test for the variants of the genes you carry. It takes approximately 15 minutes to collect the saliva sample in our office. We provide you a private room where you can provide the sample, and the rest of the work is done by our office.

How do my genes affect weight loss?

Your gene variants determine how your body works to process nutrients and how it responds to exercise. Some people may have sensitivities to particular food components, such as carbohydrates, saturated fat, salt, and caffeine, or have lactose or gluten intolerance risks. Factors such as these affect your body mass index, body fat accumulation, insulin secretion, and carbohydrate metabolism, which affect how easily you lose or gain weight. DNA testing identifies these as well as your macronutrient intake needs to help Dr. Thomas, DNP, APRN formulate an effective weight-loss plan.

How long after testing will I have my results and customized weight-loss program?

The testing takes approximately three weeks because your sample is sent to the lab where they perform all the genetic testing and analysis. In the meantime, while we wait for your test results, this is a great time to start one of our weight loss programs for the month or to complete our 10-day or 28-day detox program so that your body is fit and ready to excel your weight loss.

Will I have a follow-up with Dr. Thomas, DNP, APRN after I am given my diet and exercise program?

Dr. Thomas, DNP, APRN always requests that her patients return for a follow-up appointment within four to six weeks. At this appointment, she will evaluate whether the program is working effectively or if any adjustments need to be made to achieve more effective results. Patients can also request an appointment any time they wish to discuss their program further.

Is the cost of DNA testing covered by insurance?

Yes, DNA testing is covered by most medical insurances, including Medicare, and most commercial insurance plans cover DNA testing. Each patient is required to meet with Dr. Thomas, DNP, APRN. If we determine that you meet certain qualifications and that genetic testing will benefit your treatment program, DNA testing will be done and ordered the same day. For insurance plans with high deductibles, there are some financial assistance programs available that can limit your copay. We can discuss your insurance options during your appointment.
