Jenny Craig’s DNA Decoder Plan™ will analyze 15 different markers that will provide you with insight into your body’s genetic predisposition surrounding five key areas:

  • How Your Body Processes Food
  • How Your Body Responds to Exercise
  • Your Sleep Duration
  • Your Eating Behaviors
  • Your Metabolism

Based on your individual results, Jenny Craig will recommend the best weight loss plan to help maximize your weight loss efforts. But your meal plan is just the beginning — your personal weight loss consultant will guide you along this weight loss journey and be there to support you every step of the way. With the help of science-backed strategies, you and your consultant will work as a team toward your ultimate goal: weight loss and better health. Once you review your results with your consultant, you will get started on a weight loss plan that is tailored to work with your DNA results and fit your lifestyle.

With the DNA Decoder Plan you’re unlocking the secrets to your genetic code to find out what genetic variants influence the way your body absorbs, metabolizes, and uses different dietary components. Scientists have found that specific genes guide how the body processes dietary components such as carbohydrates, fats, proteins, micronutrients, etc. So, while your genes may predispose you to weight gain, understanding your genes empowers you to adapt your diet and lifestyle for a better chance at weight loss success. Your DNA report will reveal what you need to know about your metabolism, sleep habits, eating behaviors, exercise and nutritional needs. Most important, your personal consultant will provide you with a personalized menu plus action plan to help you maximize your weight loss success. Your menu plan - plus action plan - is tailored to your individual DNA results and fits your lifestyle. Jenny Craig will provide strategies to overcome genetic tendencies and simple solutions to overcome hurdles associated with your genetic profile. By following the plan, you are empowered to make choices that may help maximize weight loss efforts. Please see our full terms & conditions here.

The first three markers indicate how your body is predisposed to process carbohydrates, fats and proteins. Although everyone needs to consume a variety of these macronutrients, not everyone processes them the same way. Find out how your body is genetically predisposed to processing each of these foods — and the best meal plan that may help to maximize your weight loss success.

The 4th, 5th and 6th markers are how your body is predisposed to respond to different exercise routines. While changing your diet will greatly impact your weight loss success, exercise is another component that is essential to living a well-rounded, healthy lifestyle. These genetic markers predict what should be the best exercise routine for your body that may help to accelerate your weight loss efforts. Plus, you’ll learn about how your genetics play a role in your natural motivation to exercise (or lack thereof).

The 7th marker deals with sleep based on your genetics. Duration of sleep may impact your weight and other health risks and can set you up for better health now and in the future.

Markers 8 through 11 will predict different eating behaviors such as your likelihood to overeat, mindlessly snack and your taste preferences – as well as how likely you are to feel satisfied after a meal.

Markers 12 through 15 deal with your metabolism including your resting metabolic rate, your tendency to regain weight and your genetic risk to be overweight.

How It Works

If you receive your kit from your consultant in-person at your Jenny Craig center, he or she will help register the kit online for you. Next, follow the simple instructions on the label to complete your test in the Jenny Craig center with your consultant. Once complete your personal consultant will mail it for you. Your DNA will be analyzed in a lab and the results will be sent directly to your personal consultant who will use the findings to create a personalized menu plus action plan for your weight loss success.

If you receive your kit via mail the first thing you should do is register the kit at jennycraig.com/registerdnakit. Next, follow the simple instructions on the label to complete your test in the comfort of your own home. Once complete you will send it in the postage-paid envelope. Your DNA will be analyzed in a lab and the results will be sent directly to your personal consultant who will use the findings to create a personalized menu plus action plan for your weight loss success.

To register your kit please visit: https://www.jennycraig.com/registerdnakit. You will be directed to log into or register your account on jennycraig.com. Make sure to use the email address associated with your account. You will then be required to enter the Kit ID Number, which is the 12 digit code on the back of the envelope. Last, click “Register” and you are done.

The best way for the lab to obtain sufficient quantities of DNA for the analysis is through a cheek cell swab sample. This offers a convenient and non-invasive method for DNA sample collection as compared to hair and blood samples.

Your kit contains four DNA collection swabs and we require that you use all of them. Taking one swab at a time, open your mouth and rub the swab firmly back and forth and up and down on the inside of your cheeks. To collect enough cheek cells, be sure to rotate the swab and rub for a full 30 seconds.

To prevent collecting excess saliva, please avoid the gum area. Once the swab is complete, hold and wave the swab for 60 seconds until it dries, then place it directly in the DNA sample envelope.

Repeat with the remaining swabs and place all of them in the envelope as well.

Once complete, seal the pre-paid envelope and mail it. The sample envelope has a barcode that aligns with your kit’s registration number for identification.

With the DNA Decoder Plan kit you will get your results in less than 2 weeks.


Jenny Craig will not share or sell your individual-level information to any third party or to a third party for research purposes. We do not share customer data with any public databases. We will not provide any person’s data (genetic or non-genetic) to law enforcement, regulatory authorities, an insurance company or employer unless required by law to comply with a valid court order, subpoena or search warrant. When a DNA sample is processed, information is de-identified and made completely anonymous to the laboratory. Our lab partners are under contract and strictly follow security and confidentiality obligations to follow all applicable privacy laws as well as meet the obligations of conforming to our Privacy Policy. Kits come with a unique identification number. When a kit is registered online, the kit number is linked directly to the client through our internal database. Our lab partners can only see the kit number, not our customer's names, and they cannot process any samples if they are not registered with the assigned kit number. We safeguard all DNA analysis in accordance with industry standards and access is restricted on a limited basis. Besides the customer, only Jenny Craig authorized personnel will have access to individualized DNA results for the sole purpose of interpreting the data and providing guidance for the next steps in the Plan. Your DNA sample will be destroyed once the analysis is completed. Jenny Craig may only share aggregate, de-identified (anonymous) information with third parties for our business purposes. See the full Jenny Craig Privacy Policy for more information, available at jennycraig.com/privacy.

The first thing technicians do with each new sample is scan the barcode on it, because, for privacy reasons, that's the only identifying information the laboratory has. Next is the DNA extraction and analysis. Once a sample has been successfully analyzed, the laboratory sends the resulting data through a processing program which interprets your data. This analysis is then returned to your Jenny Craig consultant who will work with you on reviewing the results and providing you with a comprehensive and personalized menu plus plan of action.
