How You Can Personalize Your Weight Loss Plan Through DNA Testing

By Stephanie E - Jenny Craig

Reviewed by Briana Rodriquez, R.D.


The internet is exploding with diet buzzwords: keto, counting calories, macronutrients, BMI — it’s enough to make anyone’s head spin! If you’ve racked up a long list of diets that haven’t worked, it might be time to get a little personal. Enter DNA testing for weight loss, a new way to personalize your weight loss experience on a deeper level. So, how is it different from other diets you’ve tried? We’ll explain.


We have paused our weight loss insights plan for now. In the meantime, stay healthy and check out our new meal delivery options.

What is genetic testing for weight loss?

Unlike one-size-fits all weight loss options, a DNA-focused weight loss meal plan is shaped by the results of a genetic test. 

If you’re wondering if a low-carb diet, low-fat diet, or something that strikes a balance between the two could work for you, a DNA test could help you find an answer.



“Genetic testing can help to explain more about your unique DNA and what weight loss strategies may work best for you,” explains Dr. Mark Sarzynski, Ph.D., FAHA, FACSM, Director of Genomics Research at a genetics-based health management company. “DNA gives you a unique opportunity to try a plan that may be better matched to your body.”

What this means: Based on your DNA, you may benefit from following one type of weight loss plan over another. 

What can your DNA tell you about weight loss?

First, a quick refresher on genetics. Remember that twisted ladder shape from your science textbooks? That’s DNA. DNA is found in most of your body’s cells and holds a complex “recipe” of biological information that tells your cells what to do.1

Genes are the keys that may help to shed light on your experiences with weight loss. They’re segments of DNA responsible for individual characteristics that you’ve inherited from your parents.2 Humans share the same genes, but not all of them are expressed, or “turned on.”



“If your DNA test results suggest you’re likely to be overweight as an adult, that doesn’t mean you’re destined to become overweight. However, your likelihood of becoming overweight may be greater than someone who doesn’t have that genetic profile,” says Sarzynski. 

For many DNA-based weight loss programs, including Jenny Craig's, all you’ll need to do is a simple cheek swab. 

What you’ll find out from your DNA test results can vary. Programs with the best DNA testing for weight loss can provide details about weight loss-specific genetic markers and give you a recommended menu plan, plus resources to help support your efforts. You’ll find each of these elements — and more — with Jenny Craig’s new plan.



Jenny Craig’s DNA weight loss plan: What will your results reveal?

If you’ve had trouble losing weight before, getting a better understanding of your genetic tendencies could help. 

Jenny Craig’s DNA weight loss plan is a unique tool to help optimize your results and includes a detailed report with tips based on each of your genetic markers.

A meal plan tailored to your results

Based on how you’re likely to processes protein, fat and carbs, you’ll follow one of three recommended meal plans, explains Briana Rodriquez, Registered Dietitian Nutritionist at Jenny Craig. 

What are the meal plan options?

“Following a low-fat diet shouldn’t mean you have to avoid eating foods that contain healthy fats, while following a low-carb diet shouldn’t make you cut out carbs completely,” Rodriquez says. “Even though the meal plans can be lower in carbs or fat to help with weight loss, we make sure food groups aren’t eliminated.”


  • Balanced — If your body is likely to process all three macronutrients (carbs, proteins and fats) normally, you’ll follow this meal plan. 
    • The Balanced meal plan emphasizes: A mix of fiber-rich carbohydrates, lean proteins and healthy fats.


  • Low-Carb — If your body is likely to process carbohydrates less efficiently, you’ll follow this meal plan.
    • The Low-Carb meal plan emphasizes: A variety of complex carbs, including non-starchy vegetables and other good sources of dietary fiber, plus lean proteins and healthy fats.


  • Low-Fat — If your body is likely to process fats less efficiently, you’ll follow this meal plan.
