[Exciting News]: The Precision Nutrition Method now validated in 3 peer-reviewed research studies.


Here at Precision Nutrition we know that our coaching methods help clients lose fat, build strength, and improve their health. Now, with the publication of 3 peer-reviewed research studies, the rest of the world does too.


I recently got some really exciting news — news that’s both good for Precision Nutrition and for anyone who’s registered for (or is considering registering for) one of our programs.

Three research papers have just been published in peer-reviewed journals confirming the safety and effectiveness of Precision Nutrition’s methods, which drive our Coaching, Certification, and ProCoach programs.

Why is this so awesome?

Well, although we know that our coaching methods work to help people lose fat, build strength, and make vast improvements to their health (we’ve proven it with more than 45,000 of our own clients)…

…people outside Precision Nutrition sometimes remain skeptical, especially those in the evidence-based communities (including medicine, pharma, etc).

Not only do these peer-reviewed studies show *very* positive results (as you’ll see); they also demonstrate that our coaching program is truly “evidence-based.”

Study #1: A personalized, multi-platform nutrition, exercise, and lifestyle coaching program: A pilot in women.

In one study, done in conjunction with Dr. Maggie Watt, a Precision Nutrition Coaching graduate and physician from Victoria, BC, we studied a group of overweight/obese women in her practice.

Particularly, we looked at how Precision Nutrition Coaching influences:

  • weight,
  • waist circumference,
  • fat mass,
  • muscle mass,
  • blood pressure,
  • total cholesterol,
  • and other factors.

The results were very exciting.

Over 12 months, women who completed the program:

  • lost an average of 16.5 pounds
  • reduced waist circumference by an average of 3.4 inches
  • decreased diastolic blood pressure by 3.33 mmHg
  • increased high-density lipoproteins by 0.14 mmol/L

In conclusion, the women who completed Precision Nutrition Coaching experienced significant weight loss (8.3% of initial body weight) coming mostly from body fat. Chronic disease risk factors also improved.

Study #2: Commercially available lifestyle modification program: randomized controlled trial addressing heart and bone health in BRCA1/2+ breast cancer survivors after risk-reducing salpingo-oophorectomy.

The second study was done in conjunction with Dr. Shannon Lynch and Dr. Kathryn Schmitz, both Precision Nutrition Coaching grads, and researchers at the Perelman School of Medicine at University of Pennsylvania and the Fox Chase Cancer Center in Philadelphia.

Here we studied female breast cancer survivors who underwent prophylactic oophorectomy (the preventive removal of the ovaries) and thus experienced premature surgical menopause. We examined:

  • cardiovascular fitness,
  • dietary intake,
  • leisure time activity,
  • body composition,
  • bone mineral density,
  • bone structure,
  • muscle strength.

Again, really positive results.

Average adherence to the program was 74.8%, and those who completed it:

  • maintained their fitness (1.1%) while the control group decreased (−4.0%),
  • gained bone area (0.5) while the control group decreased (−0.8),
  • decreased BMI (−4.7%) and fat mass (−8.6%) while the control group only lost lean mass.

In conclusion, in this population at high risk for negative bone and cardiovascular outcomes, Precision Nutrition Coaching preserved cardiovascular health, improved bone health, and decreased weight through fat loss.

Study #3: Evaluation of a Web-based Weight Loss Intervention in Overweight Cancer Survivors Aged 50 and Younger.

The final study was again done in conjunction with Dr. Shannon Lynch and Dr. Kathryn Schmitz (mentioned above) and looked at young male (testis) and female (breast) cancer survivors. We examined:

  • weight loss,
  • body fat percentage,
  • BMI,
  • waist-to-hip ratio
  • retention rates
  • adverse events.

Again, exciting results. Men and women who completed the program:

  • lost an average of 17.8 pounds,
  • lost 9% of their initial body weight,
  • decreased their BMI by 2.5,
  • lost 3.5% body fat.

In conclusion, as half of adult cancer survivors under the age of 50 are obese and struggle with weight loss, this study demonstrated that Precision Nutrition Coaching can help this population experience clinically significant decreases in body weight, body fat, and BMI.

In the end, these three studies confirm what we know to be true:

Research-driven personal nutrition coaching (using our unique habit-based methodology) produces life-changing results in clients of all ages, dealing with all challenges, and from all walks of life.

The “secret” is out — and I can’t wait to see what our method can do for the tens of thousands of new Precision Nutrition Coaching, Certification, and ProCoach clients to come.


Want help becoming the healthiest, fittest, strongest version of you?

Most people know that regular movement, eating well, sleep, and stress management are important for looking and feeling better. Yet they need help applying that knowledge in the context of their busy, sometimes stressful lives.

Over the past 18 years, we’ve used the Precision Nutrition Coaching method to help over 100,000 clients lose fat, get stronger, and improve their physical and mental health… for the long-term… no matter what challenges they’re dealing with.

It’s also why we work with health, fitness, and wellness professionals (through our Level 1 and Level 2 Certification programs) to teach them how to coach their own clients through the same challenges.
