What Is Nutrition Response Testing?

In its simplest terms, the idea of Nutrition Response Testing is based on a proven theory that your body knows what’s wrong with it.

In terms of your weight loss journey, it offers you the potential to get to the root of your struggles to achieve your goal weight.

But how is it actually done?

At HealthierU, we’ll start by examining your symptoms to get to the root cause of your problem.

Next, we’ll huddle with you to develop a plan to keep your health-related ailments from returning— for good.

Nutrition Response Testing is the difference between taking pain medication to alleviate the symptom of lower back pain versus identifying the cause and implementing a plan to prevent it from coming back.

It’s the complete opposite of traditional medicine because Nutrition Response Testing does not mask your symptoms with antibiotics.

Instead, it works with your body to uncover the underlying issues that are causing your symptoms to surface.

Nutrition Response Testing offers your body the chance to convey what is going wrong so that you can determine the right way to answer.

How Does Nutrition Response Testing Work?

At HealthierU, the first thing we will do to help you move towards your weight loss goal is perform a Nutrition Response Testing assessment and work up a program.

Every Nutrition Response Testing program looks and works differently because everyone’s body looks and works differently, too.

Unlike popular weight loss programs or diets, your Nutrition Response Testing program is not one-size-fits-all.

This means yours will be custom-designed to suit your specific needs and to meet your goal — in this case, weight loss.

Your initial assessment will be like a non-invasive discovery meeting for your organs.

Your doctor will work to identify the ones that aren’t functioning properly, and are likely the root cause of your symptoms, by monitoring the strength of a specific reflex while in contact with them.

How strong your reflex is is a direct reflection of the health of the corresponding organ in your body.

When you have a...

  • Food sensitivity
  • Nutrient deficiency; or
  • Toxic substance

...your organs become weakened and your doctor will be able to see that in your neurologic reflex.

Next, we’ll work to pinpoint the exact stressor inside your body.

Here at HealthierU, we do this by monitoring your reflex strength while you hold the potential stressor in your hand.

We’ll test substances by having you hold close to 200 small glass bottles, one at a time.

Each one will contain a different substance that could be the underlying cause of your weight loss struggle.

A few substances we’ll test for include:

  1. Toxic metals — Think mercury and aluminum or everyday chemicals like chlorine from drinking water
  2. Parabens from everyday household items like soaps, lotions, and shampoos.

At HealthierU, we also want to test for food sensitivities in addition to these substances.

Common food sensitivities we test for include:

  • Gluten
  • Wheat
  • Eggs
  • Milk

...on top of immune-compromising properties like:

  • Bacteria
  • Fungi
  • Viruses
  • Parasites
  • Mold

You will then receive a program designed for you and only you that includes...

  • Nutrition
  • Whole food supplementation; and
  • Lifestyle recommendations

...that will help your body to heal itself and progress you towards your weight loss goal.

Keeping in mind that everyone’s body will respond differently, you can expect a somewhat common timeline for results.

Most patients who adhere to their programs can begin noticing positive changes within just 4-6 weeks.

Some will take less time, and others will take more, all depending on their symptoms, the severity of the issue and a myriad of other factors.

The most important thing is that you don’t wait — Nutritional Response Testing could give you the answers you need to have to be able to safely and healthily lose weight.

Is Nutrition Response Testing Real?

Understanding how it works and taking the jump to try it yourself are two different things.

Now, you might be wondering, “ Does Nutrition Response Testing really work?


Nutritional Response Testing works as a non-invasive system of analyzing the body to determine the underlying causes of ill or non-optimum health.

It may be that you have an underlying health condition that needs to be addressed before you begin to see progress.

Nutrition Response Testing lets us identify and understand the root cause of your health-related symptoms and addresses the issue, or issues, at hand— naturally.


Your body will give us, and you, the answers to your weight loss struggles.

Solve those and you're well on your way to achieving your goal as a healthier version of you.

Does Nutrition Response Testing Work For Weight Loss?

You’ve tried it all before.

Maybe you’ve experimented with:

But you’re still struggling to hit your weight loss goal.

You have exercised, maybe daily, maybe 3-5 times a week, but nothing is working.

You’ve tried:

  • Yoga
  • Running
  • Spin classes
  • Boxing
  • Barre

And still, nada.

You’re frustrated. The last thing you want to try is another failed weight loss program.

So why exactly is your weight loss journey causing you so much turmoil?

Why Even The Most Popular Diet And Exercise Plans Aren’t Working

The first thing that you need to know and realize is that your struggle to lose weight is not your fault.

There is something going on in your body that is out of your control.

No matter...

  • How hard your try
  • How dedicated you are to your diet or program
  • How much of your life you change to fit your new lifestyle

...nothing is going to work. But not for your lack of effort.

A program from a personal trainer or nutritionist is “one size fits all” and the reason it is not working for you is because it can't —based on your potential health issues.

But knowing that diets and workouts aren’t working and understanding why they aren’t working are two very different things.

Especially when your doctor is stumped as well.

So why is Nutrition Response Testing any different?

When you meet with a Nutrition Response Testing practitioner, you’ll review all the possible diet and lifestyle factors that could be causing your symptoms .

The most important part is truly identifying the root cause of your weight loss struggles and making a plan to overcome them.

Read on to understand how Nutritional Response Testing might be the key to unlocking your weight loss goals.

Why Nutritional Response Testing Is Different Than Other Weight Loss Methods

...HealthierU can help.

If you’re looking to not just lose the weight, but keep it off — permanently — HealthierU is your answer.

HealthierU’s Approach To Nutrition Response Testing


Because we know that every single body is different, the weight loss programs we develop are too.

As a patient of HealthierU, you would receive a customized lifestyle plan, designed ( just for you ) to improve your health in a realistic and enjoyable way.

We start with a Nutrition Response Testing assessment. This assessment is a noninvasive technique that assesses how your...

  • Organs
  • Glands
  • Muscles
  • Tissues

...all function.

This allows us to be able to determine the underlying cause of your weight gain or inability to lose weight.

Once we are able to determine the underlying cause, we develop a one-of-a-kind program, including everything from:

  • Diet
  • Whole food supplementation; and
  • Exercise

...for you to follow.

It’s vital for you to know and understand that unhealthy eating and lack of exercise isn’t always the cause of weight gain or an inability to lose weight.

By using Nutrition Response Testing, we are able to assess the issue and get to the root cause of what is getting in your way.

But when it comes to non-food related symptoms, there are some common culprits.

A few of the most popular weight loss issues can include:

  1. Hormone imbalance: This can affect fat storage, metabolism, and appetite.
  2. Toxic chemical overload: Comes from food, skincare products, and household cleaners.
  3. Toxic metal overload: An overload of mercury, lead, copper, cobalt, and more.
  4. Fungus overload: Often caused by things like bladder infections, chronic respiratory problems, and frequent antibiotic use.
  5. Medications: Including antidepressants, anti-anxiety, insulin, beta-blockers, and others.
  6. Digestive dysfunction: Caused by an unhealthy gut or lack of digestive enzymes.
  7. Consistent stress/lack of sleep: Poor or unattended self-care can lead to physical ailments and affect your mental and physical well-being.
