Marnie Lawler - Functional Nutritionist

Marnie Lawler - Functional Nutritionist As a Functional Nutritionist my goal is to help attain optimal health by uncovering the root cause of your symptoms using functional testing.

What Is Health was created out of a true desire to help people live life to their fullest potential. I am passionate about empowering my clients to regain their health through diet and lifestyle changes... everyone should be given the ability to achieve their personal goals. My approach comes from my Functional Nutrition Training and my Personal Experience dealing with adrenal fatigue, gut issues

(a parasite and low enzyme output), hormonal imbalances (estrogen dominance), brain fog, fatigue and several anemia’s (iron, B-12, folate and B-6). By changing my own diet, performing diagnostic testing and addressing my stressors, I have been able to overcome these issues. But, it took me a VERY LONG time. I would like to make this easier for everyone, NO ONE should have to struggle the way I did, for as long as I did. I specialize in digestive disorders, thyroid and autoimmune and conditions and hormonal issues. Through a combination of customized nutrition, laboratory testing, and high quality targeted supplements, we’ll work together to restore your body’s balance and vitality. What does that mean? To begin with, generic diets and protocols have their place, but they rarely take you the distance. They are not targeted to the unique person that you are, and they do not honor your bio-individuality. Let’s face it, that’s why when your best friend discovers a diet that works for her, does not create the same results for you. You have your own set of circumstances, biochemistry and unique physiology that comes into play. Often, in order to determine what your body needs, I lean on lab testing – using only what gives us the most pertinent information. This will be used to sculpt a diet and healing protocol that gives your body exactly what it needs and removes anything that’s getting in the way of your healing. This is challenging work, no doubt, and I understand that when I ask you to make modifications to your diet or daily activities to get results, you are the one who has to make the hard changes. But I promise, as my slogan says, “Your Health, My Mission,” I will be by your side to help guide, be your support, your troubleshooter and cheerleader! Nothing will be left unturned to get to the root of your issues, and you will NOT BE ALONE!

I started running when I was 13 years old.

Over the past 40 years, running has taught me a lot about discipline, consistency, and what the human body is capable of.

But it has also taught me that doing the same activity over and over can create movement compensations.

As runners, many of us become quad-dominant. We rely heavily on our hip flexors, quads, and calves, while our glutes, hamstrings, and core don’t always contribute as much as they should.

The truth is, being active doesn’t automatically mean we’re moving well.

Simple exercises like heel slides, glute activation drills, balance work, and core stability exercises help me maintain better movement patterns and address some of the imbalances that can develop over time.

They may not look exciting, but they’re often the exercises that make the biggest difference.

Because fitness isn’t just about doing more.

It’s about building a body that moves well, stays resilient, and allows you to keep doing the activities you love for years to come. 💪

There was a time when I thought healthy eating meant thinking about food all day.

🤔 What should I eat?

🤔 Did I eat too much?

🤔 Should I start over tomorrow?

🤔 Why am I still hungry?

Many people live with that constant mental chatter, what is now commonly called *food noise.*

The truth is, food noise is rarely a willpower problem.

It can be a sign that your body is underfed, underslept, overstressed, lacking structure, or simply trying to compensate for habits that aren’t supporting your physiology.

As a Functional Nutritionalist, I’ve found that food thoughts often get quieter when we focus on the basics:

🥩 Adequate protein

🍽️ Consistent meals

😴 Better sleep

💧 Hydration

🧘 Stress management

📝 A simple, realistic plan

When the body feels nourished and supported, nutrition decisions often become easier.

✨ You don’t have to white-knuckle your way through fat loss.

✨ You don’t have to spend every waking moment thinking about food.

✨ And you certainly don’t need to be perfect.

The goal isn’t simply eating less.

The goal is creating a body and lifestyle that no longer requires food to take up so much mental space.

Food noise doesn’t get quieter because you try harder.

It often gets quieter because your body finally has what it needs. ❤️

The American College of Sports Medicine recently updated its resistance training guidelines for the first time in 15 years, reviewing:
✔ 30,000+ studies
✔ 130+ systematic reviews
✔ 30,000+ participants

And the message is clear:

Strength training matters for:
→ mobility
→ metabolic health
→ mitochondrial function
→ independence
→ longevity

After age 30, we naturally begin losing muscle mass, and that decline accelerates with age if we do nothing about it.

The good news?

You do NOT need complicated workouts.

✔️ Free weights.
✔️ Resistance bands.
✔️ Machines.
✔️ Bodyweight exercises.

All can be effective.

Healthy aging isn’t just about living longer.

It’s about maintaining the strength and energy to fully participate in your life. 💫

We often focus on exercise, but what about the fuel that powers it all? 🏋️‍♀️

Your body is constantly rebuilding itself. 🌱

Every cell, hormone, enzyme, muscle fiber, and neurotransmitter is made from the nutrients you provide it. 🧠

The food you eat today becomes the body you have tomorrow. 🍎

Exercise is important. I believe in moving your body, building strength, challenging yourself, and staying active for life. 💪

But no amount of exercise can replace the nutrients your body needs to function, recover, repair, and thrive. ✨

When you focus on quality protein, colorful fruits and vegetables, healthy fats, fiber, and nutrient-dense foods, you’re giving your body the raw materials it needs to do its job. 🥗🍗

Your body is always listening. ❤️

The question is: what message are you sending it with your food choices? ❓

You’re doing everything “right,” and still not seeing results,. Here’s why. 👇

Cold plunges. Fasting. HIIT. Sauna. All things we’re told are good for us.

And they can be.

But what I see constantly in my practice are women checking every wellness box and still feeling exhausted, bloated, and stuck.

The reason? They’re stacking stress on top of an already stressed body.

There’s a concept called hormesis, the idea that a small amount of stress helps the body adapt and get stronger. Lift weights, muscles grow. Fast a bit, metabolism gets more flexible. Makes sense.

But here’s what nobody talks about: your body can only adapt if it has the capacity to adapt.

And most of the women I work with? They’re already beyond that capacity before they ever add the cold plunge.

When I walk through a client’s day it often looks like this: coffee first, fast until noon, intense workout, low-calorie eating, always on the go. On paper it looks disciplined. Physiologically, it’s a constant stress signal to an already taxed body.

That’s when the symptoms show up… worse sleep, anxiety, bloating, weight gain despite “doing all the things they are seeing or being told they should be doing“ and hormones are completely off.

This isn’t a willpower problem. It’s a capacity problem.

Before we add more stress, we need to build the foundation: enough protein, stable blood sugar, better sleep, digestion support and a healthy gut microbiome, adequate hydration, vitamins and minerals. Then, and only then, can we layer in the hard stuff strategically.

The goal isn’t to push harder. It’s to build resilience.

If this sounds like you, there’s usually a reason things aren’t working, and it’s rarely about doing more.

It’s finally warming up around here ☀️

And if you’re working out more, walking, running, hiking, or just spending more time outside… you’re probably sweating more too 💦

More sweating = more electrolyte loss.

This is one reason I use LMNT daily.

Not just for sweating, but because it can also help support:
✔ Workouts + recovery
✔ Hydration
✔ Sauna use
✔ Running + hiking
✔ Low-carb lifestyles
✔ Higher-protein diets

When we sweat, we lose more than just water.

We also lose important minerals like:
• Sodium
• Potassium
• Magnesium

And honestly… I would say a large percentage of the clients I run blood work on show signs of being underhydrated.

Low electrolyte levels can sometimes contribute to:
• Headaches
• Fatigue
• Muscle cramps
• Brain fog
• Low energy during workouts
• Changes in blood pressure and heart rate

This is something I see often with active clients who are eating “healthy,” drinking lots of water, but still not feeling great.

Hydration is not just about water.
Minerals matter too.

I’ve been using it regularly for workouts, hydration, sauna use, and higher-protein days… especially as the weather gets warmer and sweat loss increases 💦

Take 5 minutes to stretch it out. 🧘‍♀️

Did you know the general rule of thumb is that you should stretch *twice as much* as you work out? Say what?! 😳

Even if you don’t work out regularly, your body still needs movement and mobility work.

Think about it…

Most of us spend hours:
➡️ Sitting in cars
➡️ Working at desks
➡️ Looking down at phones
➡️ Carrying stress in our bodies all day long

Over time, this can shorten muscles, limit mobility, restrict circulation, and set us up for aches, pains, stiffness, poor posture, and injury.

Just a few minutes of stretching each day can help:

❤️ Improve blood flow and oxygen delivery
❤️ Reduce stiffness and tension
❤️ Support joints and mobility
❤️ Improve posture and alignment
❤️ Help keep the body moving well as we age

I do mobility work before every workout, and yoga at least twice a week has become one of the best things I do for my body.

As we age, strength training is important… but maintaining mobility matters too. 💪💫
