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!

✨ Nutrition guidance is finally catching up to what bodies have been telling us all along.

For years, the focus was on calories, portions, and restriction.

While those tools have their place, they often miss the bigger picture:

👉 how food actually interacts with human biology.

What’s encouraging to see now is a shift toward something our bodies have been telling us for decades —
food quality matters more than numbers alone. 🥗

When we center meals around:
🥕 whole, minimally processed foods
🍎 vegetables & fruits
🍗 quality protein
🥑 healthy fats
🫙 fermented & fiber-rich foods

…we create a foundation that supports metabolism, gut health, immune balance, and long-term resilience.

From a functional lens, this way of eating supports:
✔️ stable blood sugar
✔️ metabolic signaling
✔️ gut microbiome diversity
✔️ immune balance
✔️ long-term resilience

🚫 Less restriction
➡️ More nourishment

And that’s where real, sustainable health changes happen.

It’s about building a foundation your body recognizes, responds to, and can adapt to — with room for individuality.

✨ Real food isn’t a trend.
It’s the starting point.

If you feel like you’re constantly fighting hunger, cravings, or blood sugar swings — this is an important piece most people never hear about.

Your gut bacteria produce short-chain fatty acids (SCFAs) when they ferment fiber.
Those SCFAs help:
✔️ improve insulin sensitivity
✔️ stimulate GLP-1 (your natural appetite-regulating hormone)
✔️ support stable blood sugar after meals

When SCFA production is low, blood sugar becomes harder to regulate — and cravings get louder.

This is why supporting gut health isn’t just about digestion…
it’s foundational for metabolism.

30 minutes. No pressure. Just showing up. 🧘‍♀️

Power yoga in my home gym today—definitely challenging, but in a way that felt supportive rather than depleting. Trying a new Peloton instructor and letting my body move how it needed to.

This is your reminder that consistency doesn’t have to mean max effort every time.

It just has to be intentional.

Movement like this supports:
✅ stress hormone balance
✅ mobility & joint health
✅ builds strength without over stressing the body
✅ improves circulation & lymphatic flow
✅ nervous system regulation
✅ long-term metabolic health

Start where you are. That’s always enough. 💛

Yes — exercise is a stressor.
But it’s the good kind of stress.

When you lift weights or push yourself through a workout, you trigger healthy adaptation. Your body becomes stronger, more resilient, and better able to handle life’s demands. 🙌

But here’s the catch…

It’s not usually exercise that becomes the problem —
it’s chronic, unrelenting stress from things like:

• Chronic dieting
• Overtraining without recovery
• Poor sleep 😴
• High-pressure work
• Family responsibilities
• Nutrient deficiencies
• Gut imbalances
• Lifestyle stressors piling up

This is where cortisol becomes dysregulated — too high, too low, or swinging in between. And that’s when we start to see things like insulin resistance, metabolic issues, inflammation, and fatigue… all of which make midlife feel harder than it needs to.

And during perimenopause, fluctuating hormones put many women into a higher sympathetic (fight-or-flight) state by default. 🧠🔥

That’s why strength training (like deadlifts + pushups 👇) are so powerful when paired with:

✔️ Enough recovery
✔️ Consistent protein
✔️ Quality sleep
✔️ Stress support
✔️ Listening to your body

Every woman is different.

Every day can feel different. What your body needs at 35 may not be what it needs at 45 or 52. That’s not failure — that’s physiology.

Move with intention. Train smart. Support your hormones. And adjust based on what your body is telling you. 💛 I’m always here to help - reach out when you’re ready to take out the guessing and start seeing real results.

🥬 Fresh, crunchy, and takes five minutes to pull together — this Shredded Brussels Sprouts Salad is one of my favorite ways to get more fiber in during the week.

🍋 Shredded Brussels, Parmesan, toasted nuts, apple, cranberries, and a simple lemon-Dijon dressing. That’s it.

⏱️ Holds up for 2–3 days and pairs perfectly with protein for steady blood sugar and better energy.

This time of year hits differently.

More decisions. More planning. More social pressure. And biologically? Your brain is already under a heavier load.

Here’s why winter shuts down your focus faster:

✨ 1. Less sunlight = lower dopamine
Dopamine drives motivation, clear thinking, and follow-through. Shorter days = naturally lower dopamine → faster mental fatigue.

✨ 2. More cortisol fluctuations
Cold temps + holiday stress = unstable cortisol. When cortisol is high or erratic, your prefrontal cortex (decision-making hub) doesn’t fire as cleanly.

✨ 3. Blood sugar swings from holiday eating
More treats, alcohol, and irregular meals = big glucose spikes → brain fog, irritability, and poor focus.

✨ 4. Your nervous system is overstimulated
Noise, travel, parties, gifts, to-do lists, family dynamics… it’s a lot of micro-stress. The brain gets overloaded and defaults to “shut down” mode.

✨ 5. Too many choices = decision fatigue
Your brain burns energy with every choice — outfits, gifts, meals, schedules. Add low sunlight + high cortisol and it hits harder.

So if you feel more scattered, forgetful, or tired — you’re not “failing.” It’s biology + season + stress.

Here’s what helps ⬇️
• Simplify your choices
• Create predictable meals & routines
• Get outside in the morning light
• Support blood sugar
• Set smaller daily goals
• Protect your evenings for unwinding

You don’t need more willpower — you need fewer decisions.

And your winter brain will thank you. ❄️✨

My kids asked for Pico de Gallo last night… in December. 😂

Even though it’s not tomato season, this quick, fresh mix brings so much brightness to winter meals — and it naturally supports digestion + immunity (vitamin C, prebiotics, detox support… yes please).

It’s one of those recipes you can add to your weekly meal plan and use on everything:
🍳 eggs
🥗 salads
🍗 proteins
🌮 tacos
🍚 bowls
…and anything that needs a little fresh lift.

Save this for easy meal prep all season long. 🌿✨

We hear it all the time:

“Fix your hormones.”
“Balance your hormones overnight.”
“This will fix everything.”

But here’s the truth 👇
Hormones can’t be fixed. They can only be influenced.

Hormones are always responding — to your meals, your stress, your sleep, your movement, your blood sugar, your gut, your environment.
They’re dynamic messengers, not switches that someone can flip for you.

And that’s why quick-fix promises often fall short.

Real hormonal support comes from:
✨ stabilizing blood sugar
✨ eating enough protein
✨ lowering stress load + supporting your nervous system
✨ prioritizing sleep
✨ nourishing your gut
✨ supporting detox pathways (liver + lymph)
✨ reducing inflammation
✨ building muscle
✨ addressing nutrient deficiencies
✨ showing up consistently for your body

In midlife especially, your hormones shift hour-by-hour — which means your daily habits matter more than any single solution ever will.

One supportive choice at a time.
You have more influence than you think. 🤍

A little sunshine, warm water, the beach, exactly what I needed.

Taking this week to slow down, breathe, and refill my cup. ☀️🌊

If weight loss has become harder in perimenopause or menopause, it’s not just age — it might be time to check your hormones.

Estrogen, progesterone, testosterone, thyroid hormones, cortisol, and insulin all work together to regulate your metabolism. When even one of these becomes imbalanced, weight loss can feel impossible no matter how hard you try.

Here are the key areas I always check with my clients:
• S*x hormones (estrogen, progesterone, testosterone + DHEA)
• Thyroid health (TSH, Free T3, Free T4, Reverse T3)
• Adrenal function (cortisol rhythm)
• Insulin + blood sugar markers (fasting insulin, Hemoglobin A1C)

Once these are supported, everything begins to shift:
✨ Metabolism responds
✨ Cravings calm down
✨ Energy improves
✨ Sleep gets steadier
✨ Weight finally starts moving

You don’t have to guess your way through this season — I help women uncover the real root causes so they can feel like themselves again. 💛
