I’m making a matcha latte here, and I actually do like green tea for metabolic health.

One of the active compounds in green tea, EGCG, has been studied for several things including:
🟢supporting fat oxidation
🟢improving insulin sensitivity
🟢influencing estrogen metabolism
🟢antioxidant and anti-inflammatory effects

So yes — green tea can absolutely be a helpful tool.

But here’s the part that gets overlooked.

If someone is dealing with ongoing gut issues, those tools often don’t move the needle very much.

Because when the gut environment is off, the body may also be dealing with things like:
❌chronic low-grade inflammation
❌disrupted hunger and fullness signals
❌blood sugar instability
❌poor nutrient absorption

And those things can make metabolism feel like it’s working against you.

So trying to “boost metabolism” with supplements while the gut is struggling can end up feeling like:
trying to silence the smoke alarm while the fire is still burning.

The alarm isn’t the real problem.
The underlying issue is.

This is why in my practice I often investigate gut health first, especially when someone has both digestive symptoms and metabolism concerns.

Because once the gut environment improves, metabolism work often becomes much easier.

This is exactly why I created It Starts in the Gut, a program designed to investigate and address the root causes behind gut symptoms.

If you’ve been dealing with things like:
• bloating
• constipation
• IBS
• food reactions
• weight loss resistance
your gut might be the place to start.

Enrollment for the guided cohort is open now and registration closes March 31.

Supplements can support metabolism.

Gut first.
Metabolism second.

03/18/2026

One of the easiest ways to influence metabolism?

Walk after meals.
Not a harder workout.
Not another supplement.

Just a simple SIGNAL to your body.

Your metabolism is constantly responding to signals throughout the day.

When you eat a meal, your blood sugar naturally rises. If you stay completely sedentary, that glucose tends to hang around longer in the bloodstream.

But when you walk, your muscles start using that glucose for energy right away.

That one small action sends a signal that helps:
✔️lower post-meal blood sugar
✔️improve insulin sensitivity
✔️reduce energy crashes later
✔️support metabolic flexibility

In fact, human research has shown that short walks after meals improve blood sugar control more than a longer walk done earlier in the day.

Timing matters.

And the best part is you don’t need to turn it into a workout.

Even 10–15 minutes after lunch or dinner can make a difference.

This is the kind of work we focus on inside the Metabolism Discovery Lab — not chasing hacks, but rebuilding the daily signals that help metabolism start working with you again.

Because metabolism isn’t random.
It’s responsive.
And walking after meals is one of the simplest signals you can send.

Your metabolism is always listening.
The question is: what signals are you sending it?

A lot of women come to me feeling frustrated because they can’t lose weight and think it just must be their metabolism.

But once we start talking, they casually mention things like:

“I’m bloated most nights.”

“Sometimes I’m constipated. Sometimes I go too much.”

“I have a lot of gas and thank god my husband doesn’t care.”

“I’m trying to eat more fiber and vegetables, but it seems to make my gut worse.”

And that’s when the conversation shifts.

Because when your gut is struggling, your body is constantly dealing with signals that make everything else harder — including metabolism.

Got gut issues? Then think about this:
❎Chronic low-grade inflammation→ not supportive of a healthy metabolism
❎Blood sugar swings → cravings and appetite chaos
❎Poor nutrient absorption → less fuel for your metabolism
❎Disrupted hunger and fullness signals → making intuitive eating much harder

In that environment, you can eat perfectly and still feel like your body isn’t responding the way it should.

This is why I built It Starts in the Gut®.

Not as another diet or quick fix, but as a structured way to actually investigate what’s happening in your digestive system and address it step by step.

Because once the gut environment improves, a lot of other things start working better too.

The guided cohort is open right now and enrollment closes March 31.🚨

If the group program doesn’t feel like the right fit, I also offer a private intensive option where we do the same work together one-on-one. 👭

A lot of “metabolism problems” are actually gut problems in disguise.🥸

If your stomach gets bigger as the day goes on… this is one of the most common gut patterns I see.

You wake up feeling relatively flat.
By the end of the day your stomach feels tight, swollen, and uncomfortable.

It can feel confusing because you might not even feel like you ate that much.

Here’s what’s usually happening.

As you eat throughout the day, your gut bacteria ferment certain parts of the food you eat. That fermentation produces gas, which is normal. But when the microbiome is out of balance, digestion is sluggish, or bacteria are growing in the wrong places, gas production can become excessive. Instead of digestion happening quietly in the background, pressure starts building and your abdomen can visibly expand as the day goes on.

This is why people often notice:
‼️Bloating that worsens later in the day
‼️Feeling or looking “pregnant” by evening
‼️Gas or pressure after meals
‼️Certain healthy foods making things worse

And the frustrating part is that most people are told to just eliminate foods… when the real issue is the gut environment itself.

This is exactly the kind of pattern we investigate inside It Starts in the Gut.

Inside the program we use advanced gut testing, personalized nutrition strategies, and a step-by-step plan to actually understand what’s happening in your digestive system and how to fix it.

Because if your gut is struggling, everything else becomes harder — including energy, hormones, and metabolism.

Enrollment for the guided cohort of It Starts in the Gut is open right now.

👍 Early bird pricing ends tonight
👍 The program begins April 8
👍 We meet monthly as a group + work together one-on-one

If you’ve been dealing with bloating, constipation, IBS, food reactions, or unpredictable digestion… your gut might be the place to start.

Here’s something I see all the time.

People are trying really hard to improve their health.

They’re buying the supplements.

Trying the products.

Listening to the podcasts.

But the habits that actually drive metabolic health are still chaotic.

Late nights.

High stress.

Alcohol most nights.

Skipping meals.

Blood sugar swings.

Your metabolism responds most strongly to the daily signals you give your body.

Things like:
💤sleep
🍴nutrition patterns
💪muscle mass
✌️stress regulation

Inside the Metabolism Discovery Lab, we focus on those foundations first. (Find more info in the link in my profile)

Because when those are in place, metabolism starts working with you instead of against you.

Metabolism doesn’t change because you bought something.
It changes because you changed something. 🤔

03/09/2026

A theme I see over and over in my practice…

Someone comes to me wanting to fix their metabolism.

They want help with:
🖐️weight loss resistance
🖐️fatigue
🖐️hormones
🖐️blood sugar swings

But when we actually talk about what’s going on in their body, their gut is completely off.

Bloating.

Constipation.

Gas.

Food reactions.

Unpredictable bowel movements.

And here’s the reality…

Inside the Metabolism Discovery Lab, we focus on building metabolism through nutrition, habits, and lifestyle. That work is incredibly effective.

But when gut inflammation or dysbiosis is present, the work becomes much harder.

Because your body is trying to regulate metabolism while the gut is struggling in the background.

Which is exactly why I created It Starts in the Gut®.

A 4-month guided gut healing program where we investigate what’s actually happening in your digestive system and build a strategy to address it.

Because sometimes the real first step isn’t fixing metabolism.

It’s fixing digestion.

And honestly… it also just sucks to feel bloated, constipated, gassy, or uncomfortable every day.

Trying to lose weight should never take priority over addressing symptoms like that.

Inside the 4-month It Starts in the Gut® program, we take a deeper look at what’s actually happening in your digestive system.

The program includes:
👍Gut Zoomer stool testing
👍a personalized strategy to address your results
👍monthly 1:1 sessions with me
👍 a monthly group workshop where we go deeper into gut health topics and normalize what so many people are experiencing

+ Additional testing (like SIBO breath testing) can also be added if we identify that it would be helpful.

The next guided cohort begins Wednesday, April 8.
Our group workshops will be held the first Wednesday of each month at 12:30 PM, and all sessions are recorded if you can’t attend live.

‼️I’m currently offering an early bird rate through the end of the day Friday, March 13, and enrollment for this cohort will close March 31.

If your gut has been asking for attention for a while, this might be your time to finally address it.

Another year older and when you really think about it.. it is a gift.🎁

Some years stick out more than others and this was certainly one for the books. It had to be one of the hardest of my life — physically and emotionally.

From the same week I learned I was pregnant with baby #4, my family also got really really hard news about my father. So it was pregnancy nausea, fatigue, dead of winter yuck, with lots of fear and anxiety hoping he would still be here to meet the baby…to celebrate another birthday together. And with pregnancy alone- you just keep hoping everything continues to go well. Sneaky low level worrying is always there until I’m holding that baby in my arms . This pregnancy was the hardest of them all too. A very pregnant achey tired summer. Lots of hip pain and UNrest. I felt like not fun mom. My sparkle felt faded. Then newborn life with three other kids and starting a brand new school year.

It was a lot. Every single month felt heavy in some way.

My birthday always falls in this weird in-between season — the end of winter but not quite spring. Which honestly feels fitting. I usually feel somewhere between surviving and blooming- often every year at this point.

And now, six months postpartum, I finally feel like I’m coming up for air.
Not in a dramatic way.
Like I’m almost done crawling out of the trenches and seeing light again. ✨

I’m sure my hormones are having an effect too. 🙂

I’m also closer to 40… and I can feel that “I don’t give a f***” energy creeping in 😅… in a good way.

Anyway these are my birthday reflections and ramblings and a lot of feels I’ve been holding in until now when I feel like sharing.

I like sharing because I like when other people can share their stuff and I can relate too.

So I’m just happy to be here!

It seems like life will always throw curveballs. There will always be trenches. But I’ve personally found that growth usually happens when you start crawling out and realize you handled more than you thought you could.

I hope I never forget that and that it does work out that way always.

Grateful for another year.
Grateful for my people.

And very ready for spring 🤍 🌷

I have a very unscientific screening tool I use all the time to screen for cortisol issues.

I don’t start with labs.
I don’t start with supplements.

I ask one question:
“Do you sit down to eat your meals?”

Not what you eat.
Not how many grams of protein.
Just… do you actually sit down?

Because if you’re:
– Skipping meals
– Eating in the car
– Grabbing bites while standing
– Eating while answering emails
– Finishing your kid’s leftovers instead of making your own plate
– Done eating in 3 minutes because you’re rushing to the next thing

That tells me a lot.

And not in a judgmental way.

In a “your life might be running you right now” way.

If you truly cannot find 10 minutes to sit and eat…
You’re probably not just “busy.”
You’re probably in overdrive.

And when someone is living in overdrive all the time, I start thinking cortisol.

I start thinking nervous system.

I start thinking… okay, we need to zoom out.

Because if your body never feels safe enough to slow down for a meal, it’s not going to magically balance hormones, improve digestion, or drop body fat.💡

That’s not how this works

And yes — this absolutely bleeds into gut issues too.
When you’re rushing all day, digestion is not a priority for your body. Survival is.
So bloating, reflux, constipation, weird food reactions… they’re not random. 💩

They’re often lifestyle signals.

I’m not saying this to shame you.
I’m saying it because this is incredibly common.
Especially for moms.
Especially for women 35+. 🙋‍♀️
Especially for the women who take care of everyone else first.

But if you feel called out right now…
That’s your awareness moment.
Not “try harder.”
Not “be more disciplined.”
Just awareness. 🤔

Because before we layer in hormone testing or fancy supplements, we need to ask:
Do you even have space to take care of yourself?

That’s where we start inside the Metabolism Discovery Lab. 🤓
Not with extremes.
With foundations. 💪🥬🫐

DM me for more info. We are just getting started!

If you feel like you’re doing everything to lose weight…

but keep ending up back where you started…

you’re not lacking effort.

You’re stuck in the cycle most women are taught:

Push harder.
Eat less.
Exercise more.
Try the next cleanse.

And while those approaches can create temporary weight loss…

they don’t address the metabolic environment underneath.

Hormones.
Stress load.
Muscle mass.
Blood sugar.
Gut + detox pathways.

So the body resists long-term change.

Inside the Metabolism Discovery Lab, we step off that hamster wheel.🐹

We focus on the systems actually driving weight resistance…

so your strategy finally works with your body — not against it.

Registration is now open if you’re ready for a different approach. ❤️

Dear mom in your 30s (or beyond)…

If your body feels different after kids — I get it.
I’m right there with you.

Four kids later, I’m also in the season of rebuilding…
choosing me again…
figuring out what routines actually fit my life now.

Motherhood changes more than our schedules.
It shifts our stress load.
Our sleep.
Our hormones.
Our nervous system.
Our metabolism.

So it makes sense that the strategies that worked before kids don’t feel the same anymore.

And it’s not about “bouncing back.”

We get finer and wiser with age, don’t we?

Moving forward isn’t about trying to shrink ourselves back into who we were — it’s about building strength, resilience, and support for the body we’re living in now.

For many of us — especially 35+ — this work matters even more.

Because perimenopause is coming…
and metabolic resilience really, really does matter, my friend. ❤️

That doesn’t mean urgency or pressure.
It just means building habits that support:
✅Muscle
✅ Metabolism
✅Blood sugar
✅Hormones
✅Energy
✅Long-term health

Inside the Metabolism Discovery Lab, this is exactly what we focus on — in a way that fits motherhood, not fights it.

No extremes.
No all-or-nothing rules.
Just steady, realistic habit change.

❌You’re not trying to go backward.

➡️You’re building forward — stronger, wiser, and more supported than before.

If you’re over 35, weight loss timelines deserve a reality check.

Not because weight is the only goal…

But because expectations have gotten wildly disconnected from physiology.

Inside my work, we don’t chase fast scale drops.

We focus on fat loss, muscle preservation, and metabolic stability.

Because when weight drops quickly, it’s rarely just body fat.

It’s often:

❌Muscle
❌Water
❌Glycogen
❌Nervous system stress
❌Hormonal disruption

Which is why fast loss so often leads to rebound gain later.

When someone is in a fat loss phase, a general pace we might see is:
5 – 1 lb per week

And over time, that can look like:

3 months: 6–12 lbs
6 months: 12–24 lbs
9 months: 18–36 lbs
12 months: 24–48 lbs

Not because faster isn’t possible…

But because slower loss is more protective of metabolism and muscle.

Now — context matters here.

Not everyone is trying to lose a large amount of weight.

And not every body will lose at the same pace.

For example:

✨Someone with more weight to lose may see faster shifts initially
✨Someone closer to their set point may see slower, subtler changes
✨Some phases focus more on recomposition than scale change at all

And that’s not failure — that’s physiology.

This is why we don’t measure success by the scale alone.

We look at:

✅Body composition
✅Strength gains
✅Measurements
✅Energy
✅Hormonal markers
✅Metabolic health

Because the goal isn’t just a lower number…

It’s a body that feels stronger, more regulated, and more resilient long-term.

Especially heading into perimenopause and beyond.

So if your progress feels “slow” compared to what diet culture promised…

It might actually mean your body is doing it the sustainable way.

And if you want guidance navigating that without panic or extremes —

That’s exactly what we do inside the Metabolism Discovery Lab.

✨ We finally got to meet the littlest member of our family… and if you didn’t know—it’s a BOY! 💙
