Serenity and Fire with Krista

Peptides are suddenly everywhere and if you’ve ever googled BPC-157 or TB-500 after a stubborn injury, you already know how fast the advice turns into chaos. One link promises “miracle healing,” another warns you to stay away, and even doctors don’t always agree. We slow the whole conversation down and give you a clear way to think, so you can make decisions with curiosity and caution instead of h...

GLP-1 medications are everywhere, and for people who have fought their weight for decades, the results can feel like someone finally turned down the volume on cravings and “food noise.” I’m Krista Guidenti, and I’m equal parts fascinated and cautious.

Do you feel exhausted, overwhelmed, anxious, unmotivated, or like you've simply lost the version of yourself you used to know? You're not alone. Many people assume fatigue, weight gain, mood swings, brain fog, poor sleep, low libido, and declining energy are simply a normal part of aging. But what if your body is trying to tell you something deeper? In this episode of Serenity & Fire...

Creatine has a branding problem. And it's time we talk about it. Despite being one of the most researched supplements out there, creatine is still largely seen as a "gym bro" thing — and most women have never been told it might actually be for them. Today we're changing that. I'm breaking down what creatine actually is, why women tend to have lower stores of it, and why th...

You can do everything “right” and still feel completely exhausted. The supplements. The workouts. The clean eating. The sleep tracking. And yet… you still wake up tired, overstimulated, and running on fumes. In this episode, we’re talking about something so many people are quietly experiencing right now: a nervous system that never truly gets a chance to rest. Because scrolling in bed isn’t recove...

Sometimes letting go of something is the most strategic thing you can do. In this episode, Krista opens up about the decision to close her lash and brow studio — what looked good on paper, what changed behind the scenes, and the emotional reality of walking clients and staff through a final chapter with care and integrity. Alongside Keri Croft, the conversation expands into what it really takes to...

In this episode, Krista shares the story behind closing her Deka Lash franchise — a decision that, from the outside, might look like failure, but from the inside was about clarity, responsibility, and protecting what matters most.

Networking has a reputation for being fake, awkward, and exhausting. But what if that’s not actually true… what if we’ve just been doing it wrong? In this episode, Krista kicks off a new mini business masterclass series by unpacking one of the most misunderstood — and most powerful — tools in business: networking. This isn’t about handing out business cards or forcing small talk. It’s about gettin...

Your body knows the truth… even when the label doesn’t. If you’ve ever eaten something labeled “high protein,” “keto,” or “clean” and still felt hungry, tired, or craving more — this episode is for you. We break down processed vs ultra-processed foods in a way that actually makes sense, including:  • Why “healthy” labels can be misleading  • How ultra-processed foods impact cravings, energy, and s...

Your “healthy” grocery cart might be doing more damage than you think… and it’s not just because something is labeled “processed.” In this episode of Serenity & Fire , I’m breaking down one of the most misunderstood topics in modern nutrition: processed foods vs ultra-processed foods.

The truth, as always, lives somewhere in the middle. In this conversation, I break down what seed oils actually are, how they’re processed, and why they’ve become such a hot topic. We talk through the real concerns — including...

This episode was inspired by a Women’s History Month panel discussion called Women Who Build , where I was invited by Telhio Credit Union to reflect on leadership, entrepreneurship, and what it really means to build something that lasts. As I reviewed the panel questions, I realized they weren’t just questions for a stage conversation. They were the kinds of questions every founder and leader shou...

There are seasons in business and in life where you’re carrying things you simply can’t explain publicly. Not because you’re hiding anything, but because leadership requires restraint, maturity, and discretion. In this solo episode, I’m sharing what it really looks like to lead under pressure. The invisible weight that comes with growth. The high-stakes conversations. The personnel dynamics. The a...

Do synthetic fibers release microplastics? And how do you evaluate everyday products without spiraling into wellness anxiety? Clean living today can feel chaotic. Labels say “natural” and “clean,” but indust...

After Valentine’s Day, I found myself thinking less about romance and more about connection. The kind that fuels teams, strengthens relationships, and determines whether a business actually thrives. In this episode of Serenity and Fire , I’m sharing what happened at our annual Panacea Luxury Spa leadership retreat in Florida and how one simple relationship exercise exposed hidden tension, built de...

Over the last few episodes, we’ve talked a lot about sugar, fasting, insulin, and metabolic flexibility. And at some point, the question naturally comes up:  " Okay… but what is my body actually doing?" In this episode, I’m sharing what I learned from my own blood work, and more importantly, how to look at labs from a place of understanding instead of anxiety. This isn’t about chasing pe...

In this episode of Serenity & Fire, Krista breaks down fasting without the chaos. From intermittent fasting to 24-hour fasts and beyond, she explains how fasting actually works in the body and how to choose the right approach based on your metabolism, hormon...

This is the final episode in the Serenity and Fire sugar series—and today, we’re bringing everything together. Over the past few episodes, we’ve unpacked what sugar actually does to your body and brain: how it impacts glucose and insulin, why cravings aren’t a willpower problem, and why fat loss can feel blocked even when you’re “doing everything right.” In this episode, we move from information t...
