In my 19 years as a nurse, I've seen the word “detox” mean very different things. I've cared for patients going through medically serious withdrawal, and I've also watched the wellness world turn “detox” into everything from juice cleanses to supplement protocols.
Those are not the same thing.
And after trying my own over-the-top version of a “gut reset,” I learned something I wish more people understood:
Your body already has a detox system.
Your liver and kidneys are working around the clock to process and eliminate waste and other substances your body doesn't need. And while a well-designed reset can be a helpful way to step back, simplify your habits, and hit the refresh button, the bigger goal is supporting the systems that are doing this work every single day.
So before we talk about detoxing, here's the question I want you to think about:
Are your daily habits supporting your body's natural detoxification systems—or are they continually adding to the workload?
Because that's where things get really interesting.
THE CORE SCIENCE
Here's the truth: a healthy liver and healthy kidneys are already detoxifying your body continuously. That's their full-time job, every hour of every day, and they're remarkably good at it.
But that doesn’t mean our daily habits are irrelevant. What happens when those organs are dealing with a heavy, chronic load — inflammation, oxidative stress, excess sugar, environmental toxins, poor sleep, and a diet of mostly ultra-processed food? That's where things start to shift.
YOUR LIVER UNDER CHRONIC LOAD
Excess sugar gets converted to fat and stored directly in liver cells. This is the driving mechanism behind fatty liver disease (now called MASLD), which is currently the most common liver condition in the U.S. — and it's tied closely to diet and insulin resistance.
Left unaddressed, that fat accumulation can progress to inflammation, and over time, scarring.
Chronic oxidative stress depletes glutathione, one of your liver's key antioxidants and a central player in how it processes and clears substances. Glutathione is one of the body's important antioxidant defenses and plays a role in several processes involved in how the body handles certain compounds. Oxidative stress can affect glutathione availability, which is one reason overall metabolic and nutritional health matters.
Your gut and liver are directly connected — inflammatory compounds from an imbalanced gut travel straight to your liver through the portal vein. This is part of why gut health and liver health are so tightly linked.
YOUR KIDNEYS UNDER CHRONIC LOAD
Chronically elevated blood sugar is the leading cause of kidney disease worldwide. Over time, it damages the tiny filtering structures inside your kidneys.
Chronic high blood pressure causes similar damage to the blood vessels your kidneys depend on to filter properly.
Both organs have a lot of reserve capacity, which means real damage can be building for years before bloodwork or symptoms catch up. That's part of why this kind of burden is often called "silent."
HOW A RESET CAN HELP
A well-designed reset can be valuable: it temporarily lowers the load. Eating fewer ultra-processed foods, limiting alcohol and added sugar, staying hydrated, and emphasizing whole foods can reduce some of the dietary and metabolic stressors your body is dealing with. That reduction in load helps calm inflammation, supports a healthier gut, and gives those organs room to catch up rather than just keep up. It's creating a healthier environment for the systems that are already doing the work
Clearing space so your body can get traction can make it easier to build the daily habits that matter long-term. That's the real value of a reset: not a dramatic cleanse, but a reset button that makes it easier to get on track and stay there.
WHY YOU MIGHT FEEL WORSE BEFORE YOU FEEL BETTER
Headaches, fatigue, irritability, and other symptoms can happen when you abruptly change caffeine, alcohol, food intake, or hydration. It can be a little uncomfortable (this is temporary as your body adjusts). This is usually a combination of caffeine or sugar withdrawal, your blood sugar recalibrating, dehydration, electrolyte shifts, and your gut microbiome adjusting to new inputs.
Feeling significantly unwell isn't something you should automatically interpret as ‘toxins leaving your body.’ If symptoms are severe, persistent, or concerning, it's worth talking with a healthcare professional.
SUPPORTIVE WAYS TO GIVE YOUR BODY A HAND
Some of my favorites:
Water, water, water. Your kidneys need adequate fluid to filter well, and dehydration makes everything harder.
Warm water with lemon in the morning. Simple, hydrating, and many people find it genuinely soothing for digestion.
Cruciferous vegetables (broccoli, cauliflower, Brussels sprouts, cabbage) — these support your liver's natural detoxification enzymes and help replenish glutathione.
Fiber — helps move waste through your colon efficiently instead of letting it sit. Increase intake slowly.
Sleep. Your body does a huge amount of its repair and clearance work while you sleep.
Moving your body. Movement supports circulation, muscle function, metabolic health, and regular bowel movements.
Reducing alcohol, ultra-processed food, and added sugar — less for your liver and kidneys to process.
ONE THING I PERSONALLY LEAN ON
There is a reset I've personally used and found supportive when I want to hit refresh:
A 3-day gut reset called Reboot, which I personally love for giving my digestion a gentle break and some extra support.
There is a recommended food plan to follow while doing it, which I think is an important part of the process. I put together a simple guide to help you follow the plan.
Interested in the guide? Just reply to this email and I'll send it your way.

As always, this is something I've personally used—not medical advice or a recommendation that you need a detox or cleanse
🌿 FAITH CORNER
There's something beautiful about the idea of renewal — of the old being cleared away to make room for something better.
"Create in me a pure heart, O God, and renew a steadfast spirit within me." — Psalm 51:10
Our bodies were designed with incredible built-in systems for restoration — a liver that filters, kidneys that cleanse, a body that knows how to heal itself when we give it what it needs. I think that's a reflection of a God who also specializes in renewal. He doesn't just want to help us feel better physically. He's always doing the deeper work too, if we let Him.
Your body was designed to thrive. Sometimes it just needs the right building blocks to remember how.
With faith, science, and wellness,
