Why Chronic Disease Starts Years Before Symptoms Appear

Here’s something most of us never get told: Chronic disease doesn’t start the day you get a diagnosis.  It usually starts years — sometimes decades — earlier.

Which explains a lot, doesn’t it?  Because almost everyone I talk to says some version of: “But I felt fine… until I didn’t.” 

I know I felt fine when I got my cancer diagnosis.  I had no idea.

The “light switch” myth

We tend to think disease works like a light switch:

• Off → On

• Healthy → Sick

But that’s not how the body works.  It’s more like a slow dimmer switch.  Things quietly shift long before symptoms show up:

• Blood sugar creeps up

• Inflammation hums in the background

• Blood pressure inches higher

• Cholesterol patterns change

• The gut gets less diverse

• Stress hormones stay elevated

And because none of this hurts yet, we assume everything is fine.  (Our bodies are very polite that way.)

Let’s Take a Quick pause - and notice this:

Which of these sounds familiar (even if labs are “normal”)?

▢ Low energy

▢ Poor sleep

▢ Blood sugar swings

▢ Digestive issues

▢ Mood changes

▢ Feeling “off” but not sick

These are often early signals, not failures.  If you’re reading this and thinking, “That explains a lot,” you’re not imagining things.  Chronic disease often starts years before symptoms, driven by stress chemistry, inflammation, and gut health shifting quietly in the background.

Just so you know, I created a free, gentle 7-day food plan to support those systems early — without dieting, detoxing, or fixing yourself.

I see this all the time

People often tell me: “My labs were only a little off.”“My doctor said we’d just watch it.”“I didn’t feel sick.” And that’s exactly the point.

With my cancer, initially it was fine, and we watched it for many years until - it was not fine anymore.  But this came with no real symptoms.

Early chronic disease is quiet.

By the time symptoms show up, the process has usually been underway for a long time (often 10–20 years, depending on the condition).

What the science actually shows

Chronic disease develops in stages.  Research consistently shows that conditions like:

• type 2 diabetes

• cardiovascular disease

• metabolic syndrome

• fatty liver disease

develop gradually, with measurable biological changes appearing years before diagnosis (Tabák et al., 2012; DeFronzo et al., 2015).

For example:

• Insulin resistance can exist 10+ years before diabetes

• Atherosclerosis (plaque buildup) begins in youth and early adulthood

• Chronic inflammation often precedes symptoms

The body whispers before it screams.

Inflammation is a big part of the story

This is probably not news to you.  Chronic, low-grade inflammation doesn’t usually cause pain you can feel — but it changes how cells behave.

It’s been linked to:

• insulin resistance

• cardiovascular disease

• cancer progression

• neurodegenerative diseases

(Libby, 2002; Furman et al., 2019)

And yes — diet, stress, sleep, and movement all influence inflammation.

Why waiting for symptoms is a problem?

By the time symptoms show up:

• systems are already strained

• habits are harder to undo

• interventions often become more aggressive

This is why prevention isn’t about being “perfect.”It’s about supporting the body early, while it’s still flexible.

The good news (this part matters!)

Here’s the hopeful part:  Because chronic disease develops slowly,small changes made earlier can have a big impact.  This isn’t about fear. It’s about timing.

What actually helps (no extremes required)

🌿 1. Eat in patterns, not rules

Whole-food, plant-forward dietary patterns are associated with:

• lower inflammation

• improved insulin sensitivity

• better cardiovascular markers

(Katz & Meller, 2014; Satija et al., 2016). You don’t need perfection, just a reliable default.

🚶 2. Move your body regularly

Movement improves:

• glucose uptake

• blood pressure

• inflammatory markers

Even walking counts. A lot.  (Ekelund et al., 2016)

😴 3. Sleep and stress are not “extras”

Poor sleep and chronic stress increase:

• insulin resistance

• inflammation

• cardiometabolic risk

(Mullington et al., 2009). Rest is biology, not laziness.

🦠 4. Feed your gut

Fiber-rich foods support gut bacteria that help regulate:

• immune function

• inflammation

• metabolism

(Mayer et al., 2015)

Your gut is not just for digestion — it’s a control center.

What I wish more people understood

Chronic disease is not a sudden failure.

It’s usually the result of:

• years of small signals being ignored

• environments that push us toward stress and convenience

• systems that wait for numbers to get “bad enough”

This isn’t about blame.  It’s about earlier support.

Want a gentle place to start?

If you don’t want to wait for symptoms to get louder, this free 7-day plan is a calm place to start. It focuses on food patterns that support the nervous system, gut health, and steady energy — the foundations that often shift long before diagnosis.

👉 Get the free plan here: Click Here

(It’s called the 7-Day Serotonin Reset — but think of it as nervous system support, not a reset.)

It’s designed to:

• calm stress chemistry

• support gut-brain health

• stabilize energy and mood

• gently shift food patterns without restriction

No detoxes. No tracking. No food guilt.

Big takeaways (save this)

✔ Chronic disease starts years before symptoms

✔ Early changes are often silent

✔ Inflammation plays a central role

✔ Small, consistent habits matter

✔ Support works better than panic

Cancer Risk, Inflammation & Diet:What the Evidence Really Shows

A few years ago, I did “everything right” (at least on paper). I was eating a mostly whole-food, plant-based diet. I was moving my body. I was trying to live the wellness life.

…and I still got diagnosed with cancer.

That moment taught me something I really needed to learn:

Food is powerful — but it’s not magic. Diet can lower risk and support the body, but it can’t guarantee outcomes. (And if anyone tells you otherwise, please back away slowly.)

Remember, I am a geeky scientist by training (and genetics! LOL) so, let’s talk about what the evidence actually shows about inflammation, diet, and cancer risk, without fear, without fluff, and without turning meals into a moral test.

I’ve also included the scientific sources at the end of this blog so you can read the actual peer-reviewed published study for yourself.  I’m all about empowering you to form you own conclusions which helps supports and motivates you in your health and wellness journey.

First: What is inflammation (in plain English)?

Inflammation is your body’s alarm system.

• Short-term inflammation (like healing a cut) = helpful.

• Long-term low-grade inflammation = can be a problem.

Chronic inflammation can create a body environment that supports cancer development and progression over time (it can affect DNA damage, immune function, and cell growth signals). (You’ll see this reflected in major cancer prevention reports and biomarker research.) [1][2]

A common blood marker for inflammation is C-reactive protein (CRP). I always include this blood analysis when I have blood work done.  It’s covered by most insurance so you may want to ask your medical professional to include it in your annual checkup blood work. 

Higher CRP is linked with higher risk of worse outcomes (including cancer-related outcomes) in large analyses, though it’s not the only factor and doesn’t prove cause by itself. [2]

What the evidence says diet can do

1) Diet can reduce cancer risk, especially through patterns

Cancer prevention science isn’t about one “superfood.” It’s about patterns you repeat.

The World Cancer Research Fund (WCRF) emphasizes a pattern of:

• whole grains, vegetables, fruit, beans

• limiting fast foods/ultra-processed foods

• limiting red and processed meat

• limiting alcohol

• staying active and keeping a healthy weight

  
  

  …as core cancer prevention recommendations.[1]

In other words: It’s probably everything you’ve heard before – but it’s all scientifically backed recommendations. How can we ignore this?

2) Ultra-processed foods are consistently linked with higher risk

Ultra-processed foods (UPFs) aren’t just “food that comes in a package.” They’re industrial formulations, often with additives, emulsifiers, refined starches/sugars, and low fiber.

A major BMJ umbrella review (2024) found UPF exposure was associated with many adverse outcomes, including cancer outcomes in the overall evidence map (observational evidence; not proof of causation). It’s one of the most comprehensive “big picture” summaries we have right now. [3]

A separate 2023 systematic review found consistent associations between higher UPF intake and risk of overall and several cancers (including colorectal and breast), again largely from observational studies. [4]

Translation: This doesn’t mean you’re doomed if you eat chips. It means your everyday pattern matters, and reducing UPFs is a powerful lever.

3) Processed meat has the clearest “avoid/limit” cancer signal

This is one of the strongest, clearest statements in nutrition science:

The International Agency for Research on Cancer (IARC/WHO) classified processed meat as carcinogenic to humans (Group 1) based on sufficient evidence that it causes colorectal cancer.[5][6]

This doesn’t mean “a bite of bacon = cancer.” It means the evidence is strong enough that public health organizations recommend limiting it. [1][5]

Despite the overall evidence, I continue to see tons of ads on TV, magazines and even on cooking shows regarding cooking and consuming known human carcinogens like hotdogs and especially bacon.  This isn’t meant to be a moral judgement, (but it may sound like a judgement anyway) it confounds me that a parent can feed their child a known carcinogen and then be up in arms when they find out that some industry is spraying apples with pesticides or that there is a gas station a mile from their house and they are worried that the fumes can cause cancer for their kids. 

An industry spraying apples or the location of a gas station close to your home may not be in you direct control. Feeding your child bacon is definitely and completely in your control.  If you have gotten this far in my blog – and thank you for that! – then please give this one statement some serious thought.

Okay, back to not judging or stepping down from my soap box.

4) Fiber-rich, plant-forward eating is consistently protective

If you have read any of my blogs or have attended any of my nutrition or cooking classes you know this is a BIG topic for me.  It’s basically the only message that I share that would benefit you the most.  Fiber is not glamorous. Fiber is not trendy. Fiber does not have good PR.

But fiber is quietly one of the most consistent diet factors linked to better long-term health, including lower cancer-related mortality risk in meta-analyses. [7]

Fiber also supports gut bacteria that produce helpful compounds (like short-chain fatty acids), which can influence inflammation and gut barrier integrity, two things that matter for long-term health. [8]

5) Anti-inflammatory patterns (like Mediterranean-style) show benefits

Mediterranean-style diets (plant-forward, lots of fiber, nuts/olive oil, legumes, fruits/veg) have evidence for reducing inflammatory markers in randomized controlled trials (stronger type of evidence than observational studies). [9] I do need to emphasize that consumers have locked in on the olive oil part and less on the fruits, vegetables and nut part.  Also, these studies show that lifestyle plays a big role too.  Less stress, more walking or physical exercise and, this is another big one, community.

I won’t get into it here, but there are a ton of studies out there showing high consumption of pure vegetable oils is one of the main culprits in inflammation.  100% fat, highly processed, minimal nutrient value and absolutely no fiber. The fat on your lips goes straight to your hips. I’ll talk about that another time. Stay tuned. Or message me if you want more info.

Back to my original topic.  Meta-analyses (which is a comprehensive review of the peer-reviewed scientific published literature on this topic) continue to report associations between higher Mediterranean diet adherence and lower incidence for certain cancers (effect sizes vary by study and cancer type). [10][11]

If “anti-inflammatory eating” sounds vague, think:more plants, more fiber, fewer ultra-processed foods, less processed meat, less alcohol. [1][3][5]

What diet doesn’t do (and this matters)

 Diet does NOT guarantee cancer prevention.  Even with excellent habits, cancer can still happen due to:

• genetics

• random mutations

• environmental exposures

• hormones

• infections

• age

• and factors we don’t fully understand yet

So, if you’ve ever looked at someone’s diagnosis and thought, “But they were so healthy…” yes. Exactly. Healthy habits are not a shield of invincibility. They’re risk reducers and body supporters. [1]

The “Do This This Week” Action Plan (simple + powerful)

✅ 1) Add a fiber anchor daily

Pick one:

• ½ cup beans or lentils

• 1 cup oats

• 2 cups veggies

• 1 cup berries

• 1 baked potato + a big salad

(Your gut bacteria will write you a thank-you note.) [7][8]

✅ 2) Swap ONE ultra-processed habit

Examples:

• soda → sparkling water + citrus

• packaged snack → fruit + nuts

• frozen meal → simple bean chili batch

• sugary breakfast → oats + fruit

You don’t need a new personality. Just one better default. [3][4]

✅ 3) Choose “mostly plants” as your baseline

Not perfection. Not pressure. Just a default direction that matches the evidence. [1]

✅ 4) Get curious about alcohol and processed meat

This is not a shame statement. It’s an evidence statement. If you want the strongest cancer-prevention moves, these are the two to look at first. [1][5][6]

Takeaways (save this)

• Inflammation is your alarm system, chronic inflammation matters. [2]

• Cancer prevention is mostly about patterns, not magic foods. [1]

• UPFs show consistent links to higher risk across research summaries.[3][4]

• Processed meat has strong evidence for colorectal cancer risk. [5][6]

• Fiber + plant-forward eating is one of the most reliable protective patterns. [1][7][8]

Type 2 Diabetes Isn’t Just About Sugar —It’s About Fat Inside the Cells

There is so much misinformation out there regarding Type 2 diabetes and what someone with it can and cannot eat.  And what causes it in the first place. I receive lots of questions about this in my classes and with my clients.  So for today’s blog, let’s start with a truth bomb that surprises almost everyone:

👉 Type 2 diabetes is not just about sugar.👉 It’s largely about fat inside your muscle and liver cells.

What???  Yes, that’s right. Even though sugar shows up in blood tests it’s not the root cause.

If sugar were the real villain, people who eat fruit would be in big trouble… and they’re not.

So, what’s actually going on?

Let’s break it down, simply, clearly, and without fear.   Keep an open mind.

The short version (before we dive in)

Think of your cells like little rooms with doors.

• Insulin is the key that opens the door

• Glucose (sugar) is the fuel trying to get inside

When there’s too much fat inside the cell, the door gets jammed.

The sugar can’t get in.  So, it stays in the blood, and as a result your blood sugar rises.

This is insulin resistance. This means that the pancreas keeps getting messages that there is sugar in your bloodstream and to make more insulin to get it out. It’s a vicious exhausting cycle with no end in site. As long as the fat in your cells is there, nothing is getting in. Sugar stays in circulation and wreaks havoc on your organs and body. Your pancreas becomes exhausted.

Where fat inside the cells comes from

This is the part that’s rarely explained.  Excess fat inside muscle and liver cells doesn’t come only from body weight. It comes from fat metabolism being overloaded.

That can happen when:

·        Diets are high in saturated fat

·        Fat builds up inside muscle and liver tissue

·        Mitochondria (your cell’s power plants) get backed up

Researchers have shown that intramyocellular lipid (fat inside muscle cells) strongly predicts insulin resistance, even in people who aren’t “overweight” (Shulman, 2000; Shulman, 2014).

So, this isn’t about willpower.  It’s about cell biology.

Why sugar gets blamed (but isn’t the whole story)

High blood sugar is what we see on lab tests.  But high blood sugar is often the result, not the cause.

Studies show that when fat accumulates in liver and muscle cells:

• Insulin signaling is disrupted

• Glucose transport into the cell is blocked

• Blood sugar rises

When that fat is reduced, insulin sensitivity improves rapidly, sometimes within days (Taylor, 2013).  That’s huge.

This explains something confusing…

Why do some people:

• Eat sugar but don’t get diabetes?

• Lose blood sugar control even when “cutting carbs”?

• Improve blood sugar quickly on low-fat, whole-food diets?

Because fat inside the cells, not sugar alone, is the main traffic jam. When we stop consuming high fat foods and lose weight our numbers will begin to move to normal levels.

What the research shows (in simple terms)

• Intracellular fat interferes with insulin signaling in muscle and liver cells (Shulman, 2000).

• Reducing fat in the liver and pancreas can restore insulin sensitivity and beta-cell function (Taylor, 2013).

• Whole-food, plant-based, low-fat dietary patterns have been shown to improve insulin sensitivity and glycemic control (Barnard et al., 2006; Kahleova et al., 2011).

This doesn’t mean all fat is “bad.”  It does mean, however, that it’s where fat goes that matters.

What actually helps (and it’s not extreme)

Here’s the good news: this is modifiable.  It is in our control and can be done under the guidance of a medical professional and limited and/or no drugs.

🌿 Focus on whole, fiber-rich foods

Fiber helps to Improve insulin sensitivity, reduce fat accumulation in cells, and slow glucose absorption.  Think beans, lentils, vegetables, fruit, whole grains.

🌿 Reduce saturated fat (gently, not obsessively)

Saturated fat is more likely to contribute to fat buildup inside cells. Aim for plant-based fats found naturally and not in ultra-processed foods.  This doesn’t require perfection, just pattern shifts.

🌿 Move your body (even a little)

Muscle movement helps:

• Burn stored fat inside muscle cells

• Open glucose “doors” without insulin

• Walking after meals counts. A lot.

🌿 Eat regularly

Skipping meals can increase fat delivery to the liver and worsen insulin resistance.  Consistency signals safety to the body.

Why stress and sleep matter here too

Stress hormones increase fat delivery to the liver.  Poor sleep worsens insulin resistance. This is why diabetes care isn’t just about food, it’s about the whole system.  Which brings us to mood, gut health, and serotonin…

Want a gentle place to start?

While I don’t have Type 2 diabetes, I do have blood sugar sensitivity.  That’s exactly why I created this 7-Day Serotonin Reset Plan.  And I wanted to share it with as many people as possible.  That is also why I am making it available to you FREE!  My 7-Day Serotonin Reset Plan is designed to:

• Support blood sugar stability

Big takeaways (save this part)

✔ Type 2 diabetes isn’t just about sugar

✔ Fat inside muscle and liver cells blocks insulin

✔ This is biology — not a discipline issue

✔ Small food and movement changes matter

✔ Support works better than restriction
