You eat a decent breakfast, and by mid-morning you’re starving again. You hit a wall around 3pm and reach for coffee or something sweet just to make it to dinner. You feel wired at night but wrecked in the morning, and the weight around your middle won’t budge no matter how “good” you eat.
If any of that sounds like your day, blood sugar crashes may be running the show. A functional medicine approach looks at this very differently than a standard fifteen minute checkup does.
Here at Mitchell Holistic Health in Onalaska, we see this pattern constantly. People come in frustrated because their labs came back “normal,” yet they still feel off. The honest truth is that blood sugar trouble usually starts years before it ever shows up on a basic glucose test.
The blood sugar roller coaster, explained
Every time you eat, your blood sugar rises. Your pancreas answers by releasing insulin, the hormone whose job is to move that sugar out of your bloodstream and into your cells for energy. In a body that’s humming along, this happens quietly and you never feel it.
But when meals are heavy on quick carbs and light on protein, fat, and fiber, blood sugar spikes high and then crashes hard. That crash is the shaky, hangry, need-a-snack-right-now feeling. Over time, if your cells are constantly flooded with insulin, they start to tune it out. That’s insulin resistance, and it tends to show up as stubborn belly weight, relentless cravings, afternoon fatigue, and that foggy, half-a-step-behind feeling.
Why your “normal” labs can miss it
A standard panel usually checks fasting glucose, and maybe hemoglobin A1c if you’re lucky. The problem is that both of those tend to lag. Your body can work very hard to keep glucose looking fine for years while insulin quietly climbs in the background.
Through a functional medicine lens, we look deeper. We like to see fasting insulin alongside glucose, and we often calculate HOMA-IR, a simple ratio that gives us an early read on insulin resistance long before a glucose number ever budges. For some clients, a continuous glucose monitor changes everything, because watching your real reactions to real meals tells us far more than a single fasting snapshot ever could. We’re also less interested in “inside the lab range” and more interested in what’s actually optimal for you.
Signs your blood sugar deserves a closer look
Energy that crashes a couple hours after eating, or a hard slump around 3pm
Getting genuinely hangry, shaky, or irritable when a meal runs late
Cravings for sugar or carbs that feel bigger than willpower
Waking around 2 or 3am and struggling to fall back asleep
Weight gathering around the middle even when your eating hasn’t changed
Mood swings and that frustrating afternoon brain fog
The Mitchell Holistic Health difference
We’re not going to hand you a rigid diet sheet and send you on your way. We test first so we actually understand what your body is doing, then we build a plan around your real life, your schedule, and the food you genuinely enjoy. Root cause, not willpower.
The functional medicine approach: steady the foundation
Balancing blood sugar is rarely about eating less or trying harder. It’s about giving your body steadier inputs so it stops swinging between spike and crash. Once we know your numbers, the foundation we focus on usually includes a few gentle shifts.
Lead your day with protein. A breakfast built around protein and healthy fat keeps the morning crash from ever starting.
Stop eating carbs naked. Pairing them with protein, fat, or fiber softens the spike. Same food, calmer ride.
Move after meals. Even a ten minute walk helps your muscles soak up blood sugar. Bonus points for our beautiful Coulee Region trails.
Protect your sleep. One short night nudges cravings and blood sugar the very next day.
Soften the stress load. Stress hormones raise blood sugar all on their own, no food required.
For some people, targeted nutrients and the right kind of strength training round things out. That part we tailor to you, because the goal is steady energy you can actually feel, not another plan you white-knuckle for two weeks and abandon.
You don’t have to ride this out
If you’ve been told everything looks fine but you still feel exhausted, foggy, and frustrated, you’re not imagining it and you’re not lazy. Your body is asking for a different kind of support. The blood sugar roller coaster is one of the most responsive patterns we work with, and steadying it tends to lift energy, mood, sleep, and weight all at once.

Frequently asked questions
Can I have insulin resistance if my blood sugar is normal?
Yes, and this is one of the most common things we see. Insulin can run high for years while glucose still looks fine, which is exactly why we like to test fasting insulin and HOMA-IR rather than relying on a glucose number alone.
Do I have to go keto or cut out all carbs?
No. Most people do beautifully without anything that extreme. The goal is balance and the right pairings, not restriction. We build the plan around food you actually like to eat.
What testing do you use for blood sugar?
Depending on your picture, that can include fasting glucose, fasting insulin, HOMA-IR, hemoglobin A1c, and sometimes a continuous glucose monitor so we can see how your body responds to your real meals.
