Only about 20-25% of insulin release comes directly from carbs. Here's the "other 77%" - the foods, habits, and lifestyle factors that also drive insulin.

Wholist Answer: 23% of Insulin Is Released by Glucose Intake (PDF)
I was surprised by this. I know you'll get into the other 77% but what else should we be avoiding besides flour and sugar?
Love this question - it shows you're thinking beyond calories and starting to understand metabolic signaling Here's how I'd answer this in Wholist voice:
Wholist Answer: "The Other 77%" of Insulin Stimuli
You're totally right - only about 20-25% of insulin release comes directly from glucose intake (aka carbs like sugar and flour). The rest comes from everything else that influences your pancreas, liver, and fat cells to communicate about "energy availability." Here's what to know
Food Triggers Beyond Sugar and Flour
- Refined starches + ultra-processed foods
- Even if not "sweet," these break down fast into glucose (think chips, crackers, cereals, granola bars, pretzels, white rice). Fast spikes = insulin surges.
- Frequent eating / grazing
- Every snack or sip of caloric drink triggers insulin-even "healthy" smoothies or oat milk lattes. Your cells never get a break to burn fat if insulin is always whispering "store."
- Certain amino acids (protein spikes)
- Protein is crucial, but very large portions (esp. without fiber or fat) can transiently raise insulin. Balanced meals keep it steady.
- Fats combined with refined carbs
- This "hyper-palatable" combo (pizza, fries, pastries) is insulin's worst nightmare. Fat itself isn't insulinogenic, but when paired with refined carbs, it supercharges the storage signal.
Non-Food Insulin Stimuli
- Chronic stress → cortisol → insulin resistance
- Your body thinks it's in survival mode and holds onto energy.
- Solution: daily nervous-system downshifts (breathing, walking, music, laughter).
- Poor sleep
- Just one night of <6 hours can spike insulin resistance by 20-30%. Prioritize recovery like you would a workout.
- Sedentary behavior
- Muscle tissue is your biggest insulin sink. Move often-mini strength or stretch breaks make a real difference.
- Environmental toxins / inflammation
- Processed seed oils, alcohol, and inflammation from gut imbalance or chronic illness can all reduce insulin sensitivity.
Wholist Takeaway
So yes-limit flour and sugar, but also:
- Ditch ultra-processed snacks
- Space meals 3-4 hours apart
- Build muscle
- Sleep like it's medicine
- Manage stress intentionally Because the real insulin magic isn't just what you avoid-it's how you live between meals.
