The 1-2-3 Fiber Strategy: An Easy Way to Eat More Fiber Every Day
Most nutrition conversations today are focused on protein—and for good reason. Protein is essential for maintaining muscle, supporting metabolism, and helping us stay strong as we age.
But there's another nutrient that deserves just as much attention.
Fiber.
Fiber plays a powerful role in supporting gut health, lowering cholesterol, improving blood sugar regulation, and building long-term resilience. Yet most people simply aren't getting enough of it.
If you've ever wondered how to eat more fiber without counting grams or following a complicated meal plan, here's a simple approach that works.
The 1-2-3 Fiber Strategy
Instead of tracking fiber, think about building it naturally throughout the day:
Breakfast: 1 serving of fruit or vegetables
Lunch: 2 servings of fruit or vegetables
Dinner: 3 servings of fruit or vegetables
That's it.
Six opportunities throughout the day to gradually build more plants—and more fiber—into your routine without turning food into a math equation.
Simple. Sustainable. Easy to remember.
Meet the "Villagers" Living Inside Your Gut
I often like to talk about the “villagers” living inside the gut — the trillions of microbes that rely on fiber to thrive.
Every time you eat fiber-rich foods, you're feeding these microscopic helpers that influence everything from digestion and immunity to inflammation, metabolism, and even brain health.
When we consistently nourish them, they work incredibly hard on our behalf.
So to build upon that, I want to share one of the simplest strategies I know for getting more fiber into your day - without tracking a single gram.
Because while nutrition conversations right now are heavily focused on protein (which absolutely matters), fiber may be one of the most under appreciated nutrients for supporting gut health, cholesterol, blood sugar regulation, and long-term resilience.
And most people simply aren’t getting enough of it.
My Fiber Experiment
A while back, I intentionally increased my vegetable intake for several weeks.
I was trying to roughly hit the following benchmarks on a daily basis, although not always successful - but close enough:
2 cups cruciferous vegetables
2 cups dark leafy greens
2 - 3 cups additional vegetables
½ beet
¼ cup pumpkin seeds
¼ cup sunflower seeds
Yes—that’s a lot of fiber, adding up to roughly 30 grams per day.
The result surprised me.
Just three weeks later, my bloodwork showed the best cholesterol numbers I’d seen in years.
That certainly got my attention.
Fiber Does More Than Feed Your Gut
One of the most overlooked benefits of fiber is its ability to improve cholesterol levels.
The key player here is soluble fiber — the type found in foods like:
oats
barley
beans
lentils
apples
psyllium husk
When soluble fiber dissolves in the gut, it forms a gel-like substance that binds to bile acids.
Because bile acids are made from cholesterol, your body has to pull more cholesterol from the bloodstream to replace what gets eliminated.
But when fiber traps them, they get excreted instead — and the liver has to pull more cholesterol from the bloodstream to make new bile acids.
The result?
Over time, many people experience a meaningful reduction in LDL cholesterol.
Research consistently shows that increasing soluble fiber intake can meaningfully improve cholesterol markers, blood sugar regulation, and metabolic health — without extremes, detoxes, or complicated nutrition rules.
That’s why foods like oats, beans, lentils, and apples are so remarkable.
They’re doing two important jobs at once:
Feeding your microbiome
Supporting healthy cholesterol
Two jobs. One meal.
Why Most People Fall Short
Most experts recommend consuming at least 25–30 grams of fiber each day.
Unfortunately, the average American eats far less than that, and fewer than 10% of adults are thought to meet the recommended intake.
Part of the challenge is that fiber feels abstract.
People hear "30 grams" and immediately think:
"That sounds difficult."
Or:
"How would I even get there?"
Keep It Simple
I'm not a fan of overly complicated nutrition systems.
What tends to work much better is having a simple framework that gradually becomes second nature.
That's exactly why I teach the 1-2-3 Fiber Strategy:
Rather than counting grams, simply ask yourself one small question whenever you're building a meal:
Where is the fiber coming from?
Sometimes that means:
Adding beans or lentils to soups and salads
Mixing berries or chia seeds into yogurt
Choosing whole grains more often
Building meals around vegetables instead of treating them as an afterthought
These small decisions gradually shift your overall pattern of eating.
And those shifts support the microbes, metabolic pathways, and countless cellular processes quietly working to keep you healthy.
One important note: if your current fiber intake is low, don't try to jump to 30 grams overnight. Increasing fiber too quickly can cause digestive discomfort. Instead, build gradually, giving your body—and your gut microbes—time to adapt.

To make this even easier, I created a free 1-2-3 Fiber Guide that shows how fiber can naturally build across your day without tracking every gram.
It highlights many of the highest-fiber foods so you can quickly recognize the "heavy hitters" and confidently include more of them in your meals.
Healthy Aging Is Built One Habit at a Time
Health often changes not through one dramatic overhaul, but through small repeated actions that quietly improve the environment inside the body.
More plants.
More fiber.
More support for the systems working hard on your behalf every single day.
And your villagers will appreciate it.
