Fibermaxxing Isn't the Point: Closing the Fiber Gap Is

There's a new suffix taking over the wellness internet: "maxxing." Proteinmaxxing. Sleepmaxxing. Looksmaxxing. Fibermaxxing. Apparently, if you're not chasing the absolute upper limit of every single nutrient, habit or personal best, you're falling behind.

And depending on what is being touted as the optimal or upper limit, the chase can be an exercise in misery. 

I see female patients every day who are gagging on chicken breast and protein shakes as they try to consume 1 gram of protein per pound of weight each day.  This is a ridiculous standard that is not grounded in reality for anyone but the most extreme body builders.  Half of that amount is plenty for the average person participating in moderate physical activity.

Sleep?  OK – we could probably all be well served by getting more restorative sleep. 

Looks?  We are all beautiful in our own way. There is no need to smash our jaw bones to simply achieve an idealized facial appearance (aligning dentition is a different consideration).

But fiber?  I’m not sure we even understand what the upper limit should be.  The human ancestral diet was largely plant based and estimated to deliver about 100 grams per day. That’s 3 to 4 TIMES higher than the recommended daily allowance for Americans.

And even with the RDA being just a fraction of what humans were genetically engineered for, most of us consume HALF of that fraction.  When it comes to fiber, we are VERY far from “maxxing”. 

Meanwhile “maxxing” implies there's a ceiling most of us are already near. With fiber, the real story is a gap, not a ceiling, and most of us haven't come close to even closing the gap. So before we talk about “maxxing” anything, let's talk about starting.

How Much Fiber Do Most of Us Actually Need?

The average adult in this country gets around 15 to 16 grams of fiber a day. The recommended range is 25 to 38 grams, depending on your age and gender. That gap isn't a rounding error. It's the difference between what your gut needs - at minimum - to function well and what it's actually getting. So we are worrying about maxxing instead of solving a problem most people haven't even identified in their own diet yet.

Here's what fiber is actually doing for you at the levels most people are missing. It feeds the bacteria in your gut that produce compounds linked to lower inflammation and increase satiety. It slows how fast sugar hits your bloodstream after a meal. It keeps things moving through your digestive system the way they're supposed to. None of that requires you to chase some optimized upper-limit number. It requires closing the gap you already have.

Especially since closing the gap is where you get the biggest bang for your buck! Just like with exercise where the greatest health benefit is realized when you go from doing nothing to doing something, the greatest health benefit for fiber intake is when you go from being deficient to just meeting the minimum.  Yes, more is better – but the incremental health benefits are less steep.

What's the Easiest Way to Actually Close the Gap?

If you're currently getting somewhere around 16 grams a day, the goal isn't to jump to 40 (or 100) next week. It's to add one source of fiber you don't already have. A pear instead of pretzels. Oats instead of processed cereal made with oats. One swap, repeated daily, closes more of that gap than any maxxing protocol I've seen recommended online - mostly because you'll actually keep doing it.  

That "one swap" idea is the same philosophy behind Step One Foods, though fiber is only one piece of why it works. I built it around four ingredients with real evidence behind them — fiber, plant sterols, antioxidants, and unsaturated fats — all aimed at the same goal: helping lower LDL cholesterol without asking you to overhaul how you eat. Fiber is doing real work in that formula. It's just not the only reason to make the swap.

The people getting real benefit from fiber right now aren't the ones chasing 40 plus grams a day. They're the ones who finally started, even if starting just means one swap, repeated most days.  

As I always say to my patients, it’s not about being perfect. It’s about being better.
