More Protein, Less Regular? Here's Why.

High-protein diets often crowd out fiber-rich foods — less volume, less bulk, slower digestion. The more you protein-max, the wider that fiber gap usually gets. ForBelly closes it without changing how you
eat.

The Fiber Gap in Every High-Protein Diet

When protein takes up more of your plate, fiber-rich foods like whole grains, beans, and produce usually take up less.
Less fiber means less bulk moving through your gut — which is exactly why constipation is one of the most common complaints among people ramping up protein intake. It's not a flaw in your diet, it's just math: more protein, less fiber, slower digestion.

How to Take It

Best Time to Take ForBelly on a High Protein Diet

Take once daily to start, ideally before a meal — many people find mixing it right into their protein shake is the easiest way to build the habit. Follow the ramp-up schedule (1 tsp daily, building to 2 tsp
twice daily) so your body adjusts smoothly



What Customers Are Saying

Frequently asked questions

Will fiber interfere with my protein absorption?

No — fiber and protein are absorbed through different processes. Taking ForBelly alongside your protein doesn't reduce how much protein your body uses.

How much fiber do I actually need if I'm eating a lot of protein?

Most adults fall short of the recommended 25–38 grams of fiber per day, and that gap tends to grow the more protein-focused a diet gets. ForBelly adds 5g of fiber per serving to help close it.

Can I mix this into my protein shake?

Yes — it mixes smoothly into shakes, coffee, or water. Just follow the mixing method: a little liquid first, stir briskly, then add the rest.
