Fiber and bloat

Bloating after adding fiber is normal. Your gut bacteria are adapting (in other words your bacteria was cooked). Give it 2 weeks. Expect crazy good results.

Why it happens

What’s going on

When you suddenly increase fiber, gut bacteria ferment it

Your body needs 1–2 weeks to adapt and “recruit” the right bacteria.

Fiber type matters

If you go with beans, lentils, chickpeas = gonna be rough

If you go with veggies & chia = manageable and easier, check:

Fiber grocery plans (3 starters)

The fix

If stomach feels funny

Day 1 10g, day 2 15g, day 3 20g etc until you reach 40g.

Water is non‑negotiable

Don’t track for fiber, just remember you should drink at least 2L a day regardless.

Chia seed water rules

Chia is 34g fiber per 100g — don’t go all-in on day one (it won’t end well)

Start with 1 tbsp, can build over to 2 tbsp

Timeline expectations

Week 1: gonna be rough with… bloating

Week 2: should reduce significantly

Week 3+: new baseline feels normal

If it’s still bad after 2-3 weeks, you will need to research on FODMAP. I will help you.
