I googled the difference between FIBER and FIBRE and it's the same like TIRE/TYRE. Just a spelling variation.
My fibre comes from wholegrain bread, fruit (1 banana has 3.5g) Quorn (veggie meat) has 6g in 100g and from homemade sauce of onions and tomatoes. It all adds up. Also, consider if you have some custom foods, maybe you didn't enter fibre when you were creating them.

It is foolish to keep doing the same things and expect different results.
