I never would finish one serving of cereal but of course, who eats zero cereal, don’t buy cereal…
So it’s elsewhere too, not surprising. The only thing I saw with “KETO” on it was oatmeal. Very normal oatmeal with fruits and stuff, just tiny (and expensive as all oatmeal in a package*)… Getting less than 20g carbs from a teeny-tiny high-carb stuff isn’t so very much keto to me… It CAN be eaten on keto, sure. It doesn’t worth it for anyone I suppose but it is possible. Everything is keto that way.
*I just don’t get this laziness(? if it can be called that). There are tons of stuff that is far from ready to eat, you still need to make it - and it’s about as much work if you just use cheap ingredients. Pancake powder, muffin powder, there is all kind of stuff that makes zero sense to me. They usually even need the person who buys them to add egg and milk!
