Has anyone tried cutting out flour-based foods for a diet?

Flour-based foods, which are refined carbohydrates themselves, are not only bad for your health

I heard it's bad for the skin, so I'm thinking of quitting this time.

I love flour-based foods so much that I'm usually called a bread lover and a noodle lover.

It wasn't easy to quit all at once.

So, if anyone has successfully quit flour-based foods...

It would be a great help if you could share that know-how.
