Is this ok to eat during week 4?

I'm two weeks post-op and soft cheese was on my list of things I could eat during the soft foods stage. I had one of those Laughing Cow cheese rolls with no issues at all. I would say just nibble on just a little Velveeta and see how you feel. If it doesn't bother your tummy too much, I'd say go for it! As with everything, just make sure you measure your quantities. I love cheese to the moon and back so I can easily picture myself getting carried away.

No way to heavy Plus that is fake with tons of Garbage in it

Technically yes but do you really want to? It's not really a good option. Choose real cheese instead of a processed cheese food byproduct.
