I get more fiber through my protein drinks than most average Americans do through their lousy, greasy diet.
I am not a smoothie evangelist, but I have gotten healthier with two of those a day, plus fruit, than I have been for years.
You just need to be careful that you limit the sweet sugars in the drinks. Some of them are just horrible.
I believe the fiber that has been emulsified is not as good as the roughage you get from eating fiber rich foods. Now that being said, you say you’re also eating fruit, and that is a fiber rich food.
You also state that you eat a third meal per day. You’re probably getting fiber in that too.
I don’t see a problem with what you’re doing. You’re probably keeping your weight in check and getting a broad variety of vitamins and minerals to boot.
I’m not a dietitian so folks reading this should take it with a grain of salt..., or something more healthy. :^)
