HaHaHa!!! yeah, guess it's the water...When I started on a higher protein diet things became "different", and it's been driving me crazy.Well, without being too nosy is everything uh, okay in the elimination department? Because with the foods you've listed (I would substitute the quick oats for something that's slower cooking, just because they'll stick with you longer) if you're actually having elimination problems, then it's probably insufficient water.
Also, if you're having the banana because breakfast isn't holding you until your next meal then consider trading that for a scoop of a protein powder in your oatmeal instead.
If you're just worried in terms of getting a certain gram of fiber but everything is alright, then that's a whole other ball of wax. Personally, I worry more about my protein/carb/fat/calorie numbers, if I started worrying about fiber, salt, calcium, etc. I'd lose what little mind I have left
You know, i was having the banana because i was maybe misguidedly thinking that the fruit made the meal more balanced??? I don't know...also I like bananas.
My macros are holding steady at P-40%, C-20-30%, and Fat 20-30%. Sometimes my Protein goes up to 50%...
