It's silly, especially to admit on this forum, but I found the Hidrate water bottle that tracks your water consumption actually increased my water intake loads as well.
Also cruciferous green vegetables, potatoes (boiled or baked, not fried).
I don’t eat salads because of my hiatus hernia, and I generally prefer cooked food, but they are also good.
For breakfast I eat grains. Oats (quick cooking mixed with steel-cut). Or sorghum, and even wheat grains also make really nice cooked cereals.
Also can’t forget the other legumes/pulses lie lentils and chickpeas!
Any full grain bread recommendations? When I worked at a super market a brand of “sprouted grain” was popular.
Or take a look at bircher muesli.
You don’t have to use it if you’re getting fiber but if you notice you had a day or series of days where it was low then drink a Metamucil. It’s great.
