i have found there's little need for fibre with beef steaks. with milk, a little helps, but a few teaspoons of cacao powder covers it mostly, it has quite a bit of fibre, like 10% by weight.
i should point out that the amounts of fibre needed are not huge. just put a teaspoon of psyllium husk into some water and see how much water it takes on, then multiply that by about 3x to include all the solid matter in your meal that will pass through.
if you have more than equivalent of about 3 teaspoons of psyllium husk per day you will actually have trouble ejecting the extra hard.
