What works is going on a liquid diet for a while.
Examples: Raw protein shakes(eggs as the base,then add whatever else like milk/water)
Or,if you're cool with some cooked food: Chicken soup.
The point is to stay away from solid food until the area heals.
Increasing your fats was a good idea.
So,after the area heals,just adjust the ratio until you find what works for you.
If that doesn't work,you may need to take a HCL supplement to increase your stomach acid.
Or,if you're not into supplements,perhaps 100% beef is not the right diet for you.Good luck
