Well to answer your first question again, my diet doesn't have that much fat in it. I'm getting 72g of fat per day which is only 30% of the calories.
As for your 28g of fat per meal, it's because I advocate fat in 4 out of the 6 meals. For simplicity the spreadsheet divides this evenly into 4 meals, however it is just a guideline to give you an idea of where to start. I get 72g of fat per day so broken into 4 meals that's 18g a meal. However I only usually like getting about 12g for breakfast which means I have to get more fat in my last 3 meals which is perfectly fine.
If you think that much fat will hinder your workouts then don't get 28g in your pre-workout meal. Get what you want but make up the difference in your other meals. When people follow a true CKD they are getting a lot more fat than I'm suggesting and are able to get through workouts with no problems. Fat is just an energy source like carbs, doesn't need to be treated any differently.
