Not sure if I can simplify the fat counting but here's what I do. Say an item is 5 grams of fat. Each gram is 9 calories, 5x9=45calories. Just figure your meal calories and keep the fat calories below 25%.
I wanted to mention that when I first started this spaghetti sauce did me in. But now after being stable I can eat the plain sauce without any problems. It took a few months for me to be able to eat some foods. Give it some time, you'll see improvement. Think of your bowels being assaulted over a long period and it's going to take some time to calm things down. The CD's took some time for me and now I'm doing them a second time. Some people had to do them more than one go round for them to work. Hang in and I give you lots of credit for not just jumping ship when your frustrated. This board is so helpful I love it. But be sure to soak up all the valuable information Heather gives in her books and the main site here. Cooking for my husband isn't such a chore now, I just cook his red meat and my chicken,fish or whatever. I eat most of the same veggies and of course my potatoes/rice/grits or something similar. Lately sweet potatoes are on my plate a lot. You don't have to be hungry on this diet. Explore all the recipes but at first keep it simple so you can focus on stabilizing.
