Back in my calories only days, I had pretty much given up peanut butter completely because it just wasn't delicious enough for how many calories it had. One day shopping, I notice reduced fat peanut butter. I pulled the reduced fat off the shelf and also the full fat. Yep, less fat. Calories - almost identical.
So, whether they're getting it from fat or added cornstarch, or sugar, eating low fat does absolutely nothing if you don't take the time to see if the product is really an improvement.
Alton Brown once showed that if you fry at the correct temp for both the oil and the food you're preparing, you don't pick up that much oil in your food. I forget what he was frying (and of course he was using "healthy" vegetable oil), but it was a lot. He measured the oil left in the pan, and there wasn't that much gone. However, he's a food person, and most of us don't want to look up foods and temps for each meal. Also, anything one doesn't prepare with one's own hands is most likely going to have the magic salt+fat+sugar thing so you eat more of it.
I think there's an old thread here somewhere that showed that Fage yogurt is one of the few fat free or low fat prepared foods that actually doesn't add carbs when they take out the fat. So, out of the gazillion foods out there that have been re-recipe'd (not a real word) to be able to put 0% fat on the label, there's at least one that did it right. I've never seen another, but there must be some out there.
Anyway, how could Primal ever get boring? You have to watch everything. Grass fed might not be grass finished. Things with "Healthy" in the name almost never are. If you don't live in a trendy area, you have to search online for some foods. The most simple prepared foods (tomato sauces, etc.) are laden with crap. Heck, it takes time reading all those labels!
