You are right, Irish, nuts are high in fats but it's also HEALTHY fats. My 12 raw almonds equals about 7 grams of fat, which I need with my breakfast since everything else I eat is very low fat. They are also high in Protein (3 grams), which is another nutrient that many people don't get enough of. So, eating nuts in moderation is something you can do when you are having trouble meeting your fat grams. :)
Definitely do not "save up" fat grams. You really want to space them out through the day.
There are other nutrition/food journals on the web. Do a search and you may find one that is easier for you to use. I've been using FitDay for the last year and have found it very helpful.
Hope this helps.
