For what its worth, this is my opinion . . .
I think you shoud keep an eye on all of it. I've been counting calories for over a year now and I find that the only way to fill up well enough on my lower-calorie level is to eat low-fat and lower sugar levels. Basically, if you eat a small enough number of calories, you'll lose weight but in order to feel fullfilled (and more likely to stick with it as a result), I'd suggest limiting the fat and sugar too. A good tool is
www.fitday.com where you can input your daily foods and it will let you know how you're doing
From what I've heard one should eat no more than 30% of their calories from fat and no less than 10% from fat (one needs SOME fat in their diet!). I try to aim for between 20% and 25% fat myself.. Its tough sometimes but I actually feel much better when I'm not eating that extra fat!
I aim for around 1400-1500 calories a day so that should work out to be like between 30 and 40 grams of fat a day.. give or take a couple.
Hope that helps.. I've got my 2 cents all over the place tonight.. so just tell me to shut up if I'm babbling
