not counting fruit or veg

The OP said she wants to *ease* back into calorie counting after having an arguably easier system with WW. (Note: I actually think MFP is easier than WW, but I didn't when I was a new "convert.")

Obviously we all know ALL calories count, and that excess calories make you gain weight whether it's from funnel cakes (mmmm, funnel cake...) or broccoli. That's not what she's asking. She's come up with a temporary system she wants to try until she gets in the swing of things. If this temporary system helps her get started, I see no harm in it.

Now ... to the OP. As others have mentioned, WW takes into account "free" foods by lowering your daily allotment of points. I think you could do something similar with calories. Figure out roughly how many calories in fruits/veggies you eat on a typical day, and subtract that from the calorie recommendation MFP gives you. So, let's say you estimate you'll eat 450 calories in fruits/veggies and MFP tells you to eat 1450 calories a day. Just subtract 450 and eat 1000 calories, not counting fruits and veggies.

I do agree that you should eventually begin to count them, because it's too easy over time to let the calories creep in. But, as I said, if this is what you need to do to get into a healthy mindset for MFP, then I say go for it - just be cautious to actually estimate your true intake and don't take advantage of it. Otherwise, you will only be cheating yourself in the long run!
