Cheese was the thing killing me. I'd make a chicken wrap with cheese and spinach, and half the calories were the slice of cheese. Crazy. I've been using MyFitnessPal for about a month. I don't love it, but it integrates with my Garmin fitness watch. For me, to feel sane, it isn't a travesty to deliberately cheat, i.e. knowingly go over my calorie limit occasionally. For me personally, it is terrible to lie to myself about how terrible some food is or how much I ate. The more honest one is with themselves and their calorie tracking, the better. (Though I'm on vacation right now and my log is a mess these last few days. There's no cell service, making it a bit more difficult.) MFP tells me my limit is about 2000 calories/day. Some days this seems hard. I find it's easier for me to burn 200 calories exercising and eat 2200 calories than to do nothing and eat 2000. But again one needs to be honest about the exercise. I've heard it said "it's hard to outrun a donut."
I've been using MFP for about four years now, and LoseIt for about 18 months prior to that. It gives me 1800 calories. Or, about 400 more than my 3-year old is supposed to get. Then it says I burned 1100 calories shredding brush. Whatevs, MFP.
I entered 10 hours of hiking into MFP. It told me over 5000 calories burned. It was a long day, and I'm sure I used a lot of energy, but that's ridiculous. I'm not sure I'd believe anything over 2000. The food calories seem to work well for me, though, and exercise in smaller amounts seems reasonable. I don't think exercise calories scale correctly.
