Question about My Fitness Pal

A lot of you like it a lot, but what exactly is it???
Is it a calorie counting diet????

I went on the website but couldn't find out what the exact program was. Can someone explain how it works. Just curious since so many people love it.

Question about My Fitness Pal

I have the app on my iPad. It's a food and journal. You plug in your weight, how much you'd like to lose, and it calculates for you how much you should be eating calorie-wise, but also tells you how much of that should be carbs, protein, fat etc. It even shows how much sugars, vitamins, iron etc you are getting and if you are over or under. You type in what you ate and pretty much any food you eat is listed in their database so it's rare that you even need to plug in the nutrition info on your own. It also tells you how many calories you need to burn. The thing is great!
