How do i use calorie count to keep track of calories???

I know that you have to go o the add food thing.

But they dont have EVERYTHING 

  like.......

• Home cooking
• School lunch
• certain brands

They just have major food  places like pizza hut but u cant put like exactly what you had on the pizz or the same thing for subway.

So i there another way to keep track of calories or what?

For home cooking, just go to Foods and then "New Recipe". It will allow you to enter a recipe, and then it will give you the nutritional information for it. I use it all the time, and now I know how absolutely horrible my birthday cake is for me(: haha.
For school lunch, I normally just enter it as a different brand that I'm familiar with and guess that its close enough. You could try to start bringing your own lunches to school- I've been doing this lately, and now I know exactly how many calories I consume and i can pack myself exactly what i want!

If the brand you're looking for isn't on CC, try doing a google search for the nutritional information of it. There are other websites like CC that have different foods.
