Diet Hero App
If you don't want to count calories, there is an interesting alternative that turns this activity from something you do after you eat, to a meal planning style approach that is proactive.
You tell Diet Hero what foods you like and what foods you have, and the app will tell you how much to eat and what to eat. If you only have a few things handy at home the app can adjust to that so you don't need to scramble to find something that may not be as healthy.
If something doesn't sound good, you can choose to swap it out and the app will intelligently swap a protein for a protein and a carb for a carb.
With the info you share including height, weight, gender, the amount of weight you want to lose and how fast the app will tell you what to eat and how much to eat so that you can meet your goals.
Diet Hero is free until January 1st, and then it is $1.99 and it is only available on iPhone at this time.
