I found the Weight Goal tab very helpful. If you haven't checked it out already, you can put in your starting weight and goal weight. Fitday will calculate the calories you need to consume to reach that goal. It's great once you start losing to see the graph that shows where you should be as far as your weight and if you are on track. Fitday will also show you your current BMI and goal BMI and let you know what a healthy range is for you.
