What do the lock icons mean on the Goal screen?

The Goal screen consists of your Goal (where do you want to go?) and your Plan (how do you get there from here?)

Once you select a Goal weight, the Plan section appears. It contains a Goal Date, Weight Plan, and Energy Plan. For example, let's say I weigh 190 lbs on September 30, 2010 and I want to lose ten pounds. Once I set a goal of 180 lbs, the screen will look like this:

Goal180 lb
DateFebruary 18, 2011
Energy-250 cal/day
Weight-0.5 lbs/week

In plain English, if I want to weigh 180 lbs by February 18, 2011, then I must burn 250 calories more than I eat per day (which is equivalent to losing half a pound of fat per week).

As time goes by and your weight changes, FatWatch will update these numbers. If you proceed exactly according to plan, all the numbers will stay the same. But if your weight changes more quickly or slowly than you planned, you have a decision to make: Should you adjust the Energy and Weight in order to meet your deadline? Or do you want to keep the plan the same, and adjust the Date accordingly?

A lock icon next to a value indicates that FatWatch will keep that value fixed. If the lock is next to the Date, then the energy and weight plan will adjust to tell you how to get there on time. If the lock is next to the Energy and Weight, then the date will adjust to tell you when you can expect to get there.

FatWatch will lock whichever value you changed last. For example, if you want to move the lock to the date, tap the date field and then tap save.

Once you have set a goal, the Trends screen will display additional analysis, comparing your actual rate of progress to your plan, and if you're off track, advising you how to get back on.
