This screen allows you to track your body weight.
If you did enter weigh-in for the current day, it will be displayed, and you can update it. If you did not enter your weigh-in for the day, the comment below will display your previous weigh-in.
Also, if you lost some weight, this screen indicates how much you've lost so far.
If you are concerned that someone else may see your food diary and your weight, you can turn on PIN code protection on the Settings screen.
Finally, your BMI is calculated and displayed on this screen at the bottom.
