Calories Budget Indicator
The indicator for the Calories Budget seems confusing to me given the title "Calories Remaining" and the use of positive and negative numbers. From one perspective, it does make sense when there are calorie remaining, however if you're over it doesn't seem as intuitive. There's an inherent conflict between the wording the representation of the number as a negative.
I would recommend the following
1. Use three distinct colors to visually call out if the person is under, over or on budget.
2. Change the text dynamically to "Over Budget", "Under Budget" and "On Budget"
3. Get ride of the minus sign
The popup may need to be changed accordingly. However, I don't have any specific thoughts other than to make it consistent with the recommenations above
