If you get a nice, relatively healthy Jamba Juice for lunch, and put in a “Burner Boost” which is touted for “increasing metabolism, burning fat, and suppressing hunger while providing energy and great nutrition,” you will, on the way back down from the incredible vision-blurring caffeine high, get such incredible low-blood-sugar munchies that you will be forced to buy a bag of M&Ms from the vending machine at the office, thus blowing any caloric advantage to getting a nice, relatively healthy Jamba Juice.
You have been warned.
