Fifth installment of "Harry Potter Diet" series. We got a new scale. It's pretty fancy -- it's a Garmin and it supposedly measures all sorts of stuff beyond weight, such as percentage of body fat, water weight, skeletal muscle mass, BMI, cholesterol level, blood pressure, sense of humor, favorite Spice Girl, how many days it's been since you stubbed your toe, high score on Ms. Pac-Man ... I haven't figured out all the features yet. I have figured out one thing about it, though: I hate it.
