Other times, people are just wired to do better at moderating food intake or sticking to a workout plan.

Linear regression on the data gives a gradient of about -0.1 grams per day, or -400 grams over the whole period. However, as the standard deviation of the weight is about 700 grams, this is indistinguishable from zero (as I knew already ...
