Results (i.e. rapid mileageful attributable visible progress) is the best motivator
Trying Atkins after months of the drudgery of calorie counting.
It is rapid: you see results 2 days in. It is mileage: It is meaningful amount of progress each day (the mileage is high) It is attributable: I can connect it to what I am doing It is visible: Both on the scale and the body
And it is progress!
