Does anyone know of any long-term drawbacks to losing weight more rapidly than 2 lbs. a week - provided one is doing so in a healthy manner? I'm eating my recommended daily intake of calories (around 1300), and, rather than losing one pound per week, I have lost 8 pounds in one week.
Has anyone had a similar experience? I'm thrilled with the results, obviously, but concerned that perhaps I'm not getting enough calories. The BMR isn't an exact science -- for example, how do I know if i'm moderately active or very active? I live in a city and don't own a car, so I am constantly walking, running up stairs (esclators never turned on in Toronto the Poor), etc. I try to log it all, but perhaps I am underestimating my level of activity?
