If that ugly beast spent honest-to-goodness meaningful miles in the saddle, then it wouldn't be a lard-ass.  i will have to disagree here. you can exercise a lot and remain fat - know it, because i've been there. i've been cycling to and from work for the last, oh, 8 years now. i moved further and further from the office, so my commute was 5, 9, then 23 km one way. the amount of biking i did (and do) is certainly above average, but i remained fat, borderline obese (BMI 28-30) all this time - until i changed my diet, which was about 18 months ago. that and only that brought my weight down into normal range. i'm stating the obvious here, but exercising won't do shit unless you change your eating habits.
