No its not easy,that was part of the point,excuse me for not being more concise,it does take LOTS of miles to do that.Takes a long time too,on the otherhand best thing is to ride regularly even if its only an hr or so/day,most ppl can fit that in their schedules.Still like anything else in life,it takes dedication and work,IMHO thats why we have so many fat ppl,easy calorie rich lifestyle+no exercise and it isnt hard to be fat.....been there done that.Im not advocating anyone riding for a living,heck Id advise against it these days for most ppl,but I was using it as an illustration....it took me around 2yrs to lose 35 lbs,those last 10lbs or so dont come off easily.So is cycling good for losing weight,sure is,just takes awhile and lots of miles.....count calories and it will come off faster,is it the total solution,NO.....but its a piece of the puzzle.Lots of options for those with families and obligations....and its doubtful cycling can be the one and only source of primary exercise for most,a more well rounded approach will prob work better.But,in the end, it still comes down to lifestyle change(s).
