it depends on your current weight, consult your doctor about how much you should lose, and then work out a plan to safely achieve your goals.
One can lose one pound by simply walking 5-10 miles per day for 3 days. On average, one should be walking 3-5 miles anyway so it isn't much further.

First off, it's very highly likely that said 300 pound man is obese. He can't bike 30 miles in a day unless it's downhill all the way, and that won't lose him any weight at all. Second of all, after how much time? How much weight does he lose a day, assuming he can ride a bike 30 miles a day? About 35 calories per mile, so about 1050 calories burned a day. 3000 calories make up a pound of fat. Assuming he just drinks water for 7 days, he'd lose 2.3 pounds a week.
You really should be under a doctors supevision when you try that, but you should be able to lose about a pound a day, provided that you keep up the exercise.

there is no way you should lose that much at your age. At maximum you should lose 1 pound a week. Walk or run for a little while each day, eat about 200 calories less a day
