Id bet you will lose muscle if you do that.
Men that do alot of cardio tend to have lower testosterone levels.

If they want the flab off, resistance training or cross training would work better.
More fat is burned during rest this way.

I know alot of people that want to lose weight and do the cardio deal, but I dont think that is the best approach.
Diet controls most everything, some slight modifications in diet will burn more calories.
For instance 35 grams of fiber would end up burning 250 calories.
Dont know how many calories that would burn on your run but for me at some very good intensity I would burn that in about 17 minutes on the cross trainer.
Just a simple thing like that would save you 17 minutes just by swapping foods around.

A gallon of ice water burns 150 calories due to the body taking energy to warm that water up, or replace the heat loss from the ice water.

Adding the fiber and ice water would equate to around 400 calories a day after around 9 days you would have lost a pound of body weight, or just over 3 lbs a month which in my mind is perfect.
Add in a little cardio or lower your calories by just 100 and at the end of just one week you will have lost a pound.
