Mens Health - How many days a week should I exercise for weight loss?

[E.T.]

I do an hour a day of cardio. Last time I did an hour a day 5 times a week and lost about 54 pounds in 3 months. I injured myself and gained weight back so I'm trying to lose it again. I just finished up my 5th day and am contemplating on if i should exercise tomorrow or stick to my old routine of 5 times a week. I do very intense exercise as well not just walking around or something like that. I lost about 7 pounds this week and want to lose 20 more. Thanks
