Lol, lose 10 lbs in three months...probably. Most people can lose two pounds a week of real weight, not water weight. Anything above 2 is probably fake. I reccomend reading the posts about cutting on this site, and finding out how many calories you need to maintain your weight, then substracting 250 every week from that number. This is of course conbined with a 3-4 day workout schedule that includes both cardio and weight training.
