That would depend on how much you want to lose. It's a lot, then 2 months might not give you enough time.
It's generally figured unsafe to lose more than 1-2 pounds/week; in two months, I'd say you could lose 10-15 pounds, safely, by implementing a good diet and exercise program.
what do you suggest i do?
Fast weight loss is not good for you, and while there are ways to lose quickly, most likely, you will gain the weight back, once you go off the diet.
There is a diet call Fat Loss 4 idots, i just started it 5 days ago and have lossed 6 lbs, maybe you should try it.
