Is it possible to shed 40 lbs in 8-9 months?!

Is it possible to shed 40 lbs in 8-9 months?

I am trying to reach my desired weight goal which I am 40 lbs away from at the moment. I am deployed with access to a great gym and am able to make pretty decent food choices in the chow hall... is it feasable if I am dilligent to lose it all before I come back in 8-9 months?

I'm 5'3" and 160 and would like to get down to 120

yes , you know I have the same goal!! 40lbs I lost 5 pounds in just 3 days (I know its body water and stuff but still!!) so its 35 lbs to go I exercise daily which is something I've never done before I feel the difference already and it's only been 3 days!!so I have 35 lbs to go yay!! and like I wanna lose it all in the summer as in now ! (3 months) hopefully I will it's all in your mind staying positive is the most important thing!! even if you have a set back..or binge on whatever just go on never give up and learn how to balance your diet, for example:if you dine out today and eat like creamy food or any fatty food try the next day to eat lots of fruit and veggies and less on the carbohydrate's or don't eat dinner or just eat yogurt or any healthy alternative and btw it's NOT about dieting it's about changing your life style for a longer happier healthier life! and sure the extra benefit of looking hot and attractive! lol..
and besides if your still a teen than your very resilient you'll probably lose the weight in a much lesser amount of time if you do it right...

well hope this helps and good luck!
