I'm a very athletic 16 years old, i'm 5 foot 4 1/2 and i weigh 138 but i'm looking to lose 10-20 pounds in about a month...is this realistic, or possible rather? What do i need to do besides drinking a ton of water and staying active to achieve this goal? Any suggestions would be greatly appreciated!
I was also wondering about milk, does it help with weight loss as much as people say it does?

It's realistic, and you need a healthy diet and a strict workout. I suggest trying to go up and over expectations and try a boot camp like workout. I dont know about milk im lactose in tolerant

10-20 pounds is way too much to lose healthily in a month, and to be honest, too much for a healthy active 16 year old girl in general. A safe rate of fat loss is 1-2 lbs a week. Your weight seems pretty appropriate. If you want to lose a few pounds, I would suggest doing a few HEALTHY simple things like avoiding processed foods and focusing on filling up on fruits and veggies. My basic rules for healthy eating are no white flour, white sugar, hydrogenated oils, high fructose corn syrup, and fried foods. As far as milk goes, it is really great for you but it doesn't appear to help with fat loss as much as it was once thought. Good luck and love the skin you're in!
New note: Please avoid Ahmad's answer. Taking something is always a bad idea, and almost never produces results

try Michael Thurmonds 6 Week Body Makeover. Its great! I lost 7 lbs in the first week.

Hello there,
I can personally recommend weight loss hypnosis.
I've used the Rapid Weight Loss Binaural hypnosis program and found the weight literally dropped of me! In a month I lost 14 pounds just by listening to this program daily and what was really weird is I stopped craving sugary foods and started to want to eat healthily!
It really freaked me out when I went out for a pizza - I found myself ordering salad instead of a starter and skipping dessert! My friends were most bemused by it.
What I like about hypnosis is the fact that it works on a subconscious level - I've always struggled with weight loss in the past and found I couldn't stay motivated, but this, oddly enough, works!
Hope that helps you out :)
