i need to weight loss partner

Like they always say a little bit of competition is good for the body and soul. I am a female,5.1 and i weigh 160lb. my bday is 31st of march and I want to loose a significant weight before then.

So the competition is; We all stick to a good healthy meal plan, exercise daily and we share our weight every two weeks.We can share tips daily.
Then we can see who the biggest loser will be.
