<human>: I currently weigh 183lbs and my BMI is 25.5. My plan is to drop to 165lbs within 2-3 weeks. I only have so little time to do so because I have to weigh the right amount for my weight class. 

**current diet**

I've been eating:
-brown rice
-chobani
-chicken 
-fish
-veggies
-fruit
-lots of water

I weighed in at 190lbs about a week ago and dropped 10lbs within a week's time. I run at least 3 miles a day and also wrestle on top of that. I fluctuate weight a lot.

So it comes to the question:

**What and How can I speed up the process of lossing weight? I NEED to loose the weight fast. What should I eat, Do, and stay away from?

Can you summarize the given text in a few sentences?
<bot>: I need to loose 18 lbs within the time span of 2-3 weeks. What and How could I do it.
