<human>: Can you condense the text into a few key points?

There's been a weight loss challenge at work going on since May. I've lost a total of 7% of my body weight by counting calories and exercising. I've been living a healthy lifestyle and I haven't been trying to lose weight rapidly at an unhealthy pace.

With that being said, there are two weeks left and I'm 1.5% behind first place and $500. What kind of a diet is best to rapidly shed lbs in a two week period? This wouldn't be a permanent diet/lifestyle, just temporary. I already plan on supplementing my 20 miles on my stationary bike with jogging. I also plan on "sweating it out" the morning before.
<bot>: I'm 1.5% behind with 2 weeks to go in a weight loss challenge. I need to make up ground and then some.
