Agree with the others above. Sounds like a really unhealthy crash course. I've been trying to bike a lot and eat healthy this year, and I've lost about 17 pounds in 5-6 months. I think you need to seriously moderate your plan of attack and be more reasonable. I started around 215 like you; I don't buy the "big guys lose fast" or "my body's just that way" arguments. You need to take a rational, sustainable approach to your long-term goals; stated differently: you can't achieve your long-term goals in 1 month!! I applaud your efforts but you really need to rethink the approach and timeframe.
