Isn't there a safer way to lose weight?

I think the next week and a half are going to be "half nekkid" at least. They're predicting low to mid 90's with heat indices in the low 100's for my area until almost next tuesday (not the tuesday 3 days from now, but the tuesday a week and 3 days from now!), and I have no air conditioning. So if you see me on late, or not at all, these are the days I won't turn my computer on until at least 9pm...
