Final Update:

From April 1 through June 1, I lost a total of 19.8 lbs. My opponent in the weight loss bet lost a total of 0.6 lbs. So I won in a landslide.

When we made the bet, we tried to set the stakes high enough so that we'd each be motivated:

If he won, I had to be his cameraman/lackey for a month as he has a fairly successful YouTube channel and wanted some help.

If I won, he had to trade vehicles with me for 2 weeks. He LOVES his cars.

So last Sunday, we made the switch and I now have his 2017 Mustang GT350 as well as his 2014 Ford Raptor (he gave that to me as well just so I didn't put too many miles on the Mustang). And he is stuck with my 2003 Ford Focus for the time being.

He is now in the midst of a 2 week daily vlog for the YouTube channel to document his day-to-day life including the driving of my car. If you're interested in seeing some of the fun, go to about the 39 minute mark of this video from the first day of his vlog:

Thanks again for all the input, motivation and support. Posting here daily definitely helped with accountability.
