Or tell me it’s impossible/unhealthy. Either way.

I made a bet Nov 1 that I could go from 240 to 210 by Dec 31st. I am currently 225 on Dec 19th. I need to lose 15 lbs in 13 days. Is this possible to do by ways of losing water weight, like how fighters make weight then gain it all back? Keep in mind I’m a 5’ 11”, 33 year old fat guy not a world class mma fighter. This is also not life changing money, just $500 bucks between friends but I obv would like to win.

Is something like this possible(maybe on a smaller scale with less risk)?

tldr link:
(last 5 days)
Sunday – 2 gallons
Monday – 1 gallon
Tuesday – 1 gallon
Wednesday – .5 gallons
Thursday – .25 gallons
Friday – No water till after weigh-in at 5PM.

Plus no carbs or salt. And hot baths plus sauna last 2 days.

Not impossible, not healthy
but hell of a challenge and I would give it a whirl!!! I think being a fat guy actually makes it easier.

The trick is to buy a different scale than what you weighed in with.
This one should do it.

Disregard the 2star rating for inaccurate readings, it's 5stars for winning weight loss bets.

In most cases a water weight cut is cheating.

Cutting water weight, not cheating. New scale, cheating.

That $500 may help pay for the passing of those kidney stones...

Oh **** is that likely to happen? Cause if so I quit

It's possible, probably not likely. Dehydrating takes some time off your life, regardless if it gives you stones.
