Ashley goes to Utah tomorrow and I will meet her there 5 days later. So I got to thinking, why not surprise her with a new me for Christmas? I figure it would take 5 lbs to really make a splash.
I've seen people lose more in less time on The Biggest Loser, so I know it's possible. But they're also HUGE and have all day to work out (not to mention $250,000 to motivate them to eat right).
That begs the question, could I lose 5 lbs in 5 days...without cutting off an arm, visiting the hospital or dying due to dehydration or starvation?
I think it's a question of math and physical stamina. I'd have to deprive myself of 3500 calories per day. The problem is that I normally consume less than 2500 calories per day (which means I also only burn 2500 calories per day). Even if I starved myself for 5 days straight and maintained my normal calorie expenditure I'd only lose 3.5 lbs. That means I need to work out too.
At a bare minimum I'd need to work off another 1.5 lbs, or 5250 calories, in addition to the calories I lose not eating. I can burn about 150 calories in 10 minutes on a treadmill, so that's only 5 hours and 50 minutes (just over an hour a day) of running to make up the difference.
Unfortunately, I'm left with the whole living until Christmas issue. To fix that, let's say I dropped my caloric intake to 1500 calories per day instead of all the way down to zero. If I maintained my current daily activities, I'd expect to shed 1000 calories per day, leaving me with another 2500 per day that I would have to exercise my way out of. In other words, to reach my goal of 5 lbs in 5 days, I would have add 2 hrs 45 min on the treadmill (or its equivalent) each day to the 1000 calories I avoid by dieting. That's starting to sound more feasible, especially if I broke up my exercise routine into a morning and evening workout.
I may just have to try it.
