I very much doubt that's possible, safe, advisable or reasonable. Check the calibration on your scales....
If you need to rapidly and temporarily gain some weight it is possible to drink loads of water. But medically this isn't a great idea since too much water can actually kill you and 100lbs is a lot more than you could expect to gain without being dead. It would be like a whole child inside you.... I also don't suggest eating children.
according to one site, it's about 100 pounds a day (50 kg).
no you cant lose 100 pounds in 1 day
No, it is simply not possible to lose 100 pounds in one day.
normally you may gain/lose 2 pounds throughout the day.
Producers shoot for 3lb of gain per day in the feed lot
water weight
of course it all depends on exercise and diet. You can gain up to 3 pounds a day if you are not care full
i dont know about pounds you can gain but you lose about tree fiddy for every extra value meal
3 lb per day
you need to gain about 100. not lose. unless you are 10. why would you want to gain any anyway?
