BIG - don't want to bring you down, bro, but there is no way in hell you can drop 60lbs of fat in 3 months.
The only way you could do it is, if you bloat yourself with water starting about a week before your initial weight-in and then just drop the water weight with the lard. Too bad I didn't see this thread on time to give you this golden advice
But for the next challenge, if you want to make the big money - get your water weight up beforehand!
Why you can't drop 60lbs in 3 months - simple math. A pound of fat is 3,000 cals. In your best estimate you could burn 3,000 cals/day if you add some exercise, but that would leave you with a total of 90,000 cals spread over 3 months or 1,000 cal intake per day. In other words, you must eat 1000 cals every day and burn 3000 cals every day to lose 60lbs of fat in 3 months. Good fukin luck with that
Apparently you've never ate on deficit or you wouldn't have those dreams of dropping 60 in 90. If you are serious about losing some lard, you need to focus on more obtainable and long-term-sustainable goal like 1.5-2lbs per week. Or start saving for a Rascal.
