The feedee gains almost 100lb in 6 months (not sure how that's possible)  Actually easier than some might assume.  Note: In this calculation I am not including the theories of reduced/increased gains/losses etc. that come when gaining or losing weight. I do realize that someone who is heavier will use more energy (and therefor burn more calories) than a lighter person while doing the same activity. This is just a rough calculation - I'm a political science degree, not STEM, so feel free to correct my math if that applies.  So, considering that 3,500 calories is equal to 1 lb. of fat, that means over the course of six months, they would've had to consume an additional 350,000 above their normal daily intake for maintaining. Let's just use the standard 2,000 calories per day for their TDEE to maintain.  I'm cheating a little and using July-December as my 6 months, so that throws in a few extra days for a total of 184 days (from July 1st to December 31st). Since those 350k cal. are spread out over 184 days, that comes to a caloric surplus of 1902.2 per day. For most of us, that seems like a hell of a lot, but we see it all the time where these "people" are consuming well over two or three times what they should. Essentially, it comes out to eating about 3900 calories per day as someone who requires about 2000. That's a lot more believable when broken down, rather than just hearing the whole 100 lbs. in 6 months thing. And if you're not doing any sort of movement or exercise (which I doubt any of these are), then it makes it even easier to pack on the pounds over a short period of time.    > The feedee gains almost 100lb in 6 months (not sure how that's possible)  Actually easier than some might assume.
