No i'd say you'd gain closer to 10. Then it will slow down as you get heavier but even 0.60 lbs gained a day means you're a fat piece of shit...These big cvnts aren't 500-600 lbs for nothing
Have you ever competed?
After you compete most people eat way over their calorific intake for days without gaining any additional body fat, a rebound in water weight yes, fat ,no
Your body isn't efficient enough to convert everything you eat into energy and fat
Don't believe me, go and eat two large tins of sweet corn and report back on your shit content.
