I was watching this documentary about a 24 year old who was 6 foot 130lbs, his goal was to gain 5 lbs a week for 3 months, that would put him at 190lbs ,he was gonna eat 5000k daily, but when I saw that I was wondering is that even possible, im mean the guy is so underweight and he dosent workout at all ,just by diet he was gonna try that, I just didn't know if that's possible or not, I mean 5lbs a week that kinda sounds doable and at 6 foot 190 how much fat will he have ,almost like a bodybuilder in offseason then cuts up, if I was that guy I would go to a online weight gain calculator, freedieting.com has a good one ,I would put in his height and goal weight of 190lbs, whatever that calculator told him to eat in calories I would follow that, I couldn't imagine gaining 60lbs and still not weighing 200lbs lol
