when I was at 4800 cals ed and trying to break 5k one of the vets on here told me it would be the best thing I could do and I would be very happy with the results and I have. my buds told me the same and thats when I was just over 200lb. If you guys think 5000 cals is too much than I think you are not eating enough. and I know more than a few people who have competed nationally. one of them still does. they may not be my best friends but I talk to them enough to get tips.
