How big are you, and are you juicing?
That is a lot of calories, what are your goals here?
sorry....3000 calories is 12000 kilojoules.....
So is it 15000 you are after?
I would worry more about protein as grams per lb of body weight, rather than as percentage of calories. Proteins require more kidney usage than carbs or fats, so you don't want to up protein too high. Plus protein is absorbed differently, so larger amounts at a certain point aren't going to be beneficial.
Carbs, should be more tailored to your energy levels rather than percentage of diet aswell.
Types of fat, is important for health reasons and since you are going to be eating lots of them, healthier fats are going to be better for you from both a T level perspective and a overall health perspective.
this was awhile ago you posted, i am not sure why i am even replying but maybe someone else might read this and have use for it. : )
upping intake depends on your goals, and your methods.
if you are juicing, intake upping is easier if it's for the football team, it's got to be leaner if it's for competititons.
same rules apply if you are just trying to get bigger.....for the beach? for next month? for next year?
