    If you generally eat just 2,000 calories a day, or, in my very bad case, less than that, are you supposed to increase your calorie intake in any sort of increments to reach 4,000?

    I'm terribly skinny, so I'm worried about any shock to my system. So is it advisable that I do so steadily, just like how someone trying to lose weight ought to pace themselves?

    My long-term goal is to be able to run a marathon. But not anytime soon of course. I'm patient. I can wait a couple of years to get my body adjusted and prepared.

    I don't really know the scientific part of it all, but yes, I think you shouldn't increase it all at once. When I was increasing I would add about 300-400 calories every week and I still felt bloated all the time until my body adapted, adding 2000 kcal at once for me would probably result in serious problemsicon_lol.gif.

    Here's what I would do:
    Add 300 calories (how you would divide it into Fat/Protein/Carbs depends on you) and keep that for two weeks and monitor your weight per week. If it does not increase, add another 300, until you see weight gain. If you have gained weight, keep the same calorie consumption until you start to see that you have not gained anymore weight. Make sure you are in a workout program to avoid gaining fat. Keep your workout routine pretty much constant to avoid any other variables.

    Good Luck!

    why do you want to increase to 4000 calories?
    if a marathon is your goal, just do the training accordingly and eat so you don't get any feelings of starvation.
    your calories intake will increase progressively as your training also increases.
    More important is to eat good stuff. You'll just feel it.
    And runners, like bikers or xc skiers need a lot of carb for quick energy before, during and after training. Protein is important also , and so is fat but in decreasing ratios.
    By the time you run a marathon, it may be that you'd be eating 5000 calories a day or 3500 . Your metabolism has a big say in that
    For athletes, nutrition is pretty much a black art, part science , part intuition, part coincidence ( like discovering a formula that really works well for you )

    How many times i had a super race result and tried to replicate exactly how i trained, how i ate, how i rested for the following events, only to fall flat on my face...lol.

    I feel bad for not saying 'thank you' for the responses. I didn't know I had any. Thank you for the replies.
