i would go super low carb during the week, maybe 25g-100g which is low for me... weekend i load up, dont really count, just have at it...
carbs can make you fat, sitting around...
or they can make you strong, tearing it up...
i like to eat good tasting food so i tear my shit up...
as a note: i do zero cardio, but my job is extremely physical!
when i load up its usually to either fill out or to lift at a meet/ or PR....
to fill out i will keep my carbs VERY low for a week, and then load up 24hrs before a photo or whatever.... sodium is OK for me here... but we are all different...
for a meet i dont go as low, but i have to make weight, and i weigh in usually 24hrs out and after i weigh in i eat EVERYTHING in sight... i make weight at 148 and may be lifting at 155ish...
BUT, if you diet too much leading up to this, you will not be able to handle dirtier calories...
