in Goal: Maintaining Weight
Hello everyone,
I need some explanation on a confusing issue I've come across. I redid my macros via IIFYM and came up with the following:

CARBS PROTEIN FAT TOTAL CALORIES
Grams per day: 303.3 160 56 2357

this results in a 51, 28, 21 percent split for maintaince. Yeah, that doesn't seem right to me.

Via MFP in tyring to achieve a 40/40/20 split:

CARBS PROTEIN FAT TOTAL CALORIES
Grams per day: 235 235 52 2357


Both of these seem completely off to me. I mean, mathematically speaking they make sense, but at 160 lbs 235 grams of protein is insane!! Any input would be great, as I'm really confused what to follow at the moment.

    Set your macros based on your body mass, not a % of caloric intake. 1-1.2 g of protein/lb lean body mass, and 0.35 g of fat per lb total body mass. Fill the rest with carbs. http://www.myfitnesspal.com/topics/show/819055-setting-your-calorie-and-macro-targets

    neither...

    not sure how you got your numbers for the 40/40/20 split...

    I was always told you need 1gram of protien for each pound of LBM or 0.8 grams per lb of BW...so that means 121grams of protien which is what I eat...which ends up being about 25%...

    Then fats are LBM x 0.35 x 9
    The rest carbs

    and if you put your stats in MFP they line up with the numbers above...carbs @ 250g, Protien @ 125g and fats @ 56g...which are quite similar to mine...but I do 50/25/25

    Why not? That sounds perfectly reasonable and -- to the extent that looking at macros by % of total calories is useful anyway -- pretty much within the generally advised ranges, which are 40-60% carbs (you're right in the middle of that, dude), 15-25% protein (fair enough, most of us on here like to eat more protein and think the advice given to people generally doesn't apply very well to people who are training hard); 15-30% fat (again, right in the middle).

    ^ There's nothing about the above that seems unreasonable to me.

    Okay, I was just making sure. To me, that seems like alot of carbs, but im pretty new to the whole macro idea. So, from what I am gathering, a 50/25/25 is a good macro split to maintain on?

    That's my split and since I get more carbs now I find my lifts have gotten better and heavier easier if that makes sense...

    if you dont want that many carbs do 40/30/30 instead?

    The first ratio didn't seem unreasonable to me either.

    If you don't want to be super strict with it you could follow also what another poster said about 0.35g per lb bodyweight for fat, and 1g per lb lean mass, (as a minimum target I'd say, not a limit) Then filling the rest of your calories with carbs. There's nothing the matter with higher carb intake, especially if you're exercising.

    Although plenty of people get on with very different macro ratios. These are just guidelines based on common ones. If you're new to counting macros the best thing you can do in my opinion is play around with a few different ratios and go by which ones suit you and your goals best. There is no one size fits all, which is why you have the option to change it manually.

    Sounds right to me...

    40% of 2,357 calories = 942.8 calories
    942.8 calories / 4 cals per gram = 235.7g (so that would be your carbs and fat.)

    20% of 2,357 calories = 471.40 calories
    471.40 calories / 9 cals per gram = 52.37g (so that would be your fat.)

    The question is why you choose the 40/40/20 split and does it align with your goals?

    Edit: I guess I should have read your OP a bit better! You know they make sense maths wise...

    Nothing wrong with 50/30/20.

    If that's you getting your protein and fat minimums then, lucky you - you get loads of tasty carbs. Wish I had your issues - I had to cut mine to 30% for my cut :(

    The issue with calculating macronutrients strictly in terms of percentages is that as calories may go up or down you could then be adjusting macronutrients beyond or below where you would ideally like them.

    50/25/25 may be a good macro split for YOU to maintain on but depending on another persons stats and activity level it may not be a good macro split for THEM to maintain on.

    Regarding that being "a lot of carbs", if you find that you would prefer more fat and less carbs then you can simply hold calories the same (assuming they were correct to begin with) and reduce carbohydrate in exchange for fat until you find that your personal preference have been met.
