## Protein Ration Math Check

• Posted by a hidden member.
Just needing a sanity check here:

I currently weigh 175lbs which is 79.4kg

I figure I am around 18% body fat, so my lean body mass is around 65kg

An average of several sources says that when bulking I should consume 1.4g of protein per kg of lean body weight, putting my daily intake of protein at around 91g, or 3.2oz

If I use my full body weight, it jumps up to 112g per day, or 4oz - which is a theoretical quarter pounder (hamburger)...

Does this sound right, or do I need to learn2math moar?

I always thought that 1.4g per unit body weight was for pounds and not kilogrammes.

Last winter when I was designing my diet and routine I read (on bodybuilding.com, I think) that it's around 1.5 g protein per pound of body weight.

So, for you: 1.4*175 = 245 g of protein per day, which seems reasonable.

I needed around 165 g to maintain my weight and I struggled to consume that much. Re-check your sources and make sure to carefully read whether they talk about pounds or kilogrammes.

The numbers you see from various sources are rough guidelines only. Individual protein requirements are highly variable, and you'll only really be able to determine it using trial and error.

Keep in mind that more protein is not necessarily better. Its a bell curve.

Another irony to keep in mind is that you actually need less protein relative to your carbohydrates during bulking, than you do when cutting or losing weight. This doesnt necessarily mean you need less protein, just less protein relative to carbs.

BTW while your theoretical quarter-pounder might give you 112g of protein, a real quarter-pound of even good quality raw hamburger (like ground sirloin) will only yield about 22g of protein, and thats assuming your real quater-pounder has no fillers (in which case its not going to stick together very well).

I suspect that you won't need strictly 1.5 or 1.4 g protein per lb body mass anyway. As Jerebear stated, it's variable and you will only be able to really know what works for you through trial (hopefully no error). It's best to not grossly underestimate your required daily intake though. You thought that 112 grams were needed (half of what you theoretically (?) should be taking!).

Let me know what you decide...

I get confoozled with the numbers, as I hear folks talking about eating upward of 300g of protein per day - or about 10oz - that's a lot of meat!!

(god, why the fuck couldn't we have gone metric, having to convert between SI and US measure is \$&@&!!!)

I usually just keep it around a gram of protein per lb of bodyweight.

i tend to stick to just over a gram per pound as well. just what feels right really
