I'm averaging about 300g a day, is that too much? That's at about 3,000 calories. 6'0" 200lbs
1g per lean body mass
It might not be necessary to consume that much protein but I wouldn't call it too much.
I usually aim for 250-275g... I don't really see the point in going higher than that because then it's at least 40% of my caloric intake.
300, you're straight.
It's not going to cause any problems will it?
I just figured out my baseline macros, and did a google spreadsheet... would you mind taking a look? I think I'm really low on fat =\
lol my macros without dinner (it's variable) figure to 1700c 236g protein 149g carbs 13.5g fat
Sooo... your dinner is usually about 1300 calories?
So if 65g is from protein....that's 260 calories...the other 1000 is?
That's the problem that I'm having - dinner is different every night, and I'm terrible at keeping track of how much I eat and what the macros are comprised of. I guess 1300 calories is a little high for my dinner estimation
I've looked at certain caloric intake calculators, and I'm supposed to be around 3,000 a day so that's what I've been aiming for. Maybe go to 1% milk for the shakes during the day, and add some olive oil to my tuna for lunch?
I guess I should go through and re-read the nutrition thread again
A guy at the gym told me i need to be getting at least 380g of protein a nite
I'm 5'11" and 180ish give or take
I'm 6'3" 201ish, so I should be taking in about 50g per day then
just make sure you're eating enough fiber to prevent kidney stones.
Why would excess protein cause kidney stones and, if that were the case, how would fiber prevent this all from happening?
Edit: Did some research...looks like you have to be genetically predisposed to it and it's remedied by a proper intake of calcium.
wtf.... are you just drinking straight up protein shakes and then eating a bagel w/ cream cheese or something? i don't see how aybody could only get 13.5g fat out of 236g protein worth of food.
I'd kill myself.
Protein and kidney stones requires a pre existing kidney issue to cause any worry.
I forget the basic physiology of it but excess protein is stored as fat.
it can't be used for energy the same as fat and carbs?
Anything above maintenance of calories has the potential to be stored as fat. Every macronutrient, not just protein.
And define 'excess'? According to what? What is excess protein? What is excess carbs or excess fat?
wasn't it like 1-2x ur bodyweight? anymore and it just turns into fat. So 300g at 200lb should be fine.
From my Physiology book
"Aside from being the major source of building material for the body, protein may be used as a source of heat and energy, providing four calories per gram of protein. However, this energy function is spared when sufficient fats and carbohydrates are present in the diet. Excess protein that is not used for building tissue or energy will be converted by the liver and stored as fat in the body tissues."
Wilmore, Jack H. Physiology of sport and exercise. Champaign, IL: Human Kinetics, 2008.
'Excess' protein would be anything over LMB x 1.3. The other two questions are off topic and since your statement is true, they can be answered by the fact that total muscle stores of glycogen exceed the capacity of the liver roughly 5 times (totaling around 300-500 grams). Fat deposites pretty much speak for themselves. Its still unknown how much protein the body can utilize at once but as of right now its believed to be around 30-50 grams, way less than fats and carbohydrates. Its a lot easier to put a cap on the word 'excess' for protein than carbs or fats.
So if a 200lb person (person A)at 15% bodyfat ate 300g of protein and enough carbs and fat to be at maintenance, and person B, also 200lbs at 15%, ate 200g of protein and enough carbs and fat to be at maintenance, person A would put on more fat?
Thats an EXTREME over simplification. This does not take into account the fact that the body will use protein to make glucose first. It's excess glucose at a time when little energy is needed that leads to lipogenesis. You are also forgetting that protein's in general take much longer time to digest and assimilate compared to other macronutrients. Even if no other macronutrients were present, blood glucose would never be all that significantly elevated i.e. there would be no blood glucose spikes, but rather more of a sustained release. This IMO is actually ideal.
According to who?
So someone with 100lb LBM eating any more than 130g protein a day (520 cal) would get fat???
Sorry, the logic does not follow.
gluconeogenesis occurs with excess protein but that is not the same as being converted directly to fat. go go jermyd
