Hadn’t seen this addressed yet, but 4kcals is the net energy for protein. 5 kcals is the gross energy, so the inefficiency of protein conversion to energy is already built into the calculation.
I agree“protein converts to glucose when in surplus” is an unhelpfully crude description of a more complex phenomenon.
I agreeProtein can convert to glucose even when not in “surplus” and some people consuming large amounts of protein (assumedly “surplus” amounts) have been shown not to convert any to glucose.
I agreeProtein to glucose is more a metabolic process that the body triggers or doesn’t trigger based on the need for glucose rather than the availability of “surplus” protein

I have searched Pubmed and Google Scholar in the past.
And, what I can not find is a trace of how the body handles a complete protein.
I once had a biologist friend of mine who Graduated from UCSD, and he once quipped to me that all proteins can be broken into their component parts. and, I balked at him: are they? if so at what rates? under what circumstances?
He and I went back and forth arguing for a while. Btw He lifts barbells regularly and his Backsquat is around 400lbs squats for sets of 5 (although he's still working on breaking a 500lbs. single after many years, and he's at around 175lbs. body weight, so - I pay him a good deal of deference, in general about lifting and its' constituent areas of concern.) He likes to assert himself when I share that I take in as few carbs as possible, because of the collateral effects. but, I digress.He and I went back and forth and neither of us found a relatively complete explanation of how the body actually handles proteins and amino. we know a great deal about them, and there's some correlation between the leucine requirement for Muscle Protein Synthesis and other general or body-wide effects. But, nowhere near a complete story, on if how or when the body partitions the delivery of proteins to any cells in particular.the many possibilities of how the body may handle proteins for repair and/or fuel are very poorly mapped. and many specific hypotheses are very thinly fueled by small amounts of factual information; too little to propel or sustain strong positions on what that means that someone should do.
I relate this line of inquiry to the problem of the Caloric Bomb Measurement versus the way the Energy pathways actually play out under ketosis.
the energy amounts possible in the caloric bomb measurement may be a unique value from the number of phosphors that may be delivered as ATP Phase 2.for example, during ketosis, there are a certain number of ketones that are excreted as waste as bad breath and funny-smelling pee. that is a dose of phosphors that were not delivered as fuel to any storage form in the body, thereby cutting the labeled calorie measurement that would be possible to some lower fraction value.the possibility of fuel delivery diverges from the actual. We are very unclearly aware of many of the possibilities of how the body may handle proteins and their component parts, but we aren't very close to an accurate map of how the body actually handles them in many specific cases.
So, I suppose I'm just saying - we know a bunch of things about nutrition in general, and insofar as the devil is in the details, there's a lot of controversy in the specifics.
I can deadlift my body weight for 10, and I still don't need to worry about any of this.This makes me think of Peter Attia's rule:
If you can't deadlift your bodyweight for 10 reps, you don't need to worry about any of this
Said originally in reference to supplements, but applies equally well to the complex biochemistry of amino acids.
I can deadlift my body weight for 10, and I still don't need to worry about any of this.
I heard this line before:
how much does a race car driver need to know about how an engine works?
Enough to win, and no more.
The range for performance is .8-1.5g per lb bodyweight. If you have a lot of excess adipose tissue, use estimated LBM instead of bodyweight.Based on the above contributions, It seems as though I may be over doing it.
I am a rather large human, 110kgs currentlt, so not sure what that puts my protein estimate at.
Maybe
I weigh 100kg, 100gram of lamb chops is 18g.
Other food I eat, peppers, fruit, white rice.
Based on the recommendations it seems I am eating too much. Maybe will reduce protein and add more carbs.
Digestion takes a protein and breaks it down into individual amino acids... I think that is what he was trying to say. Since obviously you don't eat steak and then your body takes steak and plops it in to your shoulder muscles so you now have muscles made out of sirloin (at the very least it would be a butt).he once quipped to me that all proteins can be broken into their component parts. and, I balked at him: are they? if so at what rates? under what circumstances?
For sure. MPS gets all the research... Because it is easy to measure. But minimizing Muscle Protein Degradation is the other side of the equation and may account for why eating more than the "Max" for MPS results in more muscle growth. So yeah, 20-30g of protein per meal may maximize MPS... But you will grow more muscle if you double it.we know a great deal about them, and there's some correlation between the leucine requirement for Muscle Protein Synthesis and other general or body-wide effects. But, nowhere near a complete story, on if how or when the body partitions the delivery of proteins to any cells in particular.
For example, 10 grams of new muscles a day is 8 pounds a year. That would be a very nice result for anyone running a hypertrophy program. And it's even worse than it looks with regard to energy balance, as 10 g of muscles includes about 2 g of proteins only. Muscles are mostly water.
This was more of a numerical example to illustrate that there is indeed no simple equation between amount of proteins consumed and muscles built. I'm not arguing that gains will be linear. I was just answering the original question:One reason I don't waste any mental bandwidth on trying to micromanage protein metabolism (other than just eating enough protein and paying attention to caloric deficit/surplus) is that hypertrophy is not linear, but episodic.
Why do you include protein in your calorie count?

I stopped counting calories and macros and have found much better health as well as much better results physically by paying more attention to eating foods that I know my body can easily Absorb as nutrients. I fast and then I eat until full and satiated and I’ve maintained an acceptable body fat, I’ve stayed at about 167lbs and I feel amazing. I eat mostly meat, a small serving of liver 5-7 days a week… eggs , raw butter, cod liver oil and fruit, occasionally potato’s . Lots of ribeyes and ground beef. Hardly any veggies no grains. I also try and get some fermented foods like kefir, sauerkraut, and apple cider vinegar. Ultimately the body doesn’t need carbs to survive, this has been proven by many people who thrive on carnivore diets, the fact that we can make glucose (fromI had a shower thought the other day, probably in close proximity to reading some babble about nutrition.
I know that diet is not really a talking point of strongfirst, but this seems like a nice corner of the internet where this matter could reveal some interesting discussions.
I have a question, of which I have searched the internet heavily for, and the only result I could find was some ramblings by Mike Mentzer about the fact that carbs and fat are what our bodies burn for fuel.
And the rest of the internet seems to agree that protein gets converted to glucose if it is in a surplus.
Why do you include protein in your calorie count? I thought the point of protein was building blocks for muscles, skin, hair, fingernails, organs, semen etc etc. If that is the case, which I believe it to be, why are we advised to include protein in your TDEE?
Many questions, maybe I should have just left this at 1 paragraph, but the more I think about it the more I am confused.
Truth.One reason I don't waste any mental bandwidth on trying to micromanage protein metabolism (other than just eating enough protein and paying attention to caloric deficit/surplus) is that hypertrophy is not linear, but episodic.
As I'm sure anyone who is an Intermediate / 5+ years of lifting will probably also share, the gainz aren't regular.
They're irregular.
Months can go by without much muscle gain, and then suddenly you'll gain 2 lbs of muscle in 1 month.

Not pasteurized.Ignorant question:
what is raw butter?
Not pasturized. Many are scared of it but pasteurization process kills some of the nutrients and can be the reason why some people can’t handle dairy. It’s also been shown to help prevent allergies as well as asthma (something I suffered from for years)Ignorant question:
