What Occurs When You Eat 100 Grams of Protein At As soon as? – T Nation Content material – COMMUNITY


The Trommelen Research

Is 30 grams of protein the utmost you should use in a single meal? New analysis says no. Right here’s why.


A brand new revelation about protein simply dropped within the journal Cell (1). Let’s dig into it.

Individuals all the time say, “The physique can solely use 30 grams of protein directly!” Is that true? Nicely, think about consuming a 16-ounce steak. When you can solely use 30 grams of protein directly, you’ll discover steak-shaped deposits in your bathroom the subsequent morning. That doesn’t occur. So, the place does the steak go?

Extra protein helps construct larger muscle tissue (2, 3, 4), however is there a restrict to how a lot protein really goes into your muscle tissue? It’s not a 100% environment friendly course of as a result of constructing muscle is a gradual and labor-intensive course of. Analysis from the identical lab estimated that from a 20-gram scoop of whey protein, solely 2 grams is straight deposited as protein in muscle tissue (5).

The New Research

Dr. Jorn Trommelen got down to decide if there’s a restrict to the quantity of protein your physique can take in and use for muscle protein synthesis (MPS) or the method of stuffing amino acids into muscle tissue. He carried out checks on 12 wholesome younger males who consumed totally different quantities of a particular milk protein directly. This protein contained tracer-labeled amino acids so the researchers might monitor them across the physique and see the place they ended up.

Dr. Jorn had a number of speculations earlier than the examine started:

“It’s usually believed that solely 20-40 grams of protein is successfully used for constructing muscle, with extreme amino acids being wasted as gas (oxidation). I’m skeptical and hypothesize that the good thing about larger quantities of protein solely turns into obvious when accounting for the extended digestion time required for a big dose.”

So, what really occurred?

After lifting, the topics acquired both 25 grams of protein, 100 grams of protein, or a placebo. They carried out a single bout of whole-body resistance train taken to failure. Then, they acquired 4 steady isotope amino acid infusions utilizing intrinsically labeled milk protein. They took a bunch of blood samples and muscle biopsies over 12 hours.

The Outcome: No Higher Restrict to Protein Use?

Judging by this examine, there doesn’t look like an higher restrict to the physique’s capability to soak up protein and synthesize muscle protein.

WHAT? That’s wonderful!

In reality, consuming extra protein led to an prolonged protein-digestion interval, extra amino acid absorption, and ongoing launch into the bloodstream over the 12-hour interval. Moreover, there was a dose-response relationship: the group who consumed 100 grams of protein skilled the best muscle protein synthesis charges.

So, we CAN use extra protein at one time! However wait, there are a number of particulars to cowl.

Whereas it’s true that the 100-gram protein group outperformed the 25-gram group in nearly every little thing, this was finished after a brutal full-body exercise consisting of 10 submaximal reps (a ramp-up) after which units finished at progressively growing masses till failure.

What we don’t know is that if this extended response in muscle protein synthesis would’ve continued after a couple of exercise. Most definitely, sure, however to what diploma with a 100-gram dose? We don’t know.

Keep in mind, these topics had been younger and wholesome, with a sturdy response to protein consumption. This response decreases with age (through anabolic resistance) and in some illness states (6), so in the event you’re older or have some pathology, these outcomes might not apply.

Burning Protein

The quantity of amino acids that topics burned (oxidized) within the 100-gram dose was fairly small. Lower than 15% of the ingested protein was really oxidized, supporting the conclusion that a lot of the protein was used to make muscle tissue larger. Rating one other one for extra protein directly.

How A lot Muscle Was Added?

With only a single dose of 100 grams, they calculated that 13 grams (13% of the ingested protein) was included into skeletal muscle tissue. Whereas that appears small, comparatively, that is big. This exhibits that skeletal muscle tissue has a a lot larger capability to include protein (amino acids) than we thought.

Now, you may stroll out on a hypothetical limb and examine that to solely 2 grams from 4 20-gram doses, which clocks in at 8 grams of latest muscle tissue. Thus, this 100-gram monster methodology would provide you with an additional 5 grams of muscle. Nicely, we don’t have the power knowledge to assist that concept but. Perhaps it’s extra; nevertheless, over time, my guess is that it received’t add as much as massively extra muscle.

Modifications in Smooth Tissue Additionally?

Sure, this examine additionally demonstrated that muscle connective protein synthesis charges had been increased after ingesting 25 grams and 100 grams of protein. This means an anabolic response in connective tissue, too.

Connective protein synthesis charges had been increased following the ingestion of 100 grams of protein in comparison with the placebo situation over the 12-hour post-feeding interval, additional supporting the influence of protein ingestion on collagen synthesis.

This matches some earlier work (7). In each instances, collagen as a substrate wasn’t given as there’s different knowledge displaying that supplemental collagen might improve tender tissue adjustments (8-10). The takeaway? The opposite “connective tissue parts” had been additionally upregulated with solely the milk protein given post-training.

How Is This Analysis Helpful?

The grand revelation from this examine is that this: in the event you’re planning to embark on an epic odyssey of fasting, it is likely to be good to load up on protein beforehand.

Now, right here’s the professional from this examine – you’ve acquired extra flexibility on the subject of the frequency of your meals. However maintain on tight as a result of it means you’ll be chowing down on some severe protein parts in the event you select to go the less meals route.

Don’t get slowed down within the particulars. The primary thought is making certain you’re getting that protein quota locked down every day. Present analysis exhibits round 0.7 grams per pound of physique weight and probably nearer to 1 gram per pound of physique weight in the event you’re actually chopping energy (11-15). When you’re a 200-pound lifter, that clocks in at 140 grams of protein per day on the low finish and 200 grams on the upper finish.

By the best way, this examine additionally confirmed no adjustments in autophagy markers (recycling of used/misfolded proteins). So, eat extra protein.

However They Used a Casein-Based mostly Protein

For this examine, they investigated a milk protein that consisted of 20% speedy digestible whey protein and 80% slowly digestible casein protein, so you may speculate {that a} extra extended anabolic response to protein ingestion is exclusive to it being slowly digestible.

A examine printed this yr by the identical group confirmed no distinction between whey or casein when given earlier than mattress (17), so it’s unlikely that you simply’d see an enormous distinction with whey. Different protein sources would almost definitely present the same response, however the knowledge is much more sparse there.

Take Me to Church

Right here’s what Dr. David Church needed to say:

“This examine confirmed that muscle and whole-body protein metabolism may be elevated with increased quantities of protein. That mentioned, one of many details is the size of the post-prandial (fed) interval. It’s a ten-hour lengthy interval, and even then, the protein remains to be showing in circulation as indicated by amino acid concentrations nonetheless elevated above baseline. Fewer however bigger protein feedings all through the day are simply as efficient as smaller doses unfold evenly all through the day. That is one other strike in opposition to the concept of protein distribution being a big contributor to will increase in muscle protein synthesis all through the day.

Last Suggestions

That is nice information since we now have knowledge displaying that you’ve got extra flexibility in the way you distribute protein all through the day. No, this doesn’t imply you need to eat 100 grams of protein thrice a day. Nonetheless, it does present useful insights into how the physique responds to protein consumption and its potential advantages for optimizing muscle progress and restoration through a bigger however extra rare protein feeding.
