Protein vs Sarcopenia
Protein is essential for muscle and overall health. Dr. Gabrielle Lyon recommends 1.6g/kg/day for adults over 40 to combat sarcopenia. Resistance training is also important for muscle maintenance.
Protein vs Sarcopenia
This is Dr. Gabrielle Lyon. A medical doctor, she’s board-certified in family medicine, and has also engaged in research and clinical practice in the fields of geriatrics and nutritional sciences.
A quick note…
We’re going to be talking a bit about protein metabolism today, and it’s worth noting that Dr. Lyon personally is vehemently against vegetarianism/veganism, and considers red meat to be healthy.
Scientific consensus on the other hand, holds that vegetarianism and veganism are fine for most people if pursued in an informed and mindful fashion, that white meat and fish are also fine for most people, and red meat is simply not.
If you’d like a recap on the science of any of that:
- Protein: How Much Do We Need, Really?
- Plant vs Animal Protein: Diversity is Key
- Do We Need Animal Products to be Healthy?
Nevertheless, if we look at the science that she provides, the advice is sound when applied to protein in general and without an undue focus on red meat.
How much protein is enough?
In our article linked above, we gave 1–2g/kg/day
Dr. Lyons gives the more specific 1.6g/kg/day for adults older than 40 (this is where sarcopenia often begins!) and laments that many sources offer 0.8g/kg.
To be clear, that “per kilogram” means per kilogram of your bodyweight. For Americans, this means dividing lbs by 2.2 to get the kg figure.
Why so much protein?
Protein is needed to rebuild not just our muscles, but also our bones, joint tissues, and various other parts of us:
We Are Such Stuff As Fish Are Made Of
Additionally, our muscles themselves are important for far more than just moving us (and other things) around.
As Dr. Lyon explains: sarcopenia, the (usually age-related) loss of muscle mass, does more than just make us frail; it also messes up our metabolism, which in turn messes up… Everything else, really. Because everything depends on that.
This is because our muscles themselves use a lot of our energy, and/but also store energy as glycogen, so having less of them means:
- getting a slower metabolism
- the energy that can’t be stored in muscle tissue gets stored somewhere else (like the liver, and/or visceral fat)
So, while for example the correlation between maintaining strong muscles and avoiding non-alcoholic fatty liver disease may not be immediately obvious, it is clear when one follows the metabolic trail to its inevitable conclusion.
Same goes for avoiding diabetes, heart disease, and suchlike, though those things are a little more intuitive.
How can we get so much protein?
It can seem daunting at first to get so much protein if you’re not used to it, especially as protein is an appetite suppressant, so you’ll feel full sooner.
It can especially seem daunting to get so much protein if you’re trying to avoid too many carbs, and here’s where Dr. Lyon’s anti-vegetarianism does have a point: it’s harder to get lean protein without meat/fish.
That said, “harder” does not mean “impossible” and even she acknowledges that lentils are great for this.
If you’re not vegetarian or vegan, collagen supplementation is a good way to make up any shortfall, by the way.
And for everyone, there are protein supplements available if we want them (usually based on whey protein or soy protein)
Anything else we need to do?
Yes! Eating protein means nothing if you don’t do any resistance work to build and maintain muscle. This can take various forms, and Dr. Lyon recommends lifting weights and/or doing bodyweight resistance training (calisthenics, Pilates, etc).

Stop Cancer 20 Years Ago
Dr. Jenn Simmons shares vital tips on preventing cancer and inflammation, advocating for lifestyle changes and proactive health management at any age.
Get Abreast And Keep Abreast
This is Dr. Jenn Simmons. Her specialization is integrative oncology, as she—then a breast cancer surgeon—got breast cancer, decided the system wasn’t nearly as good from the patients’ side of things as from the doctors’ side, and took to educate herself, and now others, on how things can be better.
What does she want us to know?
Start now
If you have breast cancer, the best time to start adjusting your lifestyle might be 20 years ago, but the second-best time is now. We realize our readers with breast cancer (or a history thereof) probably have indeed started already—all strength to you.
What this means for those of us without breast cancer (or a history therof) is: start now
Even if you don’t have a genetic risk factor, even if there’s no history of it in your family, there’s just no reason not to start now.
Start what, you ask? Taking away its roots. And how?
Inflammation as the root of cancer
To oversimplify: cancer occurs because an accidentally immortal cell replicates and replicates and replicates and takes any nearby resources to keep on going. While science doesn’t know all the details of how this happens, it is a factor of genetic mutation (itself a normal process, without which evolution would be impossible), something which in turn is accelerated by damage to the DNA. The damage to the DNA? That occurs (often as not) as a result of cellular oxidation. Cellular oxidation is far from the only genotoxic thing out there, and a lot of non-food “this thing causes cancer” warnings are usually about other kinds of genotoxicity. But cellular oxidation is a big one, and it’s one that we can fight vigorously with our lifestyle.
Because cellular oxidation and inflammation go hand-in-hand, reducing one tends to reduce the other. That’s why so often you’ll see in our Research Review Monday features, a line that goes something like:
“and now for those things that usually come together: antioxidant, anti-inflammatory, anticancer, and anti-aging”
So, fight inflammation now, and have a reduced risk of a lot of other woes later.
See: How to Prevent (or Reduce) Inflammation
Don’t settle for “normal”
People are told, correctly but not always helpfully, such things as:
- It’s normal to have less energy at your age
- It’s normal to have a weaker immune system at your age
- It’s normal to be at a higher risk of diabetes, heart disease, etc
…and many more. And these things are true! But that doesn’t mean we have to settle for them.
We can be all the way over on the healthy end of the distribution curve. We can do that!
(so can everyone else, given sufficient opportunity and resources, because health is not a zero-sum game)
If we’re going to get a cancer diagnosis, then our 60s are the decade where we’re most likely to get it. Earlier than that and the risk is extant but lower; later than that and technically the risk increases, but we probably got it already in our 60s.
So, if we be younger than 60, then now’s a good time to prepare to hit the ground running when we get there. And if we missed that chance, then again, the second-best time is now:
See: Focusing On Health In Our Sixties
Fast to live
Of course, anything can happen to anyone at any age (alas), but this is about the benefits of living a fasting lifestyle—that is to say, not just fasting for a 4-week health kick or something, but making it one’s “new normal” and just continuing it for life.
This doesn’t mean “never eat”, of course, but it does mean “practice intermittent fasting, if you can”—something that Dr. Simmons strongly advocates.
See: Intermittent Fasting: We Sort The Science From The Hype
While this calls back to the previous “fight inflammation”, it deserves its own mention here as a very specific way of fighting it.
It’s never too late
All of the advices that go before a cancer diagnosis, continue to stand afterwards too. There is no point of “well, I already have cancer, so what’s the harm in…?”
The harm in it after a diagnosis will be the same as the harm before. When it comes to lifestyle, preventing a cancer and preventing it from spreading are very much the same thing, which is also the same as shrinking it. Basically, if it’s anticancer, it’s anticancer, no matter whether it’s before, during, or after.
Dr. Simmons has seen too many patients get a diagnosis, and place their lives squarely in the hands of doctors, when doctors can only do so much.
Instead, Dr. Simmons recommends taking charge of your health as best you are able, today and onwards, no matter what. And that means two things:
- Knowing stuff
- Doing stuff
So it becomes our responsibility (and our lifeline) to educate ourselves, and take action accordingly.
