#raypeat talking about benefits of wearing orange lens glasses in 2002. 👌#bluelightblockers

Orange juice is not a health food. It's sugar water with a good publicist. One 8 oz glass = about 20 grams of sugar. That's 5 sugar cubes. And about half of that is fructose, the same sugar we're blaming for the fatty liver epidemic in kids. No fiber. No protein. No fat. Just sugar water with a pinch of vitamin C... Eat an orange if you must. Better yet, eat some eggs. Carbs are optional & not needed.

Great post. The case against saturated fat is actually this stupid.

I've migrated from eating cooked beef tendon over to this beef gelatin powder brand Saves room and time in the Instant Pot for more prioritized organ meat cooking 40-60 g of weighed beef gelatin powder sprinkled on meals throughout the day

Why so many carnivores notice better joints Cartilage ages mainly through glycation. Collagen in joint cartilage has a half-life measured in decades (estimates up to ~100 years in some tissues). Once formed, the cross-links from advanced glycation end-products (AGEs) stick around. The result is stiffer, less resilient cartilage that doesn’t glide or absorb load the way it used to. Most of those AGEs form endogenously from circulating glucose and reactive dicarbonyls, not from the meat on your plate. Beef supplies a direct countermeasure: carnosine. This dipeptide is concentrated in muscle and acts as a sacrificial scavenger. It reacts with methylglyoxal and other carbonyls that would otherwise bind lysine and arginine residues on collagen, reducing new AGE cross-links and protein carbonylation. Human data show carnosine supplementation lowers circulating AGE markers and improves glucose handling in people with diabetes. Eating the actual muscle delivers the compound in its natural matrix along with the protein and fat that support stable blood sugar. On a carnivore diet two things happen at once. Endogenous glycation pressure drops because glucose stays lower and more stable, and you continuously supply carnosine that mops up the reactive intermediates that do form. That combination plausibly slows the progressive stiffening of cartilage that most people accept as normal aging. It is not magic or a cure for advanced structural damage, but it is a coherent explanation for the repeated reports of less pain, better mobility, and fewer “old joints” once people stop eating the foods that keep glucose elevated all day.

There are essential fatty acids and essential amino acids. There is no essential carbohydrate. The body does need some glucose, mainly for red blood cells, which have no mitochondria. But the liver and kidneys can make all of it through gluconeogenesis, typically around 100 to 150 grams a day in adults, using lactate, glycerol from fat, and a small amount of amino acids. Carb tolerance still varies a lot from person to person, and my new book, The Carb Crisis, explains why. The evidence is clear: carbs are optional, not required. Preorder link in the first reply.

Resting heart is the new thirst trap It’s the sexiest thing about you Since 2021 I’ve posted about RHR: > 207 times > generating 366,220 likes > 78.3 million views > these numbers are X only Now it’s a mainstream symbol of high status People will adopt something if it helps them get access to sex, money or power. Resting heart rate before bed was my first big aha moment in my health quest. I discovered that it was the single number to rule all other numbers. RHR is the composite number for food, exercise, stress, routine, discipline, nervous systems, mood and more. It’s endlessly useful. I had to break RHR out of esoteric health and into status and social signaling. RHR needed to represent a person’s youth and vibrancy and signal genetic fitness. So I hit the topic from more than ten angles: > masculinity > cognitive performance > fertility > sexual health > discipline > will power > judgement > health > peer status > values > rebellion against status quo Others saw the social leverage and started working on their RHR to post. Press started picking it up, putting my name and resting heart rate in the headline. The science behind a lower resting heart rate is solid. It is a composite health marker of a person’s biological vitality. If you’re new to resting heart rate, here is a quick guide. Health is confusing, and overwhelming. But your heart makes things really easy. > a low resting heart rate before bed is good > a high resting heart rate before bed is bad If my RHR is 41 before bed, a perfect night sleep awaits: + asleep in less than five min + 4 hr of restorative sleep + 0 to 1 wake events + awake no more than 20 minutes That's the 99% percentile sleep performance for an 18 year old. As you age, it's increasingly harder to sleep. If you’re sleep is good, life is good. So here is where you can start: + finish all food 4 hours before bed + screens off 30-60 min before bed + finish caffeine around noon + avoid blue light, use red and amber instead + read a book before bed + have a 30-60 min wind down routine including walking, journaling, breath work meditation, talking to friends, a chill hobby, etc. Do these things and I promise every part of your life will improve.

A 19-year-old bought a raw cow thyroid online and ate about half of it. His resting heart rate hit 140, and he spent a week in hospital. Moral of the story: don't eat thyroid gland. That's how our Thyroid Special starts. Out now 👇

This is the third or fourth time I've tested a high fat, meat based diet and the last. My body just does not like it! 😳 The higher the fat, the higher my glucose and insulin, more inflammation, more and more pain in my body. No energy. Heavy tired legs. Never again will I eat a high fat carnivore diet. 😅 Animal based. - fruit, animal products, raw milk, low fat is where I feel my best and where my metabolic markers are best. So now for a gradual introduction of fruit and a lowering of the fat. 🍉🍇🍑🥩🥚 Sorry if my experience doesn't align with yours. We don't have the same body - obviously.... Four and a half years of experience and experiments have shown this to be true again and again. I thought I'd give it one more try now that my bowel can handle the high fat, but the other results were still the same. 🙄 Gradually increasing my pain, inflammation, misery... 🥹

Creatine is not just for bodybuilders. Older adults who lift and take creatine gain more muscle and strength than those who only lift. The usual dose is 3 to 5 grams a day. I'd treat creatine as a basic habit for anyone over 50 who lifts. And if you're not lifting yet, then just start there.
