“The Big Breakfast Study” !

Chrono-nutrition influence on energy expenditure and body weight (Ruddick-Collins et al., 2018) HT/ Robb Wolf

[Patron link]

“A growing body of evidence highlights the importance of the biological clock as a modulator of energy balance and metabolism. Recent studies in humans have shown that ingested calories are apparently utilized more efficiently in the morning than in the evening and this is manifest through improved weight loss, even under iso-energetic calorie intake.” YES!!!

Book recommendation: Why We Sleep

 

 

People eating 3 square meals a day shouldn’t be ingesting >40% of their calories late at night. <33% prior to sunset is more like it.

“The SCN of the hypothalamus, the ‘master clock,’ is primarily regulated by the light/dark cycles in order to synchronise the body to the light cycle or solar day…” but it also must by sync’d to the peripheral clocks! aka ‘food-entrainable oscillators’ (FEO).

Sure, caffeine and exercise can influence the liver and skeletal muscle clocks, respectively, but for full central & peripheral co-entrainment: FOOD and LIGHT in the morning (exercise and caffeine are optional for this).

New study: very low carb diets don’t impair high intensity interval training (Cipryan et al., 2018)

Effects of a 4-week very low-carbohydrate diet on high-intensity interval training responses (Cipryan et al., 2018)

[Patron link]

Relevant study design details: 18 young, healthy, moderately-trained males. First, this was a study on exercise performance. Had it been on glucose management in patients with type 2 diabetes or obesity, this is not the population they would have selected. Second, they needed at least a moderately-trained population otherwise both groups would’ve made big n00b gainz which may have out-weighed any differences incurred by ketoadaptation in 4 weeks.

 

 

Third, 4 weeks is a good duration for this kind of study because maximal ketoadaptation occurs in about 3 weeks and doesn’t get stronger thereafter (gains seen beyond 3 weeks are more associated with training effects).

On to the dietary protocols, results, and 2 other relevant new studies… but for that, head on over to Patreon! Five bucks a month gets you full access and there are many other options. It’s ad-free and you can cancel if it sucks 🙂

Intermittent fasting is homeopathy-level #nothingsauce

From all of the published human studies and “n=1’s” I’ve seen on online forums, intermittent fasting is #nothingsauce. Don’t @ me.

[Patron link]

When people lose weight via IF, it’s because of caloric restriction. There’s no metabolic advantage, and if anything, maybe the opposite. Restricting your feeding window to a very short period = metabolic mayhem.

2000 kcals in one sitting?

*smh*

 

 

I believe “early Time-Restricted Feeding” #eTRF showed promise in that recent study because of the “early” part; no so much on the “TRF” part. I believe this, in part, because the large majority of our population suffers from some degree of circadian arrhythmia. Social jet lag, too much artificial light at night, skipping breakfast, etc., etc. An EARLIER feeding window is one way to re-align circadian rhythms.

 

 

It STARTS with Sleep. Wanna improve body comp and make mindlessly better food choices? Fix your circadian rhythms.

Now onto the one of the weirdest, but potentially most revealing human studies on time-restricted feeding…

Obligatory glycolytic cells

Some cells lack mitochondria; they need glucose. And they don’t stop working during starvation because #gluconeogenesis.

[Patron link]

Red blood cells, renal medullar cells, and certain cells in the retina. Now do you see why it would be a problem if they stopped working during starvation? Hint: You’d die rather quickly.

Recommended textbook: Stipanuk or Gropper.

 

 

Those cells are unable to use conventional oxidative metabolism like the TCA cycle, ß oxidation of fatty acids, oxidation of ketone bodies and most amino acids, and the electron transport chain are all mitochondrial pathways absent from those cells.

Glucose dynamics during prolonged fasts

This is a somewhat complicated level of metabolism. Which tissues are producing what & how much, what are they burning & how much, etc., etc…

[Patron link]

After a few weeks, things begin to level out — we’ll pick it up there. Much of this is from a class I TA’d for in grad school, this book, and all the Cahill studies.

 

 

“The rate of glucose use at this time is around 90-100 g per day [remember, this is starvation, so all of that glucose comes from gluconeogenesis]. Of that, about 40 g is recycled via the Cori and glucose-alanine cycles and the remainder is ‘new’ glucose, ~18 g from glycerol and ~45 g from amino acids.”

Starvation ketosis and “priority” of brain fuels

“Priority” is a funny concept the fields of nutrition, metabolism, etc. For the brain, it is said to be glucose. It’ll use ketones when glucose is low and ketones are really high, like during starvation, but otherwise it’s just glucose. Why is this? One of my mentors had some great insights…

[Patron link]

 

 

“It seems that the loss of some energy as ketones in the urine is the price we pay to provide the brain with a suitable fuel. But there are a number of unanswered questions about brain fuel use. Why does the brain not use free fatty acids? The usual answer given is that they are not transported across the blood-brain barrier fast enough to be used as a major fuel and this is probably true. However, why did the brain not develop a suitable transport system, or localized store of glycogen for that matter.”

Metabolism of starvation/fasting =/= low carb diet

The Biology of Starvation (intro)

The Biology of Starvation: Renal Gluconeogenesis

[Patron link]

One of the major [obvious] differences in metabolism between fasting and low carb dieting is nitrogen metabolism… because you’re eating protein on a low carb diet, not so much while fasting. During fasting/starvation your body tries to downregulate the urea cycle because you can’t really afford to be ‘wasting’ amino acids/protein. I bet you never thought about the muscle-sparing effect of fat-derived fuels like that!

 

 

“Glucose production in starvation” is important because you need to make all of it and reduce the use of it.

7 Worst Heart Health Sins (Page 20)

I read this on a magazine cover and my level of impending disappointment rapidly increased as I approached page 20. Aaaaand….

[Patron link]

It wasn’t horrible! Could use some tweaking, but hit a lot of important points and didn’t say “NO RED MEAT EVER.”

1/ You sneak a smoke.

DUH. Smoking cigarettes is the worst way to get your nicotine hit imaginable. Use a patch, chew nicotine gum, suck on a lozenge. Just. Don’t. Smoke. It also ages your skin faster.

 

 

2/ You skip your walk.

BOOM! We all know the power of a good walk, amirite? Get sunlight and fresh air, get off your butt as often as possible!

Diet X DESTROYS Diet B in Protein-Matched Ad-Lib Feeding Study

DESTROYS!

[Patron link]

With language like that, you’d expect to see a pretty big difference between the two diets. I mean like, really big difference.

So I clicked the link. Aaaaand #nothingsauce.

 

?(????)?

This study was similar to: “Carbs: Low vs. Lower” where it was shown that many people do just as well losing weight on a low carb diet as they do on a ketogenic diet.

The study was actually quite good, but “destroys” is not the word I would’ve used, especially since the destroyer dieters lost only about 25% more fat mass (P=0.083) and FOUR TIMES MORE FAT-FREE MASS (P=0.054).

Need vs. Optimization: Omnivores & Carnivores.

Humans are omnivores but does that mean we need to eat plants AND animals?

To address this, we first need to ask 2 questions:
1) need for what?
2) need vs. optimization?

STORY TIME

Scientists were determining the amino acid requirements of cats by feeding them semi-synthetic diets with various levels of each amino acid, one at a time. Tedious. A lot of cats x a lot of amino acids x a lot of levels of each amino acid = a lot of work. What made it even more difficult (and equally more interesting) was that they didn’t know what they were looking for — this was long before we knew what we know now about biology.

Tyrosine

Funny thing, when they got to tyrosine: below a certain level and their black cats started turning red! At an even lower level, certain neuroloogical abnormalities set in. So, how much tyrosine do cats need? Enough to maintain their beautiful black coats? I think we can all agree that the level which induced neurological abnormalities was too low. What about fur color?

 

What if female cats prefer males with beautiful black coats? So the males have a better chance at reproducing if their diet is at the higher level of tyrosine. I’d say fur color is pretty important in this #context! [how ya like ‘dem apples]

Need vs. Optimization

Note: this occurred over the course of weeks-to-months, not hours-to-days.

Note (2): unlike humans, cats are obligate carnivores. Real, actual, carnivores.

 

 

Arginine

Below a certain level of arginine and the cats looked dizzy, wobbled around, and some of them died.

Not weeks-to-months. Hours-to-days. This is what it’s like to be a carnivore. They NEED to eat meat or die rapidly (this is one of the few examples of an acute nutritional deficiency causing severe toxicity in the entire animal kingdom).

Cats have an inability to downregulate protein degradation and need arginine to dispose of the nitrogens via urea cycle. Humans just reduce burning proteins when protein intake is low.

 

 

Part 2Lobsters are omnivores and arginine is weird.

Lobster tail is rich in arginine (this might be what gives it a bit of a sweet-like flavor). If lobsters are fed an arginine-deficient diet, they go cannibal and eat other lobsters’ tails!

What does this say about lobster arginine requirements?

Need vs. optimization: they’re perfectly healthy, but is preventing cannibalism a “need?”

. .  .   .     .        .             .                     .

 

 

So, I ask again: Humans are omnivores but does that mean we need to eat plants and animals?

One retrospective study showed stroke victims who had consumed blueberries the day before showed significantly less cognitive decline post-stroke than those who hadn’t. Blueberries. Not green tea, blackberries, or dark chocolate. Blueberries. Do humans need to eat blueberries?

What if this was confirmed in a double-blind RCT? Is preventing post-stroke cognitive decline a need or an optimization?

Which is more important to you?

I didn’t have it in me to put this behind a paywall because while I think the answer is getting simpler & simpler (eg, SunlightHunger-Free Diet[s] and DietFitshot Blue-Blockers, etc.), fad diets are getting weirder & weirder. Just eat like an adult.
