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….

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!

Critique and analysis.

They did two very small (n=10 & n=7) 2-week long studies of low carb, high protein. Carb/fat/protein was 4/72/24 compared to 20/42/18 at baseline. There was no control group, so the results were compared to baseline.

Cracking into the Food-Entrainable Oscillator (FEO)

Scheduled meals and scheduled palatable snacks synchronize circadian rhythms: consequences for ingestive behavior (Escobar et al, 2011)
Big hat tip to Robb Wolf for bringing this to my attention. If you’ve been following my more circadian-related stuff, I’ve done a lot of tip-toe’ing around the FEO (food-entrainable oscillator). Tl;dr: sunlight entrains the master clock in the SCN via well-known mechanisms; food entrains peripheral clocks (riddle wrapped in a mystery inside an enigma). 
Ideally, to ensure co-entrainment of the central and peripheral clocks, breakfast and sunshine in the morning, around sunrise.
We know bad things happen when you do the opposite and why you Shouldn’t. Do. OMAD (one-meal-a-day).

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).

3 strikes – funny

Weight reduction does not induce an undesirable decrease in muscle mass, muscle strength, or physical performance in men with obesity: a pilot study (Kim et al., 2018)

Cut & paste abstract. Literally.

“To date, there have been no reports on whether weight reduction causes decreases in muscle mass, muscle strength, or physical performance that could lead to health problems. Thus, in this pilot study, we investigated the appropriateness of the changes in muscle mass, muscle strength and physical performance after weight reduction.

Obese men who completed a weight reduction program to decrease and maintain a body mass index (BMI) of less than 25 kg/m2 for one year were recruited for the study. One year after the completion of a weight reduction program, the participants’ muscle mass, muscle strength, and physical performance were compared with those in a reference group composed of individuals whose BMI was less than 25 kg/m2. Whole-body scanning was performed using dual-energy X-ray absorptiometry to analyze muscle mass. Handgrip strength and knee extensor strength were measured to evaluate arm and leg muscle strength, respectively. For physical performance, a jump test was employed.

The results showed that the biceps, triceps, subscapular, and suprailiac areas of professional fashion models were significantly thinner than those of women in general (p<.001), and that their waist size was also significantly smaller (p<.001). However, hip circumference showed no significant difference. Body mass index, waist-to-hip ratio, and body fat (%) in professional fashion models were significantly lower than those in women in general (p<.001), while the body density in professional fashion models was significantly greater (p<0.001).

Weight reduction participants showed an average reduction in body weight of -16.47%. Normalized arm muscle mass and handgrip strength were significantly greater in the weight reduction group than in the reference group; however, no significant differences were detected between the two groups with respect to the other variables. After one year, there were no significant differences between the two groups.”

Wait, wut

O_o

I’m blaming that one on the journal. They made a mistake — strike 1. I read it twice before laughing out loud.

 

Table 1.

Given the title of the paper… statistically significant reductions in all of the muscles they measured. Strike 2.

I reiterate: given the title of the of the paper, statistically significant reductions in nearly every measure of performance. Strike 3. Strikes 2 and 3 are on the authors.

You’re OUT hahaha

Chronobiological theories of mood disorders

Another comprehensive review article: Chronobiological theories of mood disorders (Zaki et al., 2017)

[Patron link]

Here is my summary and opinions about it.

Tl;dr: the authors cautiously explored the bidirectional and/or causal effect of sleep & circadian disorders vs. mood disorders. I appreciated their caution but a lot of the evidence presented suggested circadian arrhythmia as a causal agent.

Tricyclic antidepressants (TCAs) and selective serotonin reuptake inhibitors (SSRIs) don’t address underlying circadian and seasonal rhythm dysfunctions, so patients are usually prescribed these meds indefinitely.

In the future, they see light therapy and melatonin receptor agonists as better treatments. I’d say an outdoor walk sunlight exposure after breakfast in the morning, blue blockers or nix artificial light at night, and instead of melatonin agonists, consider serine.

“The master clock controlling chronophysiological rhythms of theand body organs is located in the SCN…” VIP and AVP are abundant in the SCN! I knew it! LOL

“Humans’ endogenous rhythmic activity has a period slightly longer than 24 hours, hence, it needs daily entrainment to 24 hours with zeitgebers.”

Translation: SUNLIGHT AND BREAKFAST IN THE MORNING

Evidence favoring circadian and sleep disorders as causal agents in mood disorders:

It STARTS with Sleep

In Nedeltcheva’s notorious weight loss study, those assigned to shorter sleep duration (5.5 hours) lost more muscle and less fat mass than those assigned to adequate sleep duration (8.5 hours). Same diet + same calories + circadian arrhythmia = no bueno.

*I’d say 8.5 hours can be called in this context. I like saying, seasonally, 8-9.5 hours of darkness, most of which should be spent sleeping. Others say 7-9 hours is adequate and <7 is inadequate. I agree with that, too*

Similar outcomes are seen in any number of sleep restriction studies. Figuratively, everything goes down the toilet. But that’s only half of the story.

There are a couple randomized intervention studies on intentional sleep extension and the results are very cool.

 

 

The effects of extended bedtimes on sleep duration and food desire in overweight young adults: a home-based intervention (Tasali et al., 2014)

They recruited habitual under-sleepers (<6.5 hours), recorded their sleep behaviors for a week, then gave them individualized behavioral counseling on sleep hygiene with the goal of extending their sleep duration to 8.5 hours. It worked: they were less sleepy, felt more vigorous, and spontaneously ate less sugar and fewer calories. Had the intervention lasted longer than 2 weeks, we would’ve seen body comp improvements as per Nedeltcheva’s study results. IT STARTS WITH SLEEP.

Beneficial impact of sleep extension on fasting insulin sensitivity in adults with habitual sleep restriction (Leproult et al., 2015)

Similar set-up as above: 2 weeks initial monitoring, then 6 weeks where they slept about an hour longer. It worked. Total sleep time positively correlated with indices of insulin sensitivity.

Feasibility and emotional impact of experimentally extending sleep in short-sleeping adolescents (van Dyk et al., 2017)

Kids who normally slept 5-7 hours a night increased that by ~70 minutes for 5 weeks. It worked: reduced symptoms of sleepiness, anger, and confusion! Seriously?

Seriously.

Most of these studies basically just told the participants to go to bed earlier (in evening chronotypes) or sleep a little later (in morning chronotypes). It was individualized and not pharmacological. That means you can do it.

Check it: Blocking nocturnal blue light for insomnia: a randomized control trial (Schecter et al., 2018) CROSSOVER STUDY. Tl;dr: it worked. Blue blockers, FTW.

Start paying attention to REV-ERB alpha

Hey team, remember when I was making wild predictions about REV-ERB alpha?

[Patron link]

“Food for thought: an endogenous ligand of Rev-erb is heme (the iron-binding element in red blood cells). Heme is degraded into bilirubin.  Elevated levels of bilirubin cause jaundice. A treatment of neonatal jaundice is exposure to blue light. Blue light is a major regulator of circadian rhythms and Rev-erb is an executive-level player in this game. The primary mechanisms of blue light appear unrelated in these two models (melanopsin activation vs. bilirubin photoisomerization), but seem intertwined, because heme activates Rev-erb.  Cool.” (From HERE)

and statements:

“Pharmaceutical-grade circadian augmentation = unwittingly better-timed meals? Improved body composition? …they were eating more and moving less. … One possible mechanistic explanation comes from mice lacking Rev-erb in skeletal muscle (Woldt et al., 2013). Mitochondrial biogenesis was impaired and exercise tolerance was reduced in these mice. Spontaneous physical activity was lower; thus, it stands to reason that Rev-erb agonism may improve skeletal muscle mitochondrial function. This isn’t entirely consistent with the drug study, but pretty close.” (From HERE)

 

REV-ERB is really really good for skeletal muscle.

Beta-hydroxybutyrate inhibits activation of the NLRP3 inflammasome.

 

 

Well, so does REV-ERB alpha! In a new study, knocking down REV-ERB alpha jacked up NLRP3 and pharmacologically enhancing it attenuated NLRP3 (Pourcet et al., 2017). The consequence of this in REV-ERB KO mice injected with LPS was hyper-inflation. No bueno. Mice given the commercially-available REV-ERB alpha agonist “Stenabolic” were protected.

I’m geeking out about REV-ERB alpha & SR9009. And fwiw, I don’t think anything will actually fully replace the benefits from actual physical activity and/or exercise, although it’s very hard for some people; eg, COPD, CHD, etc. In those populations, if they can’t exercise enough to really improve their condition, something like this might help. But I’m sure perfectly healthy people are going to try it. If you do, let us know in the comments!

Breaking: Melanopsin Discovered in Human Adipose Tissue

PRELIMINARY FINDINGS. PRELIMINARY.

[Patron Link]

“It is clear that centrally mediated circadian rhythms play an important role in human health and our results provide initial information about how appropriate sunlight exposure to subcutaneous white adipose tissue (scWAT) might act as a peripheral circadian sensor that contributes to metabolic health. In contrast, a lack of sufficient bodily exposure to sunlight may contribute to long-term scWAT dysfunction and the current epidemics of obesity, diabetes and cardiovascular disease.”

WUUUUUT

Melanopsin is the blue light photon receptor in our eyes responsible for relaying sunlight to the SCN to entrain the central pacemaker. Well, a group of scientists accidentally discovered it fat cells:

Subcutaneous white adipose tissue express a light sensitive signaling pathway mediated via a melanopsin/TRPC channel axis (Ondrusova et al., 2017)

Figure “C” takes the cake. Electrophysiology studies show this receptor is highly sensitive to 465 nm blue/green, meaning it’s probably definitely melanopsin.

and guess what it does?

LIPOLYSIS — see Figure “E” above. Activation of melanopsin reduces the size of lipid droplets and lowers leptin. Interestingly, it also reduces adiponectin.

 

 

They also discovered this in mice, who are covered with fur and most of their melanopsin-containing scWAT is on their bellies which would never be exposed to the sun anyway. So….
