keto deplet-o bifido?

say it ain’t so

[Patron link]

Ketogenic diets alter the gut microbiome resulting in decreased intestinal TH17 cells (Ang et al., 2020)

To be honest, it wasn’t the Th17 cells that caught my attention.

It was this:

and then this ?

A huge drop in actinobacteria and more specifically, our beloved bifidobacteria!

This is humans on a well-formulated ketogenic diet.

What went wrong?

keto: which comes first, reduced body weight or liver fat?

pretty strongly recommended pre-reading: “independent of body weight” means independent of body weight which discusses THIS study (Luukkonen et al., 2020)

[Patron link]

In brief, they tested a 6-day ketogenic diet on liver fat. Two time points, before and after. You can’t detect a trend with two time points; it’s literally a straight time.

They really wanted to see if keto could reduce liver fat independent of weight loss… I mean, we know weight loss does it, so that’d confound the test of keto per se.

they lost weight :/

And with only two time points, we can’t even see if one thing (body weight or liver fat) started to decline before the other. Despite this, the authors stuck to their guns and implied keto was the main driver.

We have another study on this!

plant-based LF vs animal-based keto. Does this guy ever sleep?

getting a lot of emails about this study; here’s my 30000-foot view. I’ll update if the final version differs from the pre-print in any meaningful way.

[Patron link]

Nutri-Twitter has a love/hate relationship with Dr. Kevin Hall’s research studies. Even I’ve been critical of some in the past. But he’s doing the work. Gotta be one of the most productive researchers in the field, attacking the diet wars from a variety of angles.

Small sample size and short duration, but that’s the price you pay for an extremely well-designed and controlled study.

Main endpoint was ad lib food intake. Many people have criticized the short duration: 1) two weeks to study ad lib food intake. Many of those same people will champion SINGLE MEAL studies, effects of macronutrient-specific meals on food intake during subsequent meals. In that light, 2 weeks is above and beyond the status quo.

2) insulin, appetite, and ad lib food intake PLEASE DON’T SHOOT THE MESSENGER

the most expensive spice

SAFFRON

[Patron link]

around $200/ounce or $7.50/gram

Gold is around $1800/ounce and a #Bitcoin costs $8000. But this is about saffron.

It is a very versatile spice that has been tested in a wide variety of clinical conditions.

Most widely studied for age-related macular degeneration. And it works. That’s probably because the active ingredient, crocetin, is very similar to the carotenoids lutein and zeaxanthin which have also been shown to be very protective of eyesight.

Reduced snacking frequency and increased satiety, depression and anxiety, mild cognitive impairment, etc., etc. I encourage you to read about it!

The proposed mechanisms of action are quite interesting.

Chocolate for breakfast and avoiding late-evening meals sustains fat burning :)

wait, WUT? lol OK, the chocolate thing came from a study in rats (albeit a pretty interesting study).

[Patron link]

First, the human study:

Eating breakfast and avoiding late-evening snacking sustains lipid oxidation (Kelly et al., 2020)

They called it a “snack,” but really it was identical/isocaloric to the breakfast meal. We’ll call it “dinner (D),” and it was shifted about 4.5 hours later than in the breakfast group (B).

They found that a late dinner gimped fat oxidation over night. Carb oxidation was higher, kinda like when you exercise O_o

Why are you burning more carbs when you sleep? …and burning less during the day. Maybe this contributes to the consistent blood glucose-lowering effects of #eTRF

some mechanisms and effects of nutritional ketosis

Ketogenic diets and protective mechanisms in epilepsy, metabolic disorders, cancer, neuronal loss, and muscle and nerve degeneration (Li et al., 2019)

[Patron link]

New review out, that got a lot of stuff right!

For example, it’s useful to talk about starchy/net carbs in terms of % of calories because for people with vastly differing total daily energy intake, the actual grams will differ considerably. Also, if you want to know if your diet is ketogenic, there’s a neat little trick.

Topics covered: biochemistry of ketogenic diet-mediated energy generation, general health, type 2 diabetes, weight loss, fatty liver, neurodegeneration, muscle biology, and more!

quantum biology – it’s real

First things first: new drug on the market. You know how anti-histamines (eg, diphenhydramine) are sedative? Histamine in the brain is ‘alerting’ – in the gut it’s involved in gastric secretions and in the immune system it makes you itchy.

[Patron link]

There’s a new anti-anti-histamine that appears to be effective for treating excessive daytime sleepiness in people with narcolepsy. Pitolisant.

Pitolisant is apparently highly selective for the brain H3 histamine receptor so it doesn’t mess with your guy or make you all itchy.

No biohacks here, just learned about this compound and thought it was a cool concept and may be very helpful for some people.

I’ve been watching lectures by Sean Carroll and Philip Ball lately. If you have any interest in physics, highly recommended! Quantum biology…

Insulin Hypersecretion

The relationship between hyperinsulinemia and insulin resistance is a bit murky (Nolan and Prentki, 2019). Dr Corkey gave a good presentation on this, which Tl;dr: goes something like this — stuff in the environment, your food, etc., causes insulin hypersecretion. Not regular carb-induced insulin secretion, and not enough to cause hypoglycemia… just enough to cause insulin resistance.

[Patron link]

I also recommend checking out some of Brownlee’s work on the microvascular and macrovascular consequences of hyperglycemia — it seems complementary to this (eg, Giacco and Brownlee, 2010; Shah and Brownlee, 2016). A lot has changed in the last decade, but there are still a lot of relevant points, or at least things to be aware of.

The Nolan and Prentki review is good – the basis is that there is no grand unifying theory underlying metabolic syndrome agreed upon by clinicians and scientists. I concur. Also, there probably isn’t one single mechanism because there are many different phenotypes/manifestations.

Definition: when I say beta cell failure in the context of T2D, I don’t mean dead failing beta cells, I mean beta cells that are trucking out more insulin than ever… but it’s not enough to keep glucose under control (due to insulin resistance). Now that that’s out of the way…

#eTRF OMAD (Singh et al., 2019)

I’m not a huge fan of OMAD (one-meal-a-day) — if it works for you, cool, but it’s not where I’d start. Harder to meet protein requirements, metabolic mayhem refeeds, disrupted sleep quality, etc. But it helps some people control calorie intake (I understand, it can be difficult to overeat all of your daily calories in one sitting… very full belly!)

[Patron link]

Franz Halberg, one of the fathers of chronobiology, did some pioneering studies on AM/PM meal timing.

He and his contemporaries and students (eg, Jacobs & Hirsch) were among the first to study OMAD breakfast vs. dinner.

Tl;dr: they took a group of people and gave them all of their food in one sitting – breakfast or dinner. The breakfast group lost weight. Upon reviewing the diets, it turns out the breakfast group was eating less. So they followed-up…

can you guess what happened?

Circadian rhythms – exercise & meal timing

Two studies on exercise and a review on meal timing.

[Patron link]

Single-session exercise studies show better performance in the afternoon, although this is trainable – consistent AM training improves performance in the AM and PM whereas consistent PM training does not improve AM performance.

Chronotype effects? Circadian rhythms?

But that’s neither here nor there. Exercise is better than no exercise, and if you have the luxury to choose, evidence favors AM.

Comparison between the effect of 6 weeks of morning or evening aerobic exercise on appetite and anthropometric indices: a randomized controlled trial (Alizadeh et al., 2017).

Good study – main outcomes were body weight, appetite, and ad lib food intake.

Exercise doesn’t burn a whole lot of calories but it’s very good for you. A goal of this study was to see if exercise timing influenced appetite and ad lib food intake, which have a greater role in regulating body composition.

The exercise intervention was modest, ~30 minutes of cardio in the morning or afternoon. Main findings: significantly greater reduction in body weight, BMI, waist circumference, abdominal circumference, and abdominal skin fold thickness in the morning exercise group.

The morning group also spontaneously ate less throughout the day despite no difference in appetite/hunger scores or exercise intensity between the groups. Boom.

Does AM exercise and skewing kcals earlier in the day work for you? Will you try it?
