Media, Schmedia

A study that claimed low-carb dieting was terrible for heart health has been retracted due to concerns with data integrity and conflict of interest.

Hustle porn—the fetishization of extremely long working hours—is a grave danger, according to Reddit’s founder.

Reader Question of the Week

Regarding fasted workouts, Chim Richalds asked:

What about for someone who isn’t fat adapted? I take a fairly liberal primal approach which is high in all 3 macros, am I likely to still see the benefits?

Yes, you will see the benefits.

Fasted workouts (and fasts in general) are going to be more difficult to initiate for the average person eating higher-carb. It may be hard to decide to train in a fasted state and actually stick with it. But I’d argue they might even be more important, the more carbs you typically eat.

Fasted workouts supercharge the fat-burner within all of us. I’ve always said that everyone should spend time in a ketogenic state from time to time, even if they’re eating a high carb diet. The best way for a high-carb dieter to reach ketosis is through the occasional (or regular) fasted workout.

Fat oxidation goes up.

Glycogen drops (from utilization). You can’t help but turn to fat for energy.

Mitochondrial function improves. You may even start building new mitochondria that are better at burning fat.

Metabolic flexibility increases. This is the phenomenon of that athlete everyone knows who can eat whatever and still look and feel great. High enough activity levels bestow a superhuman metabolic furnace.

  1. Mark, thanks for the reminder on Fasted Workouts. Since I normally lift or do HIIT after work and have had lunch, the options have been limited. I tried on the weekend twice after 16 hour fast and noticed no drop in strength or energy levels nor hungry afterward.

    Been 3 years Primal now and seeet spot for me seems to be IF during week, eating window from 12:00 noon to 6:00 PM. Gronk breakfasts on the weekend and 3-4 gym sessions a week.

    Pretty bizarre being in best shape and body composition at 58, but not complaining. Keep spreading the word Mark! The movement is spreading up in Canada, where change is slow….

  2. “Early humans bred with other hominid groups to gain cold tolerance.”
    Maybe it was a side effect: a fortunate legacy.

    1. I think that “Early humans bred with other hominid groups to gain cold tolerance.” was a shortcut way
      of explaining the process. Nature caused mating and the results fell out. But naturalists use this figure of speech all over the place as spelling out the process is just too long.

  3. Shanahan sounds like an old Irish word for narrator. I can’t remember exactly.
    I read (check it out, Sisson!) Leon Ulris’ Trinity. Well, if you are so inclined at you leisure.

  4. Brilliant story about ecological amnesia. It’s amost impossible to picture the skies filled with passenger pigeons and 100 million bison roaming the grasslands.
    Guess we will just lurch forward into the future wearing VR headsets with all the beauty we have lost, and will continue to lose.

  5. I’ve been seeing vegan demands for their dietary choice to be forced into everybody , for years.

    As a meat producer, I am aware just how ignorant, poorly researched or downright dishonest, most of their arguments are…. but that does not seem to stop them.

    Did deep enough, and you find underneath it a moralistic fervour driven by the need to define everything that they don’t agree with as “evil”. Their ultimate benefit is that it allows them to see themselves as “good”, because they don’t actually make any sacrifices.

    1. Agree that their dietary choices should not be forced onto everyone and we need to push back against that effort, as well as challenge the bad science. However, I think we need to draw the line at psychoanalyzing motives and sterotyping. Most vegans I know are motivated for ethical reasons and that needs to be respected. We meat eaters have to accept the fact that living creatures are being slaughtered for our consumption and for some people that presents a moral dilemma.

      1. It’s not so much “psychoanalysis “ as being honest about the implications of vegan activist claims.

        Of course living things die. The dishonest pretence is that things don’t die in order for vegans to eat, too. Grain and vegetable crops require complete destruction of the native ecosystem in the fields where they are grown, in order to achieve efficient production. Habitat destruction is one of the most significant causes of wildlife decline in the world today.Every crop that vegans eat is preferred food for other species. Without killing, we would not have the cheap, reliable food that is now available.

        I have zero problems with people making their own dietary choices. I STRONGLY object to people trying to force their choices onto me and mine by tax, legislation, false environmental arguments or moral bullying.

        Vegans have as much responsibility for death as anyone else. They merely pay farmers like me to do their killing for them.

  6. I like getting the weekend link love on Sundays a lot more. Just sayin….

  7. I have enough trouble affording meat for my 2 toddlers as it is (because I only buy them good quality meats). Maybe the meat tax (if it happens) won’t apply to foodstamps since there is no tax currently when using foodstamps… And I suppose that would just be more incentive for people to buy their meat locally since there’s no tax when buying directly from farmers! Might be a good thing in that case? Though conventional meat with a meat tax *might* still be cheaper than local pastured meat, so this might only apply to people who already buy pastured meats from grocery stores.
    Either way it may actually do more good than harm. If people buy less conventional meat because of a meat tax, that’s less support to factory farms and I’m all for that.
