Cooked meat provides more energy than raw - Harvard Study

Insight?  Criticism?  Questions?  First obvious problem is that this study was done on mice.

I always operated under the assumption that cooked meat would provide less energy than raw meat.

It's very annoying that there aren't more studies down with human subjects instead of mice! One mammal =/= another mammal!

I've always assumed that meat is meat: the calories are the same. Cooking it may improve the bioavailablity of the nutrients of the food are but, naturally, cooking TOO much will reduce the nutrition of the food you're eating. That's just my assumption, I've never really looked into it specifically.

I've read here and there that cooking meat increases digestibility. So it could deliver more calories.
The answer to your question is 'eat more fat'.

Stop counting calories. If you are eating Paleo, there is usually no need.

If you are having weight loss issues, it'd be a good idea to start posting a detailed food journal, then everyone can help.

'Anecdotal Evidence' is an oxymoron.

I think using a mouse study to try to prove that humans are adapted to cooked foods is a stretch.

I don't have any argument with the factual result.  Cooking involves adding energy to the food.  I'm not at all surprised if that means our digestive systems don't have to use as much energy to finish digesting it, thus resulting in greater net energy extraction.  I'd be surprised if it were more than a few percent.

I doubt it has any significant implications for how to eat.  Food is more than just calories.

I will present 3 examples:

----------

My 10 year old son (not that one in my avatar) is recovering from grave illness... very very visual debilitating itchy almost full body eczema on the outside (but inside it is wrecked large intestine, small intestines, super leaky gut, with candida, yeast, fungus)

As part of his recovery he needs to be on a RAW Paleo Diet.

And each time he and his mom tried to "cheat":
- eating cooked fat (butter - even if grass fed)
- eating cooked fish
- eating cooked vegetables
- eating cooked rice

His "cheat" would result in immediate regression of his illness. He wakes up and his skin and itch tells him... ha! you cheated! (yourself)

------------

Just 2 weeks before my son got sick I saved my in-laws' driver (50 years old) from deathly pneumonia.  I also put him on a raw paleo diet for 10 days.  In his case a lot of raw fatty beef and raw fish and raw clams and raw oysters.

------------

My then 4 year old daughter had very painful tooth decay in a molar.  We went to the neighborhood dentist and he said it was too inflamed to work on it.  He suggested 3 days of antibiotics and the pain will go away in 3 days.

I had a better idea.  I put my 4 year old daughter on zero carb / raw meat raw fat only + water for 3 days.  I gave raw beef, raw marrow, raw clams and in only 2 (two) days her pain and inflammation in her tooth decay went away.

------------

So everything is IFFY on an individual level, genetics, current state of health.

For the very ill, cooked meat will most likely suck.

The very ill must bet on raw meat, raw fat to recover... back to nature baby.

What does healing the very ill with raw meat tell us?

Healing "Energy" is a valid form of "Energy".

As far as the human body's energy expenditure on DIGESTING cooked meat is far longer and far greater... than raw meat.  Because raw meats freshly killed, never been stored in "plastic" or aired properly or aged properly have their own beneficial probiotic bacteria and enzymes that help the meat digest themselves in 1 hour's time compared to 3 to 4 hours time for cooked meat.

You can experiment yourself and see that you need MORE sleep regularly eating cooked meat, while you need markedly LESS sleep when regularly eating raw meat.

So eating cooked meat all the time, humans suffer a penalty with DIGESTION.

And there is also the penalty of DETOXIFICATION which is another Energy EXPENSE.  Because the body has to sort through and remove toxic stuff.

-----------

On my 3rd or 4th month of Raw Paleo Diet (raw meat + raw fruit + some raw vegs) I decided to try out Cooked Meat Paleo diet (cooked meat + raw fruit + some raw vegs)... and to be fair, zero condiments, just to see if I could make it work and make me seem more "normal".  I blogged about this as I had to stop my cooked meat paleo diet after 30 days as I was feeling progressively really bad by day 30 I had to stop. 

So I went back to raw meat paleo diet. 

Just my experience, a sample of 1.

-----------
Cooking for me is a great SURVIVAL tool and when times got tough in "the garden of Eden", then the smart people learned to cook to eat consume more of the lessening animal, to cook vegetation or root crops or animals that would otherwise have been INEDIBLE.

Of course the tribes who knew how to cook and store food grew and conquered the uneducated barbarians.

I like very rare beef (blue) but I don't like cold food. I am pretty sure I could not eat raw chicken or pork.

How could I try raw but warm? Is it possible? (and apart from killing it and eating it before it gets cold)




I love my computer, all my friends live in it.

I simply can not wrap my head around eating raw fish/pork/chicken.  I like a medium-rare steak, but that's the extent of it.  I have a hard time with the bacteria issue.  I know that people say that the bacteria in the meat is safe for humans as we have been ingesting it for millions of years, but, just to play devil's advocate here, wouldn't it be safe to say that the bacteria in animals has evolved just like all of the antibiotic resistant strains that hospitals are dealing with on a regular basis.  I would find it hard to believe that the bacteria in a chicken today and a chicken 10,000 years ago are the same.  And even if you eat only organic, pastured meat, the quality of the food source for the animal has changed.  There is nothing about today's life that mimics the Paleolithic.  I guess that's why I have a hard time buying into the "raw".  I could be way off base, it's just a thought...

cooking plants, too.

Cooked meat is easier to digest and provides more net calories per gram than raw, I believe there are some reasonably good studies that back this up.

Face it, cooked meat tastes better than raw.  And what are we designed to think tastes good?  The best sources of nutrients, which is why meat (or honey) tastes better than spinach for example...
Sugar addiction kills more people than all other kinds of drugs combined

If your food needs a prefix, it's not paleo!
