Science at its best - thank you Dr. Mason! You’ve obviously done your homework and have reported your findings in a very clear, well paced manner. Keep up the great work!

[@danschweri]

It's always a happy day when I discover a new presentation by Dr. Mason online - thank you so much!

[@rfender2493]

Thanks for everything you guys do. All the research and information . We appreciate it

[@aprilek6003]

excellent - thank you - i will be sharing with my athletic buddies - i for one feel amazing, tons of energy, strength, and have leaned out nicely. 3 years and counting

[@darkfieldcarnivore3928]

So well presented but still ignored by 99% of dietitions, influencers and athletes. Such a shame!

[@Freddieceps]

This presentation is so good! Thanks so much for the excellent work.

[@alexs5394]

totally anecdotal, but my results agree with this. i was honestly blown away at how long it took for my high intensity exercise potential to recover, but now it is higher than it ever has been!

[@gustavoazzo]

Again, thanks Dr Paul Mason. You are amazing!

[@holyhellal]

always great to watch a dr Paul video

[@jutto64]

Thank You Dr Mason :)

12-20 weeks to get to a good level of fat adaption. I was about 16 weeks, stinky acetone sweat suddenly disappeared and my cycling performance really took off. Pretty much exactly what DrMason states here. I reintroduced some more carbs, to stay metabolically flexible. I am still low carb overall. Doing a 4 hour bike race limiting carbs, but increasing electrolytes resulted in feeling great all the way to the end, no bonking . No sugar hangover after.

[@johnkollhoff]

What do you use for electrolyte replacement during training and performances?

[@defeqel6537]

I do wonder whether fasting could improve the rate of adaptation.

[@lloydhlavac6807]

I wish I had known about all this back when I was bike racing. It would have been interesting to experiment.

[@michaelpagan3914]

It takes time but it's worthwhile.

[@stephendudakov4565]

Excellent work.

[@vaughanc4919]

Fascinating talk

[@CrumbleLives]

Great video! I wonder if the VO2 max chart was based on a crossover study? I'm thinking that fitness and carnitine levels would play an important part in controlling CPT1 enzyme levels in the liver and downstream MCT creation.

[@maltheopia]

The CICO people think that the 'calories out' portion comes from some big magical block of energy from the shadow realm. They ignore how the 'calories out' portion of the equation can come from different parts of your body depending on how/what you eat or how your body has ways of altering the 'calories out' portion of that equation i.e. fatigue, body temperature, sleep changes, perspiration, metabolic slowdown, even mental changes. Nah, it's all the same to them. Once it's in your body, it all comes out the same way with no side-effects or differences in efficiency.

[@defeqel6537]

Similarly 'calories in', it's pretty well known that about 1/4th of the energy of protein is used to metabolize it. 400kcal protein is ~300kcal effective. edit: and there are other considerations as welll

[@motomatta1]

Excellent 👍

[@gstlynx]

Bravo.

[@225rip]

Dr Mason, can you comment on how HRV responds to Keto and fasting? I have seen some great peaks and some dips in the first month.

[@agianfelici7859]

[@megaswenson]

Worth the concentration it takes to compensate for having to subconsciously translate Australian pronunciations, while coping with distortions in the recording. The information here confirms what the more "pop" Keto docs are saying. Worth listening to several times, and making notes.

[@jillcat51]

Would love to see a debate between Dr Mason and the Carb Queen Louise Burke :-)

[@dtcdiscipulostotalmentecom9137]

Great info but sadly audio is less than desirable

[@davejonesjones6289]

It would be worth a look at American natives where well known to run huge distance on low carb mainly meat diet

[@nickyashby]

struggeling a bit with adaption, my running V02max has plummeted from 65 to 57 since going LCHF. i generally feel well but depite consistent running training I havent been able to raise my performance even a point in about 6 months..... Im a very experienced runner and have dropped and raised my fittness in cycles most years, just cant raise it again this year. inflamation down and strength and recovery good, just cant run fast for long anymore. any advice appreciated :)

[@double949]

Hi, please let us know how you're doing now. Is your speed, distance, and VO@max back to normal? Thank you for sharing!

[@monicasterki565]

[@jamescokl3]

How long it takes for fat adaptions

[@K_F_fox]

I hope Ken and Sarah (17:21) still get along with each other at family gatherings.

[@lpdulley]

How does a Ketogenic Diet affect resistance training and performance? How can one be in a Ketogenic, build muscle and avoid catabolism?

[@TB1M1]

It's a disaster the best diet bar none is high complex carb. This diet isn't low fat either you can eat up to 25% fat. But you cannot eat 43%cal fat like the standard american diet. kzbin.info/www/bejne/i6uZhJJsfKecsK8

[@Biggiiful]

@@TB1M1 not true. Plenty of people are gaining and maintaining muscle on keto.

[@ninjableu9134]

Awesome, was asking myself the same questions =)

[@wwsoft]

Can we fix the audio? I like Pual Mason's material but the audio quality is downright distracting.

[@ellenorbjornsdottir1166]

He didn't give this to a conference hall.

[@danielrodgers3002]

Can someone point me to any professional endurance athletes that FULLY embrace a low carb diet?

[@Ariel-oo1nc]

Zach bitter - was a volunteer subject in the FASTER Study looking at high vs low carb performance. Does the Human Performance Outliers podcast. Mark bell - Powerlifter currently on a Carnivore Diet. Has his own podcast, Mark Bell's Power Project.

[@SamuraiBatgirl]

Tim Olsen and Chris Froome.

[@danielrodgers3002]

@Inflammation Gains No, That is Not correct. Zack admitted that he occasionally goes low carb during some periods of training. What he does is much more like carb loading in my opinion. See his latest Joe Rogan interview.

[@Dibbler613]

Pro Triathletes: Andi Böcherer, Tim van Berkel, Jan van Berkel, Scott Bayvel, Pete Jacobs. Not a Pro but fastest Age Group Athlet in the Ironman Hawaii 2018 was Dan Plews. Amanda Stevens in her last pro year.

[@kateaye3506]

Paula Fraser from Zimbabwe(?). Won Ironman several times.

[@TimL1980]

Just quickly calculated that I would be able to run a marathon on fat alone if fat oxidation stays at 1.6g/min.... that is probably why I never met the "man with the hammer" after dropping pasta and bread. Nice to know!

[@HakuCell]

how does the brain/body get glucose on a ketogenic diet? even more so in athletes. do cortisol levels need to go up in order to steal glucose from muscles?

[@ronhenry0]

1) Your brain can use ketone bodies for energy; your body can use fat & ketone bodies for energy. This reduces the requirement for glucose. 2) Dr Mason notes that glycogen levels are not depleted in fat adapted athletes, and they recover glycogen faster after exercise, without eating carbs. 3) There is a path from fat -> acetyl CoA -> acetoacetate - acetone -> acetol -> (methylglyoxal or 1,2-propanediol) -> pyruvate -> glucose that can supply 10-12% of required glucose in fat adapted people. See: chrismasterjohnphd.com/blog/2012/01/07/we-really-can-make-glucose-from-fatty for references. 4) and yes, you can make glucose from protein, so low carbers need to eat sufficient protein.

[@persophone4554]

Firstly, you don't need enormous amounts of glucose in the brain. The "ketones" are able to provide most (not all) of the energy used by the brain. Glucose can be formed by many mechanisms: Firstly, each time you "burn" fats from a triglyceride, you released glycerol which is converted to glucose. Secondly, essential glucose can be obtained by gluconeogenesis from certain amino acids such as glycine and several others. You can also make glucose from several other pathways - including lactic acid from extreme sport stress!

[@TheJohnMak]

Why do medical doctors say “my name is Doctor xxxxx”. There name is not Doctor anything. Doctor is their title. They can say, “hi, I am Doctor xxxx”

[@thatsjohn3938]

Well done talk. Fantastic information. Dr. Mason, John Leonard here from Toronto, Canada . I sent you a private message via Facebook. In regards to a keto and anaerobic threshold one year film documentary that I am doing. I would like to. Keep in touch with you. As I said, you'll find my Facebook message to you. In your private box there. Have a fantastic day and keep up the great awesome work.

[@loganwolv3393]

So, in conclusion carbs are killing your gains.

[@RyanOstarineGarcia]

low carb may work for cardio exercise but not weight lifting. I cant even lift my max or go to complete failure if I dont eat carbs. I tried keto for 2 months and it was shit for my weight lifting and I was fat adapted before I started since I did 3 day fast once a month for 3 or 5 days last year. My body burns up fat quick cause of all my muscle so I need carbs

[@RyanOstarineGarcia]

i also did a 14 day fast once

[@pobsarducttapeproducts8763]

19:36 this is untrue. We actually know exactly how much less calcium is absorbed as protein intake increases.
