I have always found the ketogenic way of life very relaxing.

I’m a 58, almost 59 year old cyclist who has been practicing a low carb/high fat diet for four weeks. This winter I’ve trained mostly on an indoor trainer keeping a low to moderate level of efforts — and have done fine using fat as fuel. The weather here in Michigan broke for a bit so I recently rode outdoors on a very demanding, hilly route. During this outdoor ride the second large hill I encountered, where my heart rate elevated over 170, I immediately bonked and had to walk, (keep in mind years prior I’ve logged 4500 - 5000 miles per year on a bike and never walked due to exhaustion). I new I had 18 more miles to go to complete this particular ride. The fascinating thing was every hill I would encounter, (and there were many) I walked a little less and by the time I had finished the 22 mile route I was able to ride up each punchy hill, (slowly, but able to ride), It was as if I could actually see/feel my body adapting and using fat as fuel at increasing intensities. The bonk actually went backwards during this ride — hit the wall at the beginning yet performance slightly improved as the miles went by. It was something I had never experienced before.
I have a lot of training to do to get my performance/speed back up ... but at least I know it’s possible. Your one chart that showed carb depletion after intense exercise in athletes, (different levels of fat adapted athletes) reenforced my thoughts on this. Great information you’ve provided.

Thank you for posting this presentation.... immeasurable value gain here

[cleanwithHO]

Thank you for posting presentations like this one, so that the information is more widely accessible to the public.

Keto is the best thing I’ve ever done for myself.

Wow, Even Robert Luistig is here! Maybe we have "Ketosis, the sweet truth". Congratulations for the work

[TheMpamMpam]

Great stuff for health overall but it seems to be geared to marathon-endurance athletes, what about power lifting or similar high intensity sports?

[markshfr]

His answer to that question couldn't have been more dead-on 😉

35 days in after I changed life style 180 degrees. carnivore diet, eat once a day and done two 48 hour fast. Feel grat and all my Undefined health issues is almost gone...But I am worried on my Ketone levels.... Ketones after 14 days started to show 4-5 mmol/L but sometimes spike to 7-8 and once to 8.7 mmol/L. my understanding is that unless Glucose is high this is ok ? My Glucose was 3.4 mmol/L when Ketones was 8.7 mmol/L.

Prof. Volek at 38:05 min - If i'm using the TNT Diet how this will work?

[GaryvanderMerwe]

Question from Dr. Lustig at 45:05 very interesting!

[jselectronics]

I've been carnivore two years. I can have a cheeseburger and still measure 0.8 ketones later that evening, even though my blood sugar is 115.

[christophernieves]

I don’t agree with his evolutionary take on ketosis. Not every low carb tribe or group goes into ketosis. The Inuit and Maasai have evolved to resist ketosis as an adaption to starvation. So while I can certainly see applications for a low carb or Leto diet I believe his evolutionary perspective is off.

more data guys you can talk about all this stuff but if you dont have data you are wasting your time.

[brutuscallaway]

The blushing account indisputably taste because notify epidemiologically gaze than a false familiar famous sound. short, thoughtful reading

[backfru]

I love how no ketogenic studies have actually shown a performance BENEFIT.
"keto athletes burn more fat!"
As if there's a prize for who burnt the most fat during the race.
No, the person who WINS the race eats a LOT of carbs.


If you want proper data on how proper athletes eat to perform, look up Louise Burke, Trent Stellingwerff, and others in the area.

Go for vegan keto .. eat low glycemic food ..
