A real professional who incorporates Unbiased analysis. A rare find on YouTube..

I did a strict vegan diet that included no added oil or nuts or other higher fat plants for 8 months. I lost nearly 20 pounds, going from the high end of normal bmi to the low end. My purpose was to bring down my cholesterol to get my doctors off my back regarding statins. My total cholesterol went down to about 200 and my ldl went down to 116 in four months. The negative consequences were that my menstruation stopped and all of my tissues, skin, eyes, etc. became very dry. I went on vacation about 8 months in and added back in olive oil, nuts, avocado to make things easier and my menstruation returned. After adding in the healthy plant fats, my cholesterol only increased two points and my ldl went down further to 106.

I don't have much faith in nutrition wash-out trials like this, because I think one week isn't enough time to really get back to baseline. Also, I don't think 4 weeks is really long enough to see the real, long-term effects of dietary patterns.

[PlantChompers]

What an awesome analysis! 👏 So much insight in so little time.

I just discovered your channel and am watching all your videos I love how you explain things without being dogmatic or judgemental

[edl]

In my opinion, me non-professional, I think the study was flawed as both groups should have maintained an equivalent caloric intake. Additionally, the washout period was too short. - Thanks for the review.

It feels so refreshing to listen to scientific facts/hypotheses being presented with the support of primary literature. So many pseudo-scientific channels out there claim that "a great deal of evidence supports the idea that [insert of favorite subject here]" without actually showing you the evidence. Gil does not expect you to trust him blindly. He actually shows the publications where he find his information, and lets your draw your own conclusions. This channel is about as scientific as it gets, and I love it for that. Don't change anything. Congratulations, and thank-you for the great work!

im confused why they didnt equate calories, isnt that an important and potentially confounding variable with something like ldl?

[elberthiggins]

To me the big conclusion is that cholesterol did not go UP on a high olive oil diet. With all respect to Drs Esselton, Furhman, etc I'll continue to put OO on my vegetables.

[SundanceKey-kouy]

The big question remaining is, What about all the other benefits of olive oil? Like its anti-inflammatory effects?

[nitrostudy]

Dumb question?

Given the groups had high risk of developing atherosclerosis, it is likely their regular diets were far removed from vegetarian status. Therefore, an abrupt shift to the vegetarian diet would have caused substantial changes in gut microfibre composition. Perhaps microflora-associated metabolic changes contributed to rapid responses in the 1st 4 weeks.

However, with only a week of their regular diet (some may have eaten partially healthy if they saw weight improvements?), in the washout, gut microflira composition would have less time to revert. As such, in the second phase, gut microflora composition change was less extensive, and therefore had less effect on starting LDL-C reduction (etc).

Thank you for finding a way to talk to the first author

Small sample size. The small amount of calories is (1300) probably the biggest variable. Not the change in evoo.

[SladkaPritomnost]

Low oil group was very low in calories, they mainly dropped weight this might play a big role in cholesterol levels.

[kygo]

Couldn't the big drop for the first group just be from the low calories and they lost more weight over the 4 weeks, and nothing to do with the olive oil?

Strange they didn't make both groups eat the same number of calories...

[gruber]

Thanks, you're a very good teacher.

[wiadroman]

4 weeks on 1300 kcal / day? Self reported? Gimme a break.

[firstlast]

My Cholesterol went up dramatically and the only thing different I did was consuming more organic coconut oil and olive oil. Hopefully the study used real olive oil since the market is saturated with fake oils cut with seed oils

[pkeiths]

Always worried when I watch your videos, as they often shatter my beliefs what is a healthy diet 😢.

[Lambda_Ovine]

well, if more evidence and future studies support this, I for sure won't stop cooking with oil (not 4 tbsp daily tho, that's a lot), I already gave up a bunch of stuff I used to love, giving up cooking with oil would make my food so insipid as to make it not worth it keeping my diet
