Hey guys, I’m Siobhan a second-year medical resident Today we’re tackling a super controversial issue and that’s The Keto Diet The question is – is the keto diet actually making you live longer? or could it be actually killing you faster? The keto diet is a very low carbohydrate diet. About 75% of calories come from fat 20% from protein and only 5% from carbs It’s become one of the most popular diets online and it’s been praised for weight loss, heart health, diabetes management and some even believe it fights cancer. But others think it’s probably just a fad diet and it’s just gonna come and go. Just this week, there was a groundbreaking article from The Lancet which totally changed the conversation It’s an article that looked at how much carbohydrates people are eating and if that affected life expectancy. By the end of this video you should be able to make an educated decision about what you want to do with your diet And then I’m gonna *urge* you to share this with people you care about because this could actually affect how long they live. *violin intro plays* So those of you who’ve been following my journey in the hospital at the new doctor know that about six weeks ago I started the keto diet. and the reason I did that is because Overnight I find they’re just so many chips and snacks and candy and … I- This whole year I just feel like I have strayed from my normal habits and so I kind of just needed like a reset and I figured that keto would do that. And it did. like I lost a couple of pounds I put on last year and I haven’t been having sugar cravings It was great. So this week when I was flipping through my computer I saw this article And I figured it was gonna tell me that the lower the carbs you eat the longer you live But that’s not exactly what it says. So the study started about thirty years ago, when they recruited a whole bunch of adults from four different communities in the US They recruited about 15,000 adults and then had them do surveys and they kept track of their health and they tracked them over about 30 years. *okay, that’s deep* So let’s pretend these skittles represent the people in the study First let’s divide them into the amount of carbs they eat in a day. The yellow ones the low-carb group. And so these people about less than 40% of their calories from carbs. The green ones of the moderate carb group. So these guys bought about half of the calories from carbs. And the red ones are the high carb group where they got over 70% of their calories from carbs. Of course this is a simplified model and in the study they worked with really fancy statistical models to get lots of accurate information. So looking at mortality within these groups. It turned out the low-carb (yellow) group and the high-carb (red) group actually died faster than that middle green group. So it looked like Goldilocks and the three bears. The middle 50% carb group actually lived the longest. And you can see that it has this U-shape, and we actually call that a U-shaped relationship. They’re estimating that in this in the low-carb group and the medium-carb group, That was almost a four-year difference in their life expectancy. That’s like high school. That’s university. That’s so many life experiences That’s huge. I mean, we can’t ignore that. Definitely not what I expected. Definitely a huge shock to hear. Question 2* So then the next logical question is if you have lower carbs you’re eating more fats and proteins Does it matter what types of fats and proteins you’re actually eating? So they went back to the database and they looked at all the people and they wanted to see the group that eats mostly animal products. So they’re eating meats and cheese, lamb pork, beef, chicken all of that compared to the people who are eating plant-based proteins and fats. So they’re eating nuts and peanut butters and seeds and they’re having lots of vegetables. And unfortunately all those meat lovers out there, it was very clear that people eating plant-based proteins and fats were living longer than those who ate the animal proteins and fats. And that’s tough for me. I actually really love a good steak. *pleasure* Ooo boiii
