Diet Dog Fight: Keto Vs Vegan

Rohin Francis, MBB: As regular viewers know, whilst I'm very interested in diet, I don't really cover it very often on the channel for two reasons. First, there is already so much on YouTube about diet. I try not to go over previously-covered territory, and second, I just can't be bothered with all the tribalism and arguments. Even when I post an entirely innocent, neutral question without any commentary on Twitter, people feel mandated to reply about why their camp is better, why I know absolutely nothing, and it gets pretty boring. A few weeks ago, I tucked a paper into my bookmarks to read later. When I finally got time last weekend on nights and read it, I actually thought it was quite a good trial and support for ketosis worth sharing with you, which is why I'm making this video and why I've escaped to this beautiful, scenic location to get away from my kids.


Here is a deliberately short little discussion of what can be summarized support for ketosis this trial as basically keto versus plant-based and it was published in Nature Medicine, a good journal, last month. My name is Rohin. I'm a cardiologist in the U.K. I have no diet books or diet plans to sell you. Now, I have said before that nutrition research is sullied by a lot of garbage. Untested theories, retrospective questionnaire-based studies that are pointless and inaccurate. That's because it's profoundly impractical to lock people up in a room and monitor everything they eat and do. Well, that's exactly what they did over at the NIH, the National Institutes for Health, in the U.S. They convinced 21 people to spend a month locked up with all their food provided. Now, this was done pre-lockdown, but you know, they should probably start recruiting for their next trial now because that doesn't really sound any different to the life most people have been living for the last 12 years, except with free food, and actually pretty nice food, so I think they'd probably get a lot more volunteers now.


The participants were not told what the trial was about. They were just instructed to do their normal things, not try to lose weight or do anything special. They were actually given loose-fitting sort of scrubs to wear and just eat as much as they want, and that's ad libitum that you see in the title. It's a fancy way of saying, basically, "Eat as much as you like." The catch was that half received a keto-style, low-carb, animal-based diet and half received a plant-based, high-carb, low-fat diet, and then after two weeks, they switched. Now, the first thing that I'm sure you'll say is that this is a month in total. It's too short. Of course, this is a short trial, but this comes down to study design. They're not looking for prevention of stroke or heart attack risk. This wasn't designed to do that. It wasn't powered to do that. You need thousands of people over many years to establish that kind of thing and you obviously can't lock people in a room to do that for a long period of time.


The prime outcome for this study was to measure energy and macronutrient intake with a bunch of secondary endpoints like measuring insulin, blood glucose, and things like that. So what was the thinking behind this? The central ethos to low-carb diets, which is the carbohydrate-insulin model of obesity, was kind of the inspiration for this. We know that insulin -- and we've known this for decades -- has a very important role in how fat is laid down and how it's used up. We know that insulin levels go up when you eat more carbohydrates. So carbohydrates cause insulin release and the thinking is that insulin causes fat storage, so the level of circulating fuels in your blood decreases and this tells your body to eat more and to deposit fat and Supraketo Keto use less energy. This is the idea behind low-carb diets, which remember, have been around for a long time, since the 70s or so with Atkins.


Also, it's important to remember that this theory was counterintuitive to the commonly-held theory, which still a lot of people believe now, that it is just purely about total calories in and calories out, and it doesn't really matter what the constituents are. The carbohydrate-insulin model challenged that simplistic belief. I do apologize for the wind. The study in hand randomized participants to either 14 days low-carb or 14 days low-fat and then switched them over. They were all non-diabetic participants. They had an average age of around 30 and an average BMI of about 28, so they were overweight. The low-carb food was consistent with keto meals. It was animal-based with non-starchy vegetables, i.e., things like greens, and the low-fat one was consistent with a plant-based vegan healthy diet, again, with non-starchy vegetables alongside things like sweet potato and so forth. As expected, the insulin and blood glucose levels were significantly higher in the plant-based group versus the keto group and blood ketones were higher in the keto group.
