[0:00] Brian Johnson spends millions every year [0:02] on his diet and program to delay aging [0:06] and death. I'm going to show you how to [0:08] do it for free. Brian Johnson is the [0:10] eccentric millionaire creator of Don't [0:13] Die, a program aimed at slowing down or [0:17] even stopping the aging process. A major [0:20] part of the program is a carefully [0:22] designed diet. But when you strip it [0:24] down and you take away all the flash, [0:27] the most powerful points of his diet are [0:30] not the expensive parts. They're not [0:31] some secret for millionaires that is [0:33] beyond your grasp. They're things you [0:35] can easily replicate in the comfort of [0:37] your own home for no extra cost. In [0:40] fact, if you follow what I'm about to [0:42] share with you, you might even save [0:44] money. I received my PhD for research on [0:47] aging and nutrition. And I've put [0:49] everything I've learned over the years [0:51] into designing my own diet to maximize [0:54] health and delay death. And going over [0:57] Brian Johnson's diet surprised me [1:00] honestly because he gets a lot of things [1:02] right. In fact, I think his approach [1:06] beats a lot of popular influencers out [1:08] there, including some that are doctors [1:11] and scientists. But there's also a [1:12] number of things about Brian Johnson's [1:15] diet that are extremely controversial [1:18] and that might not even be a good idea. [1:20] So throughout the video, I want to focus [1:22] on this question. When we remove all the [1:25] branding and all the hype, which parts [1:27] of his diet will actually deliver [1:30] results for you, and how can you [1:33] implement them as easily and as cheap as [1:36] possible, and which other parts you [1:38] don't need to waste time and money on? [1:40] If you want more evidence-based [1:42] breakdowns like this with no sponsors [1:44] and no sales, subscribe. According to [1:47] his website, Brian Johnson eats about [1:50] 2,200 calories a day, a little over [1:53] that, which puts him at a 10% caloric [1:56] deficit. He explains in some of his [1:59] videos that his philosophy is that every [2:01] calorie in his diet needs to fight for [2:04] its life. So, he's under consuming [2:07] calories every day indefinitely into the [2:10] future. And that is a really, really [2:12] controversial strategy. I'll summarize [2:15] everything we know on this topic real [2:16] quick so you can make your own informed [2:18] decision. When I was working on my PhD, [2:22] caloric restriction was huge. We talked [2:24] about it all the time and we did these [2:26] experiments. You can calorically [2:28] restrict animals in the lab like small [2:30] worms or fruit flies or even mice and [2:32] they do live longer when you do that. [2:35] It's actually pretty impressive. But you [2:37] keep these animals in an unnatural [2:39] environment in the lab where they have [2:41] access to unlimited amounts of very [2:43] caloric rations. So we always wonder, we [2:46] always have these discussions in lab [2:48] meetings. Are we just rescuing the [2:50] damage of over nutrition when we [2:53] calorically restrict or are we actually [2:56] extending the maximum lifespan of the [2:58] species? In humans, studying aging is [3:00] extremely difficult because it takes [3:02] forever. There's one recent trial that [3:04] actually tried to calorically restrict [3:06] people for a couple years and they did [3:08] see some benefit. Their blood work [3:11] improved and this biomarker of aging, [3:14] it's called an epigenetic clock that [3:16] improved as well. So, it's suggesting [3:18] that they're aging at a slower rate when [3:21] they're calorically restricted. But the [3:23] concern here is similar to the animal [3:25] research because although these [3:27] participants were not obese about half [3:29] were overweight and the average body fat [3:33] in the group was pretty high and in fact [3:35] the participants that were calorically [3:36] restricted lost some body fat. So are [3:39] the benefits just because of the fat [3:41] loss? Are we just rescuing the harms of [3:44] over nutrition which has a lot of value? [3:46] No one's arguing that. or are we [3:48] actually extending the maximum lifespan [3:51] of the human species, which is a [3:52] completely different question. So, what [3:54] does all of this mean for you? Well, if [3:57] you have some excess body fat, like most [3:59] Westerners do, then absolutely finding a [4:02] way to restrict calories to moderate [4:04] calories is going to be beneficial. And [4:06] it doesn't have to be counting calories. [4:08] There's many ways to do it. It will [4:09] reduce your waist and your blood work, [4:12] your cholesterol, your blood sugar, your [4:14] blood pressure. Everything's likely to [4:16] improve. But if you're already very [4:18] lean, very low body fat like Brian [4:20] Johnson is, and very physically active, [4:23] and eat a very clean diet with no junk, [4:26] then it's pretty uncertain if cutting [4:29] calories even more beyond that is going [4:31] to provide any benefits. And it could [4:33] even cause some harm. Loss of muscle, [4:36] loss of bone mass, hormone issues, or [4:39] some things that could go ary. Brian [4:42] Johnson does all kinds of blood work and [4:44] tests all the time. So I imagine he's on [4:46] top of that. But those are some [4:48] theoretical concerns. And so personally, [4:50] that's what I try to do as well. I [4:52] absolutely dial down the calories to [4:54] lose excess body fat to get to an ideal [4:56] body weight and body composition. But [4:59] once I'm there, I don't keep cutting [5:01] calories for the rest of my life. I just [5:03] maintain. So this is the first mindset [5:05] shift in the video. So you don't [5:07] necessarily want to just copy someone's [5:10] anecdote bit by bit exactly. You want to [5:13] understand is the benefit likely to come [5:16] from the extreme behaviors or is it [5:18] something more basic. Okay. But the next [5:20] question is even more controversial and [5:23] more relevant to you honestly and that [5:25] is how does Brian Johnson distribute [5:29] those calories in his diet? He gets [5:31] about 25% of his calories from protein. [5:34] 35% from carbs and 40% from fat. Right [5:38] off the bat, this upsets every diet [5:41] tribe on the internet. The low-faters [5:43] think it's too much fat. The low carbers [5:46] think it's too much carb. Leaving [5:47] ideology aside, we want to look at this [5:49] objectively based on the best evidence [5:52] we have. Is this approach, is this [5:54] breakdown likely to bring benefits for [5:57] you? So, let's start with protein. [5:59] There's basically two schools of thought [6:01] out there on protein and longevity. One [6:04] view is that you want to keep your [6:06] protein very low to live long. And [6:09] people often point to the work of Velter [6:11] Longo. And the rationale there is when [6:14] we eat protein, it induces IGF-1, this [6:17] growth factor. And so it might cause [6:20] cancer and speed up aging. And in fact [6:23] on his website Longo proposes a pretty [6:27] low range of protein intake of 73 grams [6:30] of protein per kilo of body weight per [6:33] day which is right under the RDA. A lot [6:37] of people already complain the RDA is [6:39] too low. Valter Longo's recommendation [6:41] is to eat slightly below that at least [6:44] until the age of 65. After 65 he [6:47] recommends more. The other school of [6:48] thought is the opposite that you want to [6:50] eat high amounts of protein. This is [6:53] championed by people like Peter for [6:55] example. And the idea there is that with [6:58] age we lose muscle mass. And so you want [7:01] to be as muscular as possible in your [7:04] middle age so that when that inevitable [7:06] muscle loss comes we still hold on to [7:09] enough muscle by our later ages. And so [7:12] you want to eat a lot of protein to get [7:14] a lot of muscle. That's basically the [7:15] rationale. And Peter Retia on his [7:17] website recommends from 1.6 to 2.2 g of [7:22] protein per kilo of body weight per day. [7:25] So it's about 2 to three times what [7:28] Velter Longo recommends. So a huge [7:30] spread. And Brian Johnson eats about 1.6 [7:33] g per kilo of body weight per day. So [7:36] that's more than twice what Velter Longo [7:38] recommends. And it's around the minimum [7:40] that Peter Aia recommends. And I agree [7:43] with Brian Johnson's approach. the [7:45] evidence backs him up. And this is [7:46] something I've changed my mind on over [7:48] the years as the evidence evolved. [7:50] During my graduate work, we published [7:53] these experiments showing that you can [7:55] restrict protein intake in model [7:58] organisms like fruit flies and you [8:00] extend their lifespan that way. But this [8:02] hasn't really translated to humans. When [8:05] we look at human data, we actually see a [8:07] lower risk of mortality for some types [8:09] of protein like plant protein for [8:12] example or some animal proteins like [8:14] fish. So this is saying that the problem [8:17] is not really protein per se. It depends [8:21] on the source. So I don't really find [8:23] longu and the low protein school of [8:25] thought very compelling. And as far as [8:28] hypertrophy, we see that maximize around [8:32] 1.6 six grams of protein per kilo of [8:35] body weight per day. So that's roughly [8:37] what I shoot for around Brian Johnson's [8:40] range or the low end of Peter's range in [8:44] that ballpark 1.5 1.6. And I pay more [8:47] attention to the source of the protein. [8:50] And this is what I recommend also for [8:52] most people because most debates online [8:55] on this topic put too much emphasis and [8:57] too much focus on the amount of protein, [9:00] which is not a problem for most [9:02] Westerners, and not enough focus on the [9:05] source of protein, which is a much [9:06] bigger issue. So, we'll come back to [9:08] this question. Right now, let's look at [9:10] some of Brian Johnson's actual meals. I [9:12] looked at his website. I looked at a [9:13] number of his videos. The details vary a [9:16] little bit, but it sounds like he eats [9:18] about three times a day, which is [9:20] normal. But all of his meals are shifted [9:23] really early. He gets up before sunrise [9:26] at 5:00 a.m. and he's done eating before [9:29] noon. [9:29] >> An hour and a half or 2 hours later, I [9:31] will have my final meal of the day. [9:33] >> That's right. He eats all of his meals [9:36] before noon. So, he eats in roughly a 6h [9:39] hour window and then he fasts the rest [9:42] of the time. the other 18 hours or 17 [9:45] and 1/2 hours, something like that. This [9:47] sounds so unusual and extreme enough [9:50] that a lot of people think this is the [9:52] secret sauce that will get you the [9:54] benefits and maybe this is what we got [9:56] to replicate. But is this backed by [9:59] evidence? Fasting per se doesn't make a [10:03] meaningful difference when you match for [10:05] calories and for meals eaten. Whether [10:07] you eat these meals more spaced out over [10:10] the course of the day or more [10:12] concentrated and then you fast the rest [10:14] of the time doesn't seem to make much [10:16] difference for body weight, metabolism, [10:19] etc. That doesn't mean the fasting is [10:20] useless. Some people like to use fasting [10:23] as a strategy to reduce calories, to [10:27] reduce the overall amount of foods eaten [10:29] or to reduce snacking and it can be very [10:32] powerful, very effective. It's just not [10:33] the fasting itself that's delivering the [10:35] results. On the other hand, this [10:37] question of timing, so eating the exact [10:40] same meals and same spacing, same amount [10:42] of fasting, but the meals shifted [10:45] earlier in the day versus later in the [10:47] day, that has some evidence to back it [10:50] up. Some studies find a benefit of [10:52] eating our calories earlier in the day, [10:54] morning and early afternoon. The effect [10:57] is not huge. It's not seen in every [10:59] study, possibly because it's relatively [11:02] small, so you don't always see it. [11:04] Bottom line, eating our calories earlier [11:06] in the day. Everything else held equal [11:09] might be a little better metabolically [11:11] than eating them later in the afternoon, [11:14] evening, and night. But don't forget the [11:16] role of food quality and overall food [11:19] quantity are much stronger. They easily [11:22] trump this effect of timing. So, do I [11:24] think you need to be doing this extreme [11:26] version that he does? I don't. We don't [11:29] have strong evidence to back that up. [11:31] That you need to eat everything in a [11:32] 6-hour window and be done by noon. If he [11:35] likes it, that's fine. I personally [11:37] don't do that. And I don't stress too [11:39] much over timing. I try to eat most of [11:42] my calories earlier in the day. I try [11:44] not to have large heavy meals at night [11:48] and that's about it. I don't lose sleep [11:50] over the exact timing of meals and I [11:52] don't do complete fasts after a given [11:55] hour. Okay, you've made it this far. [11:57] This is where we shift gears because [12:00] we've dispelled a lot of the [12:01] distractions. Now, we look at the exact [12:03] foods he eats and this is where your [12:06] benefit is likely to come from. One of [12:08] his staple meals, he calls it super [12:10] veggie. He's big on branding. I think [12:12] this a business guy thing. It's [12:14] basically a veggie bowl. It includes [12:16] lentils, mushrooms, a number of [12:18] vegetables, broccoli, cauliflower. So, [12:21] this meal gets a lot of things right [12:23] scientifically and for health benefits. [12:26] Lentils are one of the best sources of [12:27] protein out there. I have them all the [12:29] time. They come with some fiber and they [12:31] come with resistant starch. So, it's [12:34] great for your gut. Lentils are also [12:35] great for your blood sugar because [12:37] they're low glycemic index due to the [12:39] fiber. And then the cruciferous [12:41] vegetables, the broccoli, the [12:42] cauliflower, those are a good source of [12:44] sulforophane, which is a powerful [12:46] antioxidant. And then the seasonings he [12:49] uses are all fantastic. Garlic helps [12:51] lower blood pressure. Apple cider [12:53] vinegar is good for your blood sugar as [12:55] well. So yes, it's a great idea for you [12:58] to include this type of meals in your [13:00] diet. Most Westerners, it would be a [13:02] godsend if they ate more meals like [13:04] that. He also adds a tablespoon of extra [13:07] virgin olive oil. high in polyphenols to [13:11] this meal. Actually, he adds that to [13:12] most of his meals. He's big on olive [13:15] oil. In one of his videos, he even says [13:16] extravirgin olive oil is his number one [13:20] anti-aging food. That might be an [13:22] overstatement, but yeah, the evidence [13:23] for olive oil is great. It's good for [13:26] the heart. It's good for your liver. You [13:28] name it. Is olive oil uniquely good? [13:31] Probably not. I mean, any of these [13:33] healthy fats, avocados, walnuts, they're [13:36] all great. We do have a lot of evidence [13:38] for olive oil. It's been studied a ton. [13:42] So, I would say our confidence level for [13:43] olive oil is pretty high, but I wouldn't [13:45] say it's the best fat out there. It's [13:48] one of the great ones for sure. And he [13:49] also adds some fermented foods that bowl [13:52] like kimchi. Fermented foods are great [13:53] for the gut. I'm a little more cautious [13:56] with kimchi because it most of the [13:58] kimchi brands are very high in salt. I [14:01] don't know if he uses different one or [14:02] if he makes his own lower in salt or [14:04] not. Salt is another fascinating topic [14:07] because Brian Johnson doesn't add any [14:09] regular salt to his diet. Zero. Although [14:12] one of his supplements contains some [14:14] Himalayan pink salt. So he's not on zero [14:17] added salt, but he doesn't add any to [14:19] foods and none of the regular salt. So [14:21] what does that mean for you? Do you have [14:23] to add salt? Sometimes people ask me if [14:26] we need to add some salt to foods. We [14:28] don't need to add salt. We need sodium. [14:30] Sodium is an essential nutrient, but the [14:32] amount we need is actually pretty small. [14:34] And sodium is included in all kinds of [14:36] foods. Vegetables, animal foods, they [14:38] all contain sodium. So you don't need to [14:39] add salt to food. Now whether adding it [14:42] is good or bad depends on the [14:43] individual. Most westerners over consume [14:46] sodium and their blood pressure is a [14:48] little too high and they would benefit [14:50] by cutting back. Although a lot of the [14:52] sodium comes in ultrarocessed foods, not [14:54] necessarily added at the table. But [14:56] individually, some people see their [14:58] blood pressure skyrocket when they add [15:00] salt. Some people are much more salt [15:02] tolerant. They can handle more. Some [15:04] people even have inverse salt [15:06] sensitivity. So you take away the sodium [15:08] and their blood pressure goes up. It's [15:09] unusual. It's about 10% of people, but [15:12] it's a thing. So I think it makes sense [15:14] when it comes to salt to personalize for [15:16] your nature and your goals. And as for [15:19] these fancy salts, the Himalayan pink [15:21] salt and the Baja sea salt, it's mostly [15:23] hype. We looked at this in a previous [15:25] video. No matter where the salt comes [15:26] from and what color it is, it's still [15:28] going to be overwhelmingly sodium [15:31] chloride, 98 or 99%. So, it's still [15:34] going to have the same effects on blood [15:35] pressure as regular salt. The argument [15:38] for these fancy salts usually is the [15:41] trace minerals, but when you look into [15:43] this, and we covered that in that [15:44] previous video, the amount of those [15:46] trace minerals is minuscule. So, it [15:49] really doesn't make a difference [15:50] nutritionally. There's a study that [15:51] quantified this. They estimated that in [15:54] order to get a meaningful amount of [15:55] trace minerals from pink salt, you'd [15:58] need to get six times the maximum amount [16:01] of sodium recommended. So for most [16:04] people, that would just skyrocket blood [16:06] pressure. It's stepping backwards. Save [16:08] your money with these fancy salts. It's [16:11] mostly hype. Take it with a grain of [16:13] salt. Sorry. Just use regular salt. And [16:15] if your blood pressure is high and you [16:17] want to lower it, potassium salt is one [16:20] option. That's actually evidence-based. [16:22] That's what I use at home. Okay. Another [16:24] example of meal that Brian Johnson gives [16:26] is a sweet potato curry with quinoa. It [16:29] includes sweet potato, quinoa, broccoli, [16:32] cauliflower, green beans, and some [16:35] seasonings and spices as well. So, his [16:37] meals are definitely fiber richch. [16:39] They're antioxidant rich. That he nails. [16:42] There's no argument there. Just to [16:44] illustrate this, a recent study asked [16:46] which foods are more strongly linked to [16:49] healthy aging, which they defined as [16:52] preserving all aspects of health and [16:54] living to the age of 70 without chronic [16:56] disease. Fruits, vegetables, whole [16:59] grains, unsaturated fats, nuts, legumes, [17:03] and low-fat dairy were linked to better [17:05] odds of healthy aging. And then trans [17:08] fats, sodium, sugary beverages like soda [17:12] and red and processed meats were linked [17:15] to warons. And so, as you can see, Brian [17:17] Johnson nails almost every item that [17:21] study found with the exception of dairy, [17:24] which we'll come back to. Now, this is [17:27] where most content on longevity fails [17:30] miserably because most people focus on [17:33] details and fads and expensive [17:35] supplements that give you little to no [17:37] benefit. Whereas Brian Johnson's diet [17:40] actually gets the fundamentals right, [17:43] and that's what's going to deliver [17:44] results. The irony is that Brian Johnson [17:47] is often seen as a fad guy, but his diet [17:50] actually snubs every fad. He's not [17:52] scared of fats, but he chooses healthy [17:54] fats. He's not carbopobic. He's not [17:57] terrified of carbs, but he chooses the [17:59] best sources of carbs, whole grains, [18:01] legumes, fruits, and vegetables. So on [18:04] that chapter, he aced it scientifically. [18:07] One recent study estimated that a diet [18:10] with whole grains, legumes, fish, [18:13] fruits, vegetables, and nuts, if started [18:16] at an early age, would extend life by [18:19] more than 10 years compared to a [18:20] standard American diet. And the largest [18:22] gains would come from eating more [18:24] legumes, more whole grains, and more [18:27] nuts. So, we're starting to answer that [18:29] initial question we posed in the [18:31] beginning of the video. When we strip [18:33] away all the hype and all the [18:35] showmanship, what remains that's [18:37] actually going to deliver you the [18:39] results are some of the most [18:41] sciencebacked foods on Earth. Okay. But [18:43] there's an important question left for [18:46] you and your diet. Brian Johnson doesn't [18:48] include any animal products. He's not [18:50] entirely vegan because he has a collagen [18:53] supplement in there that is from animal [18:55] origin, but his foods are all [18:58] plant-based. So, do you need to do that [19:00] to extend life and to avoid disease? He [19:02] explains in some interviews that he's [19:04] vegan by choice, not by need. [19:06] >> I'm vegan by choice. [19:08] >> So, he doesn't think that animal [19:10] products necessarily harm you. And the [19:13] science backs him up on that. For [19:14] example, one study looked at Adventists [19:17] from California, which are known famous [19:19] for their longevity, and they separated [19:21] them by diet. So, the omnivores, the [19:24] vegans, the vegetarians, the [19:25] pescatarians, and the pescatarians were [19:27] actually the only ones that had [19:29] significantly lower mortality than the [19:31] omnivores. The other plantrich diets, [19:34] the vegans, vegetarians, etc., they [19:36] trended towards lower, but didn't reach [19:38] statistical significance. And as we [19:40] said, fish is generally linked to, if [19:43] anything, lower mortality. So you don't [19:46] have to be completely plant exclusive [19:49] for health, for longevity, but you do [19:51] want to have a diet that is high in [19:54] fiber and high in plants. Now, his [19:56] reason for eating a vegan diet is [19:58] actually really interesting. He says [19:59] that AI is about to dominate us real [20:02] soon, and it's going to model its [20:04] behavior on ours, on whatever it sees us [20:07] doing. And so we want to show compassion [20:09] over creatures that we dominate so that [20:12] AI sees it and does the same thing to us [20:15] and doesn't treat us like trash. It's an [20:18] interesting argument. It's almost [20:21] ethics for a self-s serving reason. You [20:24] let me know your thoughts on that. Brian [20:25] Johnson has also shared some of his [20:27] favorite desserts or snacks. One is what [20:30] he calls nutty pudding. It's basically a [20:32] mix of nuts, seeds, berries with some [20:36] cocoa, and some bee protein mixed in as [20:39] well. So, a lot of healthy fats, a lot [20:41] of antioxidants. Smart choices. No [20:43] question about that. In addition to all [20:45] of his food, he also takes a plethora of [20:48] supplements. I mean, I think it's 50 or [20:50] 100 different supplements a day. That's [20:53] a an a whole video by itself. Suffice to [20:55] say, for today, I don't take the [20:57] majority of the supplements he takes. I [20:59] don't think they have very strong [21:01] evidence. I'll only touch on a couple [21:03] exceptions. B12, for someone like him [21:05] who's on an plant exclusive diet, you [21:09] need a source of B12. I checked. He does [21:11] supplement that. Vitamin D, he said he's [21:13] not in the sun much. He doesn't eat [21:15] dairy. He doesn't eat fish. So, there's [21:16] no source of vitamin D in his diet. I [21:19] checked. He supplements that as well. [21:21] 2,000 international units a day. The RDA [21:24] is only 600 for an adult, but 2,000 is [21:27] fine. It's not a dangerous dose. He also [21:29] takes an algae oil for EPA, DHA, these [21:32] long form omega-3s. The evidence is not [21:35] super convincing, but there's some [21:36] evidence suggesting benefit or the [21:38] brain, maybe the heart, particularly for [21:41] people who don't have EPA in their diet. [21:45] And algae oil has been shown to be [21:46] absorbed just fine, just like fish oil. [21:49] And it might actually be cleaner, lower [21:51] in contaminants because of the way the [21:52] algae are grown. As for organic or [21:55] conventionally raised, and this might [21:57] surprise you, he is pretty cynical about [22:00] organic food, he doesn't buy that it's [22:03] uh beneficial, and that's actually a [22:05] reasonable take. Despite all the hype, [22:07] we have no compelling evidence that [22:08] organic food provides any clear benefit. [22:12] So, it's personal preference. I also [22:13] don't worry much about it. I by [22:15] conventionally raised almost always. But [22:17] the main thing is to eat healthy foods. [22:19] Eat fruits and vegetables and all those [22:21] good things. Whether they're organic or [22:22] not is up to you. Okay. Drinks. He has [22:25] this green smoothie that's basically [22:27] spinach, kale, banana, cherry, and then [22:30] some nuts and seeds. He also has water [22:33] of course, and then tea. And he has this [22:35] drink that basically he took a bunch of [22:36] supplements and made them into a liquid [22:38] form. Other than that, he drinks zero [22:41] alcohol, zero soda, actually zero [22:44] refined sugar in all of his diet. And [22:47] those are good choices as well. Okay, [22:49] now let's get into the most useful part, [22:50] the most actionable part. If you want [22:53] Brian Johnson's results, but you don't [22:54] want to be Bryant Johnson, this is what [22:58] I would actually recommend to a friend. [22:59] Rule number one, remove the junk. Sugary [23:02] drinks, processed meats, artificial [23:04] desserts, fried fast foods, [23:07] ultrarocessed snacks. Getting rid of [23:09] that is the most bang for your buck. [23:10] Rule number two, the fiber foundation. [23:13] Legumes vegetables fruits whole [23:16] grains, nuts, and seeds. These should be [23:20] staples of the diet that you have daily. [23:22] Good for the heart, good for the gut, [23:24] good for the brain, you name it. If you [23:26] want one cheap longevity food, add more [23:29] legumes to your diet like beans and [23:31] lentils. Rule number three, best fats. [23:35] Olive oil, nuts, seeds, avocados, fish [23:39] and seafood, fermented dairy. You don't [23:41] need less fat in your diet. You need [23:44] better fats. Rule number four, enough [23:46] protein but from great sources. Beans, [23:49] lentils, fish, seafood, lean meats. This [23:52] is especially important if you're older, [23:54] over 65, if you're very physically [23:56] active, or if you're trying to lose [23:58] weight. And protein powder is fine, too, [24:00] if you need a little extra. Rule number [24:02] five, cover any nutrient gaps. If your [24:05] diet is plant exclusive, have some B12. [24:08] If you don't catch much sun, you might [24:10] need a vitamin D supplement. If you [24:12] don't eat regular salt or fish or dairy, [24:15] you might need to supplement iodine, [24:18] etc. So, that answers our initial [24:20] question. When we strip away all the [24:22] money and all the flash and all the [24:24] branding, the healthy core is very [24:27] simple. Remove the junk, eat healthy [24:29] foods most of the time, and address any [24:31] nutrient gaps. Brian Johnson had an [24:34] entire team research and design this [24:37] diet with endless resources, and you can [24:39] get the same benefits at home cheap. Is [24:42] this diet going to make you immortal? Of [24:44] course not. It's going to help you avoid [24:47] disease and age as gracefully as [24:50] possible.
