Summary

TLDRThe video explores the best longevity diet, debunking popular diets like keto, vegan, and Mediterranean. It emphasizes weight control due to rising obesity rates and their health implications. Research from 2014 to 2020 suggests any diet can lead to weight loss, but maintaining it is challenging. The video advocates for a diet that includes high lean protein intake, unsaturated fats, low sodium, and prioritizes whole foods, fruits, and vegetables. The key takeaway is that the best longevity diet is one that is sustainable and tailored to individual needs, focusing on overall health and well-being.

Takeaways

  • 🍽️ The best longevity diet isn't specific to any one trend like keto, vegan, carnivore, or Mediterranean, but rather focuses on what the individual can adhere to long-term.
  • 📉 A key priority of a longevity diet is to help control weight, as obesity rates are high and linked to various health issues like diabetes and hypertension.
  • 🔍 Research from randomized control trials shows that both low-carb and low-fat diets can lead to significant weight loss, with little difference between the two after a year.
  • 🔁 The difficulty lies in maintaining weight loss long-term, as the body tends to fight against it, with over half the weight lost typically regained within two years.
  • 🥩 The concept of a carbohydrate-insulin model of obesity has been proposed, suggesting that high-carb diets are more fattening due to increased insulin secretion, but this has not held up in trials.
  • 🥦 Fundamentals for designing a longevity diet include reducing refined carbs and sugars, replacing sugary drinks with water, and prioritizing whole foods, especially non-starchy vegetables for their fiber content.
  • 🥚 High protein intake, particularly lean protein, can help with weight control and is associated with lower all-cause death rates, potentially due to its role in maintaining muscle mass.
  • 🏋️‍♂️ Resistance exercise combined with a high-protein diet can maximize muscle strength, which is linked to lower all-cause death rates.
  • 🍳 The type of protein matters, with animal-based proteins typically being rich in leucine, an essential amino acid for muscle protein synthesis, important for plant-based diets to consider.
  • 🥑 Unsaturated fats, found in foods like avocados, nuts, seeds, and extra virgin olive oil, are beneficial for heart health and should replace saturated fats in the diet.
  • 🧂 Reducing sodium intake, particularly from processed foods, can help lower blood pressure and reduce the risk of heart attacks and strokes.
  • 🥦 A diet rich in fruits and vegetables provides essential nutrients like potassium and fiber, which help to lower blood pressure and promote satiety.

Q & A

  • What is the main focus of the video script regarding diets?

    -The main focus of the video script is to explore the best longevity diet that helps control weight and improve the quality of life, while also discussing the effectiveness of various diets in weight loss and maintaining muscle mass.

  • Why is controlling obesity a top priority when selecting a diet?

    -Controlling obesity is a top priority because it is linked to numerous health issues such as diabetes, high blood pressure, arthritis, severe back pain, sleep apnea, and fatty liver, which can significantly impair the quality of life.

  • What did the 2014 review of diet literature find regarding weight loss?

    -The 2014 review found that significant weight loss was observed with any low carbohydrate or low-fat diet after a 12-month period, and the differences between the different diets were small, suggesting that adherence is key to weight loss success.

  • How does the 2020 study published in the British Medical Journal differ from previous analyses?

    -The 2020 study is more comprehensive, involving over 121 randomized control trials with nearly 22,000 participants, testing 14 different diets and reinforcing the idea that weight loss effects are broadly the same over the long term, regardless of the diet type.

  • What does Professor Kevin Hall's research suggest about weight loss?

    -Professor Kevin Hall's research indicates that more than half of the lost weight is regained within 2 years, and by 5 years, over 80% of the weight is regained, suggesting that the body fights against weight loss.

  • What is the carbohydrate-insulin model of obesity, and has it been supported by research?

    -The carbohydrate-insulin model of obesity posits that diets high in carbohydrates increase insulin secretion, which in turn drives fat accumulation. However, multiple randomized control trials have shown that this model has failed experimental interrogation.

  • What are the critical fundamentals for designing the perfect longevity diet?

    -The critical fundamentals include reducing refined carbs and sugar, replacing fizzy drinks and juices with water, prioritizing whole foods and non-starchy vegetables, ensuring whole grains are not refined or mixed with sugar, and having a small early dinner followed by brushing teeth to signal the end of eating for the day.

  • How does protein intake affect weight regain and muscle mass?

🍽️ The Quest for the Best Longevity Diet

The first paragraph introduces the topic of the best diet for longevity, emphasizing the importance of weight control due to the rising obesity rates and their associated health risks. It highlights a 2014 review of diet literature that found significant weight loss with any low-carb or low-fat diet, but with minimal differences between diets. The paragraph also mentions a 2020 study from the British Medical Journal that supports the idea that various diets can lead to weight loss, but maintaining this weight loss is challenging. It introduces the concept of the carbohydrate-insulin model of obesity and the recent resurgence of low-carb diets, but notes that this model has not held up in experimental studies. The paragraph concludes by suggesting that a high-protein diet, combined with resistance exercise, can help maintain muscle strength and potentially improve longevity.

05:02

🥚 Balancing Protein Intake for Optimal Health

The second paragraph delves into the debate over protein intake, referencing studies that suggest both high and low protein diets may have benefits. It discusses the importance of leucine, an essential amino acid found in animal-based proteins, and the need for plant-based dieters to consume more protein to achieve the same leucine intake. The paragraph addresses concerns about high protein intake and kidney health, citing studies that show no adverse effects. It also emphasizes the importance of unsaturated fats over saturated fats for heart health, and the benefits of reducing sodium intake to lower blood pressure. The paragraph concludes with a call to prioritize high lean protein intake, replace saturated fats with unsaturated fats, reduce sodium, and increase potassium and fiber intake from fruits and vegetables for a longevity diet.

10:03

💊 Supplements and Personalized Diet Approach

The final paragraph touches on the use of dietary supplements, such as microv, to help meet daily vitamin and mineral requirements without the risk of over-supplementation. It emphasizes the importance of personalization in diet choices, suggesting that what works for one person may not work for another. The paragraph also encourages viewers to watch the next video for strategies to reduce the risk of heart attacks and expresses gratitude to the patrons supporting the channel.

Keywords

💡Longevity Diet

A longevity diet refers to a dietary pattern aimed at promoting health and extending lifespan. In the video, the concept is explored in the context of different diets like keto, vegan, carnivore, and Mediterranean, and how they may or may not contribute to longevity. The script emphasizes that the best longevity diet is one that can be adhered to over the long term, with a focus on weight control and overall health.

💡Obesity

Obesity is a medical condition characterized by excessive body fat. The script highlights the importance of controlling obesity rates, which are linked to various health issues such as diabetes, high blood pressure, and arthritis. The goal of a great diet, as mentioned, is to prevent, treat, or reverse the complications of obesity and improve the quality of life.

💡Weight Loss

Weight loss is the reduction of body mass, typically through a combination of diet and exercise. The video discusses various studies that show significant weight loss can be achieved with different types of diets, such as low-carbohydrate or low-fat diets. However, it also points out the difficulty of maintaining long-term weight loss, which is a central theme in the discussion of diet effectiveness.

💡Carbohydrate Insulin Model of Obesity

This model suggests that diets high in carbohydrates are fattening because they increase insulin secretion, which in turn drives fat accumulation. The video mentions this concept in the context of low-carbohydrate diets and their reemergence to combat weight regain. However, it also notes that this model has not held up under experimental scrutiny.

💡Protein Intake

Protein intake is the consumption of protein-rich foods, which are essential for muscle growth and repair. The script discusses the role of high protein diets in reducing weight regain and their association with lower all-cause death rates, as supported by a 2020 meta-analysis. It also mentions the optimal amount of protein intake per body weight for maximizing the benefits of exercise.

💡Muscle Mass

Muscle mass refers to the total amount of muscle tissue in the body. The video points out that higher muscle strength is associated with lower all-cause death rates, emphasizing the importance of maintaining muscle mass throughout life. High protein diets and resistance exercise are suggested as ways to achieve this.

💡Saturated Fat

Saturated fat is a type of fat found primarily in animal products and some plant-based oils. The script discusses the negative health impacts of high saturated fat intake, such as increased risk of heart disease, and suggests replacing saturated fats with unsaturated fats for better health outcomes.

💡Unsaturated Fat

Unsaturated fat is a type of fat that is considered healthier than saturated fat and is found in foods like avocados, nuts, seeds, and olive oil. The video mentions the benefits of unsaturated fats, citing a study that found the Mediterranean diet, rich in unsaturated fats, to be superior for preventing cardiovascular events.

💡Sodium Intake

Sodium intake refers to the consumption of sodium, typically in the form of salt. The script explains that high sodium intake can lead to increased blood pressure, which is a risk factor for heart attacks and strokes. It suggests reducing sodium intake, especially from processed foods and restaurant meals.

💡Fruits and Vegetables

Fruits and vegetables are rich sources of vitamins, minerals, fiber, and potassium. The video emphasizes the importance of including these in a longevity diet for their health benefits, such as helping to lower blood pressure and promoting a feeling of fullness.

💡Microv (Supplement)

Microv, or a vitamin supplement, is mentioned as a way to ensure the recommended daily intake of vitamins and minerals without the risk of over-supplementation. The script notes that while the speaker takes a supplement, it is not a recommendation for everyone, and individuals should consider their own needs.

Highlights

The best longevity diet is not strictly keto, vegan, carnivore, or Mediterranean, and the video will reveal the best diet at the end.

A top priority of a diet is to control weight, as over 42% of people are now obese, which is linked to various health issues.

A 2014 review of 48 randomized control trials showed that both low-carb and low-fat diets resulted in significant weight loss after 12 months.

The 2016 analysis confirmed that various diets can aid weight loss, but long-term weight maintenance is challenging.

A 2020 study in the British Medical Journal included 121 trials and found similar weight loss effects across different diets after 12 months.

More than half of lost weight is regained within 2 years, and over 80% by 5 years, indicating the body's resistance to weight loss.

Low-carb diets have reemerged to combat weight regain, based on the carbohydrate-insulin model of obesity, but this model has failed experimental tests.

There is no one-size-fits-all diet for weight loss, but some fundamental principles can be used to design the perfect longevity diet.

Refined carbs, sugar, and unhealthy beverages should be reduced, with an emphasis on whole foods and non-starchy vegetables.

High protein intake, especially lean protein, can help with weight control and is associated with lower all-cause death rates.

A 2020 meta-analysis showed that higher protein intakes are linked to lower mortality rates, possibly due to increased muscle mass.

The optimal protein intake per kilogram of body weight per day is 1.6g to maximize the benefits of exercise.

Some longevity scientists suggest lowering protein intake, but human clinical research should be prioritized over lab animal studies.

Lucine, an essential amino acid in animal-based proteins, is crucial for muscle protein synthesis, which is important for plant-based diets as well.

High protein intake and its impact on kidney health have been studied, with no clear evidence linking it to adverse outcomes.

Reducing saturated fats and replacing them with unsaturated fats like avocados, nuts, seeds, and olive oil can lower heart disease risk.

High sodium intake is linked to increased blood pressure and should be reduced, especially from restaurant and packaged foods.

Fruits and vegetables are rich in potassium and fiber, which help lower blood pressure and promote fullness.

The best longevity diet is one that can be sustained long-term, reducing cancer and heart disease risk factors.

Diet fundamentals include reducing refined carbs, sugars, and sodium, prioritizing whole foods, high lean protein, unsaturated fats, and fruits and vegetables.

Taking vitamins and supplements can help reach recommended daily intakes without the risk of over-supplementation.

end a top priority in selecting a diet

play00:14

is making sure that that diet helps to

skyrocketing over 42% of us are now

play00:36

complications of obesity and improve the

play00:38

quality of life so which diet is best

play00:41

for weight loss well one of the most

play00:43

famous reviews of the diet literature

play00:45

was published in 2014 it combined over

play00:48

48 unique randomized control trials that

play00:51

looked at a variety of different diets

play00:53

and included a total of over 7,000

play00:55

individuals after a 12-month period

play00:58

significant weight loss was observed

play01:00

with any low carbohydrate or lowfat diet

play01:03

and the differences between the

play01:04

different diets were small this supports

play01:07

the practice of recommending a diet that

play01:09

a patient will adhere to in order to

play01:11

lose weight but that was 2014 what has

play01:14

happened since then another analysis was

play01:16

done in 2016 that also found that a

play01:19

variety of different diets can help with

play01:21

weight loss but the 2014 and 2016

play01:24

analyses pale in comparison to the one

play01:26

that was published in the British

play01:27

medical journal in 2020 this one

play01:30

involved over 121 randomized control

play01:32

trials involving just under 22,000

play01:35

people the individual trials tested 14

play01:38

different diets and once again at the

play01:40

12-month period the weight loss effects

play01:43

were broadly the same over and over

play01:45

again the studies show the same thing

play01:47

people can lose weight over the short

play01:49

term but it's incredibly difficult to

play01:51

keep that weight off over the long term

play01:53

so why does this happen and what can be

play01:55

done about it well one of the most

play01:57

famous diet researchers Professor Kevin

play01:59

Hall wanted to answer this in 2018 in a

play02:02

shocking statistic more than half of the

play02:05

lost weight is regained within 2 years

play02:07

and by 5 years more than 80% of the lost

play02:10

weight is regained unfortunately it

play02:12

appears that the body fights this weight

play02:14

loss so in recent years there's been a

play02:17

reemergence of low carbohydrate diets to

play02:19

help fight this weight regain it centers

play02:22

around a concept called the carbohydrate

play02:24

insulin model of obesity which posits

play02:27

that diets high in carbohydrates are

play02:29

particularly fattening because they

play02:31

increase the secretion of insulin and

play02:33

thereby Drive fat accumulation

play02:35

unfortunately though multiple randomized

play02:38

control trials have been done which were

play02:40

included in the metaanalyses that we

play02:41

went through in this video and overall

play02:43

it shows that the carbohydrate insulin

play02:45

model of obesity has failed experimental

play02:48

interrogation so overall what diet is

play02:51

best to help us stay at a healthy weight

play02:53

and fight the weight regain well there's

play02:56

no one siiz fits all diet for weight

play02:57

loss but there are some critical

play02:59

fundamental that we're going to build

play03:00

upon when designing the perfect

play03:02

longevity diet we know that we need to

play03:04

reduce refined carbs and sugar I don't

play03:07

need to tell you that we need to cut

play03:08

down on chips biscuits and cupcakes we

play03:11

want to replace fizzy drinks and juices

play03:13

including fruit juice with water we want

play03:15

to prioritize Whole Foods including

play03:17

non-starchy vegetables for the fiber

play03:20

content and if someone wants to consume

play03:22

whole grains like I do we need to make

play03:24

sure that they are truly whole grains

play03:26

not refined and not mixed in with sugar

play03:28

we want to eat a small early dinner and

play03:31

then immediately brush our teeth that's

play03:33

an incredibly powerful signal that

play03:35

eating has finished for the day but most

play03:37

of us already know all of that instead

play03:39

what most people don't know is how we

play03:41

can use protein to help keep the weight

play03:43

off in a randomized control trial of 773

play03:47

participants the group that was on the

play03:49

high protein diet had less weight regain

play03:52

compared to those in a low protein diet

play03:54

and a high protein intake is not just

play03:56

for weight control a 2020 metaanalysis

play03:59

public in the British medical journal

play04:01

showed that higher protein intakes are

play04:03

associated with lower all cause death

play04:05

rates that effect is probably to do with

play04:08

muscle mass a growing body of evidence

play04:10

suggests that higher muscle strength is

play04:12

associated with lower all cause death

play04:15

rates we want to maximize our muscle

play04:17

strength in youth maintain that muscle

play04:19

strength in adult life and minimize the

play04:21

loss in older life and high protein

play04:24

diets mixed in with resistance exercise

play04:26

can help us do that specifically from a

play04:29

2018 metanalysis the magic number that

play04:31

we're after is 1.6 G of lean protein

play04:34

intake per kilogram of body weight per

play04:37

day that amount of protein appears to

play04:39

maximize the benefits of exercise now it

play04:41

used to be thought that we had to have

play04:43

hits of protein intake as in we had to

play04:45

have multiple meals of protein spaced

play04:48

throughout the day and while that

play04:49

strategy may offer a small additional

play04:52

benefit most of the benefit comes from

play04:54

Total daily protein intake as per an

play04:57

important study that was published this

play04:59

year 24 but before considering high

play05:02

protein intake for the optimal longevity

play05:04

diet we need to have a look at the other

play05:06

side because some longevity scientists

play05:08

such as Professor Volta Longo suggest

play05:11

that we should be lowering our protein

play05:12

intakes referencing studies such as this

play05:15

one from 2014 this study tested 25

play05:18

different diets on mice and it found

play05:20

that the diet that had the lowest

play05:21

protein intake was associated with the

play05:24

longest lifespan but it's important to

play05:26

remember that our lives are vastly

play05:28

different to those of lab mice we need

play05:30

to optimize for resiliency in the real

play05:33

world we're exposed to viruses bacteria

play05:36

pollution attacks on our immune system

play05:38

and it's a classic case that we need to

play05:40

put far more attention on the human

play05:42

clinical research rather than what

play05:44

happens in lab animals to wrap up the

play05:46

high protein section of this video what

play05:49

types of proteins are best well When

play05:51

selecting protein sources an important

play05:53

factor to consider is their Lucine

play05:55

content Lucine is an essential amino

play05:58

acid and it plays a role in initiating

play06:01

muscle protein synthesis animal-based

play06:03

proteins are typically rich in Lucine so

play06:06

for those following a plant-based diet

play06:08

achieving the same amount of Lucine

play06:10

intake requires a higher overall protein

play06:13

consumption and there are fantastic

play06:15

plant-based protein sources that you can

play06:17

consider for example chickpeas lentils

play06:20

and pea protein powder soy protein is

play06:22

another option and despite all of the

play06:24

noise on social media we've got

play06:26

fantastic human research showing that

play06:28

soy protein has no effect on

play06:29

testosterone levels or estrogen in men

play06:32

speaking of social media you may hear

play06:34

some people talking about the concerns

play06:36

of high protein intakes and Kidney

play06:38

Health multiple human Studies have

play06:40

looked at this and overall there's a

play06:42

lack of scientific evidence linking

play06:44

higher protein intakes to adverse

play06:46

outcomes so in addition to the longevity

play06:49

diet fundamentals that we've already

play06:50

gone through we should add High lean

play06:52

protein intake to that list but why do I

play06:55

mention lean protein and this leads us

play06:57

nicely into talking about different typ

play06:59

of dietary fats we've got fantastic

play07:02

evidence from Cochran that cutting down

play07:04

on saturated fat intake leads to a 17%

play07:07

reduction in the risk of heart disease

play07:09

saturated fat is typically from animal

play07:11

sources but it's important to remember

play07:13

that unsaturated fats can be brilliant

play07:15

for us in 2022 a study called the cordio

play07:18

priv study was conducted and it compared

play07:20

the Mediterranean diet which is rich in

play07:23

unsaturated fats to a lowfat diet over

play07:26

1,000 patients were included and they

play07:28

were followed up for 7 years the study

play07:30

found that for secondary prevention the

play07:33

Mediterranean diet was superior to the

play07:35

lowfat diet in preventing major

play07:37

cardiovascular events so unsaturated

play07:40

fats can be brilliant for us this

play07:42

includes things like avocados nuts seeds

play07:44

extra virgin olive oil and certain types

play07:47

of fish so we'll add to our list that we

play07:49

should replace saturated fat with

play07:51

unsaturated fat next is salt intake

play07:54

specifically sodium we've got great

play07:56

evidence showing that as sodium intake

play07:58

increases so too does our blood pressure

play08:01

not what we want it puts needless strain

play08:03

on our blood vessels and contributes to

play08:05

heart attacks and strokes and about 80%

play08:08

of the sodium intake in the United

play08:10

States comes from restaurant and

play08:12

packaged foods and while many people

play08:14

enjoy the taste of salt the taste of

play08:16

salt is malleable meaning that if you

play08:18

cut out salt from your diet your food

play08:20

May taste a bit Bland for 4 to 6 weeks

play08:23

but if you get through that the taste

play08:24

buds adjust and your flavor comes back

play08:27

so we'll add low sodium intake to our

play08:29

list and the final concept I want to

play08:31

discuss which I've briefly touched on

play08:33

earlier in the video is fruit and

play08:35

vegetable intake fruits and vegetables

play08:37

are rich in potassium and potassium

play08:40

helps to lower our blood pressure fruits

play08:42

and vegetables are also rich in fiber

play08:44

fiber helps us to feel Fuller for longer

play08:47

so what's the best longevity diet to

play08:49

help you live a healthy 90 plus years

play08:51

the best longevity diet is the diet that

play08:54

you can stick to over the long term one

play08:56

that makes you feel energized and

play08:58

decreases your canc cancer risk and

play09:00

heart disease risk factors When

play09:02

selecting and designing a diet there are

play09:04

some fundamentals that we should try and

play09:05

stick to we want to reduce refined carbs

play09:08

and sugar replace fizzy drinks and

play09:10

juices including fruit juice with water

play09:13

we want to prioritize Whole Foods and if

play09:15

you do consume whole grains make sure

play09:17

that they're whole and not mixed in with

play09:19

sugar have a small early dinner and then

play09:22

immediately brush your teeth we want to

play09:24

prioritize a high lean protein intake

play09:27

aiming for 1.6 G of protein intake per

play09:30

kilogram of body weight per day we want

play09:32

to replace saturated fats with

play09:34

unsaturated fats such as avocados nuts

play09:38

seeds extra virgin olive oil and some

play09:40

types of fish we want to reduce salt

play09:42

intake and as part of that avoid

play09:44

processed foods and watch out for

play09:46

sources because often sauces are packed

play09:49

with salt finally non-starchy vegetables

play09:52

and fruits are fantastic for potassium

play09:54

and fiber intake in addition to those

play09:56

diet fundamentals I also take microv

play09:58

vitamin to help me reach the recommended

play10:00

daily intakes of vitamins and minerals

play10:03

without the risk of mega dosing but

play10:05

remember that just because I take a

play10:06

supplement does not in any way mean that
