How Much do these 5 Health Habits Extend your Life? [Study 247]

Summary

This video script delves into the impact of daily habits on personal life expectancy, referencing a comprehensive study that quantifies the effects of five key health factors: smoking, physical activity, alcohol consumption, BMI/weight, and diet. It reveals that adhering to a healthy lifestyle, including never smoking, regular exercise, moderate alcohol intake, a balanced BMI, and a nutritious diet, can significantly reduce the risk of death and potentially extend life expectancy by over a decade, especially for those aged 50 to 75.

Takeaways

• 🧠 The study aims to quantify how much our daily habits affect personal life expectancy, focusing on individual actions rather than average life expectancy across regions.
• 📚 The research analyzed data from three large datasets involving hundreds of thousands of people, focusing on five primary health factors: smoking, physical activity, alcohol consumption, BMI and weight, and diet.
• 🚭 Never smoking was considered the healthiest for the smoking category, with past smokers and current smokers categorized based on their smoking habits.
• 🏃‍♂️ For physical activity, healthiness was defined as over 30 minutes a day of moderate to vigorous exercise.
• 🍻 Alcohol consumption was categorized as moderate, with a daily limit of 30 grams for men and half that for women.
• 🍽️ BMI was used as a proxy for weight, with a healthy range defined as 18.5 to 24.9.
• 🥗 A healthy diet was characterized by high consumption of vegetables, fruits, whole grains, polyunsaturated fats, omega-3 fats, and low intake of processed meats, sugars, trans fats, and sodium.
• 📊 The data showed that adherence to healthy habits significantly reduced the risk of death from all causes, with a stepwise decrease in risk as more healthy habits were adopted.
• 👵🏻 Age was a significant factor, with the benefits of healthy habits decreasing as age increased, but still showing a reduced risk of death compared to those with no healthy habits.
• 🔢 The estimated life extension benefit of following five healthy lifestyle factors was substantial, with women at 50 years old predicted to gain 14 years and men at 50 gaining about 2 years less.

Keywords

💡Life Expectancy

Life expectancy refers to the average number of years a person is expected to live, based on various factors such as health, lifestyle, and environmental conditions. In the video, life expectancy is a central theme as it explores how individual habits can impact one's personal life expectancy, rather than the average life expectancy of a population.

💡Healthy Habits

Healthy habits are behaviors that contribute to overall well-being and longevity. The video discusses a study that quantifies the impact of healthy habits on life expectancy, focusing on five primary health factors. These habits are crucial in determining the potential increase in life span and are the core of the video's message.

💡Primary Health Factors

Primary health factors are the key determinants of an individual's health status. The video identifies five such factors: smoking, physical activity, alcohol consumption, BMI and weight, and diet. These factors are analyzed to understand their individual and combined effects on life expectancy.

💡Smoking

Smoking is a significant risk factor for various health issues, including cancer and cardiovascular diseases. In the video, it is one of the five primary health factors considered. The study mentioned in the video categorizes people based on their smoking habits, with 'never smoking' being the healthiest category.

💡Physical Activity

Physical activity is crucial for maintaining good health and is one of the primary health factors discussed in the video. It is defined as engaging in over 30 minutes a day of moderate to vigorous exercise. The video emphasizes the importance of physical activity in reducing the risk of death and increasing life expectancy.

💡Alcohol Consumption

Alcohol consumption is another primary health factor that can impact life expectancy. The video defines moderate consumption as up to 30 grams a day for men and half that for women. Excessive alcohol intake is associated with health risks, while moderate consumption is considered part of a healthy lifestyle.

💡BMI

BMI, or Body Mass Index, is a measure used to assess whether a person has a healthy body weight for their height. In the video, a BMI between 18.5 and 24.9 is considered healthy. BMI is used as a proxy for weight in the study, indicating its importance in determining overall health and life expectancy.

💡Diet

Diet is a critical component of a healthy lifestyle and is one of the primary health factors in the video. A healthy diet is characterized by high consumption of vegetables, fruits, whole grains, and healthy fats, with low intake of processed meats, sugars, trans fats, and sodium. The video discusses how diet can significantly influence life expectancy.

💡All-Cause Mortality

All-cause mortality refers to the total number of deaths from any cause within a specific population. In the video, all-cause mortality is used to measure the impact of healthy habits on life expectancy. The study shows that adopting healthy habits can reduce the risk of death from all causes.

💡Life Extension Benefit

Life extension benefit is the additional years of life that can be gained by adopting a healthy lifestyle. The video provides data on the estimated life extension benefit of following various healthy lifestyle factors, illustrating the tangible impact of these habits on increasing life expectancy.

💡Confounding Variables

Confounding variables are factors that can influence the relationship between a cause and its effect, potentially leading to incorrect conclusions. The video acknowledges that while the study accounts for many factors, there may still be confounding variables that could affect the results, emphasizing the need for caution in interpreting the data.

Highlights

The study aims to quantify how much our daily habits affect personal life expectancy, focusing on individual actions rather than average life expectancy across the globe.

Researchers analyzed data from three massive datasets, including hundreds of thousands of people, focusing on five primary health factors.

The five primary health factors considered are smoking, physical activity, alcohol consumption, BMI and weight, and diet.

Never smoking is considered the healthiest for the smoking category.

Physical activity is defined as over 30 minutes a day of moderate to vigorous exercise.

Alcohol consumption is defined as moderate consumption or up to 30 grams a day for men and half that for women.

BMI is used as a proxy for weight, with a healthy range defined as between 18.5 and 24.9.

A healthy diet is characterized by high consumption of vegetables, fruits, whole grains, and low intakes of processed meats, sugars, trans fats, and sodium.

The study shows that the risk of cancer death and cardiovascular disease death increases with smoking exposure.

Consuming fewer healthy foods is associated with a higher risk of death by all causes.

Implementing five healthy lifestyle habits significantly improves the odds of avoiding death by all causes.

The study accounts for many possible factors like family history of diseases, age, sex, and menopause.

A healthy lifestyle likely reduces the odds of health-related death, though causation cannot be definitively drawn.

The data shows that women and men doing more healthy habits lowers the odds of all-cause death.

Age eventually takes its toll, regardless of the number of healthy lifestyle factors optimized.

For women at 50 years old, following all five healthy lifestyle factors predicts a 14-year increase in life expectancy.

Men at 50 years old get about 2 years less life expectancy predicted than women.

Life expectancy predictions fall off rapidly as one gets older, possibly due to the limitations of the dataset or the natural progression of age.

Being in the best lifestyle category is associated with over a decade more of life expectancy for individuals aged 50 to 75.

Transcripts

I've always been curious on exactly how

much our daily habits affect our

personal life expectancy so I'm not

talking about the average life

expectancy across the country or across

the globe but how much do my own actions

impact my own life if you wanted to know

that yourself then you're in the right

place because there's this huge study

that came out aiming to quantify how

much of our healthy habits affect our

life expectancy so let's find out how

much my all cheese diet has affected my

life other than make it more

enjoyable these researchers took the

data from three massive data sets

including hundreds of thousands of

people and focus their attention on five

Primary Health factors can you guess

what they are I'll give you a hint

they're really obvious so don't

overthink it post your guess and pause

the video okay here they are one smoking

two physical activity three three

alcohol consumption four BMI and weight

and five diet those are the categories

but what did they consider healthy for

each the researchers put never smoking

as their top tier healthiest for

physical activity it was defined as over

30 minutes a day of moderate to vigorous

exercise alcohol consumption was defined

as moderate consumption or up to 30 gram

a day for men and half that for women

BMI was used as an imperfect proxy for

weight which was defined as anyone

between a BMI of 18.5 and

24.9 finally the most heated topic of

all which surely everyone will have an

opinion on diet which was considered to

be healthy if people were in the top 40%

for consuming vegetables fruits whole

grains polyan saturated fats omega-3

fats and low intakes of processed Meats

sugars trans fats and sodium I realize

this isn't getting into extreme detail

but for the sake of brevity we'll leave

it here because I have a lot to show you

also if you disagree with the

characterizations of healthy from before

that's fine uh we'll be looking over

data when we exclude one of the criteria

and only follow four of these Healthy

Lifestyles as well so focus on that data

and you'll still get some useful

information okay so here's some data but

if it's okay with you I'll just

highlight a few sections because if we

go over all this data I may need a nap

halfway through in general they're

separating the healthiness of each

condition across five groups so the

least healthy to the most healthy take

smoking for example never is The

Benchmark and past is people who used to

smoke but stopped and then the rest are

increasing amounts of cigarettes a day

you'll notice that under cancer deaths

risk increases with smoking exposure so

the higher the number above 1.0 the

greater the risk of cancer death in a

stepwise fashion it increases I think

humans bears and Aliens alike can all

agree that this is pretty expected the

same is also true for cardiovascular

disease deaths and for overall risk of

death on the other hand the died

condition went in the opposite direction

so being in the top one indicates

consuming the least across all of the

previously mentioned Health Foods and

that's why it's called the referrent all

of the others below it are groupings of

people that ate more and more of the

foods mentioned previously now we do not

have the data on how much of each food

that they consumed just that on average

they ate more especially group five so

the risk of death by all cause cancer

deaths and cardiovascular disease deaths

all decreased so they were below 1.0 in

a stepwise fashion

finally how about depending on if people

did all five of these habits to the

highest degree which is category five

there or did none of them which is

category zero there again the more

implementation of these five habits

massively improved odds of avoiding

death by all causes when compared

against people who did none now to be

clear these are associations so it's

always possible that there's some

confounding variable that we aren't

accounting for but the researchers did

account for many possible factors like

family history of diabetes uh

cardiovascular disease cancer age sex

menopause and a few others so while we

still can't draw causation I hope that

the Bears the aliens and the US can

still agree that a healthy lifestyle

likely reduces the odds of health

related

death okay I didn't show you all the

data full disclosure for the reason that

I mentioned earlier remember the whole

nap time and all you're not here to

learn about the healthy habits reducing

odds of death that much is likely

intuitive to you at this point you want

to know how much longer that you'll

actually live well let's look at that in

just a minute first I'd like to

reintroduce the age variable because I

think that this will be interesting to

most look at this data this is the exact

same data that we were just looking at

in relation to all cause mortality with

one two three four or five healthy

lifestyle factors optimized so five is

the best however the data reintroduces

the age variable previously removed so

you see increased age starting at 45 up

to 85 or so the one at the top of the

vertical axis is a standard and that

standard is zero lifestyle factors

optimized so as before showing anything

below one is reduced risk notice how

linear everything is almost always five

is better than four and four is better

than three I feel like I'm teaching a

kid how to count here I I don't mean it

that way the data is just so predictable

that it comes off like I'm saying three

is bigger than two and two is bigger

than one that's right high

five but joking aside you can see that

women and men doing more healthy habits

lowers the OD of all caused death now

the age aspect is unique here because

regardless of the number of Health

lifestyle effects age eventually takes

its toll you can see the risk increase

again around 75 years old in men and a

bit less so in women still risk is still

dramatically lower than doing nothing

pretty neat isn't it okay so enough

about that we want real numbers how much

longer are people predicted to live so

I'm going to be showing you similar data

to before but instead of showing you

mortality risk it will show the

estimated life extension benefit of

doing five 4 3 Etc this isn't a rocket

launch of the healthy lifestyle

intervention you might be interested to

see the impact of each lifestyle Factor

has individually on life expectancy and

how much weight plays a factor alone or

in combination with other factors you'll

have access to that in the full analysis

the extended version of this video if

you're a physionic Insider I'll leave

the link in the description if you're

interested you get access to this plus

all my other analyses and much more that

said what does the overall data show

well as we can see starting at 50 years

old and going all the way to 105 years

old the Blue Line indicates five Health

lifestyle interventions and you can read

read the rest now the vertical axis is

indicating the number of years estimated

to be gained at a particular age so to

give you a few examples for women being

50 years old and following all five

healthy lifestyle factors there is a

14-year predicted increase in life

expectancy however women at 75 years of

age are predicted to only achieve say I

don't know what do you think 10 years is

that fair just cross the 75-year-old

mark up to the blue line and across the

life expectancy increase hopefully you

get the picture oh and this is not

saying that a person will only live 10

or 14 more years this is an addition of

10 to 14 years to the average now I'm

not going to keep detailing isolated

scenarios you can use two fingers and

get the estimate for what you're

interested in but I do have two things

to point out one men get the short end

of the stick men at 50 get about 2 years

less life expectancy again predicted

than women generally although not always

men underperformed compared to women

still that doesn't mean that there isn't

a benefit the benefit is still massive

two notice how the life expectancy

predictions fall off rapidly as one gets

older now part of that may be a function

of the data set used meaning that they

didn't have data in older people than 5

and then again there may be a uh

morbidly good reason for that it may be

that father time gets us all no matter

what we

do but don't despair this is looking at

massive data sets and doesn't keep track

of the exceptions which is where the

Cutting Edge research is trying to make

most of its discoveries and we certainly

know that some people live longer than

105 although this data reports on

averages so to put a bow on this unless

you're continuing with the analysis

through the physionic Insiders being in

the best lifestyle category so that's

normal weight healthy diet never smoked

limited alcohol consumption and

Physically Active is associated with

over a decade more of life expectancy if

you are 50 to about 75 as a woman and

about 70 as a man and think about the

health span benefits too you be more

functional you'll live longer by a

noticeable amount and you'll be able to

watch physionic for longer too I mean

come on what's there not to

love if you'd like some tips on exactly

how to improve in multiple of these

aspects of Health I have a wonderful

video right here for you and of course

the smoking one is pretty simple don't

I'll give that one to you right

now
