Can You Blame the Laziness Gene?
You might think Jack is just plain lazy and Joe is self-disciplined ... but new research suggests that their different activity levels could be down to genetics.
Time Magazine reported on a study carried out at the University of Carolina on mice specially bred according to their activity levels. The difference between the most and least active mice was clear:
Exercise-prone mice put in a good 5 to 8 miles per day (the equivalent of an average man running 40 to 50 miles a day) vs. 0.3 miles per day for inactive mice.
J. Timothy Lightfoot, the kinesiologist who led the study team, said that:
When we used to talk about activity, it was whether or not people decided to be active. Now it's clear that there's an inherent drive as to whether one is active or not active.
But do humans also have the "laziness gene"?
So, it seems that mice have a "laziness gene" - but can we use this to suggest that humans do as well? The researchers emphasise that they focused upon the areas which the mouse genome might share in common with humans - and there are now plans to follow up the study with one looking at men and women.
I expect you can think of families where grandparents, parents and kids are active and fit - and families where all members are very overweight. In the past, we'd probably have put this down to lifestyle factors (if children are brought up on a diet of junk food , they'll probably carry on doing so as teens and adults and pass poor eating habits on to their kids) ... but in the light of this study, it might be worth considering whether there are also genetic factors at work.
Should people with "lazy genes" just give up?
The worst message that readers could take from this research is to assume that if they come from a family of inactive, overweight people, it's not worth even trying. Your genes aren't your destiny - but it's worth being aware that some of us have to work a little bit harder to encourage ourselves to stay active. As the Time article says:
Lightfoot hopes to use his research to help determine which patients may need a bigger boost to get moving -- he thinks that perhaps close supervision by trainers or rewards for exercising will encourage genetic lazybones to get to the gym.
Here's ways you could help yourself to beat the "lazy gene":
- Find some forms of activity which you really enjoy, rather than forcing yourself to continue with an exercise you hate.
- Encourage other family members to be active; if you suspect you're genetically predisposed to be lazy, it's especially important to pass on good habits to your kids.
- Don't judge yourself against others. Some people are naturally gym bunnies, but many of us have to work hard to stay motivated.
Do you suspect that your struggles with your weight are due to hereditary factors? Or does all this talk of a "laziness gene" sound like an excuse for being, well, lazy?

The "laziness gene" should be called the "excuse gene".
ReplyWe people seek for reasons why we don't exercises and why we postpone our activity for tomorrow.
We all must do an effort to strengthen our "motivation gene" and maybe than we will see the results that we constantly seek.
I suppose gay people should just strengthen there straight gene then.
If it's in the genes then it's incredibly hard to fight it, and Laurens statement just goes to show how people look at genetic dispositions "just fight it" really doesn't work.
ReplyThere is no "gay gene", sorry. Every gay person I ever knew had screwed up relationships with mom/dad. It's nurture.
ReplyOr maybe they have a screwed up relationship to mom and dad because mom and dad weren't ready for a gay child. Doesn't almost everyone have a screwed up relationship with mom and dad?
I've never understood why we let things be nature vs. nurture when they're both contributing factors. Genes are predictors but there effects can be lessened, especially in terms of behavior. If Suzy really doesn't like to exercise but her mommy takes her for a walk after dinner every day, she develops new habits that go against her "lazy gene." If little Linda was a track star through her teens, but then becomes pre-med in college, her exercise habits might go out the window, not matter how much of a "gym bunny gene" she has. If little Danny is taught by his parents that they will love him just the way he is, he will hopefully grow up into a stable homosexual young man (as long as he doesn't live in the Bible belt.) Little Charlie, who has the same sexual urges, grows up in a restrictive home that leaves him closeted even as he is about to become the governor of Florida.
ReplyOh yes, you know that all of us hayseeds in the bible belt just hate those gay folks. Give me a break. Sorry to get off topic but I'm tired of people perpetuating stereotypes like that.
ReplyI don't know how many gay people you know, but sexual orientation is not a simple attribute like detached earlobes... (nor is the second order behavior - how one reacts to people with different sexual orientation, which I think deserves much more study than the reasons behind homosexuality - why do so many people detest gay couples?). More to the topic, like being gay, being active is not a simple attribute.
Consider another complex attribute - intelligence. There is a genetic component to intelligence (a chromosome 21 trisomy usually affects cognitive ability, for example). But, the idea of "intelligence" is astonishingly complex, and how someone exhibits intelligence depends on a whole host of things.
I think that the same is true for being willing to exercise. Dr. Lightfoot's research has merit, but from an individual's point of view, it's not very meaningful, unless he can show that in humans, there is a genetic disorder like Down's Syndrome that has a significant and well-defined impact on activity.
By the way, Ali, there is no "University of Carolina". Squabbling in 1691 led to the final division of the Carolina Colony into two royal colonies in 1729. This is pure Tar Heel research.
ReplyBeing a Steve Spurrier fan, there is Carolina and North Carolina!
I quess you already know where USC(w) is :-)
ReplyThank you for bringing in some reality.
ReplyActually, Quito this is not pure Tar Heel research either, UNC Charlotte 49ers.
ReplyThat's funny -- I haven't had that experience at all with the gay folks I know. Just goes to show you that anecdote does not equal evidence.
ReplyCereal and Barry - You both took my comment in the completely wrong direction. I'm not an advocate of the "just fight it" school of thought. Nor do I want to get involved in a nature v. nurture fight.
I simply meant that overcoming laziness is about finding motivation and a routine that is comfortable for each person. Having a genetic marker shouldn't be the excuse for why someone doesn't at least TRY.
ReplyLauren I don't believe I took you out of context. I was trying to make the point that if(and that's a big if)you were genetically predisposed to being inactive then it wouldn't be as simple as just getting motivated or finding a healthy routine since you would be wired to be naturally inactive.
Replyi can honestly say that only about 3 people, including myself, in my family have EVER been to the gym. i'm sure that laziness is partly genetic or chemical; but i do believe that you learn from your family members. i never saw anyone in my family take a walk after a meal until i was in my late teens- even then i still wanted to be home watching tv. it does take more motivation, but i believe that if you're lazy and used to never seeing results, you'll feel way more motivated after a week at the gym and you feel your energy level soar. makes you wanna go almost every day
ReplyGood thing human beings are self-aware creatures that can use logic and judgment to look past predilections! There are times I don't feel like working or cooking or paying attention to my pets -- and maybe that's some other lazy gene rearing its head -- but I understand the necessity of getting things done. Someone who needs exercise but doesn't feel like doing it should be able to reason with themselves in exactly the same way. It needs to be done. End of story.
ReplyAnother reason to support eugenics.
ReplyI'm sorry, I didn't realize we had invented time travel from the beginning of the twentieth century.
ReplyI think I'm inherently lazy (would not move much as a kid) but I got to the point where I loved exercise and would do it a lot. Humans are to complicated to look at it one factor at a time, period
ReplyI think it's interesting to step back and look at the general mindset in which this study and pretty much every study is conducted.
If society was structured differently, if we were traditionally inactive and lounged around, taking life at a slower pace, it would be the "active gene" we'd be discussing here and how "active people" should learn to take life more slowly. We'd be outline steps for slowing down instead of getting active and calling this post "Can you blame the active gene?"
These studies seem kind of obsurd when you can look at them outside of societies conditioning.
ReplyWhether or not genetics are a real factor for being lazy, I am thinking that relating to such an idea (or a fact if proven) will be more abused as just another excuse rather than used as a source of acknowledgement.
ReplyCall me crazy, but given the choice I am not sure if I want to know whether or not I have the lazy genes.
Why does the author assume that inactive people are overweight? Does the study on mice show that inactive mice where also fatter than active mice?
That assumption seems totally displaced and arrogant to me. (By the way, I think that everyone, lean or overweight, can benefit from exercise, that's not my point here.)
ReplyI actually emailed the researchers to ask and the reply back was that both groups were similar weight and they did not find an association between activity (or lack thereof) and weight in the study.
ReplyI am a lazy person but I love fitness. People are clueless but do not research how to fix their problems.
ReplyI'm glad you put in the part about not giving up. If it is proven that there is in fact a "lazy gene" in humans, I could see many people using that as an excuse for not trying to stay active. It may make it more difficult, but it is still important to try to stay active.
ReplyWhy does the author assume that inactive people are overweight?
I hit send comment before I finished....LOL....anyway, yes it was an assumption, based on this study, that there were two weight groups - Buff Joe versus Chubby Jack....in the mice in the study there was no difference in weight between the groups.
ReplyWhy blame anything on your genes? It is useless and foolish to tell yourself you can't do something because "you were made that way." Just go ahead and do it.
Not be able to get fit because of lazy genes? I do not doubt that genetics has some part in your fitness, but it is not a primary indicator. I think this is more of an excuse than an important medical finding.
ReplyGenetics load the gun, but environment pulls the trigger.
I'm not so sure about a "laziness" gene, but even if it did exist, you couldn't blame it for keeping you a couch potato, any more than any more than an obese person who overeats and doesn't exercise can rightfully blame their genetics. My entire immediate family has a weight problem. Both my parents are overweight, and all three of my sisters are obese. I used to be as well (from 1994-2002). Yep, the family tendency was definitely there, but the real reason was that, even though I got exercise, I ate waaay too much food. I'm now 5'5" and under 130 lbs. So genetics might provide an obstacle for some people, but it's not an unsurmountable one.
ReplyThere is a saying, "Argue your limits and they are yours!" Of course we can't all be THE best, but we can all work toward being OUR best. Everyone has obstacles and weaknesses, and everyone has abilities and strengths. What you chose to focus on will reveal much of what you are to yourself.
ReplyI think that genetics being the determining cause of behaviors is far overrated. Just like the other posters who brought up the genetic components of homosexuality, there are definitely genes that may predispose people to various traits, but we can ultimately do whatever we choose to do by consciously altering our behavior.
If there is a "laziness gene", everybody in my family has it. Seriously, my mother never cleans her house and my brother never went to college because he was too lazy to fill out the applications. My sister and I both really hate doing housework for the most part, but we make conscious efforts to keep on top of things so we don't end up living in disaster areas. Our families can definitely teach us a lot about how to act when faced with certain situations. Example: in our house, it was perfectly OK for dishes to pile up in the sink for days. I thought it was strange when I went over to my friend Shannon's house and they never had dirty dishes. She always wondered why we had stacks of dishes at MY house...she had a neatfreak mom and I had a slob mom. Genetics had nothing to do with it; we just had different environments.
That being said, who said lazy people are always fat? My husband's lazy and not fat, I can be lazy and I'm not fat. And there are PLENTY of fat people that are most definitely NOT lazy. It all comes down to behaviors. Some people may just need a little more of a push to get themselves into the gym than others, I guess.
ReplyWhen people talk about the effect of genetics on behaviour they refer to tendency rather then actuality.
For example; there is a genetic tendency towards the abuse of alcohol. People with that gene have a tendency towards developing alcohol abuse patterns, but that doesn't mean that they ever will or that everyone who has those patterns also has the gene.
If there is a laziness gene in humans, which has not even been tested at this stage, then it will only mean that people with it would rather lie in the sun then run ten km. Not that they won't run ten km if they have a reason to do so.
This logic does not apply to the other trait under discussion here, that of homosexuality, because homosexuality is not a behaviour.
