Do Your Genes Make You Lazy?

Do Your Genes Make You Lazy?

Nabasa nyo na ba eto?

If you’ve ever had a hard time getting motivated to go to the gym or get off the couch and head outside for a jog, it could be your genetics.

 

According to a new study in the American Journal of Physiology: Regulatory, Integrative and Comparative Physiology, a team of Missouri researchers were able to selectively breed rats that had either an active or lazy disposition.



 

“We have shown that it is possible to be genetically predisposed to being lazy,” said study co-author Frank Boothof the University of Missouri in a statement. “This could be an important step in identifying additional causes for obesity in humans, especially considering dramatic increases in childhood obesity in the United States.

 

“It would be very useful to know if a person is genetically predisposed to having a lack of motivation to exercise, because that could potentially make them more likely to grow obese,” Booth added.

 

To select for one of the two dispositions, the team put rats in enclosures with exercise wheels and recorded how much each rat willingly ran on their wheel over the course of a six-day period. The researchers then selectively bred the top 26 most active with each other and did the same for the 26 laziest. After 10 generations of breeding, they found the more active rats chose to run 10 times more than the descendents of “lazy” rats.

 

The researchers also performed a biological and genetic analysis of each line of rats. They examined the levels of mitochondria in the rats’ muscle cells, compared body types, and conducted an RNA analysis of each rat.

 

“While we found minor differences in the body composition and levels of mitochondria in muscle cells of the rats, the most important thing we identified were the genetic differences between the two lines of rats,” said study co-author Michael Roberts, Professor of Animal Science and Joint Professor of Biochemistry at MU.

 

“Out of more than 17,000 different genes in one part of the brain, we identified 36 genes that may play a role in predisposition to physical activity motivation.”

 

The results of the study could have a significant impact, especially for the 97 percent of American adults studies show get less than 30 minutes of exercise a day – the minimum recommended by federal guidelines.

 

According to the researchers, they plan on continuing their work to identify the effects each gene has on the motivation to exercise.

Tingin ko nga nasa genes din.

Kasi kung ang genetic makeup mo is tabain ka... tendency is kumain ka ng kumain.... now the motivation comes into play if you are disciplined to self regulate what you eat. parang lifestyle na din nung tao.

Pag ang genetic make up mo naman is payat-in ka. tendency is posibleng mataas ang metabolism mo. either you work a lot or get stressed with work .

Just an opinion lang po.

I really don't believe na kung payatin yung buong pamilya necessarily means mataas ang metabolism.

First, kung payatin ka either yung pamilya mo ay hinde mahilig kumain ng marami o kumain ng sobrang sarap na pagkain, kulang ang calories na kinakain mo, does not like to exercise.

Example: Payat karamihan ng mga informal settler not because they have good genes, but rather they can't eat.

Yet here we are "going to the gym to get a poor man's body." (quoted from snickers commercial)

Believe me, if you know real good food and you have the money, you won't be thin.

Sobrang kokonti lang na individuals ang kilala ko na totoong genetically and metabolically gifted and even they are prone to getting fat once they age. They are not thin but rather more muscled.

I've only seen a few with true increased consumptive metabolism or catabolism associated with diseases
a. Cushing's disease
b. Pheochromocytoma
c. Hyperthyroidism

Remember, metabolism is both anabolic (building) and catabolic (breaking). If you have an unusually slow or fast metabolism, you are probably sick.

Hmmm.. come to think of it. I would like to believe that it's also in the genes. may mga tao kasi na since they are gifted di agad sila tumataba. meron naman iba tabain.
