AI synopsis
What people are saying
Numerous discussions highlighted specific findings from the study, such as the correlation coefficients for BMI among identical twins raised apart being around 0.70 for men and 0.66 for women. Phrases like 'genetic influences on body-mass index are substantial' illustrate a strong recognition of the research's implications. The tone tends to reflect confidence in scientific data, with participants emphasizing the genetic basis of obesity over environmental factors.
The majority of discussions express strong alignment with the study’s conclusions about the genetic influences on BMI.
Participants show high levels of curiosity regarding the implications of the research findings.
Many contributors engage deeply with the data and methodologies discussed, reflecting critical analysis.
The consensus is that this research holds significant implications for understanding obesity and genetic factors.
Abstract in brief
- The study examined the influence of genetics and environment on body mass index (BMI) by analyzing various pairs of identical and fraternal twins, some raised apart and others raised together.
- Findings revealed that genetic factors have a strong impact on BMI, with heritability estimates showing high correlation for identical twins, whether raised apart or together, while childhood environment had minimal influence on their BMI later in life.
- Unique environmental factors, specific to each individual, accounted for about 30% of BMI variance, highlighting the importance of genetics over shared upbringing in determining body weight.

@knicksStan123 @QueerlyAutistic So far, the CDC has identified more than 50 different genes linked to obesity, and there have been multiple studies showing that these genes affect whether or not a human becomes obese, rather than choices in food or exercise Here's a link to one of them https://t.co/XJAWfnWfWc

@Communio13 @Aella_Girl https://t.co/M2mXoPBZkk https://t.co/AYzoE3nWZn https://t.co/DBA1czMbVo There are more, but basically identical twins, even raised apart, end up choosing similar careers, having similar temperaments and even marrying similar wives.
@cremieuxrecueil Back before the obesity epidemic, twins reared apart had pretty similar weight and intelligence. Whatever one asserts, it has to be consistent with increasing obesity, and obesity of people of similar genetic background in different geographies. https://t.co/Lsjkiwdahp

@JimJohnsonSci @JohnSpeakman4 @raphaels7 The higher percentages come from compelling study designs, like twins reared apart. It's hard for me to understand how this design is substantially biased.

The third finding of this study is that neither the shared rearing environment nor correlated environments contributed to variation in the body-mass index. https://t.co/IUe4D149JP
@Jerry_DurhamPT A couple of those studies used both in the systematic review cited. For obesity, when reared apart is compared to other twins raised together and MZ vs DZ twins, we get 66% to 70% heritability of BMI for instance (others I’ve seen say similar) https://t.co/vnlnzjPoAX
@jamieschaf @Leftylockdowns1 Obesity is at least partly genetic. Studies of twins have shown they have similar BMIs even when raised apart. For example https://t.co/cuJOBAmLR6
