The dysgenic trend currently occurring in America has implications for obesity as well. Since intelligence is negatively correlated with obesity, as America’s average IQ decreases, the rates of obesity in our country will increase. This is due to the high correlation between intelligence and obesity. As we continue to allow unfettered immigration into America, the average IQ of the country will decrease, while the amount of people that are overweight and obese will increase.

The ethnic differences in obesity rates lead more credence to what I am saying. As the demographics shift, more people will be overweight or obese due to having a lower IQ. Whites, too, are experiencing this dysgenic effect, as intelligent people of all ethnicities are not reproducing. As more and more genetically less fit individuals continue to have a higher rate of reproduction in comparison to intelligent individuals, this crisis will continue to persist.

Those with lower intelligence have less of an ability to delay gratification, which has a strong genetic component. As more people breed who cannot delay their gratification, the rates of obesity will increase in the country. Of course, the lack of ability to delay gratification comes with a lowered IQ. This is what we see in regards to sex. Those with higher IQs lose their virginities at a later age in comparison to those with lower IQs. Along with the data from Kanazawa that shows that more intelligent people have a lower BMI than those with lower intelligence, this study gives more credence to the theory that those with higher levels of intelligence can better delay their gratification.

JayMan says that there is evidence for an increased genetic load for those with lower IQs, which we can then reason that this also leads to a higher prevalence for obesity in low IQ populations. JayMan then says that many of the genes found to influence obesity seem to operate in the brain and that they have a pleiotropic effect, meaning that multiple genes affect one or more traits. With the increased genetic load comes with an increased chance to have a lower IQ and become obese, as these two things correlate with the lack of ability to delay gratification.

Of course, these problems persist due to modern medicine. With the advent of better medicine, it allowed us to beat diseases that formerly would have been devastating to the population at large. This led to an increase of alleles with negative effects in the population that continue to pass down through the generations. Along with these advances in medical technology, welfare and other government-funded programs also enable those that are less genetically fit. Since intelligence is correlated with ability to care for offspring, as well as r- and K-selected traits, those with lower intelligence exhibit more r-selected traits. This is why America is facing a dysgenic fertility crisis. Welfare props up those with less intelligence, giving them more incentives to breed. They then breed more low IQ children who then will live off of the government. This vicious cycle then continues unfettered due to how America’s dysgenic welfare structure is implemented.

Before the advent of modern technology, those who were less genetically fit didn’t survive to pass on their genes. But, in the modern day with all of our superior technology, this allows the less intelligent to breed when in the past they would have been selected out of the gene pool due to being less biologically fit.

Another variable that is involved with the dysgenic fertility of America is Mexican immigration. With the influx of illegal (and legal) peoples from the South of the Border, this is having both dysgenic effect on both the average intelligence of our country along with the average BMI. The average BMI for the average American male is 28.6In the 1950s, 10 percent of American adults were obese compared to 35 percent of American adults today. Now, this has to do with ability to access food, as well as the effect of the media on children has a huge effect on obesity, due in part to not getting a full nights sleep, as that is correlated with obesity. However, an increase in genetic load, which also comes with a decrease in intelligence, has a lot to do with this as well. The increase in the BMI of the average American has to do with immigration as well. The rates of obesity for different ethnicities in America are as follows: 67.3% for whites, 75.6% for blacks, and 77.9% for ‘Hispanics’. So of course, with more immigration from the South of the Border, the average IQ for America is decreasing while obesity rates are increasing, due mostly to this illegal immigration.

Height and intelligence are both correlated. Ever since the advent of the industrial revolution, we have had an excess surplus of food. As Gina Kolata says in her book Rethinking Thin, an increase in obesity is inevitable. She says this since the increase in genetic height and IQ has occurred, so the increase in obesity follows with it. We need to influence those with higher IQs to have more children. Further, we also need to restrict immigration to only high-skilled immigrants (only when necessary) to reverse this trend that has been occurring since the 1960s. Though, with higher levels of intelligence one can forgo their urges and live a healthier lifestyle due to having higher cognition which leads to a better ability to delay gratification than one with lower intelligence.

Those with higher IQs make better choices on what to eat than those with lower IQs. This is shown in the BMIs of the intelligent and non-intelligent population. As more and more people with lower genotypic IQ come into the country, the quality of life will decrease as will the average intelligence of the country. In turn, the BMI of the average American will increase along with the decrease of our country’s average intelligence. To ameliorate this, we need to have extremely stringent criteria on who we allow into the country. An IQ test, to start, would be a good idea. As those with higher intelligence have less of a genetic load and have less of a chance of becoming obese than one with a lower IQ, the current dysgenic effect that this unfettered immigration is having on America can be lessened.

    The correlation between IQ and obesity is actually fairly weak, (~ -0.25).

    It’s not clear breeding for White Americans is currently dysgenic for IQ.

    Even if it is, that doesn’t necessarily mean obesity is being selected for.

    And even further, population changes due to selection are glacially slow (as per the breeder’s equation). We don’t have to worry about population changes in IQ or obesity due to selection in our lifetimes.

    Immigration of course is quite another matter.

      Well, Kanazawa says that with the extremely small sample (n=141) and extremely limited variance in BMI that the correlation was remarkable and significant.

      Even then, you see the ‘stereotype’ of the southern whites. Most of the countries’ obese states are in the south. Low intelligence is concentrated in the south, regardless of race, so obesity levels are higher in both Southern blacks and whites.

      It’s not clear breeding for White Americans is currently dysgenic for IQ.

      You’re right, blacks do show the sharpest dysgenic decline in IQ in the country. But with lower IQ white women breeding more than higher IQ white women, that is selecting for lower IQ. Since people match by IQ per GST, and lower IQ people breed more than higher IQ people, it’s selecting for lower IQ.

      Even if it is, that doesn’t necessarily mean obesity is being selected for.

      With lower IQ comes with a higher chance of being obese.

      With immigration we do. With more people coming into the country, legally or illegally, the obesity epidemic will continue to get worse. It’s seen already with the ‘Hispanic’ obesity rates (77.2 percent of ‘Hispanic’ women, 78.6 percent for ‘Hispanic’ men. As more of them come here, the rates will continue to increase. I can honestly see the rate for their population reach 90 percent.

    The brain works better on ketones rather than glucose. There is now a strong link between high carb diets and dementia, so called “type 3 diabetes”

      Meh. I’m not a fan of keto diets. Because once you eat some carbs you’re thrown out of ketosis. I advocate for Tim Ferris’ Slow Carb Diet much more than a keto diet, as the SCD is much more sustainable than the keto diet.

      There is now a strong link between high carb diets and dementia, so called “type 3 diabetes”

      Type III Diabetes is Alzheimer’s Disease. Type III Diabetes accurately reflects the fact that Alzheimer’s Disease is a form of diabetes that selectively involves the brain and has molecular and biochemical similarities with Type I and Type II diabetes.

      So long as you stick your personal daily carb tolerance you should not drop out of ketosis. This of course decreases with age.

      There are more superior and sustainable ways to diet. As I said the Slow Carb Diet is much better than keto. The cheat day at the end of the week is better for insulin. Everyone loves a carb refeed. It’s easier on the mind knowing you get one high carb day in the week. It’s like a reward. It’s much superior to keto.
