Diet Revolution Completed: Low-Carb Wins Out Over Low-Fat in National Study

A national health study has found that diets low in carbohydrates, complimented by moderate amounts of fat, are better for you than the low-fat diet that doctors and government authorities have recommended for decades.

A national health study has found that diets low in carbohydrates, complimented by moderate amounts of fat, are better for you than the low-fat diet that doctors and government authorities have recommended for decades. At the end of a year-long trial in which a racially diverse set of 150 men and women were asked to either obey a low-carb or low-fat diet, researchers found that those in the low-carb group were significantly healthier:


"[P]eople in the low-carbohydrate group had lost about eight pounds more on average than those in the low-fat group. They had significantly greater reductions in body fat than the low-fat group, and improvements in lean muscle mass — even though neither group changed their levels of physical activity. While the low-fat group did lose weight, they appeared to lose more muscle than fat."

The results are especially encouraging because neither group was asked to reduce the amount of calories it consumed, a task which often trips people up who are attempting a new diet. Individuals in the low-carb group saw inflammation and triglyceride metrics plunge while those of the low-fat dieters remained constant. 

"[T]hose on the low-carbohydrate diet ultimately did so well that they managed to lower their Framingham risk scores, which calculate the likelihood of a heart attack within the next 10 years. The low-fat group on average had no improvement in their scores."

As health and nutrition author Johnny Bowden explained in his 2012 interview with Big Think, processed carbohydrates are perhaps the biggest fad diet ever, taking the long view of human agriculture, because our bodies learned to perform well without them for hundreds of thousands of years:

Do you have a self-actualized personality? Maslow revisited

Rediscovering the principles of self-actualisation might be just the tonic that the modern world is crying out for.

Personal Growth

Abraham Maslow was the 20th-century American psychologist best-known for explaining motivation through his hierarchy of needs, which he represented in a pyramid. At the base, our physiological needs include food, water, warmth and rest.

Scientists reactivate cells from 28,000-year-old woolly mammoth

"I was so moved when I saw the cells stir," said 90-year-old study co-author Akira Iritani. "I'd been hoping for this for 20 years."

Yamagata et al.
Surprising Science
  • The team managed to stimulate nucleus-like structures to perform some biological processes, but not cell division.
  • Unless better technology and DNA samples emerge in the future, it's unlikely that scientists will be able to clone a woolly mammoth.
  • Still, studying the DNA of woolly mammoths provides valuable insights into the genetic adaptations that allowed them to survive in unique environments.

Believe in soulmates? You're more likely to 'ghost' romantic partners.

Does believing in true love make people act like jerks?

Sex & Relationships
  • Ghosting, or cutting off all contact suddenly with a romantic partner, is not nice.
  • Growth-oriented people (who think relationships are made, not born) do not appreciate it.
  • Destiny-oriented people (who believe in soulmates) are more likely to be okay with ghosting.
