The evidence is building—fat matters

If your New Year's Resolution was to walk more and eat less, you could be smarter at this time next year.

Auriel Willette and Brandon Klinedinst of Iowa State University discovered people mostly in their 40s and 50s who had higher amounts of fat in their mid-section had worse fluid intelligence as they got older. Greater muscle mass, by contrast, appeared to be a protective factor. These relationships stayed the same even after taking into account chronological age, level of education, and socioeconomic status.

• Adiposity exacerbated cognitive aging.

• Greater muscle mass was protective against cognitive aging.

• The effect of muscle on cognition was more than adiposity.

• Lymphocytes, eosinophils, and basophils may link adiposity to cognitive outcomes.

• Sex-specific mechanisms of action were noted among eosinophils and basophils.

Also, Intermittent fasting could be added to medical school curricula alongside standard advice about healthy diets and exercise.

Percent of body fat

And I quote: "There’s a reason why females have a harder time losing those extra pounds. Nature gave a woman more enzymes to store fat and less to burn it in case she needs to support a developing baby. As a result, women have about 5 percent more body fat than men. A healthy body fat percentage for an 18-year-old girl is between 17 and 30 percent, while a 19-year-old should fall between 19 and 31 percent. Adult females 20 to 39 years should strive for a body fat percentage between 21 and 32 percent. Forty to 59-year-old women should fall within the 23 to 33 percent range, while those 60 years and older should be between 24 and 35 percent." That's sounds better than what I heard at the gym today. My percentage body fat is 32.2 according to that little machine that said I was over the recommended for my age. If I lost what the machine recommended, I'd be receiving"get well" cards in the mail.
