Author Yuval Hari points out the dramatic increase in obesity in the US, noting that it was rare when he was born in 1979, but has exploded since. He states that obesity doubled between his birth and age 21, and then doubled again in the subsequent 20 years.
“Obesity was extremely low in the year I was born, and it has exploded in my lifetime.”
“Between the year I was born and the year I turned 21, obesity doubled in the United States. And then in the next 20 years, severe obesity doubled again.”
