A sedentary lifestyle and a sugary diet are more harmful to men

A new study from the University of Missouri School of Medicine is the first evidence in humans that short-term lifestyle changes can disrupt the response to insulin in the blood vessels. It’s also the first study to show that men and women react differently to these changes.

Vascular insulin resistance is a feature of obesity and type 2 diabetes that contributes to vascular disease. Researchers examined vascular insulin resistance in 36 healthy young men and women by exposing them to low physical activity for 10 days and reducing their number of steps from 10,000 to 5,000 steps per day. Participants also increased their intake of sugary drinks to six cans of soda per day.

“We know that the incidence of insulin resistance and cardiovascular disease is lower in premenopausal women than in men, but we wanted to see how men and women react to decreased physical activity and increased sugar in their diet over a short period of time,” Camila Manrique Acevedo, MDAssistant Professor of Medicine.

The results showed that a sedentary lifestyle and high intake of sugar caused lower insulin-stimulated leg blood flow and a decrease in a protein called adrobin, which regulates insulin sensitivity and is an important biomarker of cardiovascular disease.

“These findings underscore the sex-related difference in the development of vascular insulin resistance caused by the adoption of a high-sugar, low-exercise lifestyle,” said Manrique Acevedo. “To our knowledge, this is the first evidence in humans that vascular insulin resistance can result from reversible short-term changes in lifestyle, and it is the first documentation of sex-related differences in the development of vascular insulin resistance in association with changes in adrobin levels.”

Manrique Acevedo said she would then like to study how long it takes to reverse these vascular and metabolic changes and to fully assess the effect of sex on the development of insulin resistance in the blood vessels.
