Why Obesity In Women's ?

Why Obesity in Women’s?

Women with severe obesity often report an underlying drive to eat regularly because their brain’s function continues to respond to eat. Food clues even after they have eaten and are no longer hungry, a study says.

The article shows that obese study participants maintained activation in the midbrain, one of the body’s most effective reward centers. The movement in the prefrontal cortex and posterior cingulate cortex significantly changed in the lean group, after eating, but not in the obese group. However, this brain activity dropped among lean participants while continuing in their obese counterparts.

Further, while the appeal of pictured food dropped by 17 percent for lean women after they ate, the severely obese women showed only a 4 percent decline.

In recent studies the obesity compared attitudes and the brain activity of 15 severely obese women (those with a BMI greater than 35) and 15 lean women (those with a BMI under 25).

Their brain activity was measured using functional magnetic resonance imaging (fMRI). After fasting for nine hours, they were asked to rate their level of hunger or fullness and then given a brain scan as they viewed pictures of food.

Again, after eating, the participants went through another battery of hunger/fullness ratings and fMRI scans while being exposed to pictures of food.

The obese women showed sustained “hungry” brain activation, even though they reported the same increase in wealth as their lean counterparts.

According to the CDC, obesity in women aged ≥20 years rose by 33.4% between 2001 and 2014, and from 2015 to 2020 it reached a high of 42.2.%, exceeding the rate in men (36.7%). More women aged 20 to 70 years were obese (36%) than were overweight (30.2%).
