Obesity & Memory – As per the recent study conducted by the University of Cambridge, people who suffer from obesity have a poor memory which includes recalling what meal they had or which people they met. According to the research, people who have BMI above 30, falls in the category of obesity. A test called Treasure-Hunt Task, of 50 participants was conducted to support this study. The old and recently conducted study indicates that the poor performance of the people can be the result of their obesity. However, in order to understand the link between memory and weight, more and more studies should be conducted.

Obesity Memory Relation between obesity and bad memory

People who are obese have a worse memory than their thinner friends, a small study shows.
Tests on 50 people showed being overweight was linked to worse “episodic memory” or the ability to remember past experiences.

Obesity linked to ‘worse memory’

The study in the Quarterly Journal of Experimental Psychology argues that a less vivid memory of recent meals may lead to overeating.

However, other aspects of memory – such as general knowledge – were unaffected.
Tests on rats have previously shown that with burgeoning waistlines come poorer performances in memory tests, but the evidence in humans has been mixed.

The latest experiments looked at episodic memory – the video tape in your mind – that remembers the smell of a cup of coffee or the feel of holding someone’s hand.

Fifty people with a Body Mass Index (BMI) ranging from 18 (healthy) to 51 (very obese) took part in a memory test – a bit like doing a treasure hunt on your own.

They had to “hide” objects at different times and on different scenes displayed on a computer screen.
They were later asked to recall what they had hidden, when and where.

The results showed obese people’s scores were 15% lower than thinner people.
