Weight loss makes you smarter--study

A research conducted by John Gunstad, a psychology professor at Kent State University, and a group of experts from various institutions revealed that losing weight augments memory and other cognitive abilities.

Details of the study
Initially, a memory test among 150 people with an average weight of 300 pounds was endured by the analysts. The participants suffered from problems including high blood pressure, type 2 diabetes, and improper sleep.

Out of 150 respondents, 109 had undergone a bariatric surgery (gastric bypass surgery), while 41 did not have any surgery.

"We've known for a while that diet and exercise may also improve cognition, so it's possible there are several factors that are causing these changes.”--Lead author John Gunstad.

After three months, a second memory test was conducted by the experts.

Researchers found that patients, who had lost 50 pounds during the 12 weeks, were more attentive and had increased cognitive abilities. Besides, the 41 obese patients showed no signs of improvement rather had a minor loss of memory.

Apart from escalating memory, weight loss even solves various health problems like hypertension and diabetes.

"We've known for a while that diet and exercise may also improve cognition, so it's possible there are several factors that are causing these changes,” proclaims the lead author John Gunstad.

Bariatric surgery reduces diabetes
A latest research by the National Bariatric Surgery Registry (NBSR) revealed that undergoing a obesity surgery halves type 2 diabetes and resolves other health problems as well.

Mulling over the data of 8700 operations in UK, the experts unveiled that around two-third of the obese patients suffered from more than two diseases, when they were about to undergo surgery.

Besides, one-third had high blood pressure, over a quarter had diabetes, and nearly a fifth had high cholesterol.

Post the surgery, the patients showed an improvement in their health as they managed to oust 58 percent of excess weight. Around 86 percent of patients managed to overcome diabetes in two years.

"This data shows that not only is UK bariatric surgery safe, but it successfully treats a whole range of diseases - including the rapid resolution of diabetes - yet commissioners continue to ignore the facts,” said Bariatric surgeon Alberic Fiennes, chairman of the NBSR data committee.

Adequate exercise and healthy diet is also pivotal, apart from losing weight, report researchers.
