About the Article

The information in this article was provided by the Obesity Society on November 5, 2015 and recounts a research study, that discovered for the first time, the interaction of two gene variants, FTO and DRD2, that can alter the responses in the human brain, when the participants of the study looked at pictures of high-calorie foods of fats and sugars and compared them to pictures of low-calorie foods. Also, by looking at these pictures of high and low-calorie foods, these two gene variants can influence the brain’s reward system. These brain responses could be used to develop a treatment for obesity and for overweight people possibly sometime in the future.

Critic's Review

The author of this article, Dr. Tony Goldstone, is a registered MD and PhD of Consultant Endocrinologists, who works at the Imperial College of London. Goldstone and his team used strong, scientific, evidenced-based knowledge and support from the experiments they conducted because they were able to physically see the results of their study by utilizing the fMRI scanners, and by testing the test subject’s DNA for susceptibilities in the FTO and DRD2 gene variants. Ultimately, these measures have proven their results conclusive and noteworthy of a credible, breakthrough discovery in the world of obesity.

This study was a well written article, published on the ScienceDaily website, and was provided from materials by the Obesity Society, a society that researches material on obesity in people and the causes and effects of obesity.
