Sora Shin, assistant professor on the Fralin Biomedical Research Institute at VTC, has been awarded a five-year, $2 million National Institutes of Health grant to look at the mind circuit more likely to be accountable for high-fat food plan overconsumption after a interval of avoiding extremely craved meals.

According to the World Health Organization, greater than a billion folks worldwide are overweight, and the quantity is growing. The main offender contributing to this international public well being disaster: the provision of too many low-cost, appetizing, and calorically dense treats.
