According to CalorieLab, research at Scripp’s Research Institute in Florida found that with rats, high-fat and high-calorie foods affect the brain’s pleasure centers much like cocaine does and are similarly addictive. They also noted that, over time, it took more and more of this type of food to get that once-easy high. Rats wouldn’t even stop when shocks were given while they ate these foods.
There’s no doubt that high-fat and high-calorie foods can be hard to pass up. Again, moderation and knowing ourselves and our triggers is our best defense.
