Everybody has their weakness when it comes to unhealthy food. Mine is salted corn chips and top quality ice cream. I could literally sit there and eat a whole tub of ice cream or a whole packet of corn chips in one sitting. So I have avoided these foods. It turns out their is some science behind why these types of foods are addictive. They induce “hyperphagia” or abnormally increased appetite. It’s like you literally can’t stop eating:
Summary – Experimental groups of rats were fed either sugar (sucrose), fat (corn oil), or a sugar-fat mixture. The sugar-fat group displayed a robust hyperphagia (abnormally increased appetite) of greater than 36% compared with control and greater than that observed in the fat group but not in the sugar group. The sugar-fat group selected more calories from the option than the other two experimental groups. Body weight gains were also greater in the sugar-fat group…In other words consuming a sugar/fat mixture increased appetite to the point where the rats consumed more calories. In other words they couldn’t stop eating.
Summary – …the current study found that highly processed foods, with added amounts of fat and/or refined carbohydrates (e.g., sugar, white flour), were most likely to be associated with behavioral indicators of addictive-like eating. Additionally, foods with high GL [glycemic load)] were especially related to addictive-like eating problems for individuals endorsing elevated symptoms of “food addiction.”
Summary – …Thus, it can be concluded that the combination of fat and carbohydrates is a major molecular determinant of potato chips [and corn chips!] triggering hedonic hyperphagia.
So the next time your thinking of “trying” some crisps, corn chips, or doughnuts at a social gathering bear in mind the above research. Sometimes it literally not possible for you to stop eating these high fat + Sugar/refined carb foods. They will derail you in one foul swoop!
