Do you crave for processed food? Do you love eating french fries, burgers or pizzas? If your answer is yes then you should know that the answer lies in your brain. It's your brain which sends you the signal on what you should eat. A new study by Yale University showed that the human brain values foods which are high in fat and carbohydrates, rather than just fat or carbohydrates. Based on this study, we found that Fats and carbohydrates hijack the body's inbound signal governing the inbound food consumption system. Our body's neuron system group of the neural structure is responsible for motivation, desire, craving for reward — is more likely to chose them, a reason why people feel difficulty in losing or keeping off excess weight, the researchers explained. Surprisingly, foods containing fats and carbohydrates appear to signal their potential caloric loads to the brain via distinct mechanisms. Our study shows that when both nutrients are combined, the brain seems to overestimate the energetic value of the food. A study published in Journal cell Metabolism analyzed data from 206 adults. The participants underwent brain scans while being shown photographs of familiar snacks containing mostly fat, mostly sugar, and a combination of fat and carbohydrates and were allocated a small amount of money to bid on their first-choice food. The results showed that people were craving for foods rich in fats and carbohydrates. The results may also help explain brain-body mechanisms underlying the genetic predisposition for obesity, eating in the absence of hunger, and difficulty losing or keeping off excess weight.
