Can You Control Your Metabolism With Your Mind?

Well … maybe . In this intriguing video man , NPR ’s Alix Spiegel talk over the piece of work of Columbia psychologist Alia Crum , whose enquiry evoke that food labels have a placebo result on the mode our bodies respond to food and experience hunger . But to what extent do these results mean that we can think ourselves thin ?

Crum designed an experiment to look into the link between what we call back we ’re eating , how full we feel and how our bodies respond . First , she made some milkshakes . Then , she label each shake as either “ Sensishake : Fat Free , Guilt Free , 104 Calories ” or “ leniency : Decadence You merit , 620 Calorie . ” In reality , all the shakes were around 300 calories . Test subjects were ask to drink in the milkshakes while nurses monitored their lineage horizontal surface of ghrelin , a hormone that increase with hungriness , decreases after a repast , and affects the rate of our metabolism .

“ Crum discovered that those who believe they were drinking the soft shake responded as if their body had eaten three times more , ” explain Spiegel . “ So what hoi polloi believed about their milkshake came true . If they recall it was plump , they feel they ’d eaten more and their digestion was affected . Their ghrelin degree spend three times more . ”

As the NPR video points out , Crum ’s findings suggest that while it may not count as much as what we corrode , how we think about what we eat could play a significant role in how our bodies litigate food for thought . There ’s obviously something very likeable about that , but it warrant a good meter of skepticism . For one thing , Crum ’s sketch evidently lack a command mathematical group – that is , a chemical group of test topic who were not deliberately deceive with either empty words or calorie counts .

The video ’s advice to try “ eat healthy food for thought with an lenient mind-set , ” then , also fall flavorless – especially when you consider that none of the tryout subjects have sex i ) the nutritionary visibility of what they were eat up , or ii ) to come near the meal with any mindset but the one they were tricked into adopting . The test was examining a placebo effect based on deception – not a witting one establish on knowing visual image , or any other deliberate mind - soundbox technique .

It ’s still a entrancing first feel at how our beliefs could affect our physiology , but , as Crum herself says , more tests need to be conducted .
