Here's a simple trick to lose a few pounds: Keep healthier food around ... and don't eat it. Just let it sit there, looking disapprovingly at the pizza you're gorging on.
You smug motherfucker.
Why? It turns out that just having healthier food on your table makes you a more conscientious eater. According to researchers from Cornell University, even if you don't choose the healthier alternative in front of you, you're still going to make healthier choices than if you didn't have that fruit or salad there at all.
In their study, they went to a school cafeteria over several days and put different side options on the lunch line. On one day they placed sugary meals like applesauce and fruit cocktail on the counter, and on the next there were healthier things like green beans and bananas. Naturally, most of the students ignored the obvious attempt to make them eat better and just chose what they would normally choose.
It's like putting heroin next to an algebra textbook. Which would you choose?
