taste good，it will．So take a moment before you eat your unpleasant healthy food to remind yourself that you are eating delicious fish and chips．
Our eyes eat first
How your food looks is just as important as how it tastes．Dr．Wansink gave cakes to three groups of people．The cakes were exactly the same but served in different ways．
①Group one got the cake on a nice plate．
②Group two got the cake on a paper plate．
③Group three got the cake on a piece of paper．
Dr．Wansink then asked the people how much they would pay for each cake．
Dr．Wansink then asked the people how much they would pay for each cake．
①Group one who got the cake on a nice plate would pay $1.27．
②Group two who got the cake on a paper plate would pay 76 cents．
③Group three who got the cake on a piece of paper would pay 53 cents．
Take some time to make your healthy food look amazing．Cut your fruit into a flower shape and put your colourful vegetables on nice plates．This works really well for your appetite （胃口）．
Out of sight，out of stomach
Dr．Wansink also found that when people sat at the desk full of snacks，they ate 71% more of snacks a day
than those sitting near a clear table．We eat what we see．As a result，put all the unhealthy food in your fridge．
Hide it and make it really hard to get to．The closer bad food is，the more you eat it．
