Listen to my podcast where I will discuss watching portion distortion in our everyday eating: How many of you have been on the “See food” diet?  We eat what we see.  Managing portion distortion is one of the toughest challenges for many of our clients. Research shows we underestimate what we eat by about 30% We have bigger deals, kitchens, stores, bottles, plates, packages and portions One research study analyzed the size of meals in the cookbook “The Joy of Cooking” in North America versus a comparable book in France.  They found in general the recipes all had bigger portions http://www.healthstandnutrition.com/watching-portion-distortion/
