Take a lap around the table.
Before you grab a plate and jump in the food line, take a look at what is offered. Results of observational research conducted by Dr. Brian Wansink of Cornell University report that this practice is a characteristic shared by thinner people versus those who are overweight. Circle the buffet table and put all of the foods into three categories -- savor, sample, and skip. Take an appropriate portion of the foods you must try, take a taste of those that spark your curiosity, and skip foods that are not special to the occasion.
