What happened on Memorial Day? Did you have a get together? Was there food, lots of food? Who was there? Did the people who were there make a difference in what you ate and how much you ate?
Did you match what you ate with what others were eating? If they were eating too much, did you eat too much as well? If you adopted the Memorial Day norm of the people you ate with, was it because you wanted to “go along?” Or did you march to the beat of your own drum and stick to the kind of eating that demonstrated your losing weight motivation was still there right by your side?
Social influence research certainly shows that people tend to model the food intake of others. In general, you are likely to eat more when you’re with others who eat a lot and eat less when you’re with people who eat just a little.
If you blew it yesterday and conformed to an eat too much mentality, why don’t you put yesterday’s behavior under the heading of “social influence” and today get back on the horse that threw you.
