Researchers at Georgia State University in Atlanta have shown that group size dramatically affects the number of calories consumed. If you are with one other person, you will eat 35 per cent more calories than if you dine alone. In a group of eight, you're looking at a whopping 90 per cent increase.
Really? If I'm in a group of eight I'm likely to eat twice as much as if I eat alone? That seems spectacularly unlikely. Can someone please do some research for me and report back on whether this is really true? The underlying study here is from 1992, and surely there have been followups since. Thanks!
