Studies show that when we are offered larger portions, we eat more—30% more. These colossal portion sizes fool our brains and we don’t perceive that we ate more so we don’t compensate by eating less later on. To make matters worse, people are eating a lot more food at a time when less than half (48%) of all adults meet physical activity guidelines and less than 3 in 10 high school students get the recommended 60 minutes or more of physical activity every day.
