….overall, smaller plates can help reduce consumption under specific conditions. The researchers collated 56 previous research studies examining the effect of smaller plates on consumption. The various studies examined whether smaller plates reduce consumption for a wide variety of conditions: food type, plate-type, portion-size and setting.
After combining all the studies, researchers showed that halving the plate size led to a 30 per cent reduction in amount of food consumed on average. In the case of plates, reducing the diameter by 30 per cent halves the area of the plate and reduces consumption by 30 per cent.
