Besides running on treadmill for hours to cut down unnecessary fat from your body, using smaller plates can also be highly effective. Previously, research was conducted to see whether small portions help in reducing fat or not and a new research conducted by the Cornell Food and Brand lab examined all these prior research projects together and found that overall, smaller plates can help reduce consumption under specific conditions, Science reported. After combining all the studies, researchers showed that halving the plate size led to a 30% reduction in amount of food consumed on average. In the case of plates, reducing the diameter by 30% halves the area of the plate and reduces consumption by 30%. The study is published in the Journal of the Association for Consumer Research (ANI).
