Excessive food consumption in the world is one of the reasons for increased global warming and increased global burden of diseases. It is necessary to reduce the food consumption immediately to halt further damage to human and planet health and meet global nutrition targets. FAO 2019 statistics indicates that there is nearly 8% increase in per capita consumption of dietary energy in the world between 1997 and 2017. There is more than 50% increase in the adult obesity rate during the same period. Estimated Energy Requirement (EER) of the dietary energy used all over the world for the past several decades is an over estimate. Empirical equations are used for estimating EER. Weight, height and age data are included in the formulation of these equations. Increase in height or weight increases the EER irrespective of the work or learning environment. Increase in EER made people increase food intake, which in turn increased weight. This spiraling pattern of weight increase resulted in obesity, overweight and other non communicable diseases in the children as they become adults. Some of the countries reduced protein intake levels in their national level dietary guidelines . Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed. Dietary Energy is expended from the body through excretory organs or retained as chemical energy in the body. Excreted thermal energy is diffused into the surrounding environment causing global warming. Retained chemical energy is deposited in various organ tissues of the human body resulting in chronic Non Communicable Diseases (NCDs).
