Synopsis (short abstract) This manual presents a practical approach to calculating population energy needs. It is intended for use by economists, planners, and nutritionists in all parts of the world, who are dealing with problems of food supply at a national or regional level. An extensive collection of recent data on basal metabolic rates and energy expenditure of different population groups allows estimates of national energy needs to be derived. These figures allow for desirable changes in body weight and height, and physical activity in children and adults. During the preparation of the manual, discussions with planners allowed refinements to be made to suit their needs, especially in the development of computer modelling techniques. Assumptions are made that the reader is not fully versed in nutrition, nor in the finer physiological aspects of energy balance. The manual does highlight the numerous assumptions that are usually made when the energy needs of a population are calculated. It includes data for applying the methodology should local data not be available. A spreadsheet program and a User Guide are included to facilitate the calculation of requirements. As with the manual, data is supplied if local data is not available.

Human energy requirements
Report of a Joint FAO/WHO/UNU Expert Consultation
2004

Since 1949, FAO has convened groups of experts to evaluate current scientific knowledge in order to define the energy requirements of humans and propose dietary energy recommendations for populations. The World Health Organization (WHO) joined this initiative in the early 1950s, and the United Nations University (UNU) in 1981. New scientific knowledge generated in the 20 years since the last consultation was held prompted the assembly of a new expert consultation to make recommen dations for energy requirements of populations throughout the life cycle. This publication is the report of that consultation, which took place from 17 to 24 October 2001 at FAO headquarters in Rome. The report is not meant merely to describe the energy expenditure and requirements of population groups. It is intended also to be prescriptive in supporting and maintaining health and good nutrition, defining human energy requirements and proposing dietary energy recommendations for populations. The new concepts and recommendations set forth in the report include: calculation of energy requirements for all ages; modification of the requirements and dietary energy recommendations for infants, older children and adolescents; proposals for different requirements for populations with lifestyles that involve different levels of habitual physical activity; reassessment of energy requirements for adults, based on energy expenditure estimates expressed as multiples of basal metabolic rates; classification and recommendations of physical activity levels; an experimental approach for factorial estimates of the energy needs of pregnancy and lactation; and recommendations for additional dietary energy needs in the two last trimesters of pregnancy. The report is accompanied by a CD-ROM software program and instruction manual on calculating population energy requirements and food needs.

The Food and Agriculture Organization of the United Nations (FAO) and the World Health Organization (WHO), in their roles as technical agencies of the United Nations (UN), are charged with providing science-based guidance on food and nutrition to national governments and the international community. The process used to do this involves periodic and systematic reviews of scientific evidence, which often culminates with the convening of joint expert consultations to review the state of s cientific knowledge, deliberate on the issues and translate this knowledge into a definition of requirements and corresponding nutrient-based recommendations. The overall goal of these recommendations is to support health and nutritional well-being of individuals and populations. The topics covered during the recent past include energy, protein and amino acids, fats and oils, most of the vitamins and minerals and carbohydrates, with the objective of providing guidance on nutritional requirements and recommended dietary intakes.The Joint FAO/WHO Expert Consultation on Fats and Fatty Acids in Human Nutrition (hereafter Expert Consultation) was the most recent expert meeting convened, and was held in Geneva from 10 to 14 November 2008. The Expert Consultation was the third to be held on the subject of fats in human nutrition, the first expert consultation on this topic being held in 1977 (FAO, 1978) and the second in 1993 (FAO, 1994).
