Establishes a cut-off point, or threshold, to estimate the prevalence (percentage) of the undernourished population in a country expressed in kcal per person per day. Dietary energy requirements differ by gender and age, and for different levels of physical activity. Accordingly, minimum dietary energy requirements, the amount of energy needed for light activity and minimum acceptable weight for attained height, vary by country, and from year to year depending on the gender and age structure of the population. For an entire population, the minimum energy requirement is the weighted average of the minimum energy requirements of the different gender-age groups in the population. Particularly in countries with a high prevalence of undernourishment, a large proportion of the population typically consumes at dietary energy levels close to the cut-off point, making the minimum dietary energy requirement a highly sensitive parameter. In most countries, the new human energy requirement standards have resulted in an overall drop in the amount of food required, and a decline in the prevalence of undernourishment.
