Kleiber's plot comparing body size to metabolic rate for a variety of species. [1]Kleiber's law, named after Max Kleiber for his biology work in the early 1930s, states, after many observations that, for a vast number of animals, an animal's Basal Metabolic Rate scales to the 3 ⁄ 4 power of the animal's mass.

[ 1 ] Most animals derive most of their energy from aerobic respiration , namely combining the carbohydrates , fats , and proteins with oxygen from air or dissolved in water . [ 2 ]

On average obese people have a greater energy expenditure than normal weight or thin people and actually have higher basal metabolic rates. [45] [46] This is because it takes more energy to maintain an increased body mass. [47] Obese people also underreport how much food they consume compared to those of normal weight. [48]

Energy intake is measured by the amount of calories consumed from food and fluids. [1] Energy intake is modulated by hunger, which is primarily regulated by the hypothalamus, [1] and choice, which is determined by the sets of brain structures that are responsible for stimulus control (i.e., operant conditioning and classical conditioning) and cognitive control of eating behavior.
In Yemen, 53% of children under five are stunted and 32% are born at low birth weight. [2] Sudan has an underweight prevalence of 41%, and the highest proportion of wasted children in the region at 16%. [2] One percent of households in Sudan consume iodized salt. [2] Iraq has also seen an increase in child underweight since 1990. [2]
