Establishing Energy Recommendations In contrast to the RDA and AI values for nutrients, the recommendation for energy is not generous.The DRI Committee has determined that the composition of a diet that provides adequate energy and nutrients and reduces the risk of chronic diseases is: o 45-65 percent kcalories from carbohydrate o 20-35 percent kcalories from fat o 10-35 percent kcalories from protein These values are known as Acceptable Macronutrient Distribution Ranges (AMDR).Acceptable Macronutrient Distribution Ranges (AMDR) People don't eat energy directly; they derive energy from foods containing carbohydrate, fat, and protein.Each of these three energy-yielding nutrients contributes to the total energy intake, and those contributions vary in relation to each other.?

Establishing Energy Recommendations
In contrast to the RDA and AI values for nutrients, the recommendation for energy
is not generous. Excess energy cannot be readily excreted and is eventually stored as
body fat. These reserves may be beneficial when food is scarce, but they can also
lead to obesity and its associated health consequences.
Estimated Energy Requirement (EER) The energy recommendation—called the
Estimated Energy Requirement (EER)—represents the average dietary energy intake (kcalories per day) that will maintain energy balance in a person who has a
healthy body weight and level of physical activity. ◆ Balance is key to the energy recommendation. Enough energy is needed to sustain a healthy and active life, but too
much energy can lead to weight gain and obesity. Because any amount in excess of energy needs will result in weight gain, no upper level for energy has been determined.
Acceptable Macronutrient Distribution Ranges (AMDR) People don’t eat
energy directly; they derive energy from foods containing carbohydrate, fat, and
protein. Each of these three energy-yielding nutrients contributes to the total energy
intake, and those contributions vary in relation to each other. The DRI Committee
has determined that the composition of a diet that provides adequate energy and
nutrients and reduces the risk of chronic diseases is:
• 45–65 percent kcalories from carbohydrate
• 20–35 percent kcalories from fat
• 10–35 percent kcalories from protein
These values are known as Acceptable Macronutrient Distribution Ranges
(AMDR).
