Overnutrition or hyperalimentation is a form of malnutrition in which nutrients are oversupplied relative to the amounts required for normal growth, development, and metabolism.

The term can refer to:

  • obesity, brought on by general overeating of foods high in caloric content, as well as:
  • the oversupply of a specific nutrient or categories of nutrients, such as mineral or vitamin poisoning, due to excessive intake of dietary supplements or foods high in nutrients (such as liver), or nutritional imbalances caused by various fad diets.

Hyperalimentation may also refers to a state where quantities of food consumed are greater than appropriate.[1] It includes overeating, as well as other routes of administration such as in parenteral nutrition.
