- n. the breakdown of more complex substances into simpler ones with release of energy, in living organisms; destructive or downward metabolism; -- a form of metabolism, opposed to
anabolism. See also disassimilation.
from The Century Dictionary and Cyclopedia
- n. In physiology, that phase of metabolism which consists in “a downward series of changes in which complex bodies are broken down with the setting free of energy into simpler and simpler waste bodies” (M. Foster): opposed to anabolism.

NOT getting enough protein is a sure way to destroy muscle and promote catabolism, which is obviously detrimental to any type of fitness program or goal.
As the banana ripens the chlorophyll begins to break down a process called catabolism and the resulting products are concentrated in the banana peel.
As the banana ripens, the chlorophyll begins to break down - a process called catabolism - and the resulting products are concentrated in the banana peel.
This article describes the actual biology of metabolism at a cellular level, which explains just how those processes are carried out. reducing power to construct complex molecules, and perform life functions such as catabolism, in which a cell breaks down complex molecules to yield the chemical energy and reducing power.
Increased catabolism due to these factors can in turn lead to numerous health concerns including cardiovascular disease, diabetes, chronic lung conditions, arthritis, autoimmune diseases, neurodegenerative and neuromuscular diseases, cancer and more.
First, let's examine what increases catabolism, and then we will examine the unique role that adaptogens can play in slowing down the aging process.
Anabolism is a restorative, healing, balancing process, while catabolism is active, degenerative and stressful.
Increasing anabolism to more effectively counteract catabolism is key to the art of graceful aging.
There are two metabolic mechanisms involved in aging that are constantly operating in our body called anabolism and catabolism.
As Ronenn Roubenoff and Carmen Castaneda wrote in a paper titled “Sarcopenia—Understanding the Dynamics of Aging Muscle,” published in The Journal of the American Medical Association, “Sarcopenia is not a disease… but is the backdrop against which the drama of disease is played out: a body already depleted of protein because of aging is less able to withstand the protein catabolism that comes with acute illness or inadequate protein intake.”
