1. metabolism

   Metabolism is a series of chemical reactions that occur within a living organism to maintain life. These processes allow organisms to grow and reproduce, maintain their structures, and respond to their environments. They are divided into two categories: anabolism, which involves the building up of substances, and catabolism, which involves the breaking down of substances. Metabolism is responsible for converting food into energy, converting food and nutrients into building blocks for proteins, lipids, nucleic acids, and some carbohydrates, and the elimination of nitrogenous wastes.

1. Metabolismnoun

   the act or process, by which living tissues or cells take up and convert into their own proper substance the nutritive material brought to them by the blood, or by which they transform their cell protoplasm into simpler substances, which are fitted either for excretion or for some special purpose, as in the manufacture of the digestive ferments. Hence, metabolism may be either constructive (anabolism), or destructive (katabolism)

1. Metabolism

   Metabolism is the set of life-sustaining chemical transformations within the cells of living organisms. These enzyme-catalyzed reactions allow organisms to grow and reproduce, maintain their structures, and respond to their environments. The word metabolism can also refer to all chemical reactions that occur in living organisms, including digestion and the transport of substances into and between different cells, in which case the set of reactions within the cells is called intermediary metabolism or intermediate metabolism. Metabolism is usually divided into two categories. Catabolism breaks down organic matter, for example to harvest energy in cellular respiration. Anabolism uses energy to construct components of cells such as proteins and nucleic acids. The chemical reactions of metabolism are organized into metabolic pathways, in which one chemical is transformed through a series of steps into another chemical, by a sequence of enzymes. Enzymes are crucial to metabolism because they allow organisms to drive desirable reactions that require energy and will not occur by themselves, by coupling them to spontaneous reactions that release energy. As enzymes act as catalysts they allow these reactions to proceed quickly and efficiently. Enzymes also allow the regulation of metabolic pathways in response to changes in the cell's environment or signals from other cells.

   Our findings suggest that insulin resistance could increase risk for Alzheimer’s disease by affecting glucose metabolism in the brain.

   This checklist of 10 reasons your internal thermostat is out of whack can help you get a handle on why you're chronically freezing your butt off. You're too thin Low body weight — defined as a BMI hovering around 18.5 or under — can chill you out for a couple of reasons. First, when you're underweight, you lack an adequate level of body fat to insulate you from cold temperatures, explained Maggie Moon, RD, a Los Angeles – based nutritionist. The other thing is, to maintain that low BMI, you have to reduce your food intake so you likely aren't eating very much at all. Skimping on calories puts the brakes on your metabolism, so you don't create enough body heat. Consider putting on a few pounds by loading up on whole, healthy foods that contain lots of protein, fat, and complex carbohydrates. RELATED : Subtle Signs of Eating Disorders Your Thyroid is out of whack Add cold intolerance to the long list of health issues you can blame on the butterfly-shaped gland in your neck. Always being cold is a telltale sign of hypothyroidism, which means Your Thyroid doesn't secrete enough thyroid hormone.

5. Al Bochi:

   People feel like they have no idea what to eat anymore, they've been listening to all these different food rules -- don't eat carbs, don't eat after seven, eat this to increase Al Bochi metabolism -- and intuitive eating helps Al Bochi unlearn that unhealthy relationship with food and bring enjoyment back to the act of eating.
