However, the body can selectively decide which cells break down protein and which do not. [citation needed] About 2–3 g of protein must be broken down to synthesize 1 g of glucose; about 20–30 g of protein is broken down each day to make 10 g of glucose to keep the brain alive. However, to conserve protein, this number may decrease the ...
Phase two: Phase two can last for weeks at a time. In this phase, the body mainly uses stored fat for energy. The breakdown occurs in the liver and turns fat into ketones. After fasting for one week, the brain will use these ketones and any available glucose. Using ketones lowers the need for glucose, and the body slows the breakdown of proteins.
The body uses resources derived from the environment for metabolism, for reproduction, and for repair and maintenance, and the body must compromise when there is a finite supply of resources. The theory states that this compromise causes the body to reallocate energy to the repair function that causes the body to gradually deteriorate with age. [2]

The recommended dietary allowance (RDA) for the average adult is 0.8 grams of protein per kilogram of body weight (or about 10% and 35% of your total calories from protein). But that’s for a ...
People seem obsessed with protein nowadays, but certain age groups need to focus on it more than others. Your protein needs change as you get older. Here’s how much you should be eating at every age
Strength-training athletes may increase their daily protein intake to a maximum of 1.4–1.8 g per kg body weight to enhance muscle protein synthesis, or to make up for the loss of amino acid oxidation during exercise. Many athletes maintain a high-protein diet as part of their training. In fact, some athletes who specialize in anaerobic sports ...
It is possible with protein combinations of two incomplete protein sources (e.g., rice and beans) to make a complete protein source, and characteristic combinations are the basis of distinct cultural cooking traditions. However, complementary sources of protein do not need to be eaten at the same meal to be used together by the body. [44]
