Starvation response in animals (including humans) is a set of adaptive biochemical and physiological changes, triggered by lack of food or extreme weight loss, in which the body seeks to conserve energy by reducing metabolic rate and/or non-resting energy expenditure to prolong survival and preserve body fat and lean mass.
The liver can provide glucose for the first few hours. After that, the body begins to break down fat and protein. The body uses fatty acids as an energy source for muscles but lowers the amount of glucose sent to the brain. Another chemical that comes from fatty acids is glycerol. It can be used as glucose for energy but eventually runs out.
After this time, the damage to muscles and organs can be permanent and can also eventually cause death, if left untreated. Catabolysis is the last metabolic resort for the body to keep itself — particularly the nervous system—functional. Protein stores, especially in muscle tissue, provide the amino acids needed for the process.
Eating carbs with protein, fat, and fiber can help promote more stable blood sugar. How you eat also matters, and eating more slowly and early in the day can prevent blood sugar spikes.
Food energy is chemical energy that animals (including humans) derive from their food to sustain their metabolism, including their muscular activity. [ 1 ] Most animals derive most of their energy from aerobic respiration , namely combining the carbohydrates , fats , and proteins with oxygen from air or dissolved in water . [ 2 ]

Metabolism (/ m ə ˈ t æ b ə l ɪ z ə m /, from Greek: μεταβολή metabolē, "change") is the set of life-sustaining chemical reactions in organisms.The three main functions of metabolism are: the conversion of the energy in food to energy available to run cellular processes; the conversion of food to building blocks of proteins, lipids, nucleic acids, and some carbohydrates; and the ...
There are claims that Devraha Baba lived without food. [citation needed] Some breatharians claim that humans can be sustained solely by prana, the vital life force in Hinduism. According to Ayurveda, sunlight is one of the main sources of prana, and some practitioners believe that it is possible for a person to survive on sunlight alone.
