Hunger.

When calculating the energy value of a food item like a peanut, we typically estimate the physiologic energy value, which represents the amount of energy that can be metabolized and used by the body. This accounts for factors such as digestibility and absorption, providing a more accurate representation of the energy available to the body from the food.
It is because of acidity
"Feeling" can mean, among other things, "sensation" or "emotion". Hunger is a sensation, but not an emotion.
When Brian yells "I'm hungry" in the book Hatchet by Gary Paulsen, he realizes that he needs to find food to survive in the wilderness. This moment prompts him to take action and learn how to find food and sustain himself using the resources around him.

Hunger
The sensation of hunger is primarily alerted by a complex interplay of hormonal signals and neural pathways. When the stomach is empty, it releases ghrelin, a hormone that signals the brain to initiate feelings of hunger. Additionally, the hypothalamus processes these signals, alongside other factors like blood sugar levels, to create the conscious awareness of needing food. This intricate system ensures that the body maintains its energy balance and prompts us to seek nourishment.
The term for the sensation of fullness is "satiety." It refers to the feeling of being satisfied or having enough food in the stomach, leading to a decreased desire to eat. Satiety is influenced by various factors, including hormonal signals, the type of food consumed, and the volume of food ingested.
Physiologic activity in the liver involves processes such as detoxification, metabolism of nutrients, and production of bile. The spleen plays a role in filtering blood, producing antibodies, and storing red blood cells. In the colon, physiologic activity includes absorption of water and electrolytes, formation of feces, and hosting a large population of beneficial bacteria for digestion.
Physiologic population density refers to the number of individuals a habitat can support based on available resources like food, water, and living space. It represents the maximum number of individuals that can live sustainably in an environment without depleting resources or causing environmental degradation.

Gerbils may exhibit increased activity levels and speed when food is scarce due to heightened survival instincts. The lack of food prompts them to forage more actively, seeking out resources, which can lead to faster movements. This behavior is driven by their natural adaptation to survive in arid environments where food availability can be unpredictable. Consequently, the urgency to find food can enhance their overall agility and speed.
