How Does Hunger Work in the Body?
Hunger is a complex process involving multiple parts of your body working together. When your body needs more energy, your brain sends signals to make you feel hungry. But what exactly happens? Your stomach is actually the first to detect that you need food. As your stomach empties, stretch receptors send signals to your brain that food is required. At the same time, blood sugar levels begin to drop which is detected by cells in your pancreas and liver. These cells then release hormones like ghrelin and leptin that travel through your bloodstream to your brain. 

Once these hunger signals reach your brain, your hypothalamus interprets them and determines the body needs to eat. The hypothalamus then starts the "hunger cascade" by releasing hormones that create the physical feeling of hunger. These include:
• Ghrelin - stimulates appetite and makes food more desirable. 
• NPY - increases motivation to find and eat food. • MCH - reduces your energy levels, making you feel fatigued and want to rest and eat. 

Over time, as you continue without food, your hunger hormones will increase and spike your hunger to the point you cannot ignore it any longer!  Once you do eat and your stomach expands, signals are again sent to your brain to reduce hunger hormone production and you begin to feel full again.

What is Appetite Control?
It can be a challenge to control your appetite and manage your weight. There are many factors that influence how much you want to eat, from biological hunger signals to environmental cues. Here are some key things to understand about appetite control:

Your hormones play a big role. Hormones like ghrelin and leptin signal to your brain when your body needs food. Stress hormones can also increase cravings. Your gut bacteria produce chemicals that influence hunger and fullness. Food choices matter. High fat and sugary foods tend to stimulate appetite more so than lean proteins and complex carbs. The fiber in fruits and veggies helps you feel full. Highly processed foods lack fiber and nutrients to satisfy you for long.  Your environment cues you to eat. Things like seeing or smelling food, social eating, and large portion sizes can trigger you to consume more calories without you realizing it. Limiting cues can help control appetite. Lifestyle factors count. Things like sleep, activity levels, and even your mood impact appetite. Getting enough sleep, exercising regularly and managing stress can all aid in appetite regulation.


What is the biological mechanism behind food cravings?
Food cravings are complex biological phenomena driven by a combination of physiological and psychological factors. Several biological mechanisms underlie food cravings. Neurotransmitters in the brain are involved. Serotonin and dopamine are associated with mood, pleasure, and motivation. Low levels of these neurotransmitters can result in cravings for high-fat and sugary foods that provide a temporary "feel good" effect when consumed. Endocannabinoids, which are similar to the active compound in cannabis, are also released after eating and may promote subsequent food cravings.  Learned behaviors and psychological factors cannot be ignored. Repeated exposure to certain foods can condition us to associate environmental cues like locations, smells, or sounds with eating. Emotions can also trigger eating as a form of self-medication or distraction.

Is appetite the same as hunger?
While appetite and hunger are often used interchangeably in daily conversation, there are some key differences between the two. Hunger is a physical need for food that arises when your body's energy stores are depleted. Hunger is a basic physiological drive that prompts you to eat in order to satisfy this need. On the other hand, appetite refers to your desire or craving for food. Appetite involves psychological and emotional factors that influence what and how much you want to eat. Appetite goes beyond the basic need for energy and involves factors like the taste, smell, and sight of food, as well as your mood. Hunger is a strong physical need that prompts you to eat almost immediately. When hungry, you typically eat the first available food to satisfy this need. But appetite is more selective - you may have the desire to eat a specific type of food due to psychological factors. For example, you may have an appetite for chocolate without necessarily being hungry. So while appetite and hunger often go hand in hand, they are separate concepts. Hunger is the basic physical need for energy that drives you to consume food. Appetite, on the other hand, involves psychological factors that influence your desire and preferences for certain types of food.
