Hunger is a weakness that results from the lack of food, coupled with the primal desire to eat. The hypothalamus gland is located at the base of the brain, which plays a role in hunger. Fullness and hunger signals come from the two nerve centers within the hypothalamus that affects eating behavior.
This definition may not really help in understanding hunger. But, from a physiological perspective, it does. However, it does not include the emotional or sensory components that so many of us experience on a regular basis.
Mindful eating helps us to become more aware of what goes on in our bodies when we are hungry or full. We pay attention to how emotions like anxiety, influences our eating patterns.
Real Hunger: Physical hunger is what we mostly identify with. Mindful eating allows us to experience this fully. It shows itself with feelings of emptiness and rumbling of the stomach, accompanied by weakness. Extreme hunger can cause lightheadedness, irritation, or tiredness. You may also have difficulty in concentrating. The primal need here is to feed and nourish the body.
Emotional Hunger: Psychological hunger comes from the desire to eat, followed by no physical signs
that it is necessary. The need iѕ more about eating out of habit; because you are either upset or emotional, or because there is delicious food around you.
