Study Notes on Motivation and Hunger

Physiological Factors:
- Glucose: Major energy source; low levels trigger hunger.
- Set Point: Body's weight thermostat that affects hunger and metabolism.
- Hypothalamus, hippocampus, pituitary gland involved in hunger regulation.
- Hormones: Ghrelin, orexin, leptin, PYY influence hunger.
- Energy output decreases to help maintain the set point; basal metabolic rate adjusts based on food intake.
Cultural and Situational Factors:
- Emotions (e.g., depression) can affect food choices, leading to high-calorie food consumption.
- Genetic and experiential factors shape food preferences; culture impacts food choice (e.g., spicy food in warm climates).
- Social situations: eating with others increases caloric intake, larger portions lead to more consumption.
- Strategies: Nudging nutritious choices can alter eating patterns (e.g., labeling, portion control).
Obesity: Defined by BMI of 30 or higher. Overweight defined by BMI of 25 or higher.

Adopt a healthy attitude towards weight.
Combine exercise with adequate sleep (7-8 hours) for better metabolism and reduced cravings.
Minimize temptation by shopping when full and limiting unhealthy foods at home.
Maintain simplicity in meals and reduce variety to control intake.
Control portion sizes and consider how food is presented.
Timing meals is crucial for weight management and metabolic health.
Watch out for binge triggers like alcohol and emotions; eat slowly to prevent overeating.
Allow for occasional treats and monitor eating habits to track progress toward health goals.
