Appetite is a complex phenomenon that is influenced by various factors. Understanding the factors that impact your hunger and satiety levels is essential if you are looking to manage your weight, improve overall health, or develop a deeper connection with your body’s natural cues. Let’s take a closer look at the different factors that influence appetite:

  1. Hormones: Ghrelin and leptin are hormones that play a critical role in controlling hunger and satiety levels in the body. These hormones can influence appetite and feelings of hunger or fullness. Ghrelin increases appetite, while leptin decreases appetite. Hormonal imbalances can lead to an increase or decrease in appetite, causing unwanted health consequences.
  2. Emotion & Stress: Emotional states like stress, anxiety, depression, grief, and boredom significantly influence appetite. These emotions can trigger emotional eating or loss of appetite, both of which can have detrimental effects on health. Overeating or undereating can lead to undesirable weight changes, further complicating health issues.
  3. Sleep: Inadequate or poor quality sleep can disrupt hormone regulation, leading to increased ghrelin levels and decreased leptin levels. This hormonal imbalance can result in heightened appetite levels and potentially lead to weight gain. Prioritising 7-9 hours of quality sleep is crucial for hunger hormone regulation.
  4. Medication: Certain medications can increase or decrease appetite levels. It is crucial to be aware of the medication and its side effects.
  5. Medical condition: Certain medical conditions can decrease appetite levels, such as bacterial or viral illnesses, hypothyroidism, cancer, and Parkinson’s disease. On the other hand, hyperthyroidism, Graves’ disease, bulimia, binge eating disorder, hypoglycemia, and diabetes can increase appetite levels.
  6. Exercise: Physical activity affects one’s energy, nutrient needs, and appetite. The type and duration of physical activity can impact appetite after a workout. Regular exercise can regulate appetite hormones and promote a healthy weight.
  7. Meal time: Irregular eating patterns or skipping meals can impact hunger and appetite. It is crucial to stick to regular mealtimes and avoid prolonged fasting periods to regulate hunger hormones.
  8. Age: Age-related changes and differences in metabolism can affect appetite and hunger levels. As individuals age, changes in metabolism and lifestyle can alter hunger signals, making it harder to recognise when we truly need nourishment.

Overall, irregular meal times, age, food choices, and socioeconomic factors significantly influence appetite, creating a complex interplay that affects how and when we feel hungry. Incorporating protein and fibre-rich foods into one’s diet has been shown to promote a feeling of fullness, helping to curb appetite and prevent overeating. The practice of mindful eating, which encourages an awareness of hunger cues and a more thoughtful approach to meals, can help regulate appetite hormones. By paying closer attention to the body’s signals and eating with intention, individuals can better manage their hunger and maintain a healthy relationship with food.
