Appetite Changes

What are appetite changes?

Appetite changes refer to a noticeable shift in how hungry or full you feel — either losing interest in food entirely, or finding yourself eating far more than usual without feeling satisfied. This symptom often comes alongside fatigue, mood changes, or gut discomfort, and can significantly affect energy levels and daily life.

How to know if appetite changes are chronic

• Lasting more than 4 weeks without a clear cause (illness, medication)
• Accompanied by unintentional weight loss or gain
• Coming alongside persistent fatigue, low mood, or digestive issues
• Interfering with your ability to maintain nutrition and daily function

Appetite changes can be associated with the following conditions:

• Depression
• Chronic Fatigue Syndrome
• Mast Cell Activation Syndrome (MCAS)
• Food Sensitivities
• IBS

Can brain retraining help with appetite changes?

The gut and brain are intimately connected via the vagus nerve. When the nervous system is dysregulated, it can profoundly affect hunger cues, digestion, and relationship with food. Re-origin’s brain retraining program addresses the root nervous system patterns that drive many appetite disruptions, helping the body return to a more regulated, balanced state.
