Intermittent fasting is an eating pattern that involves alternating periods of fasting and eating within a specific timeframe. It does not specify which foods to eat but rather focuses on when to eat them. Common fasting methods include the 16/8 method (16 hours of fasting and an 8-hour eating window) and the 5:2 method (5 days of regular eating and 2 days of restricted calorie intake). Intermittent fasting has gained popularity for its potential benefits in weight loss, improved insulin sensitivity, and other health markers.

The GAPS diet may benefit individuals with various conditions related to gut health and mental well-being, including digestive disorders, food sensitivities, autoimmune conditions, allergies, autism spectrum disorders, attention deficit hyperactivity disorder (ADHD), depression, anxiety, and other mental health conditions.
