Permanent weight loss requires making one's home a "fat free zone" by removing all unhealthy foods and drinks from cupboards that may lead to temptation. This creates a barrier against regaining lost weight by eating forbidden foods. The author tried this method by throwing away takeout menus and fatty snacks. Though it was difficult due to loving those foods, replacing them with fruits and vegetables caused taste buds to change and weight to reduce steadily over months. Maintaining this lifestyle keeps the weight off permanently rather than risking old habits by reintroducing tempting triggers.
