Understanding the Phases of the Post-Surgery Diet
After weight loss surgery, patients typically follow a phased diet to allow their bodies to adapt gradually to reduced food intake. The diet generally progresses through the following phases:

- Duration: 1-3 days
- Allowed Foods:
- Clear broths (chicken, beef, or vegetable)
- Sugar-free gelatin

- Soft fruits (bananas, avocados)
- Cooked vegetables (well-cooked and soft)

5. Regular Diet Phase
This final phase allows individuals to eat a wider variety of foods, focusing on balanced nutrition.
- Duration: 6 weeks and beyond
