What does the diet look like after bariatric surgery?

Medcasts editorial team

Standard post-op diet progression (varies by program):

• Day 0–1: clear liquids only. • Day 2–7: full liquids (protein shakes, broths). • Week 2: pureed foods. • Week 3–4: soft foods. • Week 4–6: solid foods, small portions, slow eating. • Long-term: 60–80g protein/day, hydration ≥2L/day, vitamin/mineral supplementation, structured meals.

Total volume per meal post-op is small — typically 1/2 to 1 cup. Eating beyond fullness causes discomfort.

Protein priority is real: muscle loss is the biggest avoidable mistake. Whey or plant-based protein supplements help most patients hit their target.

Dietitian engagement for the first 12 months is highly correlated with long-term success.

Methodology and editorial standards

Answers are written by the Medcasts editorial team and updated when prices, guidelines or visa rules change.

  1. Hospital data. Hospital details are compiled from public sources and hospital websites. Accreditation (JCI, NABH and others) is shown where we hold a record of it. Always ask the hospital for its current certificate.
  2. Doctor credentials. Qualifications, specialty and bio come from the doctor's hospital profile. Licence is checked against the national medical-council register only where the profile shows a "Licence verified" badge with a date.
  3. Prices. Price ranges are indicative, compiled from hospital price lists and packages and shown with the date last updated. The hospital's written quote is what you pay against.
  4. Clinical text. Written by the Medcasts editorial team from published clinical sources. Unless a named reviewer is shown on the page, it has not been reviewed by a doctor.
  5. Independence. Hospitals cannot pay to change their position on our pages.
