(FOR WEIGHT LOSS SURGERY 800 – 1000 CALORIES A DAY)

Patients need to follow this diet for the 14 days immediately before the surgery. It will reduce the fat and glycogen stored in your liver, make the liver smaller and allow the surgeon to perform the operation safely.

This diet is ONLY recommended for before surgery and should NOT be followed at any other time as it is too restrictive.

  • Have three meals a day and use the ‘extra’ fruit or yoghurts as deserts or as snacks.
  • Try to vary the foods as much as possible during the fortnight to help make sure you are getting a good range of nutrients. It may be a good idea to start having the multi-vitamin and iron supplement (that you are recommended to take after surgery) while you are on this restricted diet.
  • Do not guess weights – use scales to measure portions accurately.
  • No sugar, cooking oils, margarine, butter, low fat spread, mayonnaise or sauces are allowed.
  • The following drinks and flavourings are allowed freely: Water, tea and coffee (using milk from allowance), low calorie squash.
  • A small amount of the following can be added to food if needed: salt, lemon juice, vinegar, balsamic vinegar, garlic, herbs and spices, pepper, artificial sweeteners
  • Include at least 2 litres (4-5 pints) of fluid a day.
