Bariatric surgery
As part of the pre-operative process, the patient will be placed on a full-liquid, low-carbohydrate diet approximately two weeks before surgery. This diet helps the patient lose weight before the operation, thereby reducing the risk of complications and recovery time. It also reduces liver size, intra-abdominal fat, co-morbidities, and operating time. During this phase, patients must consume only liquids and avoid all solid foods. Their primary sources of energy and protein will be protein shakes, with a recommended fluid intake of 64 ounces per day.
A sample meal plan during this liquid diet phase includes:
- Designer whey protein shake with sublingual vitamin B12
- Isopure 8 oz. Calcium citrate
- 1 ounce of Prostat liquid protein mixed with no-sugar-added juice or water
- Liquefied vegetable soup with protein powder. Calcium citrate
After the surgery, patients can slowly advance their diet to include thicker liquids and soft foods. This may include fat-free soups, skim milk, and protein supplements. Patients should aim to drink 4-6 ounces every hour initially, gradually increasing to 8 ounces per hour, for a total of 64 ounces per day. It is important to sip slowly and keep liquids at room temperature to ease fluid intake.
Overall, the bariatric liquid diet is an essential component of the pre-operative process for bariatric surgery, helping to ensure the safety and success of the procedure, as well as promoting long-term health and weight loss.

Bariatric surgery is a last-resort treatment for obesity, which can also improve or cure related conditions such as arthritis, high blood pressure, and diabetes. Pre-operative weight loss is an important part of preparing for bariatric surgery and achieving the long-term benefits of the procedure.
Around two weeks before surgery, your doctor will advise you to start a full-liquid, low-carbohydrate diet.

It also reduces liver size, intra-abdominal fat, co-morbidities, operating time, recovery time, and post-operative risks.
During this pre-operative liquid diet phase, you must avoid all solid foods. Your main sources of nutrition will be protein shakes and slightly thicker liquids, such as fat-free soups and skim milk. Aim for a fluid intake of 64 ounces per day, sipping slowly and following a schedule. Half of your fluid intake should be water, and it is recommended to avoid drinking through straws. You can add sugar-free flavourings to your water for variety.
In addition to fluids, you can consume sugar-free snacks such as Popsicles or Jell-O. You can also add protein powder to your Jell-O if you make it yourself. It is important to ensure you are getting enough protein, vitamins, and minerals during this phase. Your doctor may also adjust your insulin or diabetic medications if you are taking them.
It is normal to feel full from liquids during this diet and you may not meet your fluid goals initially. However, it is important to stick to the plan and slowly advance your diet as advised by your doctor or nutritionist.
