Pre-op Bariatric Meal Plan Overview

This pre-op Bariatric meal plan will play a key role in the outcome of your Bariatric surgery for weight loss. It will keep your health in good shape and further prepare your body for the upcoming changes in functioning caused by the surgery.

We all know that Bariatric surgery can lead to specific changes in the functioning and performance of our digestive systems. Hence, we must be careful when following this pre-op bariatric meal plan.

What is a Pre-op Bariatric meal plan

A pre-op bariatric meal plan must include all the macronutrients in the prescribed limits (speak to your surgeon or health consultant in this regard). Generally, the diet allows you to consume 100 grams of carbohydrates daily.

Besides, your diet must be low in fats and moderate in terms of proteins. So, the daily calorie intake must not exceed 1000-1200 calories per day (depending on your age, weight, and health condition).

Why do you need to follow a pre-op bariatric meal plan?

Before proceeding with the Bariatric surgery, you must follow a disciplined calorie-controlled diet. Eventually, this will cause the liver to contract in size, and you can then reduce the chances of any severe complications during the surgery.

If your body mass index (BMI) is more than 35-40 kg/meter square, your liver will most likely gain a big shape due to the high glycogen stores. This may create certain complications during the surgery process.

So, going along with the Pre-op bariatric meal plan is highly recommended. Additionally, you must talk to your surgeon and read the following guidelines and instructions before proceeding with this printable Pre-op bariatric meal plan.
