PRE-OP MEAL PLAN & PREPARATION
The purpose of this diet is to help shrink your liver prior to surgery by depleting stored glycogen. How we achieve this is the elimination of processed sugars and foods.
This is the guideline for a pre-op diet based on your BMI. Your surgeon may modify this.
- 30-32 = 2 days clear liquids only
- 33-39 = 5 days of pre op diet and two days of clear liquids
- 40-45 = 2 weeks pre op diet and two days of clear liquids
- 46-50 = 3 weeks pre op diet and two days of clear liquids
- 51-60 = 6 weeks of pre op diet and two days of clear liquid diet
- 61-70 = 8 weeks pre op diet and two days of clear liquid
- Do not smoke 30 days before surgery
- Start taking a probiotic six weeks before surgery or as soon as possible. You want one that has a minimum of 50 billion units, and the more strains, the more effective. Recommended Brand: RAW Probiotics
Follow Pre-Op Diet below:
You may purchase these at any health food store or many grocery stores. Please be sure it contains at least 20 grams of protein per serving. Sugar should be half the grams or less than protein- if you have 20 grams of protein, it should have less than 10 grams of sugar
- 2 – 3 protein shakes per day
- You can eat as many raw or cooked vegetables as you want
- 2 – 4 oz. servings of lean protein (chicken, turkey, fish, lean ground beef)
- 1 – 2 servings of a healthy fat (salad dressing, olive oil, nuts, avocado, olives)
- You can add ½ cup of frozen berries or ½ banana to your protein shake
- You can make your shake with unsweetened vanilla almond milk or coconut milk (no regular milk- too much sugar)
- No bread, rice, pasta, refined grains, sauces with sugar and no dairy (milk, yogurt, cheese)
Since you can have as many veggies, here is a great soup you can make to eat when you are hungry:
Sample Meal Plan:
Breakfast: 1 protein shake
