Making the Pre-Op Diet Clearer

You should have two or three protein shakes daily and all the salads (with fat free dressing), NON-starchy vegetables (e.g. carrots, celery, zucchini, broccoli, cauliflower, radishes, onions), and approved soups (e.g. tomato basil, sacred heart, egg roll) that you want.
You must be sure to count the meat or lean protein that you add to the soup – 6 oz daily for women and 8 oz daily for men. You can have unlimited sugar-free popsicles, sugar-free JELL-O, Powerade Zero, teas, broths, and zero calorie flavored waters. During the clear liquids diet, you can have no sugar added juices that are diluted, sugar-free popsicles, sugar-free JELL-O, teas, broths, zero calorie flavored waters, etc. Remember that surgery day counts as the third day of the clear liquids diet.

A good exercise plan will include aerobic or cardio exercise, which gets the heart rate up gradually, resistance or strength training, and flexibility or stretching. Before you start any exercise regimen, make sure to get approval from your doctor at home.

Protein Shakes

You should have two or three protein shakes per day. Please be sure each drink contains at least 15 to 20 grams of protein per serving. The amount of sugar should be less than half the amount of grams of protein. For example, if the drink has 20 grams of protein, it should have less than 10 grams of sugar or carbs.

You can make your own protein shakes with unsweetened or lite vanilla almond milk, lite soy milk, or lite rice milk. Do not use regular milk, as it has too much sugar. You can use professionally prepared protein shakes if they meet the same requirements for grams of protein, calories, sugars, etc.

Lean Protein

You should have two servings of 3 to 4 oz of a lean protein per day (e.g. chicken, turkey, fish, salmon, shrimp, scallops, 2 eggs, tofu, 1/2 cup of beans – vegetarians can substitute cooked beans or legumes for lean meats).

Healthy Fat

You should have one or two servings of a healthy fat per day (e.g. salad dressing, olive oil, olives). Use salad dressings sparingly. Dilute them with water or skim milk.

Unlimited Non-Starchy Vegetables

You can eat as many raw or cooked non-starchy vegetables as you want (all non-starchy vegetables are included except peas and corn).

Unlimited Vegetable Soup

You can have as much Sacred Heart Soup as you want, but you need to keep track of the amount of meat or lean protein added to the soup, as that counts toward your daily lean protein allowance.

Unlimited Salads

You can have as much salad as you want, but you need to use salad dressings sparingly.

Absolutely NO bread, rice, pasta, potatoes, sweet potatoes, yams, cereals, oatmeal, popcorn, refined grains, corn, peas, or sauces with sugar.

Three days before surgery

Count surgery day as day three (if you are having surgery on the 5th, you would begin this on the 3rd).

After all foods are done for the day, take a good laxative, any brand that you choose. It is OK to repeat the laxative dose one time but remember that laxatives can take up to 24-48 hours to kick in so follow the instructions on the packaging. Sip fluids and you will be starting on the clear liquids only tomorrow.
