6 Month Pre-Op Diet: Nutrition Guidelines to Follow Before Weight Loss Surgery

Preparing for Weight Loss Surgery: The Importance of the Pre-Op Diet

For those considering weight loss surgery, the 6 months leading up to the procedure are crucial preparation time. Following the prescribed pre-op diet helps set the stage for better surgical outcomes and long-term weight management success.

The pre-surgery diet helps shrink the liver, reduce fat around organs, and get the body accustomed to the drastic dietary changes that come post-op. Committing to the pre-op plan takes dedication, but is a vital component for safety and results.

Understanding Weight Loss Surgery Options

The most common types of weight loss (bariatric) surgery include:

• Gastric sleeve - Removes 70-80% of the stomach by stapling, creating a banana-shaped pouch.
• Gastric bypass - Divides the stomach into two sections and reroutes intestines.
• Lap band - Places an adjustable band around the top of the stomach.
• Duodenal switch - Removes 70% of the stomach and reroutes intestines.

Each surgery type works by restricting food intake and/or malabsorption of calories. The pre-op diet needs to be followed regardless of which procedure you plan to undergo.

Benefits of the Pre-Surgery Diet

Sticking to the prescribed diet for 6 months before surgery provides many benefits:

Liver Shrinkage

The pre-op diet helps decrease fat deposits in the liver, allowing it to shrink down. This gives the surgeon clearer access and reduces risks during the procedure.

Weight Loss

Losing weight prior to surgery through diet makes the procedure easier and safer. There are lower complication risks and reduced recovery times.

Improved Surgery Outcomes

Patients who complete the pre-op diet as recommended have better weight loss results long-term. The pre-surgery habits pave the way for continued success.

Lifestyle Preparation

The pre-op period helps you practice the drastic dietary changes needed post-surgery. You’ll be prepared for your new way of eating.

Committing fully to the pre-surgery diet gives you the best chance for safe, effective, long-lasting weight loss.

Nutrition Guidelines for the 6 Month Pre-Op Diet

The nutrition rules for the weight loss surgery pre-op diet focus on high protein, low sugar, and small portions. Here are the key guidelines:

High Protein Intake

Getting 60-100 grams of protein daily preserves lean muscle mass as you lose weight. Good protein sources include lean meat, eggs, Greek yogurt, protein powder, beans, and nuts.

64 oz Fluid Minimum

Drink at least 64 oz of calorie-free, non-carbonated fluids like water, unsweetened tea, and sugar-free beverages. Proper hydration is essential pre and post-op.

Low Fat and Low Sugar

Limit high fat foods, added sugars, sweets, soda, juice, and caloric beverages which provide empty calories without nutrition.

5 Small Meals/Snacks Daily

Eat 5-6 small, portion-controlled meals and snacks each day. This prepares you for the smaller gastric capacity post-surgery.

Vegetable Emphasis

Fill half your plate with non-starchy vegetables like broccoli, spinach, peppers, and greens to boost nutrition and fiber.

64oz Protein Minimum

Get at least 64 grams of protein daily from lean poultry, fish, Greek yogurt, protein shakes, beans and nuts. Protein intake will be key post-op.

No Alcohol

Avoid all alcohol, which provides empty calories and can damage the liver you need to heal after surgery.

Following these pre-op diet guidelines sets you up for the new way of eating required for success after bariatric surgery.

To help you understand what a typical day on the pre-surgery diet looks like, here is a sample meal plan:

Breakfast

• 2 scrambled eggs
• 1⁄2 cup black beans
• 1⁄2 cup mixed berries

Morning Snack

• 1⁄4 cup cottage cheese
• 5-6 whole unsalted almonds

Lunch

• 4 ounces grilled chicken

This provides balanced nutrition focused on lean protein, vegetables, healthy fats, and hydration to support you pre-surgery.

Exercise Recommendations Before Weight Loss Surgery

Along with changing your diet before surgery, increasing your physical activity provides significant benefits:

Cardiovascular Exercise

Getting aerobic activity like walking, swimming, or cycling for 30-45 minutes 3-5 days per week improves heart health for safer surgery.

Strength Training

Building muscle strength and endurance through weight lifting or resistance bands 2-3 days a week preserves lean mass.

Flexibility Exercises

Gentle stretching improves flexibility which aids in recovery. Focus on major muscle groups.

Walking

Getting in at least 30 minutes of walking daily provides many health perks and keeps you mobile after surgery.

Talk to your bariatric surgery team about developing an appropriate exercise program you can maintain long-term.

Making Lifestyle Changes Before Surgery

In addition to dietary and exercise modifications during the pre-op period, making these behavioral changes sets you up for lifelong success:

Stress Management

Find healthy ways to manage stress and emotions without emotional or binge eating. Therapy, meditation, yoga, and journaling can help.

Support Network

Surround yourself with positive people who will cheer you on before and after surgery for encouragement and accountability.

Healthy Coping Skills

Develop new hobbies, activities, and interests so you don’t turn to food for comfort. Keep your hands and mind occupied.

Meal Planning and Prep

Plan out weekly meals and prep food ahead of time for portion control and nutrition. Meal prep is key post-op.

Positive Mindset

Work on maintaining a positive mindset and self-image. Find affirmations that resonate with you.

Implementing healthy lifestyle changes before surgery leads to lifelong success.

Preparing the Day Before Surgery

The day before your scheduled surgery, you will need to start a clear liquid diet. Follow these tips:

Only Clear Liquids

Stick to clear, calorie-free liquids like water, broth, gelatin, and diluted juice. No milk, smoothies, or cloudy liquids are allowed.

Avoid Solid Foods

Do not eat any solid foods starting the day before surgery to empty your gastrointestinal tract.

Fast for 8-12 Hours

Stop all consumption of clear liquids 8-12 hours pre-op as directed by your surgical team.

Bowel Prep

You may need to do a bowel prep to completely clean out your system. Follow any laxative instructions.

Relax and Rest

Spend the day relaxing, staying hydrated, and getting plenty of rest before your operation.

Preparing properly the day before surgery gets your body ready for the procedure and helps lead to better results.

Post-Surgery Diet Guide

After your bariatric surgery, you’ll progress through four stages of eating as you heal and adjust:

Stage 1: Clear Liquids

For the first 1-2 days, you are restricted to clear liquids like water, gelatin, and broth as your stomach heals.

Stage 2: Pureed Foods

Move to smooth purees like yogurt, apple sauce, and pureed soups for a few days as you tolerate it.

Stage 3: Soft Foods

Introduce soft, easy to chew foods like scrambled eggs, well-cooked grains, soft meats, and overcooked vegetables.

Stage 4: Solid Foods

After about 4-6 weeks, your stomach can handle soft solids like tender meats, raw veggies, and fresh fruits without issues.

Progressing through the post-op diet stages slowly allows optimal healing and adjustment to your new gastric pouch.

Making the Pre-Op Diet Work

Here are some tips to help you complete the 6 month pre-surgery diet successfully:

Meal Planning

Portion Containers

Invest in portion-control containers to get used to smaller meal sizes pre and post-op.

Protein Focus

Make high protein foods the center of your meals and snacks to preserve and build muscle.

Hydration Tracking

Use an app or hydration tracker bottle to ensure you get in at least 64 oz of fluids.

Meal Prep

Cook large batches of healthy recipes on your days off so meals are ready to grab all week.

Using these strategies helps make the pre-op diet more manageable as you prepare for a lifetime of success after surgery.
