What this article covers:
Bariatric Surgery Diet: Preoperative Guidelines
We’ve formulated our preoperative guidelines to help reduce surgical risks and jumpstart your weight loss. Let’s break down the key components of your pre-bariatric surgery diet.
Pre-Op Weight Loss
Losing weight before bariatric surgery might seem counterintuitive, but it’s essential for your safety. Shedding some pounds helps shrink your liver, making the surgical procedure easier and reducing potential complications.
A 2-week pre-bariatric surgery diet is typically recommended 2-6 weeks before your surgery date. This length of time forces your body to use stored carbohydrates in the liver for energy, which helps to shrink the liver.
This 2-week diet tends to be very low in calories, carbohydrates (starches and sugars), and fat. The specifics of this diet are provided by your bariatric practice. Some recommend 3-4 small meals daily, focusing on lean proteins, vegetables, and healthy fats. Avoid sugary foods and beverages to kick-start your metabolism.
For some patients, your diet could consist of 800-1,000 calories, while others may follow a 1,200-calorie pre-bariatric surgery diet, but always consult with your healthcare team for personalized advice.
Liver Reduction: Full Liquid Diet
Some bariatric practices only allow the full liquid diet 1-2 weeks before your surgery. This would consist of high-protein meal replacement shakes that mimic a small meal 3-4 times a day. This can further reduce liver size and prepare your digestive system for the upcoming changes.
This stage is critical for those following a 2-week pre-op gastric sleeve diet.Your full liquid diet can consist of protein shakes, clear broths, sugar-free gelatin, and other approved liquids.
Confirm with your bariatric team which diet is recommended for your specific situation. Some will even allow 2 high-protein meal replacement shakes daily, with the 3rd meal consisting of a small whole-food meal.
Protein becomes a large priority during this 2-week pre-op diet as well as after surgery. TheAmerican Society for Metabolic and Bariatric Surgery (ASMBS) recommends consuming 60-80 grams of protein daily or 1.0-1.5g/kg ideal body weight , depending on your individual needs.1
Our bariatric protein shakes are specifically formulated to help you meet these requirements. These high-quality protein supplements are lactose-free and provide fiber, vitamins, and minerals along with whey protein isolate. With 21 servings per container, they’re an excellent choice for this period and beyond.
What About Medication?
Some medications may need to be adjusted or temporarily stopped in the weeks leading up to your procedure. It’s essential to discuss all your medications with your healthcare team.
Blood thinners, diabetes medications, and certain supplements often require special attention. Your surgeon will provide specific instructions for each medication.
We recommend keeping a detailed list of all your medications, including over-the-counter drugs and supplements, to review with your healthcare provider.
Post-Operation Diet
After bariatric surgery, your digestive system needs time to heal and adjust. The post-operative diet progresses through several stages, allowing your body to adapt gradually.
Full Liquid Diet
The full liquid diet resumes shortly after surgery, typically within 24-48 hours, depending on the procedure. This phase usually lasts 1-2 weeks, focusing on fluids and foods that are normally liquid and foods that turn to liquid when they are at room temperature.
High-protein meal replacements are a good focus. The goal is to keep you hydrated while providing essential nutrients. Sip small amounts frequently throughout the day, aiming for 4-6 ounces per hour.
Our bariatric meal replacement powders are an excellent option during this stage, providing balanced nutrition in an easily digestible form.
They are lactose-free and available in multiple flavors, including chocolate, vanilla, strawberry, unflavored, cappuccino, chicken soup, chocolate peanut butter, strawberry banana, and caramel. Each container provides 21 servings, ensuring you have enough to support your recovery.
Blended Or Pureed Diet
The pureed diet phase typically begins 2-4 weeks after surgery. Foods should be blended to a smooth, applesauce-like texture.
Focus on protein-rich foods like pureed meats, fish, eggs, and legumes. Introduce one new food at a time to identify any intolerances.
Continue to prioritize hydration, drinking fluids between meals rather than with them.
Our bariatric collagen can be easily incorporated into pureed foods, supporting skin, hair, and joint health during your recovery. These high-quality peptides come in an easy-to-mix powder form, are free from artificial additives and gluten, and promote recovery and muscle maintenance post-surgery.
Soft Diet
The soft diet phase begins around 4-6 weeks post-surgery and lasts 2-4 weeks as you transition towards a regular diet.
The texture should be tender enough to mash with a fork. Include soft proteins like flaked fish, tender chicken, and scrambled eggs. Gradually introduce well-cooked vegetables and soft fruits. Continue to eat slowly, chew thoroughly, and stop eating when you feel full.
Our bariatric protein bars can be a convenient option during this phase, providing a satisfying texture and balanced nutrition. These bars are made with medical quality protein, including whey protein isolate, and are optimized with protein, fiber, and essential nutrients.
They’re an excellent meal replacement for busy lifestyles and support both post-surgery recovery and long-term weight management.
Regular Diet
This final stage reintroduces a wider variety of foods while maintaining a focus on nutrient-dense options. Based on our observations, your new stomach size will require permanent changes in eating habits.
Prioritize lean proteins, vegetables, and fruits. Introduce new foods gradually to assess tolerance. Continue to avoid high-sugar, high-fat foods and beverages.
Our findings show that the Centers for Disease Control and Prevention recommends maintaining a balanced diet with appropriate portion sizes for long-term success.
If you experience difficulties maintaining your weight loss, your doctor might recommend a 5 day pouch reset diet for gastric sleeve to help get back on track.
Other Key Takeaways For Success
Long-term success after bariatric surgery depends on more than just diet. Regular exercise, proper supplementation, and ongoing support all play important roles.
We recommend starting a gentle exercise routine as soon as your doctor approves, typically within 4-6 weeks post-surgery.
Vitamin and mineral supplementation is essential after bariatric surgery. Your body’s ability to absorb certain nutrients changes, making supplements a necessity for preventing deficiencies.
Our Bariatric multivitamin is formulated to meet your post-surgery nutritional needs. They contain essential vitamins and minerals and are available in both chewable and capsule forms.
Additionally, our Bariatric calcium chews, like the Lemon Calcium Citrate Soft Chew, help sustain calcium intake. Each chew provides 500 mg of calcium citrate and 500 IU of vitamin D3, supporting bone health in a tasty, easy-to-digest form.
