7-Day Bariatric Meal Plan: What To Eat After Surgery

Bariatric surgery is a weight loss procedure that may help some people lose weight.

The ideal candidate for surgery is someone who lives with obesity and has tried several weight loss attempts without sustainable results.

Attempts may include dieting and lifestyle changes or gaining back weight after using weight loss medications. 

After weight loss surgery, you can expect to make several dietary changes that support healthy weight loss.

These changes include eating smaller portions more frequently, eating and drinking at different times, and taking supplements to avoid deficiencies. 

To help you adjust to your new eating plan, try following our 7-day bariatric meal plan after recovering from your procedure.  

Working with the dietitian before and after surgery is recommended for best outcomes.

Bariatric Basics: Getting Started

There are several different types of bariatric surgery, and your surgeon will recommend the best option for you. 

Factors that may influence this decision include:

• Your current weight. 
• Health status. 
• Age. 

Types of Surgery 

The two most common weight loss surgeries in America are sleeve gastrectomy and Roux-en-Y gastric bypass. 

Both surgeries require stomach stapling to create a smaller pouch, and bypass surgery requires re-routing of the small intestine to decrease calorie absorption further.  

Although these procedures are unique, the objectives are similar: 

1. Limit the stomach size to reduce the capacity for food, which may naturally result in fewer calories consumed. 

2. Alter the stomach and digestive tract to improve hormone signaling. This change, combined with weight loss, may improve hormone-based dysfunction such as insulin resistance (a hormone that aids with blood sugar levels.) 

A third bariatric surgery option is the adjustable gastric band.

However, it’s declining in popularity because it has a higher risk of complications than the other two options.

What to Eat after Bariatric Surgery

There are three diet phases you should follow after bariatric surgery to promote a healthy recovery.

‍Your healthcare team will tell you when to graduate to the next phase.

Phase 1 (Clear Fluids) 

Immediately after surgery, your digestive system needs to heal, and you should avoid eating solid foods that could stimulate your gut. 

To stay hydrated, you’ll receive clear fluids for three to seven days after surgery. You can expect to drink:

• Fruit juice diluted with water. 
• Clear broths (chicken, vegetable, beef). 
• Decaffeinated tea or coffee.  
• Jello. 

Phase 2 (Full Fluids) 

Full fluids are opaque and contain more nutrients than clear fluids.

Examples include milk, creamy soups, yogurt, applesauce, pudding, cottage cheese, and blenderized lentil soup. 

Protein intake naturally increases as you choose more nutrient-dense foods, aiding post-operative healing.  

You can expect to follow the full fluids phase for approximately twenty days or until your body’s digestive system is ready to move to the next step. 

Phase 3 (Soft and Regular Diet)

Approximately one month after surgery, you can introduce soft whole foods back into your diet.

Your healthcare team will recommend appropriate serving sizes. 

In addition to foods from other phases, you can now also enjoy: 

• Canned fish. 
• Eggs. 
• Hummus and dips. 
• Soft potato. 
• Ripe soft fruits, including mango, banana, cherries, etc.  
• Tofu. 
• Cooked vegetables that are easy to chew. 
• Small servings of cooked grains to start because they can be difficult to digest after surgery.  

This list isn’t exhaustive, as there are many other soft foods you can add to your diet.

Phase 4 (Maintenance and Life-long Eating) 

At this phase, you can enjoy all foods in smaller portions.

While building your new eating plan, you should continue your supplement regime to prevent nutritional deficiencies.

After surgery, most people will need an average protein intake of 1.1 - 1.2g/kg to maintain muscle mass.

For example, someone who weighs 90kg (200lbs) will need approximately 108g of protein daily. 

When sitting down to eat, eat protein foods, then vegetables or fruits.

Use fats to add flavor and keep food moist.

Meal Plan for Bariatric Surgery

These meals and snacks are examples of what you could eat after you’ve recovered from bariatric surgery and include foods from phase 3 and phase 4.  

Talk to your dietitian to learn what serving size is appropriate for you.

Most people limit their meals to 8oz (1 cup) for the first year. Overeating can increase the risk of stretching your stomach pouch. 

Listen to your hunger and fullness cues and stop eating at the first sign of fullness, which may feel like pressure in your upper chest.

Tips for Meal Preparation

If your schedule allows, prepare and freeze meals before surgery.

That way, you’ll have some meals covered when you come home, and you can focus on recovering.

Easy-to-make options include blended soups, such as lentil or garden vegetable soup. 

Other quick and easy options to have on hand include meal-replacement beverages.

Ideally, pick low-sugar brands such as Glucerna.

Too much sugar after surgery can make you feel sick and may trigger dumping syndrome, an unpleasant group of symptoms (diarrhea, light-headedness, nausea, feeling tired after a meal) caused by rapid gastric emptying. 

Takeaway

After recovering from bariatric surgery, you can eat many different foods, but you may have to adjust your portion sizes. 

Aim to eat smaller, more frequent meals throughout the day and include snacks rich in protein and fiber.  

If you need help managing your nutrition after surgery, consider working with a registered dietitian. 

Together, you can create a plan to help satisfy your nutritional requirements while working towards weight loss.
