Gastric sleeve surgery is an effective method for reducing body weight by decreasing the stomach's size, leading to a smaller appetite. The effectiveness of this surgery heavily relies on both pre- and post-operative diets. This article focuses on the soft food diet phase after gastric sleeve surgery, providing guidelines, food choices, and essential tips for a successful recovery and sustained weight loss.
Understanding the Bariatric Diet Progression
After gastric sleeve surgery, patients progress through several dietary phases to allow the stomach to heal and adjust to new eating patterns. The typical progression includes:
- Clear Liquid Diet: Day 1 (in the hospital)
- Full Liquid Diet: Days 2 to 14 (2 weeks)
- Pureed Diet: Days 15 to 30 (until 1-month visit)
- Soft Diet: Days 31 to 60 (after 1-month visit)
- General Diet: Day 61 to forever
This article concentrates on the soft diet phase, which typically begins about one month after surgery.
The Soft Food Diet Phase (Days 31-60)
The soft diet phase is a crucial step in transitioning from liquids and pureed foods to a more general diet. It allows the body to gradually adjust to solid foods while ensuring adequate nutrition and preventing complications.
Guidelines for the Soft Food Diet
During the soft diet phase, it's essential to follow specific guidelines to promote healing and avoid discomfort:

- Chew Thoroughly: Chew foods to a pureed consistency, approximately 20 to 30 times before swallowing.
- Eat Slowly: Take 30 minutes to finish each meal.
- Portion Control: Eat three milk snacks and three soft food meals per day.
- Hydration: Drink six to eight 8-oz glasses of water daily.
- Supplements: Take prescribed vitamin and mineral supplements.
- Exercise: Incorporate strength-building exercises into your daily routine for about 60 minutes each day.
Lifestyle Changes
Adopting lifelong lifestyle changes is critical for long-term success after bariatric surgery:
- Eat Regularly: Consume three meals a day.
- Balanced Meals: Include a protein and a carbohydrate choice at each meal, prioritizing protein intake.
- Nutrient-Dense Foods: Focus on vegetables, whole grains, fruits, and lean meats.
- Avoid Problematic Foods: Avoid calorie-dense foods like chips, cookies, fried foods, and non-nutrient-dense foods like pretzels and rice cakes.
- No Carbonated Drinks: Avoid carbonated fluids, as they can cause stomach pain and provide unnecessary calories and sugar.
- Avoid Citrus: For the first three months after surgery, avoid acidic or citrus foods like tomatoes, lemons, oranges, or limes.
- No Straws: Avoid using straws to prevent air bubbles from forming in the pouch, which can cause pain.
- No Tobacco or Nicotine: Do not use tobacco or nicotine products. It slows down healing and can lead to complications.
Milk Snack Choices
Include three milk snacks each day, selecting from options such as:
- 1 cup skim Fairlife milk
- 5 to 6 oz Greek Yogurt (100 kcal or less)
- 1 cup skim milk
- 1/2 cup Cottage cheese (fat-free or 1%)
- 1 lite mozzarella string cheese stick
- 1 cup unsweetened soy milk (or high protein plant-based milk)
- 1/2 cup Fat-Free Chocolate Milk (mixed with 1/2 cup skim white milk)
- 1/2 protein shake
Milks can be flavored with Peanut Butter Powder, sugar-free chocolate syrup, or sugar-free hot coco mix.
Meal Portion Sizes
During the soft food diet, appropriate portion sizes are:
- Protein: 1/4 to 1/3 cup or 2 to 3 oz
- Vegetable: 1 to 2 bites
- Carbohydrate (fruit & starches): 1 to 2 bites
Suitable Soft Food Choices

Important Considerations
Eating and Drinking Habits
- Sip Liquids Between Meals: Avoid drinking fluids 30 minutes before meals, with meals, or for 30 minutes after meals.
- Avoid Dehydration: Drink at least 8 cups (1.9 liters) of fluids a day to avoid dehydration.
- Eat and Drink Slowly: Take at least 30 minutes to eat your meals and 30 to 60 minutes to drink 1 cup of liquid to avoid dumping syndrome.
Potential Complications and How to Avoid Them
- Dumping Syndrome: Avoid foods high in sugar and fat to prevent dumping syndrome, which can cause nausea, vomiting, dizziness, sweating, and diarrhea. If it occurs, sit or lie down until symptoms improve.
- Dehydration: Sip liquids between meals to prevent dehydration.
- Constipation: Ensure adequate fluid intake (1.5-2 liters daily) and include pureed cereals, fruits, and vegetables in your diet for fiber.
- Blocked Opening of Your Stomach Pouch: Chew food thoroughly to prevent food from lodging at the opening of your stomach pouch, which can cause nausea, vomiting, and abdominal pain.
- Reactive Hypoglycemia: If you experience symptoms of reactive hypoglycemia (low blood glucose), contact a bariatric dietitian for advice.
- Nutrient Deficiencies: Take daily, life-long vitamin and mineral supplementation to prevent deficiencies.
Vitamin and Mineral Supplementation
After surgery, reduced food intake may increase the risk of vitamin and mineral deficiencies. Essential supplements include:
- Multivitamin
- Vitamin B12
- Calcium (1,200 to 2,000 mg daily in divided doses)
- Vitamin D (taken with calcium supplement)
- Iron (especially for menstruating women)
Space out vitamin and mineral intake throughout the day for better absorption.
Food Intolerance
Some foods may be difficult to tolerate after surgery, including chewy or dry meat, bread, fibrous fruits and vegetables, rice, pasta, nuts, and seeds. If food gets stuck, it may be due to eating too quickly, eating too much, or consuming problematic foods.
Tips for Success
- Introduce New Foods Gradually: Introduce one to two new food choices a day to assess tolerance.
- Prioritize Protein: Focus on protein-rich foods at each meal. Aim for 60-70 grams of protein per day.
- Read Labels Carefully: Pay attention to serving sizes, protein content, and the relative protein value (RPV) of foods.
- Track Your Progress: Keep a food and activity log to monitor your intake and identify any issues.
- Stay Connected: Attend follow-up appointments with your bariatric specialist for ongoing support and monitoring.
