Both before and after your weight loss procedure, you will need to maintain a healthy diet. At University of Missouri Health Care, our registered dietitians use the latest nutrition research to develop a personalized eating plan just for you.
Your registered dietitian is an important member of your weight loss team. At MU Health Care Bariatrics, our registered dietitians help you maintain weight loss and prevent malnutrition following surgery with comprehensive nutrition education and the tools you need to maintain your new lifestyle.
Eating after weight loss surgery
Our registered dietitians help you transition to your new lifestyle before you undergo surgery through preoperative education classes. In addition to supporting your weight loss through education, we help you develop new habits you’ll need for a healthy post-surgical life.
These habits include:
- Drink fluids between meals, but not with meals. After surgery, stop drinking 30 minutes before a meal and wait at least 30 minutes after a meal to start drinking again. Drinking fluid while eating or immediately after eating will cause the food to leave your pouch, making it easier to eat more food at one time or creating the desire to snack later.
- Drink at least 64 ounces of low-calorie, sugar-free fluid every day to stay hydrated.
- Take small bites and chew your food at least 10 to 20 times (or more) before swallowing. Food should be the consistency of toothpaste or applesauce before you swallow.
- Give up or reduce caffeine intake.
- Do not drink alcoholic beverages for at least one year after surgery. After that, alcohol must be consumed in moderation, as it can cause stomach ulcers and increase your calorie intake.
- Avoid carbonated beverages (including regular soda, diet soda, club soda and beer). Carbonated beverages place air into the pouch which can cause gas, bloating and discomfort.
- Avoid using a straw until you have trained yourself to sip fluids instead of gulp. Straws cause us to drink faster than normal and can also cause air to enter the pouch.
- Eat three meals every day.
- Do not snack or graze between meals.
- Do not skip meals.
- Take recommended bariatric-specific vitamin and mineral supplements.
These habits help you keep your new stomach pouch small, maintain weight loss and avoid malnutrition.
Meals after weight loss surgery
To ensure you get the nutrition you need without becoming overly full, you should eat your meals in this order.
- Eat lean protein first. Women need at least 65 grams of protein per day and men need at least 80 grams of protein per day. The best sources of protein are:
- Cottage cheese
- Protein supplements
- Wild game
- Eat non-starchy vegetables second (such as leafy greens, green beans, broccoli, carrots, etc.)
- Eat fruit third.
- Eat whole grains OR starchy vegetables (potatoes, corn, peas) last.
