Specialized bariatric follow-up care is needed lifelong in order to assess nutritional status, weight loss surgery-specific lab work, nutrition intake, and exercise. It’s also important to assess supplement intake and prevent vitamin and mineral deficiencies.

It has been proven that adherence to a regular nutritional follow-up contributes to long-term weight loss success and prevents weight regain after bariatric surgery because healthy eating habits are encouraged and unhealthy habits can be managed without delay. 

Nutrition pillars to live by after weight loss surgery:

  • Focus on high protein, high fiber food choices at meals and snacks
  • Eliminating beverages containing carbonation and sugar   
  • Eating 3 meals/day, possibly 2 snacks   
  • Mindful of starch portion sizes  
  • Making healthy choices when eating out                        
  • Chewing well and slowing down when eating
  • Drinking at least 64 oz of sugar-free, caffeine-free fluids daily
  • Separating liquids from solids and wait 30 minutes to resume drinking
  • Adhering to vitamin/mineral supplements for life
  • Set realistic and achievable goals

Calorie Tracking

There is strong evidence that self-monitoring your progress through calorie tracking and regular weigh-ins/taking measurements improves weight loss nutrition outcomes and helps you stay on track with your lifestyle changes. Food tracking can be done through journaling, using an app, or taking pictures of your meals. Explore what option is best for you.

If you like apps, Connect with us on Baritastic. Baritastic is an app for those who have had weight loss surgery. Beyond just calorie tracking, the app offers supplement reminders, water/food timers and reminders, weight loss tracking, measurement tracking, access to Atlanta Bariatrics's handouts, recipes, and more.

Other great apps for calorie count: MyFitnessPal, Lose It!, FatSecret, Lifesum, MyNetDiary, Calory.

Vitamin Needs

VSG and RNY are malabsorptive procedures, requiring adequate vitamin supplementation to prevent deficiencies due to the reduction in food intake after surgery.

Always work closely with your Registered Dietitian for a personalized supplement regimen based on your individual bloodwork. Here are some basic pointers:

  • Our office recommends Bariatric Advantage, Celebrate, or Bariatric Fusion supplements because they use premium ingredients, providing a higher degree of safety and efficacy.
  • Unfortunately, many companies use lower-quality ingredients to reduce costs. This is not typically reflected on the label.
  • Remember: the FDA does not regulate vitamins, so using a reputable company is important. If you are thinking of trying a new product, always check with your Registered Dietitian first, even if the supplement claims to be a bariatric product.
  • Taste, although important, should not be the main factor in choosing a vitamin. Many “gummy” vitamins offer little to no nutritional value.

When choosing a multivitamin after weight loss surgery, it's important to ensure the product meets the ASMBS supplement guidelines in order to prevent vitamin and mineral deficiencies throughout the lifetime. Over-the-counter supplements do not provide adequate amounts of vitamins and minerals after surgery which can lead to bone loss, muscle loss, neurological issues, and anemia after weight loss surgery.

The recommendations for bariatric supplements are as follows:

MultivitaminsDaily Intake
ThiaminAt least 12 mg/day
Folic Acid400-800 mcg/day
(800-1000 mcg/day for female child bearing age)
Copper2 mg/day (RNY) | 1mg/day (Sleeve)
Zinc8-22 mg/day (RNY) | 8-11 mg/day (Sleeve)
B12350-500 mcg/day
Vitamin D3000 IU/day
Vitamin A5000 -10,000 IU/day
Vitamin E15 mg/day
Vitamin K90-120 mcg/day
Iron45-60 mg/day
CANNOT take with Calcium *may be individualized w/ RD
Calcium1200-1500mg/day (take in divided doses of 500-600mg)
Calcium Citrate – take with or without food
Calcium Carbonate – take with food
*may be individualized w/ RD if eating high amounts of calcium foods

In our office, we have several products that are safe to consume and meet the requirements. Below are some of the options available:

  • Bariatric Advantage Ultra Solo with iron: Serving: 1 capsule per day.
  • Bariatric Advantage Chewable Advanced Multi EA: Serving: 2 tablets per day.
  • Bariatric Advantage Ultra Multi with iron: Serving: 3 capsules per day.
  • Bariatric Advantage Multi Chewy Bite: Serving: 2 chews per day. Does NOT contain iron, copper, or enough thiamin. Would need to also take the Bariatric Advantage iron capsule with thiamin and copper with the multivitamin in order to meet needs
  • Celebrate One Multivitamin w/ 18 mg of iron: Serving 1 capsule per day.
  • Bariatric Fusion MVI Capsule with iron: Serving: 1 capsule per day.

Protein Supplements

How to choose a protein supplement?

The number of protein powders out there is a little overwhelming. Your dietitians have created a list of good quality protein powders/ready-to-drink shakes for you. You may be wondering how it decided on which protein supplements make the cut. Here are some of the items that are considered:

  • Macronutrient Content - < 150 calories, < 7 g sugar, ~ 20 g protein
  • PDCAAS Score - Protein Digestibility Corrected Amino Acid Score
  • Adulteration - Manufacturers may add taurine to trick the protein content tests, which is known as protein spiking
  • False Advertisements - For example, a company claimed their protein powder could be triply absorbed and 1 tablespoon would provide 30gm protein. Unfortunately, that is not possible and the people using the supplement were only getting 10gm of protein, not the 30gm they were promised.  The studies done with this product were on < 20 participants, which is not a large enough sample size to be considered significant research

If you have questions about protein supplements, please contact your dietitians or download the Approved protein list on the Baritastic app OR have a link to download the document.

Pre-Op Diet information

In preparation for surgery for those with a BMI >50, there is a 2-week pre-op diet to follow. The diet is low in fat and sugar in order to shrink the liver, which will give your surgeon a better visual of the GI tract. Solid foods are still allowed during this time. It is not a liquid only  Please refer to the appointment guide that your scheduler will send you for when to start the diet.

One meal each day will be a protein shake, and it's fine to use anything on the approved protein shake handout, not just Bariatric Fusion shakes. Please let your dietitian know if you have any questions about the plan.

If you are below a BMI of 50, please do not follow the pre-op plan unless instructed to do so by your medical team.

Post-op diet progression for sleeve and bypass

The standard post-op diet progression is below. The phases will be discussed in detail during pre-op class and you will receive a packet with the diet information. The packets are posted to Baritastic as well.

  • Sleeve: 
    • Week 1: Liquid Diet
    • Week 2-4: Soft Foods
    • Week 5 and Beyond: Solid Foods
  • Bypass:
    • Week 1: Liquid Diet
    • Week 2: Pureed Foods

Support groups

One of the most important things to remember about your bariatric surgery journey is that you're not in it alone. Emory Johns Creek Hospital and Northside host support groups for patients and providers to connect and support one another in meeting and maintaining their goals.

Exercise Guidelines

Week 1-6:

Walking or recumbent bike only. Other exercises will engage your core. Limit exercise to 10-15 minutes per day. No swimming/hot tub use. In the first 2 weeks post-op, make sure to get up every hour you're awake to walk a lap around the house, which helps with gas pain and blood clots.

Week 6 and beyond:

Most restrictions are lifted after week 6. Follow the guidelines that your surgeon provided. Aim for 150 minutes of cardio and 2-3 times per week of strength training. 

Cardio examples: walking, jogging, biking, skating, swimming, dancing, kickboxing

Strength training exercises: weight lifting, resistance bands, yoga, push-ups, rowing 

Until you are tolerating 3 oz of protein, 1/2 cup of vegetables/fruit, and 1/4 cup of starch, exercise should not exceed 150 minutes of aerobic activity and 2 days of strength training. Weight stalls can be caused when a person is performing vigorous exercise without being able to consume enough calories to support that workout.
