Long-Term Diet Plan After Bariatric Surgery

Having bariatric surgery means you are bound to lose a high amount of weight, and once you have recovered from the surgery, you need to focus on achieving and maintaining a sustainable and healthy weight.

Immediately after the surgery, you are advised to consume liquids and soft foods. However, you need to quickly establish a healthy diet plan to maintain a healthy lifestyle. Eating the right food is crucial since your stomach gets smaller after the surgery. You must ensure that you consume nutrient-dense meals.

What you eat will help you in either getting the most out of the surgery or gaining the weight back. Therefore, establishing and following a diet plan after weight loss surgery is integral.

Tips to Maintain Long-Term Bariatrics Surgery Diet Plan

Here are some useful tips that can help you in benefiting the most from the bariatrics surgery diet plan and ensure that you maintain a healthy lifestyle:

1.   Eat Frequent, Small Meals

Once you have recovered from the surgery and your doctor has cleared you for solid foods, ensure that you consume frequent but small meals throughout the day.  Three small meals loaded with nutrients and two healthy snacks every day are ideal.


2.   Avoid Skipping Breakfast

Never skip breakfast. There is a reason why breakfast is said to be the most important meal of the day. It ensures you stay active and energized throughout the morning. It helps in jump-starting your metabolism and your day.

Make sure you consume breakfast within an hour after waking up. Eat a hearty and healthy breakfast to increase your energy and improve your mood.


3.   Stay Hydrated

Having bariatric surgery reduces your body’s capacity to hold more food, but it doesn’t reduce the need for your body to stay hydrated. However, it also makes it challenging for you to drink a larger amount of water at once.

Usually, 64 ounces of water is recommended every day to people after the surgery. The best way to make sure you stay hydrated is to take smaller and slower sips throughout the day.

4.   Stay Active

Regularly exercising and ensuring that you stay active throughout the day are necessary after the bariatric surgery. Once your doctor clears you for physical activity, you can do any type of physical activity, including walking, running, swimming, cardio, and strength training.

Keep in mind that while exercising should hurt, it is also not supposed to be easy. Find an activity you enjoy. You can even dance for a few minutes, do yoga, or take up a sport. The idea is to keep moving. However, stay away from rehydrating drinks and energy drinks as they contain a high amount of calories, salt, and sugar.

5.   Nutritional Supplements

Even if you continue to follow the right diet plan after the bariatric surgery, it can get challenging to consume enough nutrients from the food. To make sure your body has a sufficient number of vitamins, fiber, and protein it needs, it is recommended that you take nutritional supplements.

Consuming multi-vitamins every day after the surgery is the right step. Additionally, you can also consume protein shakes, particularly during the initial few weeks after the surgery.

6.   Drink Sufficient Fluids

Water is the best fluid you can drink during this diet, but you can also include decaffeinated, non-caloric, and non-carbonated drinks. Make sure you take small sips throughout the day, as it is very easy to get dehydrated once your pouch’s capacity is reduced.

You need fluids to ensure your digestive tract properly functions. Moreover, it also helps during the digestion process as fluids can assist in breaking down the foods.

7.   Avoid Eating and Drinking Simultaneously

Eating and drinking at once are not recommended in this diet. The capacity of your stomach is limited after bariatric surgery, which is why drinking during meals should be avoided. Drinking while eating will quickly fill up your stomach with fluid, and you won’t get sufficient nutrients.

Focus on drinking fluids thirty minutes before and thirty minutes after the meals. Having too much liquid before or right after your meals would also give the floating food sensation, resulting in nausea.

8.   Maintain A Food Journal

One of the best ways to ensure you follow the diet plan is to maintain a food diary. Write down all the foods you have consumed and their quantity. It will help you monitor your sugar, fat, protein, and calorie intake. It will also help identify the problem areas so that you can take action according to your goals.

Be sure to follow these tips to help you maintain the long-term diet plan after the bariatric surgery. This will help you in benefiting the most from the surgery.

Risks of Bariatrics Diet Plan

The major risk of going on a bariatrics surgery diet plan is when the diet is not properly followed. Eating too much or consuming food you shouldn’t result in complications, including:

  • Dehydration– since you are not supposed to consume fluids during your meals, it increases the chances of dehydration. Not consuming sufficient water throughout the day result in dehydration.
  • Dumping syndrome– a high amount of food entering your small intestine rapidly can result in diarrhea, sweating, dizziness, vomiting, and nausea. Eating too fast or too much, not properly chewing, and high consumption of sugar and fat can result in vomiting and nausea.
  • Blocked opening of stomach pouch– not consuming the right food can lead to food getting stuck in the opening of the stomach pouch. In rare cases, it can also happen if you are following the diet. The symptoms include abdominal pain, vomiting, and nausea. Get in touch with your doctor immediately if these symptoms stay for longer than two days.
  • Constipation– lack of fiber intake and no physical activity can result in constipation.

Takeaway: Consistency is Key

Bariatric surgery results in major weight loss and requires you to consume the right food after to maintain the loss and establish a healthy lifestyle. Consuming the right food in the right amount and staying hydrated is crucial in the long-term diet plan after the surgery.

However, the key is being consistent.

No matter how much healthy food you consume, if you aren’t consistent, it will eventually stop benefiting you, and you will end up gaining weight. Of course, you are allowed to slip up now and then, but you must closely follow this diet to keep the weight off and lead a happy, healthy lifestyle.
