After bariatric surgery, patients will be encouraged to follow the low-carb diet tips put in place by their bariatric program to help them lose and maintain that weight loss through the years. Hopefully, you have learned the importance of a low-carb diet in your bariatric program. However, if you are searching for resources online about getting started, this is a great place to look. 

Carbohydrates are naturally occurring sugars, starches, and fibers found in food products. Like fats and protein, carbohydrates are a macronutrient, meaning a nutrient that must be consumed in relatively large amounts as fuel for the body. In fact, you may have heard that carbs are the body’s primary source of energy. So if carbs are so highly praised, why would you want to follow a low-carb diet after weight loss surgery? 

Types of Carbohydrates 

First, it is important to understand the role carbs play in the body and the different types of carbs. All carbs fall into one of two categories – simple versus complex. The main difference between these two types of carbs is their chemical structure and how easily they are absorbed. 

Complex Carbs

Complex carbs are those high-fiber foods that contain vitamins and minerals. They are known as the “good guys” and provide sustained energy levels compared to simple carbs. 

Simple Carbs

Simple carbs should be limited (except in cases where you need additional energy before endurance events) as they contain only one or two forms of sugar and no vitamins or minerals. The body easily and quickly processes simple carbs as sudden bursts of energy. Your body does not become full for long after eating these “empty calories.” 

The consumption of simple carbs can also lead to a sudden spike in blood sugar levels, which can be dangerous for people with diabetes who need to maintain their blood glucose. When the blood sugar levels increase, the pancreas produces more insulin, which promotes fat storage. If you are not using the increased glucose levels through exercise, it will turn into fat and can cause weight gain. That is why studies have linked simple carbs (high-glycemic foods) to medical conditions such as diabetes, obesity, heart disease, and cancer.

Low-Carb Diet Tips

The most common low-carb diet tip you will hear after bariatric surgery is to limit your carb consumption to 50 to 75 grams of carbs a day. However, other websites categorize low-carb based on the following parameters: 

Very low-carb: 20–50 grams of carbs per day

Low-carb: 50–100 grams of carbs per day

Moderate-carb: 100–200 grams of carbs per day

Although it can be tempting to follow a very low-carb diet and significantly restrict your carb intake to speed up your weight loss, we recommend taking it slow to ensure you maintain a healthy energy level. Also, you will want to customize your grams of carbs each day based on your activity levels and your body composition.

How to Incorporate our Low-Carb Diet Tips Into Your Lifestyle 

Transitioning your lifestyle to follow a low-carb diet can be challenging if you haven’t prepared and created a nutrition plan. When following low-carb diet tips, the first thing to remember is to avoid simple carbs (cakes, cookies, chips, etc.) and starchy vegetables (potatoes, corn, squash, etc.). You want to fill your fridge with many vegetables, protein, and dairy options. Most registered dietitians praise the consumption of all fruits and vegetables. However, patients looking to lose weight must watch out for the carb count within fruit. We suggest bariatric patients stick to berries and melons as they are the best options.
