3 Delicious Dinner Ideas for Post Gastric Bypass Surgery

Bariatric surgery makes your stomach smaller, so your post-surgery portion sizes will also be smaller. You must eat a healthy, well-balanced diet after gastric bypass surgery. Getting all the nutritional staples is foundational in sustained weight loss to become the healthiest possible version of yourself. 

Below are three critical nutritional factors contributing to your essential dietary needs after bariatric surgery. 

1. Protein

Our bodies cannot store protein, so it’s critical to include a healthy quantity and quality in our daily diets. The body needs a constant supply of protein to repair and replace tissues that become weak or damaged. Experts recommend a minimum of 60 grams of protein each day. Gastric bypass surgery only allows the stomach to hold a minimal volume, so it’s key to include protein-rich foods with each meal to preserve lean muscle mass. Make it a point to consume them first when eating. Lean proteins that are healthy for post-gastric bypass include fish, poultry, eggs, and low-fat cottage cheese.

2. Sugar and Fats

After gastric bypass, dumping syndrome can occur. It may cause diarrhea, nausea, and vomiting. Avoid fried food and things like juice, Susa, and sweets.

3. Fruits and Vegetables 

Fruits and veggies are packed with healthy things like antioxidants, flavonoids, and fiber. After bariatric surgery, they are an essential part of a diet, but you must watch carb intake. Instead, choose low-carb vegetables such as spinach, green beans, asparagus, and cantaloupe.
