Always default to your bariatric surgeon and nutritionist's post surgical eating plans, however, when in need of a reminder, there are various plans online that you can fall back on like this sample one adapted from Duke Health -
Stage 4: Solid Foods
It is now 10-12 weeks post surgery and you are ready to progress from soft solids to regular consistency foods. Eventually, you will probably be able to eat most of what you were eating before surgery, only in much smaller amounts.
Overall you should be making healthy food choices including lean meat or vegetable protein, low-fat dairy, incorporating fruit and vegetables as you are able, and avoiding empty calorie or “junk” foods as they are typically high in fat and sugar.
Long term, patients must choose foods with good nutritional value. Each meal should have at least three ounces of protein. Learn to read food labels and limit fat and sugar intake, choose low-fat (five grams or less per serving), low-sugar (five grams or less per serving), and lean protein foods.
The volume you can tolerate will always be limited so choose foods wisely to avoid filling up on foods with little nutritional value.
- Eat slowly and be aware of when you feel full. When you feel full, stop eating! If you continue to eat, you may develop intense chest pain and vomit.
- Chew, chew, chew! You need to make sure you chew your food very well before you swallow it. This makes it easier to digest and pass from your gastric pouch into your small intestine.
- Avoid drinking fluids 30 minutes before and with your meals. If you fill up your small gastric pouch with liquid, you won't have room for your food. Furthermore, the liquids may accelerate passage of the solid food out of the stomach and possibly cause some discomfort.
- Drink enough fluid between meals to meet your fluid requirements. You need six to eight cups of fluid per day to prevent dehydration.
- Avoid food and beverages high in sugar. High sugar foods can cause "dumping syndrome." After gastric bypass surgery, some people feel light-headed, sweaty, or faint soon after consuming concentrated sugar.
- Limit high fat foods. These foods may make you feel nauseated. They are also high in calories and will slow down your weight loss. Using a low-fat, reduced-fat, or light version of a product is okay.
