It is vital in a long run for you to make healthy food choices after your weight loss surgery. It will help you achieve the maximum weight loss goals at the same time maintaining your nutritional needs.
A 4 stage diet plan is recommended to patients after the gastric bypass and sleeve gastrectomy operation. We will provide you more specific guidelines in email. For our English speaking customer convenience we offer a free UK based bariatric dietitian’s consultation after you are back home from your surgery.
Stage 1 – Liquids
The first stage will long up to 14 days after surgery. The first 4-5 days you will drink clear liquids – water / diluted, non sugar juice by small sips all day long / herbal tea, room t. After the first 4-5 days you can add to your diet nutritious liquids like non fat broth, semi skim milk, sugar free jelly, skim yogurt without bits, clear cream soup, tea, coffee, protein shakes.
Remember the necessary amount of liquid for your body is 1.5 – 2 l a day or 30-35ml of liquid on each kg of your body weight. And at least a half of it should be non-caffeine, non-sugar drinks (=water).
Aim to establish your eating schedule and have 3 main meals per day – breakfast (protein rich drink), lunch (1 small cup of soup & 1 small cup of thin yogurt), and dinner (a protein rich drink and or fruit squash), and 2-3 ‘snack’ meals (for ex. a cup of milk,) between 3 main meals. Drink water between all meals.
Avoid sparkling drinks, alcohol, any liquid with bits, fluids with excess sugar and fats – those can make you feel sick or cause rejecting.
Supplements and medications – Dr Olegs Kozlovskis recommends starting vitamin and mineral supplements 2 weeks post bariatric surgery. For the first period PO all vitamins and minerals can be used in chewable or liquid form, if you find hard to have them in tablets. If you are on other medicines, you can crush them and space out the pills at least 5-10 minutes apart.
Stage 2 – Pureed food
After 2 weeks or earlier after the surgery you can move to the next stage of your diet which you should expect to follow up to 2 weeks, depending on your feelings. Listen to your body! All foods at this stage should be of a consistency of thinned mashed potatoes.
Foods to have on this stage – skim milk, blended soups (with skim milk instead of water), blended fruit shakes with or without milk or fat-free yogurt, blended meat in blended cream soups or mashed potatoes, cooked cereal thinned with skim milk, blended beans, mashed potatoes or other vegetables made with skim milk, sugar-free yogurt, blended cottage cheese (fat-free/low fat), pureed fruits.
Foods to avoid – all solid foods, raw vegetables, tough skin on vegetables and fruits (tomatoes, potatoes, also sausages), sweet corn, tomato seeds, red meets, non pureed meet, hard cheese, toast, bread, rusks, nuts.
Beware of high intake of legumes such as chickpeas, lentils, split peas – they absorb lots of fluid in the bowel and can cause discomfort at this stage of diet.
Stage 3 – Semi-solid diet
You should expect to be on this stage of diet for up to 2 weeks (usually 5-6 weeks after the operation). But again – listen to your body and your stomach! Some people can have this stage earlier, some later.
Foods to have: Boiled eggs any type except fried, several types of casseroles, soups, chopped lean meat (except the red one), low-fat cottage cheese, boiled & peeled vegetables, sugar-free low-fat yogurt, fish in a sauce, well-cooked rice, pasta in sauce, mashed beans, chick peas, kidney beans, soft fruit.
Avoid: Any food with tough skin, stringy or fibrous vegetables such as celery, asparagus, sweet corn; fizzy drinks; alcohol – it can irritate the stomach and is high in calories.
Stage 4 – Solid foods
People come to the 4th stage after 2-3 months after the surgery.
Avoid: sugars, deep fried, high calorie, fast foods, carbonated drinks, alcohol.
The consequences of having a poor diet vary. In the short term it may lead to dry or cracked skin or nails or hair loss. In the long term a lack of nutrients can increase the risk of developing several health conditions. It is important to have a balanced diet including all types of foods!
Concentrated sugars and alcohol, greasy foods and overeating can cause a dumping syndrome. It may cause also vomiting and/or diarrhoea, so try to avoid: candies, chocolate, sweetened & carbonated sodas, honey, cakes, ice cream, any alcohol.
It may happen that you do not tolerate some of foods soon after bariatric surgery. Do not worry and try to add these products to your diet later again.
You will need to learn nutritional values of products to be sure you treat your body with love and responsibility and provide all necessary nutrients to it.
There are five main food groups (many products like milk, beans etc. fit into more than one group), you should have in a balanced diet plan. Here you can find products and approximate amounts of each you should include in your daily diet plan. Great variety of products is the key.
You will be provided a more detailed dietary plan and product descriptions before discharging from the hospital.
