Post-Op Bariatric Surgery Diet: Phase 2- Thick Liquids
Hi and Welcome to Mexico Bariatric Center. I’m Prudence Ticknor, bariatric dietitian, and Health Coach.
We are discussing phase 2 of the post-surgery meal plan; thick liquids. If you are moving on to Phase 2 of the meal plan, this means you are quickly taking in 64 ounces of fluids, and you feel hungry or ready for the next phase. This usually is anywhere between 2 to 7 days post surgery. The goal here is to continue to get 64 oz. of fluids but now you start focusing on getting the appropriate amount of protein as well. The general range of protein is between 60 to 90 grams per day. If you want to know a more accurate value for you; you would take your ideal body weight and divide that by 2.2. This the minimum amount of protein to maintain your current muscle mass. Making sure you get the proper amount of protein is necessary. If you don’t then some of your weight loss could be from muscle instead of fat loss. The more muscle you lose, the harder it will be to reach your goal weight and keep it off. It also increases the amount of saggy skin you may have post surgery. So for example if your goal weight is 150 pounds then you would divide that by 2.2 and your recommended protein intake would be 68 grams per day.
Although you are getting your nutrients through liquids, you do not weigh your liquids. Your goal is still to consume 64 ounces of fluids per day. You do not start weighing your food until phase 3- soft solids. So what is considered a thick liquid? Anything that is the consistency that can go through a straw, but you do not want to use a straw. You have to remember your stomach went from the size of a flattened football and was decreased to about the size of my thumb, and it will expand to about the size of a small egg. Because your pouch is so small; when you take in the air it can cause a lot of discomforts. Drinking from a straw causing you to take in a lot of air.
During this phase, you can incorporate protein powders to make protein smoothies or pre-made protein drinks. Pureed soups, but be mindful of creamed soups; many people do not do well with milk after surgery and creamed soups are very high in fat. I would recommend you stick with bean or chicken based soups you can blend. I’d recommend using almond or coconut milk instead of regular milk. You can have things like cream of wheat or oatmeal made soup with almond milk. Many people become lactose intolerant due to the sugar in the lactose after surgery and can diarrhea and discomfort. I would recommend using either almond or coconut milk instead of regular dairy milk. For a full list of foods for phase 2 and a sample meal plan click the link below.
Once you start on thick liquids, you will also start taking your vitamins during this stage. Be sure to take your vitamins with food. You will stay in phase 2 until day 14 post surgery and then move onto step 3; soft solids.
