The First Few Weeks After Bariatric Surgery

Would love your thoughts, please comment at the end of the post!

Our US-registered bariatric nutritionist discusses the first few weeks’ diet after weight loss surgery. She underlines the importance of measuring spoons and dime size bites post surgery.

Hi, everyone! I wanted to do a post today about eating in those first few weeks after bariatric surgery. I have had some questions from people that are struggling with either some nausea or even some vomiting after bariatric surgery.

Feeling like they are eating slowly but maybe they are still struggling but maybe you know you are eating fast. So anyways, these are my props to help show you.

Now, first few weeks if you are still on all-liquids:

  • You want to get out your measuring spoons.
  • These are mine and you want to keep your sips of liquids to a teaspoon or less.
  • As you can see, this is my half teaspoon, quarter teaspoon.
  • Now, a teaspoon, my thumb fits clearly well in and half a teaspoon, it is kind of just this, so, the size of your thumb at the very, very tip. It is kind of good measurement to keep.
  • If you are having really hot liquids like hot tea, hot coffee or ice cold liquids is well you might want to do a smaller amount, more like the quarter to half teaspoon size.

All Liquid Diet After Weight Loss Surgery

The All-Liquid Diet

  • For whatever reason, those extreme liquids tend to be a little bit harder to tolerate.
  • Room temperature usually works better. So, keeping this out, on the counter, as you are going to sip your protein drink or your water or whatever it is, as a reminder to not gulp.

Solid Diet Post-Op

  • The other thing, if you are moving to more solids is to get out the dime. Here is my dime.
  • You do not want to have bites that are any bigger than the size of a dime.
  • Thickness wise, you can maybe do two dimes for thickness but overall just keep that dime on the counter when you are having your meal as a reminder of how big each bite should be.
  • When you do have those bites, wait at least thirty seconds, in between each bite
  • So essentially, you should have no more than two bites of food per minute.

Sometimes, I think, it is good to just wait a minute, initially, between each bite to really learn where that (2:13) is for yourself.

Portion Size

  • Portions, for most people are somewhere about quarter to half a cup. This is my quarter cup serving, as you can see, next to my tablespoon. It is pretty small.
  • Having that amount out, can really help, just be a good visual from where you want to stay. Hope this helps!

Time Your Bites

I also think about having a timer with me but even using your phone and using the stopwatch setting, so that you can watch how many bites you are taking per minute can really help to slow things down.

You are not going to have a lot of fun to eat with for the first couple of weeks or so but I promise, just taking this time now:

  • To practice eating slowly
  • To pausing between bites
  • To putting your fork or spoon down between bites

All of these little actions can really help set the basis for mindful eating and to hopefully prevent that nausea and vomiting after bariatric surgery, that some of you may be experiencing. Alright, thanks again. Bye.
