Pre Bariatric Surgery Diet

Pre-op lap-band diet

I'm wondering if I'm eating the right foods pre-op.

I was told jacket potato were ok and then read somewhere they're not.

And what about fat free yogurts? They have 0.1 % fat in them so they not totally fat free, are they?

Also, does sugar turn into fat?

The foods you eat in the weeks leading up to your gastric lap-band weight loss surgery are very important!

Of utmost importance is that you don't overeat in the weeks prior to surgery. So it's ok to include potatoes as part of your high protein, low calorie pre-surgery diet...

...just not too many of them!

Many people have difficulty controlling portion sizes of potatoes because they're SO yummy! If this is the case for you, avoiding them may be in your best interest. Otherwise, enjoy a small (1/2 cup or 3 ounce) portion with your meal.

If you want to take all the guess work out of the pre-surgery diet, you can simply utilize a pre-op diet kit.

Read everything you need to know about the pre-surgery diet here, including pre-surgery vitamin supplementation.


Technically, any food can contain up to 0.5 grams of fat (per serving of food) and be considered "fat free."

That's because less than 0.5 grams of fat is considered a nutritionally insignificant amount of fat.


Sugar or any other excess source of calories will be converted to body fat. The important word here is excess.

Sugar can be included in small amounts in the diet and not cause weight gain nor hinder weight loss. However, most people eat too much sugar, and that's why it gets converted and stored as body fat.

Good luck with your pre-surgery diet and approval process too. Keep us updated as to how you're doing.
