When you say liquid, there are 2 types, a clear liquid diet and full liquid. Not sure which you will be on but typically ppl are on clear first then full liquid.

For clear liquid I had:

Chicken/Beef Broth

G2 or Vitamin Water (for the electrolytes)

Jello

Herbal Tea (Chamomile did wonders for my stomach)

Once I progressed to full liquid (the liquid should roll off spoon like milk)

100 calorie greek yogurt that has been thinned with skim milk and strained to remove fruit seeds/bits

Cream soups (potato, cheese, broccoli) that are made with skim milk, and then thinned with skim milk and strained

I made peanut butter bananna smoothies using skim milk, greek yogurt, banana, and PB2 (powdered peanut butter) IT WAS DELISH (just strain first)

Also Trop 50 OJ cut with 50% water has been a great way for me to get a big old scoop of protein powder down in the morning.

I've also had Coco wheats made with skim milk, thinned with skim milk and a little sweetener.

Don't go out and buy a ton b/c you are going to be shocked at how little you can actually consume!!

I'll be moving to puree/soft foods in about a week so I'll let you know what stuff seems to work well for that stage

thank you so much!!! oh wow powder peanut butter? never heard of that!! i'll deff be buying that!! Thank youuu
