From all the research I've done, the popular belief is that caffeine in moderate doses can cause dehydration. It can also have a laxative effect in some people. That's why most doctors recommend sticking to decaf after surgery.

However, there is also a large amount of info on the internet saying this isn't true and studies have proven caffeine doesn't dehydrate you and has beneficial effects in small doses. 

My advice would be to check with your doctor and see what they say. You could always try a cup of caffeinated coffee and see how it affects you?

I just had my VSG surgery 2 days ago. The 2 weeks prior to my surgery, I was on a very strict liquid diet with the following rules:

-3 protein powder and skim milk shakes per day

-1 low fat Greek yogurt per day

-small 1 cup lettuce only salad per day

-sugar free liquids and jell-o

-1 can of broth (chicken, beef, veggie) per day

Following this meal plan very closely, and even skipping things like the salad, I lost 23 pounds before surgery. My surgeon told my wife after my surgery was done "his liver looked great. Nice and lean"

hope this helps! Good luck!

Protein shakes are probably going to be the only way you will be getting all your protein in after surgery. Your stomach will just be too small to be able to get in enough by food alone. Good time to try different ones and find the ones you like or dislike.

you are going to need to get used to upping your protein now and after surgery.  There are some good protein suppliments and I couldn't keep mine up without them.  I use Syntrax products and you can go on line and order a sample pack.  Otherwise, deli meat is basically pure protein.  You can use it wrapped around a cheese stick for a snack or add it to your lean cuisine to up the protein in that.  Greek yogurt is great protein too for breakfast or a snack.  Use this time and the time right after surgery to start eating well and keeping your protein up.  Protein is needed for all of our muscles (think heart, it is a muscle too) and will help you keep your hair better than anything else you can do.

I'm in my pre-op program for vsg surgery and my dietician has been having me keep a food log, and she wants me to keep track of the amount of protein I have, she says I should be having at least 60G a day but the highest I am able to make it is 49.

I eat kinda whatever for breakfast that's allowed and then I have a lean cuisine for lunch and dinner. It's been great for weight loss but not for protein, the highest protein lean cuisine I have is only 18G. Does anyone have any tips or tricks on simple or semi-easy ways to get all my protein in?
