Bariatric Surgery Post-Op Eating
But you'll get your own diet, designed by your bariatric nutritionist, and you should follow it to the letter. Make sure you tell everyone what you can and can't eat.
I didn't have any food allergies and I remember drinking a lot of beef broth, the expensive stuff, and stuff made with Magic Milk, which won't work for you. Bouillon is too salty, but you can buy real broth, or make it yourself. Most stores have it in large containers, not little soup cans. Get a recipe off the internet for how to make broth using oxtails or veggies or chicken. You can also consume juices, and almost any vegetable can be juiced, and/or cooked & strained. You probably wouldn't want to drink real whey, but it's nutritious as heck. It's a challenge to find stuff that's not overly processed or based on carnivore's diets, but it can be done. Just remember you don't have to do it for very long, and do a LOT of research on possibilities.
There is such a thing as water intoxication. I first heard about it when mandatory drug screening was coming on and people thought if they drank enough water, they could flush their systems. Turns out they were wrong. Any more than a gallon a day is probably not that good for you, and I've recently read articles debunking the 8/8 government recommended water consumption.
But I, too, love water and only drink filtered or spring water which I keep in the fridge and ration out into plastic bottles. That way it's measured, as well. I generally drink three 23.7 fl. oz. bottles every day, and that's plenty of water for me. I keep it next to my bed, also, and take a good drink if I wake up during the night, which I do, a lot.
Though some might say it doesn't count, the water you consume in coffee or tea is legit. Add it to your total.
