Is yogurt OK for Days 1 & 2?
Yogurt is perfectly fine for Days 1 & 2 "liquids" -- and you can use it as a between-meals snack on the other days. You can always add a protein powder if you feel you need a little protein boost. Remember to measure your portion and eat no more than 1 cup.
Can I have protein shakes on Days 3, 4 and 5?
You can include protein drinks on Days 3-5, but only as between meal snacks if you are hungry. It is best to stick with the menu foods, but on the other hand if you are hungry or "snacky" go for the protein shake. It will rev your metabolism and satiate your hunger. You should be able to get plenty of protein (40-70 grams) from the foods listed, but if not add a protein supplement such as the shakes or if necessary a protein bar. Remember one ounce of protein contains 7 grams of protein (as a general rule) so you need 10 ounces for the full 70 grams - that's just over 3 ounces per meal.
What about milk products for shakes and soups? Are they ok to use on the 5DPT?
If you can tolerate milk, absolutely use it. Many WLS patients become lactose intolerant (me too- bummer!) so that is why there is always a caution about using milk products. But actually, fortified milk is a very healthy part of your diet if you can handle it - and you are right - cream soups with water = ICKY!!!
What is wrong with carbonated beverages?
There are a few reasons carbonated beverages are discouraged. First, they have no nutritional value and beverages that contain caffeine can cause water retention. There is also the theory that for the body to absorb the bubbles oxygen is released from the blood stream to hook up with the oxide molecules and be eliminated through the kidneys and urine. When oxygen levels in the blood go down so does our energy level and our metabolism slows. And the final theory, though just is theory, is the bubbles expand in the pouch.
My reason for not drinking carbonated beverages is that when I was obese I always had a diet coke in one hand a snack in the other. Cannot seem to separate the two so I just don't go there. I don't want to go back.
Aren't soups and shakes slider foods that do not comply with the liquid restrictions? How do they work?
The reason we do liquids the first two days of the pouch test is to give your tummy a break from solid foods, just like right after surgery. Chances are if a person is doing the 5DPT it is because they have been eating things that are not so good for the pouch, so giving it two "healing" days helps reduce inflammation or irritation. I can understand thinking it defeats the 30/30 drinking rule, but it is a necessary step. Learn more about slider foods.
