Really innocent question
Protein is the building block of muscle... virtually every organ of your body is a muscle, the amino acids in protein are essential for every cell in your body to function... without protein (meaning literally none, as with actual starvation, certain eating disorders, severe and extreme cases) your body would resort to digesting it's own muscle tissue. Your heart is the muscle that would likely be damaged first, which would be fatal (think heart attack, arrythmia, etc).
Hair loss, poor nutrition, and low muscle tone don't really even compare to what starvation (meaning, lack of amino acids/protein) would do.
With tiny tummies, realistically we could be malnourished, which is worse than it sounds. (Muscle digestion=slower metabolism= less weight loss, hair falling out, very hard to bring up low nutrient levels, more loose skin (from less muscle)... etc).
Glad you got it in the way I intended.
You're right, though, about protein helping you stay full longer. Once you're on solid food/meats, you'll see that dense protein (chicken, beef, etc) fills you up faster, and keeps you full longer than softer proteins (think cheese, beans, cottage cheese, even fish).
Protein in general will fill you much faster (with much less food) and keep you full longer than say a carb (not recommended by many surgeons during losing phase... or like mine, for life) or a soft food like pudding, fruit, veg, etc.
While fruits/vegs are healthy foods, a sleever's diet should follow in this order...
Protein FIRST, veggies SECOND, fruit (third, if room), carbs last (if at all).
At 10weeks out, I occasionally have a bite or two of veggies, haven't tried fruits, and don't eat any carbs (other than what's in my milk, etc). You can see the importance of the vitamins here, when our diets are relatively limited during the losing phase/while our tummies are still small.
Over time, we can eat more, and many veteran sleevers (years out) have a very 'normal diet' with plenty of veggies, fruits, and carbs. (Well, carbs are a gray area--- some do, some don't).
You've come to the right place, use that search bar and learn as much as you can!
As for mushies, I ate greek yogurt (nothing fruit flavored, look for plain chobani or fage, something high in protein, low in carbs/sugars) and added a small amount of SF/FF pudding mix for flavor. I also made my own SF pudding by mixing protein powder in with the pudding mix, and adding the milk to that. Mashed potatoes (if you eat them) or soups (watch the sodium) can be boosted by adding dry milk powder for extra protein. I tried to remember that early on, every bite counts, and I wanted as much protein as I could get in those few bites.
I personally chose to get my protein from cheeses, fish, yogurt, protein drinks/pudding, cottage cheese, ricotta, scrambled eggs, tuna salad, etc and stayed away from carbs. That was my path.
If you haven't checked out the blog, eggface (a post-op RNY) has some great recipes for everything to protein ice cream, purees (mushies)-- LOVE the baked ricotta, it's like lasgna--, and food for later on (pizza, etc). http://theworldaccordingtoeggface.blogspot.com/
Hope that helps!
I'll message you through there, rather than clog up the forums, LOL.
Our bodies need simple sugar for energy. Our bodies are also lazy. If there is simple sugar (carbs from fruit) free floating in our blood streams, out bodies will use that FIRST for energy INSTEAD of breaking down our stored fat into simple sugar and using that for energy.
What that means to you is less fat burned and less weight loss. The more carbs (fruit,veggies,potatoes,rice,pasta,ww bread
