catechole

You have to eat in between meals to get enough Protein without supplementing heavily with Protein Shakes. It's common to eat every 2 to 4 hours. You cannot, I repeat CANNOT live with the DS on 3 meals a day without multiple protein shakes every day. You malabsorb fat, so just eat fatty meat like bacon. Eat it as much as you want. Just don't eat carbs.

Then you must be years out and have a really big sleeve. Most can only eat 4-6oz food even months out and it is NOT enough to get enough Protein in 3 meals.
Truth is, you don't need to deny yourself when you're hungry. You can just eat fat/proteins. In fact, people often find their weight loss with the DS STALLING because they don't eat enough calories.
