8 weeks Post RNY and down 40 lb since surgery. I have a few basic staples that I buy every week: Yogurt, cottage cheese, cucumbers, protein shakes, tuna, eggs, luncheon meats, baby bel or cheese sticks, flavored cream cheese (the chive and onion is perfect for spreading on the luncheon meats and rolling up with a cheese stick) turkey pepperoni.
I am a creature of habit so I usually eat a lot of the same types of things for lunch. A protein shake for breakfast and a high protein yogurt for a snack. Lunch is egg/tuna salad, or luncheon meats and a cheese stick, a bit of rotisserie chicken, some olives, pickles, baby bel, or cottage cheese. I usually go for the protein stuff first and have a hard time finishing the olives or pickles so I get those mini packs and they will last several days. I tried the quest chips but could only eat 3-4 and the rest of the bag got thrown away so I don't buy them anymore. I bought a loaf of keto bread because I was craving a sandwich and ate one piece and then put the rest of the loaf in the freezer so it wouldn't go to waste and I can eat another piece if I have another craving.
For dinners it depends on what I am making hubby. If I am making him say spaghetti, I add meatballs. I added zoodles to mine but I couldn't finish the meatballs so I skip the zoodles for now and just eat the meatballs but will come back to them. If he is bbqing I will make a few tiny hamburger patties (2.5 oz uncooked) and he will cook them for me. I ask him to cook a few of them less done so that I can microwave them for lunch for a couple of days. He bbq carne asada street tacos this weekend and I ate the meat with a bit of cheese and guacamole on it.
I made stuffed mushrooms with crab and cream cheese with parmesean cheese. Again those were delicious but I made too many and they really don't keep and I had to throw quite a bit away (hubby doesn't like mushrooms). Pretty much what he is eating, I can add or incorporate something he is eating with me. If he eats pizza, I get a small frozen cauliflower pizza and will cut it in half or if it is bigger, cut it in quarters. Suggest buying the smallest you can find because the bigger ones are four servings and I can't eat that four days in a row. I have tried salad but it is pretty much wasted space in my small tummy so I try to eat protein first. I went out to a Mexican restaurant and got refried beans once and it was good. Another time I got a taco salad and at the meat (chicken) and cheese off the top with a mix of the guacamole and sour cream mixed in. Only a small amount (about 1/2 cup) is sufficient. My husband tries to accommodate me and orders something that I can eat so we can share a meal.
Also focus on liquids. It seems to help me continue losing. I ordered decaffeinated chai tea bags on Amazon and drink about 20 oz of them a day then I drink the rest water. I try to get between 65-75oz a day.
My biggest problem is making too much. I guess my eyes are bigger than my stomach still but I am getting so much better at it. I sometimes can't believe when I am about to eat that such a small amount will fill me up. Especially when I am hungry, I am like no way is this going to fill me but it does. It's definitely a surreal process but takes some trial and error. Also I have found that I can maybe eat leftovers on certain things and other things I don't tolerate well.
