Yep, I'm not a medical professional. Five months out and 30 pounds is great. Glad you are refocusing. it's not about losing quickly. Its being consistent and the scale will move.
If you are still in thailand can you contact you surgeon's office? Do they have a dietician? Any paperwork on your instructions? You can always contact another bariatric program to get true medical advice on how to work your sleeve.
Some foods you already know will put you in weight gain.Keep them out of the house so you are not tempted. Also stalls happen. You can search this site to find ideas on how to handle stalls.
Are you weighing and logging your food in a food App like myfitnesspal? This will total your calories protein carbs and fats. It's a great tool. You need to know how you are fueling your body.

Food and calories. You are going to receive hundreds of different diet suggestions from forum members. Again no one is a medical professional on Bariatricpal.
Sounds like your instructions were about the same as mine.( High protein low carb from veggies, exercise, no sugar and water) As you progress out with sleeve surgery you can hold more food. A few things that may help with hunger. Make sure you are hitting your protein goal. 60 to 100 grams. You can raise this number. Add more veggies to fill the extra space. Eat frequent small meals a day. Make sure your food increase is healthy foods that fit your macro goals for the day.
Activity level will affect the number of calories you intake. Some times raising calories can jump start your weight loss again. If you notice a gain you can adjust your calories up or down to find where your body starts back into weight loss mode.
Carbs are energy. I got my carbs in with vegetables for weight loss mode.
This is not a part of my plan - Many people here have different instructions and approaches to carbs. Whole wheat sweet potato brown rice..nothing processed or white.
To each their own on instructions and plans. Find what works for you.
