I was on clear liquids for a week and wasn’t hungry. After clear liquids we went straight to soft foods so no liquid phase for me. I’m still not hungry. Savory foods taste better after gastric surgery so focus on broths. Maybe make a red bean soup and blend the peas. Sweet foods are yucky to me too.
You were filled with fluid the day of surgery so you will be bloated for a couple days. Plus your body is still adjusting. It is not advised you weigh yourself before 4-6 weeks
