Hi there wondering if anyone could please give me some info!! Here's my situation!! Since having my band my body reacts different too sugar. If I eat sugar it's like my body goes in shock and won't loose any weight. But if I avoid everything with sugar on a daily bases like for two weeks I can sometimes loose up too 4/5 kgs in like 14 days. Meaning I loose a couple grams of weight daily. If I eat any type of sugar I don't put any weight on but just won't loose those couple grams daily. It's hard coz I try be strong and I'm only like 10kgs too my goal weight but it's taking it's time. What could I do or tests or foods too eat that give me that sugar hit but are not real sugar?? It's hard too live everyday without sugar!! Pls help
