Ahhh sayang, GDM memang cabaran lah, especially when fasting numbers won't budge even after diet! A few of my mum friends who went through this ended up on metformin or insulin because diet alone tak cukup, and honestly it's nothing to feel bad about, some bodies just need the extra help, so please don't stress yourself lah. For the 3pm onwards meals, most of them kept it light with protein + low-carb snacks (like nuts, cheese, boiled eggs) at 3pm, then a proper dinner with smaller portion rice and lots of veggies around 6-7pm, timing your insulin or meds right before meals also helps with those morning readings. But honestly, check with your doctor or dietitian to fine-tune it for your body lah, because everyone's response is different, and they can adjust your medication if needed! Hang in there mama, you're doing your best for baby!
