I think you're on the right track. You have to get your carbs down low enough so that it doesn't affect your blood sugar and you can continue to lose weight. You might be able to go a little lower, but that's up to you. I struggle to get below 50 net gms/day.
I've got PCOS and I'm a type 2 diabetic. I usually have more blood sugar level issues with carbs in the morning than the afternoon, so I eat under 10 gm of carbs at breakfast. At lunch, I pack on the vegetables, along with protein and fat, so around 20 gms. That usually includes an avocado. For afternoon snack, I'll have yogurt, a handful of almonds, maybe a single serving of fruit on occasion, so around 30 gm. And at dinner, again with the veggies, meat and fats, and if I'm really hungry, I'll add a sweet potato, so around 60 gm. That's 120 gms. I usually subtract the fiber grams from that, so a net total of 80 gm.
I'm taller than you and I have a lot of muscle I've developed and am continuing to work on, and eating some carbs is an important part of the energy delivery system for muscle growth. However, if I go too high, like over 150 gm a day, it really impacts my blood sugar levels. I am not on any medication to manage my blood sugar. I do it all with diet and exercise. And with regards to carbs, I stay away from all refined carbs. Best to eat carbs that are combined with plenty of fiber, plus add some healthy fat to slow the whole digestion process down and not have such an impact on bloodsugar levels.
