Many diabetics benefit from a low carb diet. For us, carbs are the enemy, especially simple carbs like those found in sugar, wheat flour, rice, pasta, breads and cereal. They're easy for the body to digest quickly and will give you more of a blood sugar spike than slower digesting foods like proteins and fats. We can't eliminate carbs altogether because our bodies need them, but we can limit them and choose foods that have slower digesting carbs (like some veggies).

My counselor gave me this plan. Everyone is different, men and women, height and weight.

Breakfast - 30 grams
Snack - (if I have one) 15 grams
Lunch - 30 grams
Snack - (if I have one) 15 grams
Dinner - 45 grams
Snack - (if I have one) 15 grams

However, I do not always have that much, but I am doing fine.

Everything in moderation!

it’s not a standard one size fits all. Go see dietician, that way you’ll know how many carbs per meal is good for you. All we can do here is let you know what we go by. As some will go by a few carbs(how ever they count their carbs) per meal, to up to 45-75 per meal.
And there are several ways to count carbs too. There are quite a few carb counting books and apps too

I try and keep my carb way under 45 gram (I average about 35)
Snacks I keep to 15 grams.
For me the higher to carb count = higher insulin dose. And I don’t want that😁
