Ways to lower my blood sugar level?

Lower your carbs fruits some veggies and of course breads and pasta. I went and saw a nationalist yesterday because I am not happy with my weight gain anyhow what she gave me for a diet was for a woman with gestational diabetes as per the women on here and my mom who is diabetic agreed with the women on here. I do not have it but I guess because my mom does they want to prevent it who knows. She told me for breakfast, lunch and dinner I should have no less and no more than 45 grams of carbs and snacks (two a day) no more than 30 grams so maybe you can try that. Me I am going to try the diet however because I do not have it I am going to just stay away form junk food and fast food and walk like I have been Good luck oh also no sodas
