You can get a low blood sugar by not consuming enough carbs, but also by eating too many carbs, creating excess glucose, and your body overproducing Insulin, which lowers blood sugars.
Most people do not get low blood sugars ever though. Are you diabetic, or hypoglycemic? If not, what makes you think you are having a low blood sugar? If measuring it with meter, how low?
Then you need to use your food tracker, and make it public. It is hard to give advice without it.
I do want to say that many people who drink shakes, or liquid calories, tend to have blood sugar spike, then rapid drops, as the body produces Insulin. It is natural, the body just working correctly. If you are going to eat like this, you may have to switch to 5-6 meals. It is also the reason, you should have some fat/protein along with each meal, to avoid huge spikes.
