Eating a meal with no carbohydrates stops blood sugar from dropping too low after eating and keeps it within a normal, healthy range.

Eating meals high in carbohydrates can lead to a drop in blood sugar levels below the normal fasting level, resulting in reactive hypoglycemia.

The order you eat your food, mixing carbs with protein or fat, or eating a little protein or fat first might help keep your blood sugar from spiking after a carb-heavy meal.

When healthy people eat a carb-rich meal, their muscles get more blood flow and their blood vessels relax, even though their body also sends signals to tighten blood vessels—this might help their body absorb sugar from the meal better.
