Can dieting (longer periods of hunger, reducing carbs, etc) cause changes in blood sugar and affect the results of a HbA1c test?

In brief: Starvation

Starvation can cause low blood sugar levels.
HgbA1c reflects blood sugar levels for up to 12 weeks and thus may not change drastically in the short term. An endocrinologist can answer your question better,however.
