Generally speaking, the woman is supposed to "carbo-load" for several days before a GTT. This apparently stimulates her body to produce more insulin and be more prepared for the overload of the 100g test. However, many doctors do not instruct their patients on this at all, and some even forget to tell the patient to fast ahead of time. In addition, even those who tell their patients to carbo-load do not give consistent advice. Some give a specific diet to follow, specifying exactly how many extra carbs to eat and when (usually >150g--10 servings or more--of carbs per day; remember that carbs in this case includes all starches, fruits, sweets, and dairy products). On the other hand, other doctors just tell the woman to eat a few extra servings of carbs 1-2 days before the test. Be sure to press your doctor for more details on this and question your care closely if the doctor seems careless in attitude towards the test protocols. The official recommendation is to carbo-load for at least 3 days before the test, but since many doctors do not follow this, the lack of uniform testing conditions is a major criticism of this test.
Exercise also improves your levels of insulin sensitivity, so exercising for several days before the test could theoretically improve your results if you were borderline, although longer-term exercise is usually required for significant effect. Since you want to have ACCURATE test results based on your NORMAL habits, it is probably not a good idea to increase your exercise pattern significantly, though the official recommendations do not recommend restricting activity either. You want your true test results to reflect the conditions you live under on a regular, daily basis so a one-time sudden surge in exercise is not a good idea and smacks of trying to artificially 'fool' the test. If you do already exercise regularly, then you should continue in your normal patterns but not restrict activity.
For the fasting draw (before drinking the glucola), you should have about 10 hours of fasting overnight. If you have less than 8 hours, your bG may still be elevated from food the night before. If you have more than 12-14 hours, your bG may have dipped so low that the body needed to access other bodily sources of energy and the number may be falsely high as a result. Different providers recommend different fasting intervals, but the most common recommendations seem to be 9-10 hours. It may be very important to keep within this time window. Consult your provider.
You should probably eat a small bedtime snack, one that contains protein, shortly before starting your fast. This will hopefully keep your body from dipping too low between your last meal and your fasting test. For example, if your last meal is at 6 p.m. the night before and you do not test until 8 a.m. the next morning, your fasting interval will be 14 hours, and your body may already have had to access other sources of energy and your readings may be falsely high. So try to eat a small snack with protein about 9-12 hours before your test is scheduled in the morning. Protein is important because it slows down the absorption of carbohydrates, giving you a more consistent and long-term supply of energy. Otherwise, you may get a quick spike, then a crash, and then another spike as the body compensates for the lack of energy.
