Fasting plasma glucose (FPG) is not significantly associated with objectively measured light-intensity or moderate-to-vigorous physical activity after adjusting for confounders like waist circumference.

Do not rely solely on fasting blood sugar tests to judge the effectiveness of your exercise routine. Your body's ability to handle sugar after eating (2-hour post-challenge glucose) is a much more sensitive indicator of how physical activity is improving your metabolic health.
