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.

- Objectively measured light-intensity physical activity (100-1951 counts/min) is independently and significantly associated with lower 2-hour postchallenge plasma glucose, even after adjusting for moderate-to-vigorous activity and waist circumference.Good
- Higher objectively measured sedentary time is independently associated with higher 2-hour postchallenge plasma glucose, independent of light and moderate-to-vigorous activity levels.Good

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
