For all the time that I spend praising the “miracle” of being physically active to help better manage diabetes and health, there are times when exercising does lead to better managed blood glucose and times when it does not. It is not always possible to predict the glycemic outcomes in all cases either, although individual patterns and responses can be determined over time. It is helpful to know the main factors that are predictive of outcomes.

Adequate fluid intake is essential to living well at any age, and being dehydrated can impact your health and your athletic endeavors. While it is harder to stay hydrated when exercising in the heat, you can dehydrate under other conditions—even during exercise in cold temperatures if you wear lots of clothing and sweat underneath it. As people grow older, they also begin to lose some of their normal thirst sensations, thereby increasing the risk for dehydration unless they make a conscious effort to drink more.

Is there a difference between morning (in fasting condition) vs. afternoon resistance training?

The human body only has insulin to lower blood glucose but has five hormones that raise it (with some overlap).

An increase in exercise can save your life -- in more than just heart health.

How often have you heard things about physical activity and exercise training that you thought sounded correct, but found out later they were totally wrong?

Do you need to eat a lot more protein to get bigger muscles? Confused? Here is the truth about some of the more common myths you’ll hear about being active.
