Fasted Morning Cardio...

tigersword

In the mornings definitely eat something before weightlifting.
Its not as important and maybe even preferable to not eat anything before morning cardio.



Pretty sure that this and my earlier post are not myths.
Theyve been accepted for some time.

Just because they've been accepted, doesn't mean they are true.

Summing Up the Research Findings

• At low intensities (25-50% VO2 max), carbs during exercise reduce fat oxidation compared to fasted trainees.
• At moderate intensities (63-68% VO2 max) carbs during exercise may reduce fat oxidation in untrained subjects, but do not reduce fat oxidation in trained subjects for at least the first 80-120 minutes of exercise.
• Carbohydrate during exercise spares liver glycogen, which is among the most critical factors for anticatabolism during hypocaloric & other conditions of metabolic stress. This protective hepatic effect is absent in fasted cardio.
• At the established intensity level of peak fat oxidation (~63% VO2 max), carbohydrate increases performance without any suppression of fat oxidation in trained subjects.

I work out on an empty stomach sometimes and have no problems, but if I have eaten, I cannot workout for at least an hour and 1/2 or I will be pukey. I think everyone is different.
