tbspn of olive/flax/ oil before fasted cardio?

[Bobby]

Will taking a tablespoon of flax oil before fasted cardio ensure that once that little bit of flax oil has been used, the body will use stored bodyfat as the fuel source for that cardio session?

and similarly: will taking some whey mean that once the whey is used the body will use stored muscle protein for fuel?

 

[candidizzle]

 yes to question ONE (fish oil would be better though)

NO to question two (however, whey can cause a bumpi in insulin levels which would slow lipolysis a little bit)

[ScottWelch]

No to both. 

If the intensity of the cardio session is too high, the muscles will be fueled primarily by stored ATP + CP and from glycogen (not fat).  Only if the intensity is low enough and long enough can a significant % of calories come from fat for any activity.  In the case of fats fueling cardio exercise, the fat must come from stored intramuscular triglycerides specifically located within the muscles doing the contractions to propel the body during your cardio session.  These intramuscular triglycerides take hours (not minutes) to form and as such, would not be formed fast enough from a pre-workout meal.

the moment the omega 3 enter the blood stream your body should recognize them and the homronal changes would occur and youd get the better fat burning effects.


thaTS HOW I UNDERSTAND IT, AT LEAST (AND THATS HOW IT SEEMS TO WORK FOR ME IRL)

didnt mean for the caps lock..

In other words for cardio you want decent intensity for longer periods of time to tap the fat storage??
