early morning fasted or post workout cardio?
which is best? I know this has been talked about many times but just like to refresh some opinions on this,i read recently that evan centopani does cardio half hour after eating a meal,cause he said something about cortisol and fasted cardio? OPINIONS PLEASE.

You wont get a straight answer to be honest. Aceto and Dave both like fasted cardio I believe. Layne Norton did a study and said it doesnt make a difference and eating may actually help.
Some people like a small amount of protein 1st. Id just advise you to experiment and see what works for you. Ive trained and done cardio fasted in the morning and made gains. Now Im having shakes before the gym because I dont like eating food early, no appetite.
Its probably easier to do cardio post workout, thats what I do...I dont have to sweat up 2 pairs of clothing a day either...the fat comes off just as well from my experience as long as Im doing cardio. I went from portly to drop dead gorgeous Yes Im male lolLast edited by Diggy; 03-02-2012 at 06:28 AM.

Well said.
Layne on the subject:
" new article on fasted cardio appearing in the Strength and Conditioning Journal by Brad Schoenfeld, MSc, CSCS
I put the full text below for those who are interested. For those that are lazy to read the whole thing here are the cliffs:
-research has shown no difference in total fat loss between subjects doing fasted cardio and those doing cardio after eating.
-fat burning consists of 1) liberating fatty acids from adipose tissue through lipolysis and then transport of those fatty acids to other tissues like muscle, liver, heart where they are then 2) oxidized for energy. When you eat before cardio you reduce lipolysis but it ends up not making a difference because lipolysis is NOT the rate limiting step of fat loss when it comes to cardio, it is oxidation that is rate limiting so you end up oxidizing the same amount
-you may burn MORE fat over a 24 hour period when you eat beforehand because there is a GREATER thermogenic response to cardio as opposed to eating fasted
-Lemon et al. demonstrated nitrogen losses were DOUBLED when you train fasted. Fantastic for maintaining muscle in a caloric deficit... NOT
-not eating before cardio will reduce training intensity and means you will burn less calories during cardio because you won't have as much energy.

Summing Up the Research Findings
• In acute trials, fat oxidation during exercise tends to be higher in low-intensity treatments, but postexercise fat oxidation and/or energy expenditure tends to be higher in high-intensity treatments.
• Fed subjects consistently experience a greater thermic effect postexercise in both intensity ranges.
• In 24-hr trials, there is no difference in fat oxidation between the 2 types, pointing to a delayed rise in fat oxidation in the high-intensity groups which evens out the field.
• In long-term studies, both linear high-intensity and HIIT training is superior to lower intensities on the whole for maintaining and/or increasing cardiovascular fitness & lean mass, and are at least as effective, and according to some research, far better at reducing bodyfat.
• 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 see the bottom line like this.. Do the type you have a personal preference for, and also respect your physical limits. HIIT is quicker but riskier. LISS is safer but takes twice as long to accomplish the same thing. Again, do what you prefer & can tolerate, but do NOT make the mistake of assuming that LISS burns more fat. That's misunderstanding the physiology of the matter.
I’ll end off by challenging you to diligently review the facts before blindly latching onto the myths.
Personal preference, but research does show that is does not really hold benefit.2013 & 2014 RX Member of the Year

Fasted is nice just because your glycogen depleted and blood sugar/insulin is low right out the gate, so body fat is the next source of fuel in line to be used during cardio. I have done cardio after meals (though I would experiment after hearing from Evan C.) and noticed I did sweat more than fasted cardio and my heart rate would go way higher. I would rather do both cardio and weight training in separate sessions to give my body several "jolts" around the day than doing it all together back to back in 1 giant session.., really jacks up your metabolism getting a kick every 6-12 hrs, also more time for recovery in between. Get your cardio in when you can, its still benficial to do it post-workout or after carbs in your system, but the ideal situation would be in the morning or before bed low insulin levels and separate from your weight training.

I've done both with no reall differences other than the fact that I am hungry all day when I do fasted cardio first thing in the morning. Due to schedule, I now do fasted on the weekends and post work cardio during the week and I am getting leaner than ever before.

I like diggy's response. Especially about having to sweat up 2 pairs of clothes. Also if you don't have any cardio equipment, then you have to travel to the gym, and get back which adds up by the end of the day, is it realistic to do that week in week out?

morning fasted cardio always made me feel more weaker and tired through out the day.
not exactly sure...maybe im gay and i just dont know yet.
i prefer this now since last month: 1/2-1 bottle of odwalla farms juice puree. then 30-45 minutes later i hit the local park and run 1-2 miles non stop....yes run....i even throw in fast burst of sprints and run laterally. 3 to 4 times a week.
currently 5'11 and 245 lbs with 20-22 % body fat Endomorpher (thank you taco bell!)
As I get leaner. I plan to up the carb intake.
I just miss running guys.... i feel like an indian ravaging through the woods looking for a white she-devil to fuck...WHERE IS SHE!!!!
keep your cunning warrior spirits up and blast that fat off like a nut!!!Last edited by Friendly Milkshake; 03-02-2012 at 12:36 PM. Reason: Reason for Ediiting:
