I'll say this as there is so much bullsh*t above in the form of "studies" and brash OPINION, it makes me sick.
1) The "study" above is B.S. It also utilized HIGH INTENSITY activity which you DON'T use if your goal is fat loss. (They never said how much muscle these lab rats lost doing this kind of cardio and eating before, as the study simply "ended" right there) That is a big key they left out!
2) Cardio a.m. is NOT catabolic. I see people (usually those who purchase books from the 80's at Borders and are too lazy to do 45 mins of actual productive fat burning cardio, not just calorie burning) post this sh*t all the time. NOT EATING CORRECTLY 24/7 IS CATABOLIC, NOT EXERCISE! If that were the case, I'd be a skinny little b*tch, as well as the 100's I train. NOT the case! You have to know how to eat correctly for the activity you are doing, and NOT just use half ass studies or OPINION in reasoning.
3) As far as HIIT elevating metabolism, well newsflash, so does the lower-medium intensity along with ACTUAL LIPOLYSIS!!!!!! HIIT does NOT provide lipolysis! You do not burn stored fat UNTIL 20-25 mins of 65-75% MHR, and if you only do 20 mins or so of HIIT, and are WAY OVER the MHR for the fat burning effects, you are basically burning off excess nutrients and MUSCLE GLYCOGEN as your aerobic activity is now ANAEROBIC, or without air..........YOU CAN'T BURN BODYFAT W/OUT AIR!!!!! Again, HIIT is the lazy man's cardio, but to each his own, I know how I look and why I look the way I do, and staying lean ain't from HIIT, not for me nor clientele!
4) Eating first before ANY kind of cardio is the most assinine thing to do. You may "think" you are losing fat weekly, in reality, you are burning off the calories you just ate, you are doing NOTHING for stored bodyfat, and you are merely burning up calories that can be used for bodily repair. Talk about CATABOLISM! If anything, that sets the stage better! Don't be surprised in weeks to come when you realize your weight loss was primarily of the lean mass variety.
Point is, I can post studies for BOTH sides until my **** hands fall off. You have to use your head and realize that if lipolysis (fat burning) occurs with AEROBIC exercise, then performing ANAEROBIC activity is NOT going to burn fat.
You cannot argue that point with ANY STUDY, IT'S BASIC BIOLOGY!
If you like to eat and burn off what you ate, thus not using any of that for recovery and just using it to fuel your high intensity ass kicking cardio session for endurance purposes only, then go ahead and waste time! I'll be over here at 5% bodyfat laughing.
Sorry guys, I'm tired of people throwing around "THIS IS THE WAY TO DO IT", after seeing posts earlier by the same people asking for advice only a few days ago, and now they are an expert on what they asked about?
Get real.......
Also, "I do cardio when I have the most energy"........well, sorry to tell you that ain't going to help your efforts if your goal is fat loss!
BOTTOM LINE IS NUTRITION..........If you eat CORRECTLY after fat burning cardio, you don't have ANYTHING to worry about. You can't go catabolic and ruin a physique that you have been building in 45 minutes. It takes days/weeks of phucking up royally nutrition wise to not support the exercise that makes you catabolic.
RE-CAP!
1) You need air to burn fat, period. HIIT is too intense to invite lipolysis.
(Basic biology)
2) Nutrition is the key to warding off catabolism, not the activity itself!
