Ok in a nut shell . . . .
Quote by MR. BMJ from the "When Does 30 + 30 NOT = 60" thread on the Womens Discussion Board: It comes down to how much glycogen you have to burn up before getting into that fat burning zone of stored fatty acids. The lower the levels of glycogen, the quicker you will get into the fat burning zone. This is why morning cardio is so effective because glycogen levels have been deplenished by the over-night fast from eating. Thus, it will vary, but 60 minutes is a good mark to set for anyone who is not in ketosis. A person in ketosis will not have to go nearly as long (thought i'd throw that in there).
Here's a tip that MS has given in the past. If you want to quicken your descent into the fat burning zone, try supplementing with ALA at night before bed and also before doing your cardio in the morning. The ALA will help deplete the glycogen within the muscle (hence, a glucose disposal agent) and get you into the fat burning zone faster. Trust me it works. Take it in the morning with your thermogenic stack (E/C/Y).
Also, to help use glycogen stores quicker, research has pointed out that high intensity intervals sessions are somewhat more effective than constant aerobic cardio sessions. Then it seems that once you are in the fat burning zone, the constant aerobic session is more effective. Don't know if that made sense but oh well.

Quote by WarLobo who created "When Does 30+30NOT=60": But one of the bigest reasons is, when you limit calories the FIRST thing that the body wants to gets rid of is the expensive MUSCLE. When you do the cardio, you FORCE the body to break down FAT because you need the enegy NOW. Then, after a your done, you feed the body and (try to) preserve the muscle.
As I have said on other threads I am not an expert on nutrition and do not claim to be I am learning just like you and I am not claiming that Cackerot69 is right nor wrong. What I am saying is do all the research you can do and find the "common ground" or "consensus" of what everyone is saying cause we are all confused when starting out (although I have been lifting on and off since 9 yrs. old) however, the majority of all the research on diet schedules that I have done (of Pro's and Amatuers) they have indicated that carbs are not good at night, and most of your carb intake should be taken in earlier in the day after cardio on an empty stomach to burn fat insted of muscle (see examples above) and that later in the evening should be geared toward mostly protein intake with many (not necessarily everyone) taking a non-caloric protein shake 1 to 2 hours before bed. I am using this whole diet approach and it is working for me, may not work for everyone but this seems to be the "consensus" among the majority. Remember to do your own research and experiment / trial and error , find the "common ground" with what works and what does not, research this board as well as other sites, books, etc.. this is how everyone has had to learn. Good Luck! Hope this helps!
