I asked a carb backloading question a while back and I am so glad to see you bring it up again - with the ANDRO stamp of approval!
Keifer's site has a bit more on this. I've also looked into his carb nite solution.
I've been saving carbs for night time, using resistance exercise as well of course and have noticed the following - smaller waist size, better sleep and interestingly better skin quality. Also, I am finally making gains in the squat deadlift department - the quest for booty continues.
I am interested in leptin control, I have been following Dr. K, I read Rosedale, I also read the blogs like Keifer's and T-Nation, etc. to get their take. I am starting from a place of senstivity, so I guess the evening carbs prolly work well for me because of that. Also, the training, I train pretty heavy.
IFing doesn't work well for me - I think fasting maybe does weird things in women - but that's speculation. Dr. Eades likes to say a high fat/protein low carb diet mimics starving, without the calories restriction. So, I've not been fasting during the day, rather I've been eating vlc until night.
I don't know if this adequately addresses your question, I was just excited to see this topic again :)
