How long have you been doing the low carb? Low carb diets can be great for fat loss, but there are plenty of different "versions" of low carb plans that work better for different people. What I'm getting at is, do you think you need to be that low?
So the only exercise you're doing is two cardio workouts and one or two weight training workouts, whereas you used to lift more often? I think we just figured out why you've plateaued. "More training = more fat loss" isn't necessarily true, but right now you're really on the far end of the spectrum in terms of doing the bare minimum for exercise.
It's not that hard to figure out even three good days of lifting to compliment the cardio work.
But really though, I get that it can suck waking up early to train, but tons of guys get it done. It's one part willpower, one part determination, one part telling yourself to just fucking do it because the results are worth it. Coffee, espresso, No-Doz, whatever it takes to prop your eyes open wide enough to shuffle into the gym.
And again, if we look at revamping your approach to nutrition, having some carbs right before and during your workouts would probably go a long way to helping this anyhow.
