Wow. I covet your energy! ;-D
I would be concerned about a couple things. First, hydration. Not necessarily when you're exercising, but afterward. We keep burning for almost an hour after intense exercise so even though you're back doing your daily routine, your body is still pumping. That's the time we have to really replenish our bodies. The biggest obstacle for a lot of people in weight loss is dehydration. The balance of salts (electrolytes) in your body effect your hormones which effect just about every function of your body. When you don't have enough h2o in you, your bodily systems don't function according to manufacturer spec. Not only will you retain water, you won't be removing important toxins as effectively from your system which can add deceptive bulk. It doesn't take much dehydration to start throwing your body's delicate chemical balance off.
The second thing I would be concerned about is nutrition. I looked at your diet calendar and I think it's great that you want to build wiggle room into your diet. It's realistic. But if you're going to push your body that hard, you have to support it. At best it won't cooperate in your efforts because it thinks it's some kind of zombie apocalypse famine where you run all the time and it doesn't get all its nutrients. It will horde everything you put in it. At worst, a body that isn't fed doesn't function so you're taxing your organs, your hormonal systems, your immune system... Are you taking any supplements?
It's been proven that a combination of cardio AND weight training is the most effective way to lose weight because you're burning fat two different ways, thermogenically (cardio) and metabolically (strength training). I'm sure you've heard that muscle burns more than fat. It burns all the time, even when you're asleep and is the key to increasing metabolism. If you're looking to maximize your weight loss you would really benefit from some Resistance training. Working with bands or your own body weight will create long, lean muscles that will not only burn calories but will also make your weight loss look even better. I would look into yoga and Pilates, or ask a trainer at your gym to show help you craft a workout with resistance bands. A little muscle can make a *world* of difference!
Keep up the great work!
And then the day came, when the risk to remain tight in a bud
was more painful than the risk it took to Blossom.
