I think it's worth a try to commute half way each day. You seem to be able to control your impulses better that way.
One alternative might be to have something ready, or nearly so, when you get home. It doesn't need to be a full meal, but maybe something like a mug of hot chocolate would keep you from chasing down the cat and stir-frying it.
I have a hard time trying to lose weight while riding a lot. My break point seems to be somewhere between 120-150 miles a week. Below that, I can (with some effort) lose weight. Above that, I lose energy, so I eat carbs; even though I track them all, I either maintain my weight or creep up a bit. It's a hard choice -- increase my speed and endurance, becoming a better bicyclist; or take off weight so I can climb better, becoming a better bicyclist. Choose one. (Or have a pumpkin spice Krispy Kreme doughnut, choice 3!)
