I ditto that you need more for breakfast. I'm also on weight watchers, but I have to give it up during the summer while I'm riding a lot. First of all, don't forget you gain muscle and lose fat--this results in smaller measurements but may look like a weight gain on the scale (and don't forget water retention in this heat!) Muscle weighs more than fat, but is leaner.
I went through this with my sister and a gf. You need more protein for breakfast. I like a 2-egg & hash brown scramble pre-ride, but have been settling for egg beaters in the microwave--in an attempt to get out before the heat. Small orange juice and cup of coffee. It makes a huge difference for endurance.
Cytomax in my camelbak also helps me get in calories during a long ride. For the first time last weekend, I passed up my normal mid-ride smoothie and post-ride Pepsi. They didn't even sound good. I also like Naked juice or a homemade smoothie post-ride--it's a quick, filling solution as I walk through the door
