Multiple workouts a day = higher metabolism?

I think this is a great strategy to keep your calorie furnace burning, especailly considering your fueling yourself with several small, healthy meals. Everytime you bump up your HR and have a little snack in between, you'll boost up your metabolism greatly. As far as having those effects carry out into the next day is another story. Considering your workouts are aerobic - that burn boost will only last so long before it tapers off. However, if you substitute a little bit of strength training in your workouts the increased rate at which your body uses up calories will be prolonged significantly (like 24-36+ hours long as your muscles rebuild). I used this approach with some of my training - morning lift session and an evening areobic session. I saw great results and ate like horse (which is everyones goal right?)

In essence, yes, you were probably unsatisfied until lunch due to all the activity you were doing prior. So don't be afraid to eat more earlier as long as it doesn't interefere with the comfort of your training. This will also keep your meals smaller in the P.M. which helps weightloss.

Btw, You did you eat a dinner that day, right?   

Yep definitely had dinner and afternoon tea that day but can't remember what.

Come to think of it the quantity of food wasn't that much more than a typical training day. I think it was just that I got hungry so quickly in between that really stood out.

Cheers for the feedback
