Ya, I dunno. I spend 3-5 hours lifting and 12-20+ hours a week on my bike training. I can still quickly gain weight and you don't present the ultimate difficulty, training makes you really fucking hungry. I burn 1000 KJ/hour average on the bike and I can undo that real quick, 150kcal/day is a small handful of chips.
I'm extremely dubious of any answer to weight loss which isn't get your diet in line.
