Desperate

Damn, I gave in to carbs again. Had two Naan breads (together 250 cals) late in the evening. I just coudn't resist. And although I immediately went for another jog (already jogged 7 km that day, went 40 km on my road bike any hiked 7 km), I gained half a kilo! Even if this is just muscle weight due to the huge amount of sports I am doing since several weeks, I gained! But how in the world can I finally lose weight? I eat very little (only fruits and vegetables), I burn so many calories by jogging and biking, but still I gain! My metab seems to be ok, though. Do I have to eat even less? Do I have to cut down the sport? I am desperate. I must lose 5 kg as fast as possible. But all I do is gain!
