You can become a decent middle/endurance runner(up to 10k) on a regime of running 25-40 mins at a session. Either continous runs or intervals.
Long runs always made me super hungry and I tended to overeat to compensate. Whilst I was never overweight if anything I always put on a couple of pounds in these phases.
The leanest was when I mixed endurance/intervals/weights. And no feelings of vast hunger.
2 hours cardio is just daft unless you are a true marathon type, and only just. Sort out the diet and mix up training a bit. It almost sounds like chaos is the plan,
