Hunger depletes too fast

Ever since 1.7 the hunger features in Minecraft have been really weird. I noticed that hunger depletes way too ,oops one sec gotta eat. Anyways i noticed huner depletes way too fast when sprinting aroun, ugh, gotta eat again! Whenever i sprint and run around and try to go places i use up stacks of foo-oh one sec, gotta eat again. But long story short, hunger needs to back to pre1.6. (saying that i need to eat again).
