According to this thing, you're fine.
That chart says I'm close to the size of cyclist Krisztián Lovassy. Close enough.
Actually, I could stand to lose 3-5 lbs to be at optimal weight for competition. But I'm not competing so I'm not worrying about it. And if I did lose another kg I'd be the same size as fencer Anna Bentley.
I snack a lot too but I try to keep healthy stuff around. Try. I don't always succeed, but I've cut way back on the sugary stuff and junk carbs like beer and wine.
