Labels might be 20% off or even 50% off, but still give you ballpark figure, and is better than nothing. I haven't had patience to precisely track calories, but I find it enlightening to look at labels and compare. For example, my intuition tells peanuts are more calory-dense than carrots. But by how much? Oh, 14x! That's good to know--1kg of raw carrots might barely cover one meal, but 1kg of peanuts would power me for 3 days--careful!
