I live next to a shop that squeezes fresh juice, but I mix it with at least three parts carbonated water. Otherwise it's such an easy way to overconsume calories. And possibly the least fulfilling way, as well.
It's not at all hard and as prviously stated, fruit juices contain at least as much sugars naturally.
When I lived in Seattle, I always found it amusing that soccer moms would brag about buying Mexican Coke at Whole Foods like it was something special. They could just drive an hour north and buy Canadian Coke, which is also made with sugar, for half the price!
This is true. That's why in baking, sugar is considered a liquid, not a solid.
