Skinny as a skeleton? There's a trick called "doing sport", but calories is not something you have to be obsessed with. If you lead a healthy lifestyle, one extra ice-cream in a hot day won't hurt.
Also, there are differences between calories. The ones you want are the long chain ones, that take a lot more effort to be digested.
1k is def too low though, unless you meant "Over the recommended amount"
