    Say I know I have to eat ... 2000 calories a day. If a food is listed as having 430 kcal, does that mean 430 thousand calories? Obviously not, but what does it mean?

    1 calorie is the energy required to raise one cc of water 1 degree celsius (or 1 gram of H20 - whatever you prefer).

    A Kcals is usually written as 1 Calorie.

    All sport and food related activies are usually measured in Calories, but people mistakenly write them with a small "c".

    For scientific purposes you might want to work with a finer level of detail such as calories. This is largely impractical in day to day fitness and dieting.

    Yes, Calories are roughly a quarter of Joules. Don't know how to work out WW points, they are based on a combination of calories and fat grams, so all chocolate would be high. Nuts and salmon are also very high!
