This ClubEqual Sweetner says that the
sweetner has 8kJ (2 Cal) per serve of 1 level teaspoon (0.5g)
than it compares it to sugar, that says it has 68kJ (16 Cal) per serve
of 1 level teaspoon.
But when I look on the sugar packet, it says it has 68kJ (16 Cal) per
serve of 1 level teaspoon (4g).

Is the sweetner still 8 times less fatning than sugar. I dont
understand, they're comparing at wrong amounts (saying that 1 level
teaspoon is 0.5 g for ClubEqual Sweetner, and 4g for sugar_. Than when
you look per 100g, the sweetner isn't even 2 times less fatning than
sugar.
