It doesn't much matter which you use (kj's or cals) so long as you're consistently adding up the same type (don't go mixing cals and kj's - it's mixing apples and oranges)

I don't think you've been counting in kj's, or if you are reading kj's you've not been eating the portions you think you are. If you were having 2500kj's per day, that's around 600cals which is nowhere near what you need to be eating and you would definitely be feeling unwell. It's also nowhere near what it sounds like it should be given what it sounds like you're eating (in fact one of those muesli bars is about 130cal (540kj) and the noodles are about 300-400calories, 1 "piece" (not sure how big that is) of fruitcake might be about 140cals?). If you're eating 3 meals per day plus 2 snacks, there's no way you would be as low as 600cals in one day unless all you're eating is lettuce and celery, literally.

I don't count cals or kj's because I simply can't be bothered, but I do check them for nutrition and energy content to make smart purchases. To do that you need to know how to read one. When you read a nutrition label you need to look at the serving size, the kj's or cals per serve and I usually look at the "per 100g" for comparisons with other products whose serving sizes might be different.

You can do this one of 2 ways. Only eat in the serving sizes given (these will be much smaller than you think I'm betting, you've probably been adding up the cals for "one serve" but have actually been eating the equivalent of 2 or 3 serves) then tally up the serving size cal/kj values.

OR measure the amount you're eating and then work out how much cals/kj's are in that based on the 100g kj/cal value.

There are also calorie counting diary programs out there that will help you figure out how many cals are in what you've actually eaten, I just can't be bothered with them to be honest. Lots of people swear by them though.

That's the most basic way to use nutrition panels. Once you get that down pat you can start doing complex things like comparing percentages of different types of fat, and sugar etc

The other thing to bear in mind are liquid calories - things like soft drinks, coffee/tea, juice, sports drinks, milk drinks etc etc...

Yup. The other tricky thing they do is give you the per serving size and it's, say, a king size mars bar (just as an example). So you think "cool, there's 600 (for instance, I don't know what it would actually be!) calories in my mars bar, I can do that".

BUT if you check a little bit closer they might have on the label "servings per package: 2" - i.e. one serving is 1/2 a king size mars bar. So you can double that calorie content if you are like me and couldn't possibly just eat half a mars bar.

This is why the first weapon in your weight loss arsenal is KNOWLEDGE. Knowledge is power. Go google how to read nutrition labels, there's plenty of info out there. like this: http://nutrition.about.com/od/recipesme ... labels.htm

There might even be a post on here somewhere
