I would advise you to definitely do something about it...
You may be slim now, but the rate of becoming fat can be so slow, that you barely even notice until it's too late.

Then one day you'll look in the mirror and realise you look nothing like you used to.

Six bars of chocolate a day = 600 - 1200 calories, depending on what exactly you're eating. And sometimes you're eating more.

The recommended calory intake is 2500 a day at most, preferably 2000.

So you're taking up a large percentage of your daily intake just on chocolate, nevermind any other snacks/meals you might have.

A pint glass full of pure orange juice is roughly 200 calories, so literally every little thing adds up. Milk/fizzy drinks are much more, so even your daily drinks can make up almost half of your daily calories.
