9. Sugary Soft Drink.

Surely it's great that soft drinks come in diet form? The same drink with virtually no calories. But a 2005 study from the University of Taxas found that in a group of 622 participants studied over eight years, those are regularly drank diet soft drink were far more likely to become overweight or obese than those drinking the same amount of non-diet drink.
Alrhough artificial sweeteners may taste the same as sugar, "your body may not be fooled that it's received the same calories - so it craves more", says Jacqui Lowdon, a spokesperson for the British Dietetic Assosiation.
Diet soft drink may also lull you into false sense of security. Some people feel that if they drink one, they can have a Mars bar," says Lowdon.

BUT WATCH OUT!!.
To loss weight, you still have to cut down on calories. "Have one sugar drink a week and enjoy it, rather than a lot of diet drinks that don't satisfy you," advises Lowdon.
