I've said it many times before, but here goes again... if you want to lose weight and stay healthy, your energy intake must be relevant to your energy use. Eating and drinking sugar-filled things is not an efficient way to bump up your energy to help you exercise, or get through that 3pm slump at work. It will just spike your blood sugar levels and then drop them drastically, which is counter-productive.
Being aware of what has sugar in it is the first step to reducing your sugar intake. There aren't enough hours in my week to list all the things that have sugar in, so I'm just using a few drinks as examples for you to start with.
It may be no surprise that that Coke has a lot of sugar in it, but did you know how much sugar is in a 'healthy' fruit juice drink or an iced tea?
Don't be fooled that all water is sugar-free either. The plain water shown is what you should be looking for at the supermarket, not those flavoured waters that sneak sugar and other nasty additives in.
Swapping to 'diet' or 'no added sugar' options for lots of drinks may be no better for your overall health. The substitutes often used to make your drink taste sweet can lead to other health concerns including worsening depression and anxiety disorders.
So next time you buy a drink just take a peek at the ingredients list first. If sugar is in the first few ingredients listed then you'd probably be best off without chugging that particular option.
