It’s not hard to believe that you need qualifications to be a nutritionist.

It's science and I remember the horror of my chemistry standard grade – it’s hard work.

What does surprise me, though, is how many people out there seem to think they’re nutritionists with little or no training.

Maybe it’s down to the internet. Nowadays we can post what we like on Youtube or social media sites. We can all claim to be experts.

The latest trend for offering advice on healthy eating and fitness inspiration – known as fitspo – is worrying, though.

Fitspo seems to be endorsing strength rather than skinniness. It’s less about looking like you’ve skipped lunch and more about appearing pumped up with muscles.

It usually accompanies a photo – maybe you’ve just finished a spin class or you’re proud of your avocado on toast.

We’re a world that likes to share so none of this is out of the ordinary.

But the obsession with healthiness is completely out of hand.

It’s healthy to have a balanced diet, to enjoy porridge and fruit as well as fish and chips.

It’s not healthy to continually post pictures of a body that seems only to be attainable if you exercise excessively and restrict your calorie intake.

One fitness blogger Celia Learmonth took a brave step in admitting to her 20,000 Instagram followers that she was “trying to get help at an eating disorder clinic”.

She regularly gives out advice on how to have a healthy lifestyle, however it’s now clear her reality is entirely different.

I think it’s really important that Celia said what was going on in her life but how many people were influenced by her?

It’s great that people are encouraged to eat better but there’s a dark side to it.

Earlier this year Australian wellness blogger Belle Gibson admitted she lied about having multiple cancers, despite releasing a book based on how healthy eating 'cured her'.

Nothing shows how ridiculous the world of fitspo is than before and after ‘transformation’ pictures.

Fitness blogger Sophie Kay poked fun at this trend by creating a fake set of pictures.

The photos were taken minutes apart – and all she did was turn off a light and twist to the side.

The stunt is a reminder that pictures don’t tell the whole story and we need some common sense when it comes to healthy eating and fitness.
