Carbs have a terrible reputation, but they are vital to a healthy diet PICTURE:
Cut out of countless diets, carbs are seen by many as enemy-number-when when it comes to maintaining a healthy weight.

Regimes like Atkins, Dukan and the Blood Sugar Diet feature little or no carbs, with the promise that this will help a person shed and keep of unhealthy bodyweight. And now that anyone can set up an Instagram account and call themselves a fitness and food guru without any qualifications, there is more misinformation being fed to people than ever before. 

But the truth about carbs is a lot more complicated than simply labelling them as "bad" and binning them forever, according to dietitians. First off, carbs are often used as a by-word for foods such as potatoes, bread and pasta. In actuality, carbohydrates are broken into three subcategories: sugar, starch and fibre. Fruit, vegetables and milk fall into the ‘sugar’ category; starch includes rice, bread and potatoes; while fibre is found in whole grain breads and pasta, and pulses. It’s refined carbs, from white bread, pastries, confectionary, cakes and sweets that we need to be careful about eating too often to avoid weight gain, diabetes and other chronic diseases. 
The issue isn’t carbs, but our portion sizes in relation to how much we move, explains dietitian and BDA Spokesperson, Aisling Pigott. 

“We should all be paying more attention to appropriate amounts of carbohydrate in our diet, not because they are ‘bad’, but because we need to eat the right amount for our body. No food type, whether it be fat, protein, carbohydrate or even vegetables is wholly good, nor wholly bad. It is part of our nature to sensationalise things, and we struggle with this concept of moderation,” she adds. 
Researchers found that frequent fried potato eaters more than doubled their risk of a premature death.
The good news is that people who have followed a diet low in starchy carbs aren’t harming themselves particularly, but they are probably making their lives harder than they need to be. 
“Generally, for healthy and well people there is little physical danger other than constipation, bad breath and mood-swings in following a low-carb diet,” says Pigott. “As a dietitian having seen various fads over the years, I would argue there is a psychological danger.” 

At first, a diet low in starchy carbs will get rid of water retention in the muscles - which isn’t actually a sign of fat loss. A long-term diet free of starchy carbs might cause a drop on the scale, but keeping it up is the hard part, says Pigott. 
“The removal of starchy carbohydrate from the diet in people who already have a difficult relationship with food can actually lead to increased risk of binging and overeating,” she warns. 

By cutting out all carbs - not just the refined kind - we lose an important source of B vitamins and soluble and insoluble fibre, which aid digestion, warns BDA Spokesperson Anna Groom.
