With the UN warning sugar could be ‘the new tobacco’ because of its risks to health through obesity, you might think a diet that cuts it out would get the thumbs up from experts.
But a group of scientists has just consigned a trendy sugar-free anti-ageing plan to a list of fad diets it dismisses as a waste of time and money, and potentially dangerous, The Daily Mail reports.
While dieters can forgo sugar in yoghurt, ready meals, dessert and biscuits, for example, having none at all is almost impossible.
‘Cutting all sugar from your diet would be very difficult to achieve,’ said biochemist Leah Fitzsimmons, who even warned that such a drastic approach could be fatal.
‘Fruits, vegetables, dairy products and dairy replacements, eggs, alcohol and nuts all contain sugar, which would leave you with little other than meat and fats to eat – definitely not very healthy.’
They also dismissed the caveman diet, said to be favoured by actor Matthew McConaughey, which holds that because we evolved eating a limited number of foods, we should return to our evolutionary roots and eat berries, vegetables and lean meat, while eschewing modern fare such as cereals, lentils, beans and dairy products.
Also rejected were diets that claim to selectively slim parts of the body by influencing hormones.
The bizarre clay diet was also considered a health risk. Its followers believe a spoon of clay a day detoxifies the body, boosts the immune system and balances acidity levels.
However, dieticians warn it can cause problems from constipation to poisoning and say ‘detoxing’ is a marketing myth.
