He not only gained lots of weight, going from from 168 to 192 pounds, but other negative side effects also included a soaring blood pressure, intense sugar cravings and loss of appetite.

As well as the fast weight gain, Mr Prior, a father-of-two, said he feared he was becoming addicted to Coca-Cola after experiencing intense cravings.

While he tried to stick to his normal Paleo diet – a low-carbohydrate diet which focuses on eating lean meats, vegetables and berries – he began experiencing sugar cravings that were difficult to ignore.
