With Christmas Day just a week away it is that time of year when many people overindulge in food and alcohol only to regret it early January when jeans are too tight and you are bigger than your beach towel.
It is then that the diet industry piles in with enticing claims such as "bikini body in 28 days" or "lose 10 kilos fast".
If the paleo diet was the trend of 2016, could 2017 be the year of the potato diet?
This week it emerged a man who ate nothing but potatoes for a year lost more than 50kg and, not only that, said he was a changed man.
For a whole year he ate about three to four kilograms of potatoes each day, saying he would eat them in every way - from boiled to mashed to baked. He even created potato pancakes.
