This Morning's Dr Megan issued a warning to anyone looking to start a diet for the new year.
The health expert warned people starting a 'new year new me' kind of diet should go into the changes with as much information as possible, otherwise it could do more harm than good. She said certain diets such as the 5:2 diet are popular trends to try with those looking to lose weight quickly.
But speaking to ITV show hosts Dermot O'Leary and Josie Gibson, the doctor said these kinds of diets can be damaging in the long run. She often finds when people stop the diets their weight returns - plus more.
