In his column, he recalled the time he and Eamonn fell out after Piers branded him a “teletubby” during his time as the editor of the Daily Mirror newspaper.
Now eating his words, he said he wouldn’t mind looking like his former Breakfast TV predecessor after putting weight on himself.
After sharing his latest column on Twitter, Eamonn replied to Piers, telling the latter he could be his weight loss “mentor”.
He wrote: “I could be your mentor… know all the mistakes u r making.(sic)

“I was three stone heavier when I was on GMTV than I am now.
“The pictures of me in my 30s and 40s, I just can’t look at.”
Piers said of Eamonn’s comments in his Daily Mail online column: “I can totally relate to this.
“My own Good Morning Britain day regime is usually porridge and honey at 5.30am, Marmite on toast at 7.30am, eggs and something when I get home at 9.15am, possibly another sandwich snack at 11am, and a hearty lunch at 12.30pm before attacking the biscuit tin in the afternoon, until my wife Celia locks it away.”
Piers went on to say he had been tweeted by a viewer about the amount of tea he has during the show.
“She [the show’s runner] said I have seven mugs of tea while Susanna [Reid] has TEN mugs of tea and black coffee. And that’s just what we consume before 9am!”
He went on to say he currently weights 16 stone, a stone heavier than when he first started the show in 2015.
“So my resolution is to weigh the same as Eamonn Holmes by the end of 2021,” he concluded.
Good Morning Britain airs weekdays from 6am on ITV.
