Eamonn Holmes has blamed his job as a morning TV presenter for his weight gain.
The This Morning host, 61, said he would eat six or seven meals before his lunch break as presenters "eat more" doing breakfast telly.
He started his career on GMTV in 1993 before moving to host Sky News in 2005.
Then he began hosting This Morning with his wife Ruth Langsford, 60, but the couple have now lost their weekly Friday slot and will only host during the school holidays.
Eamonn told the Daily Star : "I did 26 years on breakfast TV. It's very ageing.
"I didn't realise how much it changed my life, your habit and how you are. 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."
Eamonn added: "You eat more. You get up early and have a bowl of cornflakes at 4am, you get to work and you have a bacon roll then you might eat something on air like a doughnut then you finish at 9am and someone says 'you fancy some breakfast?'
"Then you have elevenses and you've had six or seven meals before lunch.
"You are running on adrenaline but your cortisol is all off."
Eamonn went on to lose three stone after he left Sky News and he now weighs 15 stone.
Despite the effect on his health, Eamonn said he loved doing breakfast telly.
The TV star continued: "You are nought to 60, five days a week. But all that is not good for you especially being stressed and angry and confrontational with politicians.
"It was quite tense but a dream job to wake the county up with news they hadn't known from the night before."
