The 58-year-old presenter was told by a weight loss expert that he was in danger if he didn't change his ways.
Weight loss expert Steve Miller and plus-size model Gemma Cruickshank appeared on Good Morning Britain to discuss fat-shaming in today's society.
Miller was an advocate of being frank with patients on how much weight they have to lose and said that honesty is the best policy in discussing weight gain.
In discussing the case of Eamonn Holmes, presenter Kate Garraway asked Miller "What would you say to Eamonn?"
"Eamonn comes in and says he's got a bit of a sore throat, whatever, and he's having tummy ache or whatever your moan might be," she added.
Holmes suggested: "Your life would be improved if you lost two-and-a-half, three stone."
In reply, Miller said: "I would say that, but I would also say to Eamonn that he is too fat and he is a heart attack waiting to happen."
What do you think the right approach is to aid weight loss?
