As one of the nation's funniest women, it's possible she wasn't being entirely serious.
But size 20 comedienne Dawn French has told how she has a medical disorder called 'body blindness' that stops her wanting to lose weight.
The 51-year-old told a women's magazine that she ignores health warnings about obesity.
Comedy: Dawn French said: 'Sometimes I'll get out of bed and think, "Oooh, I need to do some exercise" - but that's probably about once a year, if that'
'I can honestly say that it doesn't bother me, though I do worry that I'll get so comfortably fat that I won't be able to walk any more,' the French And Saunders star told Woman's Weekly.
'Sometimes I'll get out of bed and think, "Oooh, I need to do some exercise" - but that's probably about once a year, if that.
'I think the medical term for my condition is called "body blindness". I may ultimately regret not looking after myself more, and plenty of people would line up to tell me that, but it doesn't concern me.'

French, who also starred in BBC comedy The Vicar Of Dibley, is just 5ft tall yet was already a size 16 at the age of 13.
She was left feeling tired and ill when she took a cocktail of pills and slimming injections to drop four dress sizes and fit into a size 12 wedding gown in a matter of weeks before she married fellow comedian Lenny Henry in 1984.
According to Dawn, her husband of 24 years is happy as long as she is which means accepting her voluptuous figure.

'When we got married I lost a lot of weight in a very short time, all because I panicked that I shouldn't be a fat bride,' she confesses.
'But Len took me to one side and said, "Who are you doing this for? I hope it's not me because it's not what I want."
Dawn has said in the past that Lenny loves the fuller figure - especially in the bedroom.
'Big women do sex fantastically well. We know how to use our mighty weight and know the considerable power of a full and voluptuous body.
'My husband's Jamaican and comes from a family of big women. For him it's the norm and thin women are a turn-off.'
The Vicar Of Dibley star, was said to have been dropped as the face of Terry's Chocolate Orange after ten years because her weight made her an undesirable role model amidst fears over increased obesity levels.
But the chocolate-loving star is not about to reach for the diet drinks anytime soon.
'Losing weight made me miserable and I was so cross with myself afterwards.'
Earlier this week a doctor warned that chubby celebrities were fuelling the obesity crisis and setting a poor example.
Dr David Haslam of the National Obesity Forum said that he had never heard of 'body blindness' but said some people simply did not care about obesity.
He warns that such people risk developing diabetes, cancer and a string of other diseases.
'There are a lot of people who are simply happy to carry around a lot of weight; it's called fat acceptance,' he said.
'I find this difficult to accept purely from a health point of view, not an image one.'
Michael McMahon, an obesity expert and surgeon, said the high profile of larger stars such as TV presenter Eamonn Holmes, comedian Johnny Vegas and singer Beth Ditto has shown that being plump is no barrier to success.
Professor McMahon said: 'If people continue to turn a blind eye to their weight problems, they will see their life expectancy considerably shortened.
'The new research suggests that if the rise in obesity continues at this rate, the majority of the British population could be obese before the turn of the century.
