It is the feel-good hit show that is viewed by up to six million viewers every week.
But The Great British Bake Off should kick off every episode with a warning for obesity, an expert said.
Steve Miller, a weight loss guru, said Channel 4 should hammer home that the sugar-laden food they put on screens can & # 39; make us fat & # 39 ;.
Seeing such tempting cakes can get fans & # 39; off the rails & # 39; if they are not paying attention, an obese charity warned.
But critics managed to reject the claims and said it is clear that the show represents cake as a one-time treat, and demonizing food is not necessary.
The controversial comments are in the midst of an obesity epidemic in the UK, where two-thirds of adults are overweight or obese.
Content on TV has shown that it influences food choice, and studies that prove that food advertising is possible can lead children to eat more junk food.

Weight loss guru Steve Miller said that Channel 4 should not hit eggshells when it comes to tackling obesity and informally remind viewers of the risks of excess cake
Miller, who gives consultations for weight loss online from his home in Solihull, said to MailOnline: & I think we should get a warning during the show.
& # 39; Or perhaps the presenters can informally let us know that eating too much cake can make us fat.
& # 39; They should not be afraid to say so. We are entering eggshells when it comes to tackling obesity.
& # 39; Let's keep ourselves aware of eating too much sugar – which is claimed to be the & # 39; new cocaine is & # 39; because it is so addictive. & # 39;
Miller added: “The country needs to know if you get too much sugar, you risk cancer and heart disease.
& # 39; I am not a snowflake but a hailstone. I say we shouldn't bury our heads in the Victoria sponge. & # 39;
It is not the first time that Mr Miller has slammed GBBO – he controversially said last year that the program should be completely banned.
Viewers were indignant about his comments, which he now admits perhaps & # 39; exaggerated & # 39 ;.
Tam Fry, president of the National Obesity Forum, said that GBBO is inevitably viewed by people with their mouths wide open.
He said: & # 39; People are stuck with a program that consists of sugar and sweet things in abundance.

& # 39; If they make that food and eat it greedily and don't train, inevitable weight gain follows.
& # 39; You need to be wise if you look at this type of program to avoid being overwhelmed by the opulence and then get off the rails. & # 39;
OBESITY & IT IS NEW SMOKING AND WILL ROCKETING CANCER PRICES & # 39;
Simon Stevens, CEO of NHS England, said he expects obesity-related cancer cases to double by 2035 because so many people are fat.
In 2015, 22,800 cancer diagnoses were linked to the weight of the patient and he expects this to rise to 40,800 within just 16 years.
& # 39; Although cancer survival is at a record high level, many people do not yet realize that obesity causes cancer & # 39 ;, Mr. Stevens warned in May.
& # 39; According to current trends, we see 100 new patients with obesity-related cancer every day in 2030.
"So obesity is new smoking, and if we continue to accumulate, we go to thousands of more preventable cancer deaths every year."
About 64 percent of adults in the UK are overweight or obese, in addition to nearly a third of children.
In addition to an increased risk of cancer, fat also makes people more likely to develop type 2 diabetes, heart disease, joint problems or a stroke.
Dr. Jennifer Ligibel, expert at Harvard University, said: "Obesity is now one of the greatest challenges facing the world.
"The US has more obesity, but the UK is catching up. It is very disturbing.
& # 39; We are making great progress in cancer therapies and treatment, but the risk is that obesity can undermine all of this. & # 39;
Although Mr. Fry said the show could tempt people to eat cake, it would suggest that change would be too extreme.
He said: & # 39; One series is not going to make a difference to the problem of obesity. Over time, however, they have done many series that may have an effect.
& # 39; But the answer to the problem of obesity is much broader. & # 39;
Professor Jane Ogden, a psychologist at the University of Surrey, said that demonizing food only makes people rebel and craves more.
& # 39; The healthiest relationship we can have with food is not to see it as simplistic as good or bad, & # 39; she said.
& # 39; It's all about modest food. They don't say they should have it for breakfast, lunch, and dinner.
& # 39; They say we should do it right and make it ourselves. It puts cake in its rightful place in our diet, as a special treat. & # 39;
Professor Odgen said that GBBO can even inspire people to go into the kitchen and celebrate learning new skills.
She added: & # 39; Regardless of what is on the TV, TV changes the way we eat because we can eat more thoughtlessly.
& # 39; TV ads make us want to buy the food. And there are indications for this with children. & # 39;
Exposure to junk food on television has been associated with weight gain in children through advertising.
It can cause children to eat and change their food preferences immediately after seeing an advertisement, a study by Cancer Research last year.
The charity said that viewing one additional junk food advertisement per week above the average of six causes children to eat 350 extra calories per week – the equivalent of two packets of chips.
That would amount to 18,000 calories per year, which is estimated to correspond to around 70 Mars bars or 60 cheeseburgers. It could amount to an LBS 5 pound weight gain per year.
But the government disputed the claims because their own research found a general ban on all ads for junk food on TV – which Cancer Research insisted – would have no noticeable effect on children's health.
