The new findings, presented at the American Heart Association conference in New Orleans, has concluded yo-yo dieting more than trebles the risk of sudden death, and slim people whose size goes up and down are in the most danger.
The scientists who carried out the research say gaining and losing weight could be even more risky than staying fat.
It sharply increases the chances of a cardiac arrest caused by abnormal electrical activity in the heart.
And it raises the risk of heart disease, where arteries get clogged with fatty deposits.
Specifically, the study found that post-menopausal women who yo-yo diet over a prolonged period of time are at an increased risk of sudden death caused by heart disease.
The study, led by researchers at Alpert Medical School, Brown University, observed 158,063 post-menopausal women for more than 11 years. The association appeared strongest in women with a normal BMI at the start of the study.
Dr Mike Knapton, Associate Medical Director at the British Heart Foundation, said: “Coronary heart disease remains the UK’s single biggest killer.
“We need to do more to ensure women – including those who have a normal BMI – are aware that adopting a healthy lifestyle, and maintaining it, over a long period of time is the best way to reduce their risk of a sudden, devastating heart attack.
“There’s no way to reverse the damage caused by heart disease so it’s vital we all take steps to reduce our risk as early as possible – a lifelong balanced diet, that is rich in fruit and vegetables, is an important way to look after our heart health.”

According to weight loss expert Sandra Roycroft-Davis, you can escape the yo-yo diet trap.
Sandra said: “The natural behaviour when we want to lose weight is to say, ‘right – I won’t eat chocolate and I won’t eat cake, biscuits or drink alcohol or fizzy drinks because i Know they’re bad. I’ll count calories and do some exercise’.
“The problem is deprivation doesn’t work. When you make a conscious effort not to eat your mind anybody conspire together to make the opposite happen. It dates back millions of years to the survival instinct which cavemen relied on.
“When you cut back on food, your mind decides you’re in a famine situation so it sends signals to the parts of your body that produce and sore fat, telling them to produce more.
“People needs a good relationship with food if they’re going to achieve sustainable weight loss. They need to lose any mental hang-ups and develop good eating habits before they can begin to achieve their goals.
Giving up dieting is like giving up an addiction.”
