Obese lower death rate by dieting
Research: Weight loss reduces risk
Dieting may help reduce early deaths among obese patients, a new study has found.
With or without exercise, weight-reducing diets, usually ones that are low in fat and saturated fat, can reduce the risk of premature death for obese people, the authors said.
Being obese, or having a body mass index score of 30 or over, is associated with premature death.
It can lead to a number of life-threatening complications including some cancers, coronary heart disease and type 2 diabetes.
A team of researchers at Aberdeen and Auckland universities set out to assess the effects of weight loss programmes on deaths from all causes as well as from heart disease and cancer.
Their study, published in the British Medical Journal (BMJ), examined 54 studies with data on 30,000 adults dating from 1966 to 2016 with a minimum follow-up time of one year.
They found that during the average follow-up period of two years, weight-loss diets were associated with an 18% relative reduction in premature death among obese people.
They said that this corresponds to six fewer deaths per 1,000 participants in the studies.
But they were unable to show if there was any effect of weight-reducing diets on deaths from heart disease and cancer, or whether the participants saw any protective effect from developing these conditions.
“Our data support public health measures to prevent weight gain and facilitate weight loss using these types of diet,” they concluded.
Meanwhile a group of nutrition scientists has said eating whole grains is associated with lower mortality rates and lower risk of type 2 diabetes and heart disease.
