Weight reducing diets, mostly low in fat, may reduce risk of early death in adults with obesity, finds a study published in The BMJ. However, the researchers were unable to show if there was any effect of weight reducing diets on heart disease and cancer.

The research provides further evidence of the clinical benefits associated with weight reducing diets, which have already been shown to prevent of type 2 diabetes.

Adults with obesity have an increased risk of early death, heart disease, some cancers, type 2 diabetes and many other diseases.

Although not always adequately described, all but one of the trials included weight loss diets with sufficient information to establish that a reduction in fat intake was prescribed. Study design and quality of evidence were taken into account in the interpretation of findings.

The researchers identified high quality evidence from 34 trials that showed that weight reducing diets decrease all cause early death for adults with obesity – an 18% relative reduction in early death, corresponding to six fewer deaths per 1000 participants.
