Weight loss amount ‘more important than diet in tackling obesity-cancer link’

29th March 2016

Losing a greater quantity of weight is a more important consideration than selecting a specific diet type when trying to reduce the prevalence of obesity-related cancer cases.

This is according to a new study from the University of North Carolina Health Care System, which examined whether weight loss via four different diets was linked to reduced tumour growth in laboratory models of breast cancer.

It was shown that tumour sizes did not differ between obese mice, with animals returning to a normal weight on a low-fat diet. Those specimens that lost significant amounts of weight on three calorie-restricted diets had smaller tumours.

As such, it was concluded that the degree of calorie restriction matters more than the specific dietary changes used to generate the weight loss when seeking to address this problem.

Dr Laura Bowers, a postdoctoral fellow in the University of North Carolina Lineberger Cancer Control Education Program, said: "The overall message is that the breast cancer-promoting effects of chronic obesity may not be easily reversible with moderate weight loss, but more severe weight loss diets may be effective regardless of whether carbohydrate or fat is restricted."

However, she added that the findings remain too preliminary to make any kind of recommendation for human health at this stage.ADNFCR-8000103-ID-801815497-ADNFCR
