Two-Day Dieting a Week Reduces Breast Cancer Risk by 40%

A new study has revealed that sticking to meager diet for two days a week could reduce the threat of getting affected with breast cancer by almost half.

The findings of the research appeared in the International Journal of Obesity. It is a Wythenshawe Hospital study, which was led by Dr. Michelle Harvie.

The research was conducted on 100 overweight women aged 30 to 45 from Greater Manchester having the genetic risk of developing breast cancer. They were divided into two groups with equal members. One was put on 650-calorie-a-day diet for two days a week that included green tea, Bovril, of semi-skimmed milk etc., while the other group took a 1,500-calorie-a-day diet for the whole of the week, but they were asked to avoid fatty foods.

They were followed for a period of six months. After that, it was discovered that the women of the first group had lower levels of leptin and insulin in their blood that led to breast cancer. The concentration of leptin dropped by an average of 40% while that of insulin fell down by an average of 25%. Also, women who shunned an average of a stone in weight saw their breast cancer causing C-reactor protein fall by 15%.

In the other group, the cancer-causing hormones in women recorded to be lower after six months, but the decline in the level of insulin was comparatively less than in the women in group one.

"This intermittent dieting approach provides an alternative to conventional dieting which could help with weight loss, but also potentially reduce the risk of developing breast cancer", said Pamela Goldberg, Chief Executive of the Breast Cancer Campaign.
