With increasing awareness about the ill effects of excessive weight, more women are now going on diets than ever before. Trouble is, that not all diet programs are healthy and some even damage overall health in the medium to long term, such as having an adverse impact on bone mass, etc.
However, new research conducted by the McMaster University in Hamilton, Ontario, now holds hope for premenopausal women who are overweight or obese and on diet programs, that they can achieve their weight goals while still remaining bone-healthy.
The results of the study were published in the medical journal The Endocrine Society's Journal of Clinical Endocrinology and Metabolism (JCEM). As per the report intake of all types of dairy products low in fat and including lean proteins lead to a marked improvement in the production of osteoblasts (cells that produce bone) and reductions in osteoclasts (cells that remove bone tissue). The study was conducted over a 16-week period looking into account diet- and exercise-induced weight loss. (1)
According to the author of the study, Stuart Phillips, PhD, “Our findings show that a diet with a high proportion of dairy foods and higher than recommended protein intake was associated with improved markers for bone health. Thus, to avoid deleterious consequences to their bone health, women who are attempting weight loss through dieting should practice consumption of more protein from dairy sources.” (2)
The study examined 90 overweight and obese premenopausal women over a 16-week period and varied their dairy food and protein intake keeping their level of daily exercise more or less constant. The exercises included aerobic training and resistance training, the intensity, duration and frequency of which were changed in a non-significant way.
The participants’ urine samples were taken. Blood samples were also taken to assess their serum levels.
