This is pure speculation. The diet does seem to be one way to achieve weight loss but there is NO data on its effect on cancer incidence
Contrary to the usual assertions, some big studies show that fat women get LESS breast cancer. See the links in the sidebar here
Women can lower their risk of breast cancer by 40 per cent by following a two-day ‘life saver diet’ it has been claimed. Two-day diet could reduce breast cancer risk
Researchers at the University Hospital in South Manchester are claiming that observing a strict two-day diet, rather than trying to constantly cut calories, is a more effective way to loose weight.
The study, lead by Dr Michelle Harvie, and presented at the San Antonio Breast Cancer Symposium, found that women who followed a diet for just two days of the week lost more weight than those practising a full-time diet.
The researchers put 100 overweight female volunteers on one of three diets. The first diet consisted of consuming just 650 calories a day for several days of the week, with carbohydrates such as potatoes and bread cut out. For the remaining five days of the week the participants, whilst encouraged to eat healthily, could consumer whatever they liked.
Although volunteers on the second diet were also banned from eating carbohydrates for two days in a week, they were not set a specific calorie limit.
They were also allowed to eat as much as they wanted for the remainder of the week. The third and final group followed a more conventional diet, which included avoiding high-fat foods, alcohol and sticking to approximately 1,500 calories every day.
The results of the study showed that after three months the women on the two day diets had lost an average of nine pounds, compared to five pounds of those on the full-time diet.
Volunteers who had followed the two day diet had lost nearly twice the amount of weight of those on the more traditional full-time diet, and recorded significant improvements in three key areas linked to breast cancer. Their levels of hormone leptin dropped by 40 per cent.
Research professor Gillian Haddock, who also took part in the study herself, has said she would recommend the diet to friends and that she found it an easier diet option.
Mrs Haddock said: "I used to follow the 650-calorie diet on a Monday and Tuesday and it was great because I knew that by Wednesday I would be eating normally.
"It really suited me, I did it on my busiest work days and I would mainly have the milky drinks while I was at work so I didn't have to worry about shopping or taking in a specially prepared packed lunch."
The research, conducted at the Genesis Breast Cancer Prevention Centre at UHSM, was published in the International Journal of Obesity.
Pamela Goldberg, chief executive of the Breast Cancer Campaign said: "There are many breast cancer risk factors that can't be controlled, such as age, gender and family history - but staying at a healthy weight is one positive step that can be taken.
"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."
The scent of a man? It could be an STD, say scientists
Women wondering whether or not to take the next step with a new man in their life should heed the advice of Russian scientists - and take a deep whiff.
Sniffing a potential partner’s scent could tell if Mr Right has a sexually transmitted disease, according to a new study.
The research found that gonorrhea-infected men smelt 'putrid' to women, reports MSNBC.com.
'Our research revealed that infection disease reduces odor attractiveness in humans' wrote Mikhail Moshkin, a professor at the Institute of Cytology and Genetics in Russia, and the lead author of research published in the Journal of Sexual Medicine.
The off-putting scent may be subtle, more a chemical warning than a stench of body odor, but it does have some effect, according to the experiment conducted by Moshkin and his colleagues.
The researchers had already observed that certain animals, such as mice and rats, were not as attracted to the scents of those that were infected with disease, reports MSNBC.com.
They investigated if humans would also be turned off by the scent of an infected person, particularly one with an STD.
The researchers took samples of armpit sweat and spit from 34 Russian men aged between 17 and 25. The group included 13 young men with gonorrhea, 16 who were healthy and five who had had the disease but were successfully treated.
Then 18 female students aged 17 to 20 were asked to sniff the samples.
They obtained sweat samples by dressing the men in tight-fitting T-shirts with cotton pads sewn into the armpits. After an hour of sweating, men bagged their shirts and the pads were placed in glass vials for the women to sniff.
The women ranked the infected men less than half as high as healthy or recovered guys on a 'pleasantness score' that assessed scent. And when they were asked to describe the scent, the women said that nearly 50 percent of the infected men’s sweat smelt 'putrid'.
The researchers said the study indicates that humans, like other animals, might use scent to sniff out appropriate mates.
'We can conclude that unpleasant body odor of infected persons can reduce the probability of a dangerous partnership,' the scientists say in the MSNBC.com report.
