According to new Harvard research [ Journal of the American Medical Association] involving 34000 women with a mean age of 54. Women need to exercise up to one hour pr. Day, in order to stop gaining weight.
The study had three groups of women.
– More than 7 hours a week
– Between two and a half to seven hours a week
– Less than 2 hours a week
Only the group with women doing 7 hours a week didn’t gain mean average weight over the research period of 13 years.
The study concludes; “Once overweight, it might be too late to because physical activity was not associated with less weight gain….
– A bit alarming really. But overall I read it as: Once you get overweight it just gets harder to keep a normal BMI.
Most sources still recommends at least 30 min exercise with elevated pulse.
