The recommended half an hour of exercise a day may not be enough to stop weight gain. According to a US study of 34,000 women, an hour a day of moderate exercise is needed to fight the flab. Overweight women need to diet as well as exercise, a Harvard team reports in the Journal of the American Medical Association. The UK government advises adults to exercise for at least half an hour five or more days a week.
If this isn’t cause enough to change the way you eat and the things you consume, I don’t know what is. Obviously there’s something wrong with the way our food is produced/the things we put in it if the average woman has to exercise 7 days a week just to maintain weight.
