Just heard an interesting piece on the radio about a study showing that office workers have a fat effect upon each other.
If you work in an office with at least one obese person, your chances of gaining weight increase by double. Women are more susceptible to that weight gain than are men, the study showed.
A PLoS One study determined that "the number of desk-bound or light-activity jobs has increased in the
last 50 years from 50 percent to 80 percent, leading to a loss of 140 to
160 calories burned a day." That is one impediment. Another is lunch at the desk or lunch at the nearby deli. And still another is those damn constant celebrations for birthdays, anniversaries and the like that result in doughnuts and cakes.
Be aware and learn to say, "I have an allergy to sweets, sorry."
