I just read a study published by the New England Journal of Medicine from June of this year concerning the changes in diet and lifestyle and long-term weight gain in women and men.
More than 120,000 healthy men and women were observed over the course of 20 years. Their change in weight was evaluated at 4 year intervals.
The results of the study showed that within each 4-year period, study participants gained an average of just over 3 pounds. (Ever notice how easily your weight can creep up over the years?) With a 3 pounds gain being the average – a 4 lb weight loss at one end of the spectrum and 12 lb weight gain at the other end.
