    Factors Factors Contributing toContributing toGradual Weight GainGradual Weight Gain

    • Most individuals gradually gain weight over a long period of timetime– Often without realizing they have changed their behaviors

    • These changes could be very small– An excess of only 10 Kcal/d could result in a weight gain of ~1 lb/yr

    ~10 lbs in 10 years

    • The modern environment has taken successful body weight• The modern environment has taken successful body-weight control from an instinctual (unconscious) process to one that requires cognitive skill and effort and that individuals who are not devoting substantial conscious effort to managing body weight are probably gaining weight. (Obesity Reviews 2002;3, 69–74.)
