Energy balance

Higher levels of physical activity at the time of registry entry are associated with greater magnitude of weight loss maintained, although activity level does not predict the duration of maintenance.

While you don't need to exercise excessively to maintain weight, engaging in higher levels of activity (e.g., >3,500 kcal/week) is associated with having lost more weight initially. However, this does not mean you must keep exercising at that high level to *keep* the weight off; duration of maintenance was not linked to activity level.

GoodSupportsHIGH confidence
Activity level on registry entry is related to the magnitude but not the duration of weight loss... Those subjects reporting very high levels of activity (3,500 + kcal/week) were maintaining on average a 4.2 kg greater weight loss than those reporting low levels of activity (<1,000 kcal/week) after adjustment for age and gender.
