Higher lifestyle disruption, measured by changes in diet quality, physical activity, sleep, snacking, and alcohol, is associated with greater bi-directional weight change (both loss and gain) compared to low disruption.
Major life changes tend to amplify your existing habits. If you are already active and eat well, disruption might not change much. If you are sedentary and eat poorly, disruption might lead to significant weight loss or gain. To manage weight during disruptions, focus on maintaining consistent physical activity and diet quality.
A loss in body weight (-0.45kg) was greater in highly disrupted individuals compared to those with low disruption (-0.03kg).
