Adherence
Individuals with unhealthy pre-pandemic lifestyle patterns (low diet quality, low physical activity) are more likely to improve their diet quality and lose weight during periods of high lifestyle disruption compared to those with healthy pre-pandemic patterns.
If you currently have unhealthy habits, a major life disruption (like a pandemic or job loss) might actually be the catalyst you need to improve your diet and lose weight, simply because you have more room to improve than someone who was already healthy. Focus on small, sustainable changes to diet quality and physical activity, as these are the key drivers of weight change during disruption.
Individuals most adherent to unhealthy pre-pandemic health behaviours improved their diet quality (0.93units) and weight (-0.79kg) compared with those reporting healthy pre-pandemic behaviours (0.08units and -0.04kg respectively), irrespective of relative deprivation.
Why this rating
Large prospective observational study (n=1.1 million) with independent replication cohorts, though self-reported data introduces recall bias.
