To analyze lifestyle habits and weight evolution during the COVID-19 pandemic-associated lockdown, in diabetes and overweight/obesity patients (body mass index (BMI) [25–29.9] and ≥30 kg/m2, respectively). We collected information on participants’ characteristics and behavior regarding lifestyle before and during the lockdown, through the CoviDIAB web application, which is available freely for people with diabetes in France. We stratified the cohort according to BMI (≥25 kg/m2vs < 25 kg/m2) and examined the determinants of weight loss (WL), WL > 1 kg vs no-WL) in participants with a BMI ≥25 kg/m2, in both univariate and multivariate analyses. Of the 5280 participants (mean age, 52.5 years; men, 49%; diabetes, 100% by design), 69.5% were overweight or obese (mean BMI, 28.6 kg/m2 (6.1)). During the lockdown, patients often quit or decreased smoking; overweight/obese participants increased alcohol consumption less frequently as compared with normal BMI patients. In addition, overweight/obese patients were more likely to improve other healthy behaviors on a larger scale than patients with normal BMI: increased intake of fruits and vegetables, reduction of snacks intake, and reduction of total dietary intake. WL was observed in 18.9% of people with a BMI ≥25 kg/m2, whereas 28.6% of them gained weight. Lifestyle favorable changes characterized patients with WL. A significant proportion of overweight/obese patients with diabetes seized the opportunity of lockdown to improve their lifestyle and to lose weight. Identifying those people may help clinicians to personalize practical advice in the case of a recurrent lockdown. •The lockdown was associated with an opportunity to change weight/lifestyle in patients with diabetes and overweight/obesity.•Weight gain was observed in 29% of overweight/obese patients with type 2 diabetes.•19% of overweight/obese patients with type 2 diabetes took advantage of the lockdown to lose weight.•Smoking cessation was more prevalent in patients who lost weight as compared to patients with weight gain or stable weight.
