RESUMEN
ABSTRACT: Social media could be considered as an interesting complementary tool to the public health domain. Although the literature has studied in detail the efficacy of some of these platforms, it is unclear whether Instagram® can play a role in the adoption of long-term healthy habits. A healthy food Instagram account called the "ChefTaste" was created to assess both the impact of this platform and the time needed for it to exert influence on its followers. After six months, a cross-sectional study was conducted. Out of 493 candidates, 171 did not follow any healthy food account, 204 followed "ChefTaste" account and 118 fol-lowed other healthy food accounts. Users who followed any healthy food account had a higher probability of not just eating better [OR=1.50 (1.03,2.18) p=0.036] but also indulging in more exercise [OR=1.46 (1.00,2.13) p=0.048] and were more cautious about what they were eating [OR=1.67 (1.13, 2.46) p=0.01]. Furthermore, on comparing the results of "ChefTaste" followers with those of other healthy accounts, we found there were no statistically significant differences with respect to healthy eating and weekly exercise. These findings demonstrate the effectiveness of Instagram® which could be explained by its social support and simplicity. Authors, therefore, believe that Instagram® could play a potential tool in improving the lifestyle of individuals.
