The causes of obesity in Americans

Americans are generally larger than other people around the world due to numerous causes of obesity. One major factor is diet, as many people in America have access to unhealthy foods that are high in sugar, fat, and empty calories (Hernandez et al., 2017). This has been heavily influenced by marketing tactics used within the food industry which entice consumers into buying items laden with additives as well as processed goods instead of healthier options like fresh fruits and vegetables (Brownell & Warner 2009). Another cause can be attributed to lifestyles choices such as lack of physical activity; this could include sitting for long periods of time at a desk job or within cars commuting from place to place without any exercise being involved (Caspersen et al., 1985). Additionally genetics can be partly responsible for why some individuals gain weight more easily than others due their family history or metabolism rates which may make it difficult for them stay trim even when following regular healthy routines (Pérusse 2011). Finally environmental factors play a role since there may not always be safe places designated for outdoor recreation available everyone living in certain parts of cities versus others making it less likely individuals will get outside let alone engage activities that involve physical exertion while doing so (Bentley et al., 2005). All these things demonstrate how complex issue obesity has become over time making it necessary address multiple elements simultaneously order successfully combat its prevalence amongst American citizens moving forward.
