So true. The negative impact is vital especially since we are prone to creating ''comfort zones'' in our lives. For many years my schedule was University - Home - University -Home and nothing else. In this environment my obesity wasn't causing me any problems, especially in the safety of my own house where I would usually escape into the online world. It wasn't until I started exposing myself into other environments and social situations that I realised how ''handicapped'' I had become. This is why diets offer nothing. A total change in habits and behaviours is vital to break apart your comfort zones and force you to adapt into your new environment.
