It's so easy to completely fail to realize that, most of the time, being overweight is completely your fault. People who have been overweight most of their lives and have eaten a certain way that entire time are at risk of having a complete lack of self-awareness regarding the issue. All it takes is a real effort to eat healthy and exercise, and it's amazing how quickly your mindset can change.
Being healthy is a choice. Not eating healthy or moving your body is a choice. Anything else is an excuse. No time after work? Hate cooking? It's too hard? Too busy in general? Hate working out? Too bad. Make time. Push through the gym. Work up to a good routine.
Precisely this.
Generally it's your life, you can do whatever you want. But don't expect cuddling or constant approval when it comes to making excuses. I assure you if people properly counted calories and cut them down hard while exercising on regular basis they would be shocked by results.
They don't want to though, effort is hard.
There are cases when it's actually medical condition due to body not functioning properly and then I do feel really bad because losing weight is a herculean task, but most of the cases it's just "large meat pizza and wings" for dinner every day.
I remember girl who was overweight and depressed, with her jolt to come to the gym being some kids calling her "hamplanet" at a shop. She pulled through in about 6 months and told me with tears in her eyes she likes to leave home now and in some twisted way is thankful to the kids (they were still little shits).
My best advice would be this, aside cutting soda from you life (shit is killer).
