From my experience: I didn&#x27;t have a sedentary life, well at least lets just say I wasn&#x27;t sitting at a computer all day. I was always out and about. My extra weight was from a mix of overconsumption and poor food choices.<p>I noticed there were unforseen changes in behaviour due to diet that I still find strange. Things like quitting pop. I used to grab McDonald&#x27;s food more often, but since quitting pop I avoid the place. Sometimes I still grab a burger from there, like 5 times or so over the last 14 years, but I&#x27;ll never get a pop and I don&#x27;t have a desire to go there and still avoid it with ease.<p>I still think diet changes are the single most important thing, but I just don&#x27;t think I could have gotten there without exercise.
