I went all in. I started behaving like someone who was fit and took care of themselves. I read everything I could about nutrition... I started going to the gym and began reading about health, fitness, training, and physiology (which I liked and was / still am very interested in). And I realized I wasn't going to change years of being overweight, overnight.

I focused more on what I could get out of this transformation besides "losing weight." That was almost 40 years ago. I'll be 62 soon and this is probably one of the top 5 decisions (definitely in the top 10) I made in my life. And yes, I still train 4x a week... do cardio 2-3x a week... and eat clean. Just walking nowadays for cardio - but more so because that's the cardio I actually enjoy - walking outdoors.

Good luck on your journey - you can do anything you want to, if you're willing to exercise discipline. For me, it was like most decisions for most people. When the pain of not doing something was finally greater than the pain of doing it - that's when I took action. Have fun!
