A little inspiration for everyone... The photo below is me in the same shirt. On the left, 9/1/2018 and about 350lbs. On the right, tonight after my workout and right on 250lbs.

I turned 40 just before Halloween and have been very overweight my entire life (and, let's be honest, I still am). But it can be done at any age. Just find something you can stick with, no matter how small it seems, and then stick with it. Be patient. Over the course of 3 to 12 months, the tiny changes you can't see from one day to the next will add up to a dramatic transformation.
There will be ups and downs. Pay attention to the day-to-day, but don't get hung up on it. Binging, skipping a workout, etc is like throwing an INT or giving up a homerun. Acknowledge it, figure out why it happened, and move on.
