Definitely a main reason for me, I'm very overweight, not 100% on exact weight as my scales max out, but larger than 22st at a small height. I had a very independent childhood, and never really learnt how to cook, what a healthy meal was, portion sizing, etc. I over ate unhealthy meals and continue to do so to this day, overeating too. I think it's became an addiction at this point and I can't really stop it. It also feeds into my financial situation another reason for my CTB due to getting takeout food a lot of the time.
I could fix this situation if I really tried, and I know I could. I started visiting the gym and doing calorie deficits early 2019 as a New Years resolution to try and sort my health out, and to be fair I lost 2st in the first 2 months, but I gave up shortly afterwards.
I just don't have the motivation to live in this life, so why bother with my health.
