I wish I hadn't stopped exercising when I re-injured my shoulder. I wish I had just pushed through the pain, & kept up my routine, even if I had to down-play it a bit; still would have been better than stopping all together.
But wishing does nothing for me NOW. It's the NOW that I am concerned with the most. Even when hitting a stubborn plateau... it's better than gaining more weight....or worse - giving up altogether (which I admit I am dangerously close to doing! & THAT'S why I come here! So I won't DO that!!!!)
What really irks me is when someone who is much more overweight than me tells me that I
"don't need" to lose weight. HA! - Who are they trying to fool? Just because I'm not 200 or 250 doesn't mean I'm at a healthy weight by any means. 160 pounds on my 5'3'' frame is ENTIRELY too much weight. FOR ME.
I try to be supportive no matter what someone's goal is, unless it's completely unhealthy - then I'd just say
"That's completely unhealthy... but it's YOUR body, so do what you want with it."
