Mature woman here! Results are slow, in my case, but I have come to accept that slow nature of weight loss. That's been difficult, but I have to ask myself - when I hear that I lost x pounds at the scale, and it seemed to take such a long, long time - would I want those x pounds back on my body? Nope.
Not regaining weight is the challenge, IMO. I've lost thousands of pounds in my lifetime so far. I can lose it, sure - but then, I gain it back!
