She has lost a LOT of weight, I've heard 100lbs, but she still has a lot to go. As soon as she stops working out, because of kids or whatever, the improvement will be eradicated.
Lets say the OP convinces her to go to the gym every day... If she's not doing that already (lack of interest/willpower), as soon as she gets busy she's gonna use that as an excuse to stop going and the weight will come back. That is why I have a zero-tolerance attitude to chubbiness and bad eating habits. Chubby or "thick" turns into fat a few years down the road, and bad eating habits and general laziness are is like ticking time-bombs.
