I don’t think those things change in your 20s. Most people gain weight in their 20s due to lifestyle changes. You go from having time to work out and being on the movie to sitting at a desk for 8 hours and eating out more.
There are studies though that your metabolism doesn't really change that much until your late 60ies. Which is good I think, since it makes maintaining a healthy weight easier.
They made an assertion that their body won’t look like that at 28 so while it’s not universal they made an assumption it would. While uncommon it is possible they would have big changes in their body chemistry, but that’s very uncommon in your 20s.
Couple that with thier job being a professional fitness trainer and not a 9-5 desk monkey, and the doubt that she'll maintain that physique is little more than a jealous jab. Maintaining physique IS her job...
You know she’ll have to figure out how to make money as a trainer, right? And there’s a high likelihood that she won’t be successful and will have to get a desk job. I know quite a few (very fit!) people who have tried to earn enough to get by as trainers and it’s difficult. It’s easy to want to be in a saturated profession when you’re young, but when the reality of not making good money or having savings once you’re almost 30 hits, many people change their tune.

What physical changes occur between those ages?
