Brain Challenge managed to compete with Nintendo's own Brain Age in quality, and their language training games have been the only ones on DS that are worth a damn.
That's why when we see an announcement (or pseudo-announcement) of a new Coach game, we actually pay attention. This time, according to an OFLC rating, Ubisoft's going to help us lose a few pounds with My Health Coach: Weight Management. They're already taking a less direct approach to getting us to exercise with Quick Yoga Training, but we expect My Health Coach to have more of a nutritional focus. It could be an interesting product for blogger-shaped people who can get over the initial embarrassment of being told what to eat by a DS game.
