Does The Sims count?
It's my favourite game series, though I haven't played the new one much due to annoyance at EA about the way they're handling the series.
In that, you prepare and eat meals from a selection, and you can raise your cooking skill to unlock a wider range of meals.
Controlling my Sim's diet is always something I find fun - selecting the meals. I like to create realism by aiming for a healthy diet and allowing occasional junk food.
Currently, if a Sim eats too much of any food, they get fatter. Boring as it probably sounds to most, I always thought I'd love for this to be more in-depth where choosing junk food regularly has a much bigger impact on a Sim's size and fitness, which could be improved with healthier food choices.
