Depends what you mean by what you find stressful. I guess when first starting out it can be a faff working out the best things to eat etc, but after time that gets easier. Some times I find it a bit depressing if I have a lot of social things and I feel like I cant eat what I would previously, but then I remind myself thats not such a bad thing.
It also helps making things in advance to freeeze them, and getting lots of quick and easy things to make, so each meal doesnt feel like it takes forever to prepare and make.
