I suggest exercise first. Even semi-regular exercise will help stimulate your appetite and need for sleep, making both of them harder to ignore or neglect. Then, of course, there are the benefits of exercise. I believe the means by which you choose to exercise is extremely important here. Based on my interpretation of your post, I'm going to divide exercise into the two categories. 1.'Exercise hacks': intermittent, low-impact physical activity that optimizes for your convenience and proximity, and done well goes almost undetected in your day-to-day. Usually, this type of exercise splits its time with another activity. Examples: use a treadmill desk while working; do five pushups every time you enter your kitchen; choose stairs over the elevator. I do not recommend this category for you. I believe you would be disappointed and unlikely to improve your overall health, and the things in between, by a meaningful and rewarding degree. 2. Activity performed as part of a group class that occurs during discrete, recurring periods of time. Exercise, a safe space for person-to-person interaction, accountability, and opportunities to laugh at yourself are all pleasant byproducts. Examples: beginner salsa or swing dancing; rock-climbing; parkour; whatever. I think you'll find this form of activity to be a lovely surprise and very rewarding. I urge you to give it a try.
