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.<p>I believe the means by which you choose to exercise is extremely important here. Based on my interpretation of your post, I&#x27;m going to divide exercise into the two categories.<p>1.&#x27;Exercise hacks&#x27;: 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.<p>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.<p>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.<p>I think you&#x27;ll find this form of activity to be a lovely surprise and very rewarding. I urge you to give it a try.
