Here's what I am doing as of right now for my health (in the eating and exercise department):
Stay hydrated: lots of water, green tea, herbal tea, and up to 3 cups of plain black coffee/day. No liquid calories except protein-rich smoothies.
Three meals and up to three snacks a day, portions just enough quantity to nourish.
Only 100 calories max allowed after dinner, and only if I am really hungry.
Dinner is the biggest meal most days and is made up of large servings of vegetables and a good portion of lean protein, along with moderate amounts of healthy fats (olive oil, coconut oil, olives, avocado).
I am using smoothies and shakes as meals or snacks on occasion to keep calories lower and protein higher; I have a couple of premade shake powders as well as my own concoctions made from Greek yogurt and fresh or frozen fruit and sometimes spinach.
I am keeping the grains low but occasionally having a bowl of oatmeal or some brown rice or that type of thing. I am not counting carbs right now but just not eating sugar or much grains.
I am keeping the protein higher and making sure I get enough healthy fat to feel satisfied.
Home gym is still in progress; paint chips are in hand and a shade of orange is being chosen while a few last items are sorted and stored to make more space in the room. I will use this gym on weekends and on days when I cannot get to the 'other' gym.
Tomorrow I start swimming at the 'other' gym. I am not sure how often I will do this. It depends on how my body feels. I am aiming for 3x/week but might go every weekday if it feels good! I will also ask for help to try the weight machines at the gym and do those 2 or 3 times a week.
That's the plan, and I am hoping this will make a big improvement in my health and ability to do more things without pain.
