I think the addition of 2 things in life can improve its health and fitness status. First of all, you need to go with a healthy and balanced diet. Instead of inorganic and junk food, it is better to go with green food, lean meat and fruits. The second thing that you consider is to start doing workout and walk. I know in the beginning, it sounds tough to do workouts, especially if you want muscles etc. I would suggest you take multivitamins and other energy supplements from here

Moreover, you should take a healthy breakfast because if you want to stay fit and healthy after the 40s, then a good breakfast is essential. You can also enhance the use of calcium and protein in your diet. Better to conduct medical checkups regularly. Hopefully, you will stay fit and healthy after your 40s, 50s, 60s and even 70s.
