Seconding what others said about habits and building a routine. From the power of habit book, I picked up that it's easiest to break old and make new habits at times of life change - change in numbers of people around you (death, birth, divorce, coupling up), change of location or work. I made proximity to gym/swimming pool one of my most important factors in my last flat hunt, mapped out relevant facilities in London, wrote a scraper that searched for flats in walkable radius, used Google Maps API to calculate walking distance and uploaded it to google sheets for me to review. After moving to the new flat, I made sure to go to the gym every morning for the first 3 weeks. Even if I did little exercise (10 mins of cardio), it was about developing a habit of getting up and going there regularly. So far it's been good, though I wouldn't say the results are visible to everyone in the outside world, not that I care anyway. Being so close to the gym removes excuses like "it's not on the way to work", "I cannot carry my towel with me". Going in the morning makes me free to do anything at night without feeling bad about skipping exercise. I am lucky to have a fast rate of metabolism and most of my cooking repertoire is around salads and basic meals, which imho are healthy. I stock up and freeze meat that I buy from butchers and farmers' markets.
