In general:
Eat a varied diet, leaning towards plant-based foods. Whole grains if you can. Don't unreasonably cut out whole categories of food. Being vegan is HARD, vegetarian (or mostly so), not so much. Watch the sugar, including the fake type. Eat your calories instead of drink them.
Also, get some activity. Walking for 15 minutes daily is better than nothing, but try to get more than that most days. IF you can have fun doing it, great! If you lack motivation, do something on the easy side as it is easier to talk yourself into. It is better to this half-assed than not at all, after all, because it still counts.
Keep an eye on stress as much as possible. If you smoke, try quitting (I suggest a vape or e-cig). Drink in moderation, but do have some coffee.
Once you get these general things done, you are well on your way.
