I change it up every few weeks or so but I always include push ups, squats, and planks cus these are the goats for workouts (it also helps that I play basketball ever once and a while) then for cardio I either bike or swim and add on whatever guide I'm following. As for diet I don't eat red meat unless it's offered to me and I make sure to have a salad at least once a week I also find it helps to cut back on soda and ******* more fruit juice, vegetable shakes, and water.
