Usually eat a light diet, try to eat as little fried food, carbonated drinks, cream and chocolate as possible, eat as little as possible at night (it is best to change to fruits and vegetables), and then exercise properly in the morning and evening to lose weight.
As for what sports to choose, I suggest choosing my favorite. What is recommended in books or on the Internet is someone else's. Only by choosing the exercise that suits you and you like will you stick to it and lose weight happily and slimmer.
