Don’t judge I just want help please

Please don’t judge I have debated on posting but I think you can help cheer me up so I weigh 202 pounds and my height is 5”8. But my goal is to start the keto diet and am almost at a date that I want to start but is there any one who can send me there exercises because this summer I will not be able to go to a gym all I will be able to do is swim and chase kids so any recommendations
