He could run outside around your neighbourhood or in a nearby park for an hour, make sure to eat less fatty and unhealthy food, eat more fruits and healthier meals. Also he could eat smaller portion sizes and drink plenty of water. If you can go to a nearby gym and do some exercises there
:)
Hope it works out for him
Chloe can determine if she was exposed to a communicable disease by knowing the portal
