eating the bare minimum amount of food needed to survive is not healthy at all that is an eating disorder. eat when you’re hungry until you feel full, go for a good mix of different types of foods and pay attention by how your diet effects things like your digestion, energy levels and how long you stay full for. when it comes to exercise it helps to find one or two active things you enjoy doing and do those as much as you can
you can and potentially should exercise more than just finding an active hobby you like if you want to be in really good shape but at a minimum you should walk to places as much as you reasonably can and try to find things you enjoy that keep you active to maintain a base level of health
