It is now accepted that exercise is equally important as the meds. I agree that our ability level will be different BUT we can all do some. You just need to find out what you can do and build on it. I use YouTube. There are all sorts of exercises - some specific for PD, others for building upper and/or lower body strength, or those focusing on you abs and glutes (if like me you have osteoarthritis). There is one that helps keep your fingers supple and is specifically for PD. If you can swim that would be fantastic. (I can’t any more - I just go in circles as my left is weak!). As for diet, there are opinions abou the Keto diet. I don’t follow any regime as I have various reaction to particular foods. I use Almond milk for instance as cow’s milk gives me catarrh. I have also reduced intake of meat and usually try and have fish or all vegetarian. I drink prune juice and eat the fruit as well. I eat healthily with lots of fibre and fruit. I keep a vigilant eye on my BMI and weight. Should take Statin but don’t like the idea of injesting more drugs
