Sorry, there are some of us, me being one of them who have done and do all that daily to NO avail! I was a single parent working 64 hours a week, cutting my grass, cleaning house, eating a vegetarian diet drinking loads of water and still had severe constipation and still do 30 years later. Hypo thyroid but managed and Hx of endometriosis which left scar tissue on my colon, so little to no movement. Had surgery:lysis of adhesions but to dangerous to remove to much every thing stuck together.Don’t want a colectomy then have to poop all the time, that is worse! Little to no movement there. I hate when you generalize. That is 5 things for people who are lazy, dehydrated, pop opioids and eat poorly. Also, may be people with an injury or handicapped and can’t move( not their fault). That’s just like saying to a type 1 diabetic your blood sugar would be controlled strictly with diet.
