Everyone "ought to:"
- Avoid grains
- Avoid refined seed oils
- Avoid improperly prepared beans
- Get plenty of fresh air and sunshine
- Get plenty of sleep
- Walk several miles a day
- Avoid cigarette smoke
- Squat, deadlift and benchpress (I guess exceptions to this rule are para/quadriplegics and people missing arms and legs?
Will everyone do that? No. But I don't understand how anyone can disagree with any of that. You may not want to be a body builder. You may not want to have single digit body fat. But you should still walk and lift heavy weights. Regardless of aesthetic goals, they are good for 100% of us.
