Gradually Change Your Eating Habits

I just wanted to check in for a couple of minutes and share a few thoughts I had regarding diet,weight loss and weight control.During a recent conversation with one of my sons regarding the issue of being overweight,which he is not, but his older brother is.I agreed with his observation that people don't change their eating habits as they get older or as they move into a more sedentary job or lifestyle."Back in the day" a lot of our predecessors,including women and children, expended most of their calories during the day with physical work. The heaviest meals of the day, on the farms anyway, were breakfast, and dinner,with supper being served in the evening and usually the lightest meal of the day.People rose early and went to bed early as well.
Basically we developed a love for all these traditional food from our mothers and grandmothers(comfort food)but we're on the whole not as physically active as they were, and we tend to skip breakfast altogether and eat the heaviest meal at a "fashionably late, European eight."
Maybe gradually, we could somehow retrain ourselves to getting the heavy eating over with by mid-afternoon and just have a light lunch in the evening, followed by a brisk walk.If we get everyone in tune with that maybe we could try cutting down on salt,sugar,saturated fats,white flour...................Every journey starts with the first step.Thoughts?
