Quite often it's really a question of gut flora and lack of knowledge regarding good eating habits.

Also fat cells are endocrinologically active, so they try to compel the person to, well, get fatter.

I've been doing this the hard way lately and there's still much that I don't know, because food and lifestyles used to be different, so my parents only told me what they knew from theirs.

To illustrate just how different, my great-grandmother reportedly disliked food that she described as "rich" - too calorie dense for her taste. By this definition cottage cheese was "rich".

The gut is an interesting component we are learning more about, for sure. But as an addict, it still comes down to changing your habits, which indeed fixes the floura.

I’m not sure I can really believe the often cited claim that a major component here is a lack a knowledge. Does anyone truly believe Cheetos are as good or better for you than broccoli?

The most obvious explanation to me is that we are just flooded with addictive food and bombarded with ads to entice us. That and healthy food presents more friction in terms of having to buy the ingredients and prepaid it, and we are all short on time and overstressed.
