I am with BobL on this subject.
Stop for a minute and think back to hunter/gatherer times, and seasonality of eating patterns, different climates, different food sources. These people didn’t have cauliflower or brussels sprouts year-round, or fruits and grains.
They did eat “nose to tail”, and managed to get most nutrients from the animals they hunted. So much of what we have been taught is theory and marketing, unsupported by clinical evidence
Actually the lack is what really dictated the hunter gather’s life. And is dictating ours. They would go days, even weeks, without “proper” meals. So their bodies needed to build fat, to get through. So their bodies developed a fondness for food that built fat: carbs and fat. That’s why we still consider those to be primary sources of flavor in food, because our body WANTS them, so it makes them taste “good”, and rewards us with happy hormones when we eat them. Because our body isn’t currently wired up for being able to eat until stuffed multiple times a day. It doesn’t get it. It sees a big meal and thinks “oh it’s gonna be weeks until we’ve got this much food available again, CONSUME, add 30 pounds of fat to get us through”. We just need to get on top of the cycle.
