Eating too much? You can blame your brain.


How brain signaling drives what you eat. (And what to do about it).

It’s no secret that obesity rates have been rising in the U.S. (and other industrialized nations) for the past 30 years. It’s also no secret that Americans eat more than they used to; by almost 425 calories per day since the early ’80s.

For decades, government officials, research scientists, and fitness pros blamed this on a lack of willpower — folks’ inability to “push away from the table”. Diet book authors, TV doctors, and other nutrition experts tell us we’re gaining because of gluten. Fats. Fructose. Or whatever the nemesis of the day is.

But all this finger-wagging never really explains why.

Why are we eating so much food?

And why is it so hard to stop?

The answer lies in our brains.

You eat what your brain tells you to eat.

Ever open up a bag of chips planning to have a small snack, only to find yourself peering into an empty bag, just a few moments later?

Your brain is to blame.

Our rational, conscious brain thinks it’s in charge. “I eat what I want, when I want it. And I stop when I want to”. But we have a lot less control than that. Behind our decision-making processes are physiological forces we’re never even aware of.

You see, deeper brain physiology drives what, when, and how much we eat — along with its co-pilots of hormones, fatty acids, amino acids, glucose, and body fat. For the most part, our conscious selves just come along for the ride.

In this article, we’ll explore:

  • how our brains dictate so many of our food choices;
  • how these physiological forces can lead to weight gain; and

what we can do to take the power back.
