Consuming fat and sugar changes the chemistry in your brain making you want more.

The name for this is hedonic hunger: craving food when it is unneeded. Scientists agree this may be the reason for soaring obesity rates in the U.S. and around the world.

The excess calories consumed are stored in fat cells. The problem is that your body’s preferred source of energy is sugar, not fat, so your body won’t really ever use these calories unless you’re fasting and in need of energy.

Extremely fat and sugary foods rewire the brain in the same way that gambling and cocaine do. Just seeing and thinking about these types of food trigger surges of dopamine (feelings of pleasure and reward) in the brain.

And, by eating more and more of these foods, the brain becomes desensitized and requires even more sugar and fat to obtain the same amount of dopamine release. This means that a person who readily eats fatty and sugary foods will need to consume more to feel the associated pleasure.

Many years ago we tried to avoid starvation; now, overeating and obesity are the killers. Perhaps it’s not the obese people themselves who are to blame,  but the cheap, high-calorie, omnipresent food.

What to do about it:

Stop bringing fatty and supersweet food products into the house and avoid going to venues that serve them (whenever possible).

Afterall, it’s called junk food for a reason.
