I think this article is relevant to all of us who struggle with weight, irrespective of type of surgery or diets etc. so thought I'd share. What Happens to Your Brain When You Eat Junk food (And Why We Crave It)

Proteins, fats, and carbohydrates that it contains. In the case of junk food, food manufacturers are looking for a perfect combination of salt, sugar, and fat that excites your brain and gets you coming back for more.

Here's how they do it...

How Science Creates Cravings

There are a range of factors that scientists and food manufacturers use to make food more addictive.

Dynamic contrast. Dynamic contrast refers to a combination of different sensations in the same food. In the words of Witherly, foods with dynamic contrast have:

... an edible shell that goes crunch followed by something soft or creamy and full of taste-active compounds. This rule applies to a variety of our favorite food structures -- the caramelized top of a creme brulee, a slice of pizza, or an Oreo cookie -- the brain finds crunching through something like this very novel and thrilling.

Salivary response. Salivation is part of the experience of eating food, and the more that a food causes you to salivate, the more it will swim throughout your mouth and cover your taste buds. For example, emulsified foods like butter, chocolate, Salad Dressing, ice cream, and Mayonnaise promote a salivary response that helps to lather your taste buds with goodness. This is one reason why many people enjoy foods that have sauces or glazes on them. The result is that foods that promote salivation do a happy little tap dance on your brain and taste better than ones that don't.

Rapid food meltdown and vanishing caloric density. Foods that rapidly vanish or "melt in your mouth" signal to your brain that you're not eating as much as you actually are. In other words, these foods literally tell your brain that you're not full, even though you're eating a lot of calories.

The result: You tend to overeat.

In his best-selling book chips to taste. He zeroed right in on the Cheetos. "This," Witherly said, "is one of the most marvelously constructed foods on the planet, in terms of pure pleasure." He ticked off a dozen attributes of the Cheetos that make the brain say more. But the one he focused on most was the puff's uncanny ability to melt in the mouth. "It's called vanishing caloric density," Witherly said. "If something melts down quickly, your brain thinks that there's no calories in it ... you can just keep eating it forever."
