Stephan Guyenet: Why Do We Overeat? A Neurobiological Perspective

Obesity researcher and neurobiologist Stephan Guyenet, author of the Whole Health Source blog, has an excellent video Why Do We Overeat? A Neurobiological Perspective which surveys some research on appetite and obesity.

We are not adapted to our current environment. We evolved in environments where calorie malnutrition was the biggest cause of death. So cheap, highly palatable, nutrient-dense food with wide variety and heavy marketing to trigger food circuits in our brains is causing us to chronically eat too much.

One way to adapt: keep food totally out of sight.

I know how difficult it is to resist food especially if you are surrounded with people who loves to eat too. But one thing that works with me also is to ask someone like my family and friends to help me achieve my weight by being my constant reminder that I have a goal and that is to control my food intake and to exercise regularly. It's difficult if you only do it on your own. As for me, I tend to overeat since no one is there to stop or encourage me. It's better if you have somebody to remind you from your bad eating habit. Because If we don't control our weight then most probably in the future we will suffer.

As a guy with difficulty staying at anywhere near optimum weight, this is true. Not just for the issue of sight, but for a more pathetic reason. A lot of time my laziness outweighs my hunger, so whatever's in the house is what goes down the hatch.

The one time I successfully lost weight in a big way, I was living alone. I reasoned that my real problem was portion control, that I was always taking just one too many fork fulls of whatever I was eating. So I designed a recipe for a nutritionally complete muffin, (Basically a corn bread loaded down with vegetables and cooked meat.) the calorie content of which I could calculate fairly closely, and maintain with some consistency. And then I allocated myself 7 of them a day. No more, no less.

Portion control is much easier when you're dealing in integers.

Very difficult to do, now that I'm married, and neither wife nor child would consent to eat the same thing day after day, week after week.

However, I'd point out there have been some indications that at least part of the epidemic of weight gain might be an actual epidemic. As in, a new variety of intestinal flora spreading through the population, or something of that nature.

Here's a different perspective. Stephan Guyenet is known as the world's worst obesity researcher and for cherry-picking to ideology rather than fact. He simply is wrong. Take from a guy (me) or a gal who has lost well over 130lbs and kept it off for over 3 years or in her case over 10 years.
