STUDY: Behavioral Changes Associated With Lower Obesity

HOW you eat, can determine how much you are hungry for. This, in turn can contribute to obesity.

That's the theory anyway. But how does it hold up if you were to actually test it? 

These scientists performed a systematic and exhaustive review with a "meta-analysis of epidemiological studies to provide a reliable close estimate of the association between eating rate and obesity."

In other words, this is a study of studies, to see if others have consistently found a link between eating pace and obesity. 

They included data from 23 published studies and found that (across all these populations) those who ate quickly were statistically more likely to be obese than those who ate more slowly.

How Does This Make Sense?
In over 15,000 subjects who have run through our eating behavior change program, we find that slower eating leads to substantially smaller portions at the plate (from one-half to one-third). This may be due to the delayed satiety signals that can help curtain hunger, and so calories, and so weight. 

How Does This NOT Make Sense? 
I love this study, but it's only a correlation. In other words, those who at faster tended to be heavier. While this makes sense, and there is a mechanism to explain why this would be true, there could also be something else that ALSO explains this relationship. 

For example, in the 1950s, someone found a correlation between coffee drinking and cancer. Those who drink coffee are more likely to get cancer. BUT, what were coffee drinkers in the 1950s also doing? Smoking. Once smoking was factored out, the cancer linkage went away.  

The Bottom Line for your Bottom Lines
This result makes perfect sense and certainly may be true. And even though this is a tentative result, it really costs you nothing to give this a shot for yourself to see if it has the same impact on your hunger, and so calories, and so weight. Good luck, you got this!
