Eat Slowly
Back at the beginning of the year, when I asked y’all what kind of helpful info you’d like to see on the blog, Lydia mentioned wanting to lead a healthier lifestyle. Well Lydia, I live to serve. So here’s the first installment of health-related blogs. I’m partial to things that people can incorporate into their everyday lives without having to go out of their way too much, so those are probably the types of things you’ll be seeing from me.
One of the things you can do to limit weight gain is to eat more slowly. There have been a number of studies that support this idea – that simply eating slowly will reduce caloric intake, thereby improving a variety of health outcomes, such as lowering the risk of high blood pressure. Whether this is a direct cause and effect relationship is yet to be seen, but there does seem to be a significant correlation between the rate of eating and the risk of obesity.
How fast is too fast? Previously, it was thought that it took about 20 minutes for the brain to release the “fullness” signal, but a recent study on humans showed that it took about 10 minutes. What does this mean? It means that it takes time for your brain to detect the changes that result from eating. You need to give your body time to process these changes. If you eat too fast, then you will very likely overshoot the “fullness” mark, and before you realize it, you will have eaten more than you needed to. So scarfing down your lunch in 15-20 minutes is probably too fast. Chew your food slowly and savor it. Pause between bites. Relax and enjoy your meal.
Slow eating, by the way, is one of the hypotheses researchers have been studying to explain the “French paradox” – the fact that the French eat a high-fat diet, yet have a relatively low incidence of heart disease. It turns out that the French eat more slowly than Americans do, and also eat smaller portions. Do the French eat smaller portions because they eat more slowly? Perhaps, if they’re giving themselves time for the fullness signal to kick in.
For any of you biology/medicine/health nerds, here are the sources I used for this post, in case you’re interested in reading further. And also to prove to you that I’m not making this up.

February 6, 2009I’ve worked really hard to overcome comfort eating. I’m interested in knowing what other people do to resist cravings during stressful times.
In addition to that, I’ve changed my daily housework routine to be able to fit in a workout every day.
I eat fruit and yoghurt as healthy snacks but, I guess there’re more healthy foods. Suggestions are welcome.
Thank you Kathy for starting a health-related blog.
