Whole Health Source Blog: Do Blood Sugar Levels Affect Hunger and Satiety?

From Dr. Guyenet:

“You’ve heard the story before: when you eat carbohydrate-rich foods that digest quickly, it sends your blood sugar and insulin levels soaring, then your blood sugar level comes crashing back down and you feel hungry and cranky.  You reach for more carbohydrate, perpetuating the cycle of crashes, overeating, and fat gain.

It sounds pretty reasonable– in fact, so reasonable that it’s commonly stated as fact in popular media and in casual conversation.  This idea is so deeply ingrained in the popular psyche that people often say “I have low blood sugar” instead of “I’m hungry” or “I’m tired”.  But this hypothesis has a big problem: despite extensive research, it hasn’t been clearly supported.  I’ve written about this issue before.

A new study offers a straightforward test of the hypothesis, and once again finds it lacking.”

The study at hand involved 15 healthy young men. Results may not apply to overweight post-menopausal women with T2 diabetes, but I bet they do.

    I have not heard this statement about eating carbs but I have heard it about desserts and sugar foods. Does it apply to candy bars, ice cream and cookies?

    You doubt it applies to “overweight post-menopausal women with T2 diabetes”? I’m sure you have a lot of women like this in your practice. I dare you to test it out using the Kraft Analysis–5 hour GTT with insulin assays. Include a questionnaire about fatigue, mood, hunger, cravings with check boxes for the patient to fill out every hour of the test. Then tell me a small study of 15 young men with healthy metabolism applies to overweight post-menopausal women with T2 diabetes.
