We have learned from our Weight Loss and Diabetes pages, that increased blood sugar and the subsequent elevated insulin levels that result, lead to weight gain, and worsening insulin resistance.  Therefore, a significant key to keeping diabetes and weight managed, is to prevent unnecessary elevation in blood glucose and insulin levels.  One practice that causes these increases is eating frequently.  We have often told to “eat several small meals per day” to “keep our metabolism going.”  This is extremely bad advice.  Not to mention that no studies prove this to be true.  For those with diabetes, it is also claimed that we need these frequent meals to “keep our blood sugar up.”  Well, that is exactly what it does…keeps blood sugar up.  But the question is, “do we want our blood sugar up?  No!  We want it normal and stable.

Our body has two “states” in regards to food intake: a “fed” state (when we have recently eaten), and a “fasted” state (when we have not eaten in some time, such as when sleeping).  When we spend too much time in the “fed” state, insulin levels stay elevated for too long. Spending more time in the “fasted” state can lead to reduced insulin levels, and, thereby promote weight loss and blood sugar control.

To achieve this, eat 2 or 3 meals per day, no closer than 4-5 hours apart to allow yourself to return to a “fasted” state between meals (in other words, eat at regular meal times, no snacks in between).  Avoid eating within 2 hours of bedtime to allow for a sufficient evening fast. (This is why breakfast has it’s name…the meal that “breaks our fast.”)  Those with a significant amount of weight to lose, or those with severe insulin resistance, may choose to spend even more time in the fasted state, by doing “intermittent fasting.”

There are many ways to do intermittent fasting.  Some choose to do this daily by doing all of their eating within a small window, say 6 or 8 hours, and then fasting for the remainder of the day.  Some choose to have fast days throughout the week, eating on their regular schedule 5 days per week, and limiting calories two days per week.  Still others choose to do longer fasts.   I do not personally recommend extended fasting because I think there is a big potential for people to attempt it without sufficient understanding or without appropriate professional care.  I would highly recommend that if you wish to do extended fasting, please seek the advice of a healthcare professional who is educated on how to monitor those on a therapeutic fast.  I would also not recommend fasting for those who have a history of eating disorders.
