Slipping Into A Food Coma? Blame Your Gut Microbes

November 27, 2015 3 min read

When you sit around the holiday table, looking at the damage done, swearing that you cannot handle even one more bite, it may be your microbes talking. Researchers have found clues that suggest when certain bacteria in your gut have had enough to eat, they single to the brain that it is time to stop. 20 minutes after eating, E. coli bacteria -- common in the human gut, produce proteins that have been tied to the hormone responsible for appetite suppression. This study is one of the first ever to examine microbial activity in the body and human behaviours. The human body contains trillions of microbes, the majority of which are found in the gut. In fact, 70% of all the microbes in the body are found in the colon. One of these microbes is E. coli and this new study suggests it may play a role in shaping our eating habits. Save-time-and-money-on-Thanksgiving-dinner [bctt tweet="Slipping Into A Food Coma? Blame Your Gut Microbes"] Whatever food you put into your body, be it a holiday meal or a light snack, contains nutrients that are also absorbed by microbes, prompting their reproduction. The scientists have come to suspect that it is beneficial to this gut bacteria to signal the host to regulate food intake in order to help control their population. It was this suspicion that lead the researchers to look for changes in E. coli relative to feeding. Sergueï O. Fetissov, of Rouen University in France and co-author of the new study said that he and his colleagues had previously studied a bacterial protein called ClpB. Because it was easily traceable in the blood and gut, they were able to measure how much of it the E. coliI produced both before and after it fed. What they noticed was that about 20 minutes after feeding,  E. coli bacteria produced twice as much of the ClpB protein as they did before they fed. This is interesting when you consider that it is usually 20 minutes after eating that people begin to feel full.

When injected into mice and rats, they found that this particular combination of proteins reduced food intake. By looking more closely, they found that these proteins stimulated the release of the hormone peptide YY, or PYY. "PYY is one of the main hormones released from the gut after a meal, so it signals satiety to the brain," Fetissov explained. "It starts to be released about 20 minutes after the meal. So, if you look at the dynamic of the bacterial growth, they fit perfectly with the dynamic of PYY release in the blood after the meal." But, it is worth noting that E. coli makes up a very, very small part of your gut bacteria, making up only 1% of the population in the colon. Fetissov is excited by the information that can be gained by studying other gut bacteria. He believes that we will likely find that bacteria plays a huge role in the controlling of molecular pathways that influence other behaviours and emotions. "We will continue to look into the mechanism of how that bacteria can regulate appetite, particularly in people who are obese or who suffer from binge-eating disorders," Fetissov said. "And if we find some involvement, I hope we can also treat these conditions." Interesting research to say the least! Are you relieved to hear that your holiday overeating may have nothing at all to do with willpower? Source: Huffington Post

Shipping & Delivery

Due to COVID-19, shipping systems the world over are experiencing abnormal delays. There is an enormous demand on postal and delivery services as online shopping has skyrocketed, due to store closures and stay-at-home mandates. This is an unprecedented situation, and we are working around the clock to fulfill your orders as quickly as possible. To be clear, we are filling orders in 4-6 days, and we are shipping immediately after that. Once shipped, our shipping partner, UPS, will get your order out to you as quickly as possible. Thanks for your support and understanding.

Are you in Canada? Specifically, are you outside of a metropolitan centre? We need to alert you to a disruption in shipping due to COVID-19. Our preferred shipping provider, UPS, has informed us that they cannot guarantee express shipping for many locations. We have also seen that packages delivered to Toronto, Ottawa, Vancouver, etc, are not waylaid, but packages delivered to areas just outside of these cities are being held in transit for days or even weeks. UPS has discontinued their guarantee of 1-4 day delivery, which you can read more about here. Therefore, we can guarantee early fulfillment but not early delivery of our goods from our warehouse to your door at this time.

We want you to start your fitness journey with us as quickly as possible, that’s why we send every package to the USA & Canada via expedited or standard shipping (whichever is faster) with our partners at UPS. Once your order has been processed successfully we try to have your shipment prepared within 4-6 business days, and it typically takes 2-4 days to get to you once it leaves our warehouse.

We currently DO NOT SHIP to locations outside of the US and Canada. We DO NOT ship to a P.O. Box number.

We ship all of our physical products with UPS, from our warehouse location in Kingston, Ontario, Canada. Sometimes delivery can be delayed by circumstances out of our control, like postal & custom delays, back-ordered products or incorrectly entered shipping addresses. If there is a delay at Customs, a representative of UPS may contact you to provide your identification in order to receive your package. Please do this ASAP: Customers will be responsible for any additional shipping fees for failure to provide the required information to release a shipment.

Make sure when checking out and paying for your order that all of your information entered is correct! If you notice a mistake in your address, please try to contact us before your order is processed for shipping to avoid any missed shipments or delays. As soon as we process your order for shipping, you will receive a shipping confirmation email that contains your UPS tracking number. You can head on over to the UPS Website to see where your products are. Note: tracking information may take 1-2 business days to be updated in the UPS system

If you are not home when your package is delivered, BodyRock is NOT responsible if it is stolen. Please contact us if this happens to you and we will provide you with all the information needed to take the next steps.
