There Is No Magic Diet: How Your Body Responds Depends On Metabolism

November 20, 2015 3 min read

Our bodies are pretty complicated machines and when it comes to losing weight, they can feel impossible to comprehend. For decades, we've been jumping into fad diets, failing and chalking it all up to a lack of willpower. But, science says that may not be the case. If you had a friend who lost weight on the Atkin's diet (or Dukan, or 5:2, or Paleo) you may have given it a shot thinking it would work for you too. But if it didn't, it isn't your fault. INPOST-diet Researchers have found that our bodies are completely unique in their responses to everyday foods. Even foods that are considered healthy, like tomatoes for example, can cause blood sugar levels to spike in some. The researchers also found that some people may be more sensitive to carbohydrates. Some people experienced a blood sugar spike while eating pizza and ice cream while others did not. The study monitored the diets of 800 people representative of the general Israeli population over the course of 46,898 meals. The subjects recorded everything they ate on a smartphone app and kept a close eye on their blood sugar levels with a portable monitor. The scientists also took note of the participants' sleep and exercise patterns. The data was then analyzed by a computer to determine the impact of individual foods on each participant. 46933943595222.CPi8JMXc2jitwSH7aVGY_height640 "Most dietary recommendations that one can think of are based on one of these grading systems; however, what people didn't highlight, or maybe they didn't fully appreciate, is that there are profound differences between individuals--in some cases, individuals have opposite responses to one another, and this is really a big hole in the literature," says Eran Segal, a computer scientist of the Weizmann Institute, Israel. Eran Elinav, a colleague of Segal, says, "Measuring such a large cohort without any prejudice really enlightened us on how inaccurate we all were about one of the most basic concepts of our existence, which is what we eat and how we integrate nutrition into our daily life. In contrast to our current practices, tailoring diets to the individual may allow us to utilise nutrition as means of controlling elevated blood sugar levels and its associated medical conditions." [bctt tweet="There Is No Magic Diet: How Your Body Responds Depends On Metabolism"] Overall, eating dietary fiber was found to help reduce blood sugar levels, while lack of sleep, high salt diets, and high cholesterol levels had a negative impact on blood sugar. The authors suggested that assigning foods a glycemic index was not actually useful since it could vary greatly person to person. INPOST-danidiet             So why do we have such a diverse reaction to foods? Gut bacteria. No two people have the same make up of gut bacteria. When people fail on diets, it is widely believed that it they just aren't listening to or following the 'rules' when really it might be something else. "Maybe people are actually compliant but in many cases we were giving them wrong advice," says Segal. "It's common knowledge among dietitians and doctors that their patients respond very differently to assigned diets. We can see in the data that the same general recommendations are not always helping people, and my biggest hope is that we can move this boat and steer it in a different direction." Does this information change the way you view dieting? Do you think you can find and follow what works for you without having to adopt a specific diet plan? Source: Daily Mail

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 with our partners at UPS. Once your order is received and processed, it typically takes 2-4 days to get to you once it leaves our warehouse. That’s our commitment and we stand by it.

We ship within Canada and the United States via UPS with Standard & Expedited shipping (whichever is faster)

For locations outside of the US and Canada, we ship using FedEx International (EUROPE and Other Nations), which is usually in transit for 7-10 business days, depending on location.

We ship all of our physical products with UPS, from our warehouse location in Kingston, Ontario, Canada. Delays caused due to custom withholds are not included in these estimated delivery times.

Returns & Exchanges

BodyRock Equipment

We offer a 30-day return policy, as long as: it is not more than 30 days past the date of delivery; and your item is in its original condition and packaging with the original order number. Refunds will be issued when the equipment is received back to the BodyRock warehouse, minus the original cost of shipping, and the customer is responsible for the costs of return shipping. To request a refund on physical product purchases, please contact us.

Digital Products

We cannot issue refunds on digital goods such as e-books or videos, as these are non-tangible goods that are irrevocable once the order is placed.
