Before we start talking about the evils of sugar, we are anxious to know how your first day went. How did everyone do? Was it an easy transition? Are there still a few kinks that need to be worked out? We will have a full check in on Friday, but would love to hear how the first day went.
For many of us, myself included, sugar proves to be the toughest part of clean eating for the long term. I have a sweet tooth that dates back as far as I can remember and to this day the smallest treat can send me on a night long sugar binge. I have tried several times to go cold turkey and cut the sugar out for good, but unless I am on a challenge and have some external motivation to cut it out I find it sneaking its way back in. This post is an attempt to look at what happens on the physiological level when we go on these sugar binges and hopefully provide some motivation to help avoid them in the future.
We all know that sugar filled treats are not good for us, but we partake anyway for a variety of reasons that we usually think are emotional. Birthdays, a special treat to celebrate something, or just to mark the end of a long week, but there is more to it than just an emotional connection.
Lets look at the whole process. Refined sugars are what we are looking at specifically. What happens when you eat that piece of cake, candy bar, pie, or drink that soda, juice, or sports drink?
Within minutes of consumption that sugar will be broken down to glucose and make it's way to your blood stream. High levels of glucose in the blood are toxic and the body treats this situation as an emergency. The pancreas will respond by pumping out a storage hormone called insulin to get that sugar out of the blood. Insulin will store glucose in the muscles and liver first, but each have a limited capacity for storage and anything else will be shoved into fat cells to be used up later.
That is what is happening inside, but what is going on outside? Many people will notice they are getting warmer, your heart can start to race, some may even sweat. Some have a sense of a "high" and some may not notice a thing(if this is the case it is a bad sign), but you can rest assured things are happening.
The rush of insulin is more than what you need to return the blood chemistry back to normal and insulin does its job very effectively. So now, about 45 minutes to an hour, after you eat that treat your blood sugars are now low. You are starting to feel tired and a bit cranky. The remaining insulin in your blood wants to do its job and store something, so a signal is sent to your brain that you are hungry and need to eat. This explains why you can and want to eat that last piece of cake, candy, cookies, pizza(carbs are sugar ya know) even though you are full and your stomach hurts.
Most of us, with the exception of Dawn(who has the will power of a Tibetan Monk) will give in to this craving and eat more crap and the cycle repeats itself. Now we are stuck on this blood sugar roller coaster ride with our energy swinging wildly and we use more "quick energy" foods. Remember the Snickers slogan "Hungry? Grab a Snickers." Some rely on an afternoon latte, or diet soda (if they are health conscious) to keep them going.
If this is an occasional thing your body is an incredible machine with the ability to adapt and return itself back to normal within a couple of days. If this is your daily practice the eventual consequences are much worse. Remember high and low levels of blood sugars signal an emergency in the body. Your body responds to an emergency the same way, whether you are being chased by a lion or your blood sugar is suddenly elevated from a high sugar meal, just in varying degrees. It releases hormones called cortisol and adrenaline, raises inflammation, and increases blood pressure.
Over time this constant low grade stress and inflammation can lead to any number of chronic conditions such as dysregulated adrenal function, chronic fatigue syndrome, fibromyalgia and thyroid dysregulation. The constant presence of insulin in the blood leads to insulin resistance and type 2 diabetes.
Is that piece of cake still looking so good? The scary thing is that I know this and I still eat it. That brings me to sugar as a drug. Consider this surprising fact.
Dr. David Reuben, author of Everything You Always Wanted to Know About Nutrition says, “…white refined sugar-is not a food. It is a pure chemical extracted from plant sources, purer in fact than cocaine, which it resembles in many ways. Its true name is sucrose and its chemical formula is C12H22O11.
It has 12 carbon atoms, 22 hydrogen atoms, 11 oxygen atoms, and absolutely nothing else to offer.” ...The chemical formula for cocaine is C17H21NO4. Sugar’s formula again is C12H22O11. For all practical purposes, the difference is that sugar is missing the “N”, or nitrogen atom. ...Refining means to make “pure” by a process of extraction or separation. Sugars are refined by taking a natural food, which contains a high percentage of sugar, and then removing all elements of that food until only the sugar remains. ...While sugar is commonly made from sugar cane or sugar beets.
Unbelievable! Sugar has been shown to have an effect on opoidoids and dopamine in the brain in the same way that drugs do leading to strong addictions.

Need any more convincing to curb that sweet tooth? Here is an awesome video that does a great job of explaining the process by which sugar does it's damage in the body. It is a summary of a video of a lecture by Dr. Robert Lustig called Sugar the Bitter Truth. That video is 90 minutes long and fairly technical, but if you are interested you can see it
here. This video is done by trainer and nutrition blogger Sean Croxton. His site is called
Underground Wellness and is worth spending some time on.
