Let's talk about the pros and cons of carboloding before a sporting event.

0:28.3

So a lot of athletes are doing this, especially for endurance type sports that involve over 90 minutes, and so they might carbolode one to four days before this event using all sorts of carbs like sugar, these gels that many times have multi dextrin and dextrin, which is a synthetic sugar cliff bars or I think they have like these cliff gel packs, energy bars.

0:53.3

The goal is to beef up the glycogen reserve in the muscle and the liver, now glycogen is stored glucose molecules, and so the way that it works is that the glycogen stored in your muscle actually provides the muscle with glucose and glycogen that is stored in the liver provides the blood with glucose as well as the brain.

1:16.3

There's a big difference between the capacity that you can store glucose in the liver versus the muscle in the liver, it's only like 100 grams and the muscle, it's 500 grams, and so the reason why people doing this is just to go longer without teeth, but if you look at the type of fuel that they're running on, which is glucose, because they're not fat adapted, there's a pretty big limited capacity, because when you're talking about glycogen stored sugar.

1:44.3

It's only like maybe 1700 calories of stored glucose, maybe up to 19, maybe 2000 calories at the very most of stored glucose, so that would provide energy roughly about 90 to 120 minutes at the most, whereas if you were fat adapted, it's virtually unlimited as far as the amount of calories that you can use as energy.

2:11.3

Even someone that is not overweight has about 100,000 calories of stored energy as their fat versus like 1700 calories, so there's a huge difference, and so more and more athletes are becoming fat adapted because they're finding it gives them the unfair advantage because their ability to tap into this reserve that they didn't have when they weren't fat adapted.

2:36.3

The disadvantage of carboloding is limited capacity. Number two, you eventually hit the wall, that's called bunk, where you run out of sugar, and now you're hypoglycemic, and so you feel weak, you feel exhausted mentally and physically, and this forces you to drink and eat sugar during the exercise, but I remember when I was in my 20s when I was doing a lot of sugar, and I was exercising, I would hit that wall.

3:05.3

Legs literally would not move, so I know what that feels like, so I would just have some more sugar and keep going.

3:11.3

All right, so number one, limited capacity to hit the wall, three, there's a lot of gas, bloating, abdominal pain, when you do this, carboloding, because you're having excessive amount of fermentation, and so they're just going to go to town, and you're going to start getting excess fermentation and gut.

3:31.3

This one is diarrhea, that's one of the side effects. Now, what is the problem with diarrhea? Well, it's a big problem because of dehydration, you're going to lose your fluids and electrolytes, including potassium, magnesium, calcium, as well as sodium.

3:49.3

It's very, very dangerous to do any type of sporting event after you had diarrhea, because these electrolytes feed your heart.

3:57.3

And so if you're going to do some type of endurance exercise with maybe subclinical amounts of key electrolytes, you're going to be at risk.

4:07.3

All right, number five, fluid retention, when you carbolode, you hold water. For every one molecule of glucose, you hold between three to four molecules of water.

4:21.3

So potentially, you're going to be holding onto about two and a half kilograms or five point five pounds of actual water on your body. All right, and then you have number six blood pressure.

4:33.3

So when you're doing carbs, you're retaining sodium and you're retaining fluid and your blood pressure potentially could go up. Now, that can also be because of another thing I'm going to talk about, when you consume that much refined carb as sugar, you're going to deplete potassium, magnesium,

4:50.3

and other electrolytes. So the imbalance of sodium retention versus potassium deficiency can definitely set you up for higher blood pressure. All right, number seven.

5:00.3

And this is one of the things that I want to mention as far as a plus point or a positive thing or a pro as far as elite athletes, elite athletes have three times the insulin sensitivity, then non athletes.

5:19.3

And I'm talking about elite athletes. Apparently, they don't seem to get the severity of insulin resistance. And so if you're going to consume all this sugar, right, you're going to raise insulin, one big danger of that is insulin resistance.

5:32.3

So apparently being a elite athlete counters this insulin resistance. So that would be one benefit. And so far, I'm only finding this one benefit.

5:42.3

So exercise does counter insulin resistance and insulin resistance is really part of a prediabetic condition in the study that I'm quoting really has only to do with elite athletes, not someone that is less than that or just exercising, maybe on a regular basis.

5:59.3

I'm talking about elite athletes. All right, number eight, inflammation and leaky gut. All that sugar is very oxidating. It can affect the eyes, the heart, the kidneys, the nerves, and it can keep your body in a state of inflammation.

6:17.3

One thing we don't want when we're competing is more joint inflammation or muscle inflammation. All right. And number nine, and this is something that's not very known.
