 I don't understand insulin.

Not the supplemented variety but our own pncreas type. No matter how much I read about it I just can't understand it. It is secreted to lower blood glucose levels right? So why is the "dreaded" insulin spike from high GI foods detrimental? I don't understand the insulin spike and increased fat storage. Basicaly I don't understand insulin and its effects. How does the insulin spike produce negative effects? I understand proper diet very well and I follow mine very strictly. I am very good about my diet and quite knowledgeable about it. I avoid sugars and high GI foods but I don't know why and that bugs me. This is the grey area for me. Can some one help me out here?     | ||

I DON'T UNDERSTAND INSULIN THAT MUCH EITHER. BUT THIS IS WHAT I KNOW. IT IS THE MAIN HORMONE RESPONSIBLE FOR TRANSPORTING NUTRIENTS INTO YOUR BODY, AND IT SHOULD BE LIKE OVER THE COUNTER INSULIN. I GUESS THE MAIN REASON FOR THE INSULIN SPIKE THEORY IS THAT IT CONVERTS TO FAT. | ||

look i am not an MD and am not giving madical advice but this is the way i understand it. Insulin is nothing more than a carrier that enables the cells to absorb glucose. In other words it takes the glucose molecule and transports it into the cell for use. When blood sugar rises it means that an excess of glucose is in the blood that hasnt been transports into the cells, hence the need for insulin secretion by the pancrease. If to much glucose is left in the blood then it is has a corrosive like effect on the vessels. This causes clogging of the arteries as well as hardening which will not allow vital nutients to get where they need to be. It is like putting 50 weight oil in your car that is designed for 20 weight. It doesnt work to well. | ||

Beezers: Take mach2 word on it. His definition is pretty accurate. I don't feel like going into it too deep. My bro is diabetic and I know alot about insulin. I have used it myself. Basically its a storage hormone. Takes glucose,aminos and lipids from your blood line and stores it. If your body (liver) doesn't need the glucose it will store it as fat. It's not good to make your insulin spike.. You will get fat. There is however 2 exceptions: 1)After training because the muscles are like sponges and they soak up alot of carbs/aminos. 2)When you wake up because liver glycogen is low and basically you have fasted for 8+ hours so your muscles need the nutrients. This is why bodybuilders who inject insulin take it after training and upon awakening. Post more specific questions and I will try to clear it up... ------------------ | ||

Drexx, thanks bro. What I don't understand is why this insulin spike from sweets/sugars or high GI foods is detrimental. I don't get why to avoid simple sugars. What do they do that is harmfull. I will present now an arguemental statement that may be able to spark a response with the answer I seek. "A carb is a carb. They all end up in the same form of energy, glucose. So why does it matter what kind of carb"? | ||

Ok! Because a high gi carb is released very fast in the blood stream. Blood sugar goes up very fast. The pancreas reacts by creating lots of insulin to get rid of it. The problem is that it creates too much insulin. Insulin is a storage hormone and now there is more in your veins so it will store more The only time you want a big spike is after training and maybe when you wake up. If you mix high gi carbs with proteins and fats it changes the gi because they are not digested alone. If 100g of dextrose is taken it will be in your bloodstream in about 5min. That is 100g of glucose in 5 min. If you take 100g of carbs comming from oatmeal it will be released/digested at a slower rate perhaps 10g of glucose per 5 min so it will take 50 min for all the 100g of carbs to be absorbed. ------------------ [This message has been edited by DREXX (edited October 14, 2000).] | ||

Drexx pretty much has it. HIGH GI carbs will create an insulin spike. The insulin will aid in transporting nutrients into the cell. Not only will it store glucose in muscle cells, but it will help store triglycerides in fat cells, making you fat. Insulin doesn't differentiate which cells it will act on. If you constantly have high levels of insulin and excess calories, they will be stored as fat, and more easily than if you had high calories an low insulin levels. Even if you have a calorie deficit in an attempt to lose weight, if those calories are coming from high GI carbs, the high levels of insulin are acting against your attempt to release the triglycerides from the fat cells. By exercising the muscles, and particularly, depleting them of glycogen, you create an environment that increases insulin sensitivity of the muscle cells. Perhaps more muscle cell insulin receptors are created or availabe after intensive exercise. This is why Drexx has stated that high insulin levels created by a high GI carb meal are O.K. after a workout, because the insulin will preferentially fill muscle cells rather than fat cells. | ||

I usually take mine upon awaking in the AM, and after training. I am using 10ius each injection and drinking a TwinLab Ultra Fuel immediately after taking the injection. I have not noticed a remarkable difference yet, am I missing something or doing something wrong? Jae | ||

Actually Jae! I did insulin for 28 days after training at 13iu with 130g Dextrose, 60g Protein, Og Fat and 15g of Creatine. It gave me very good pumps, nice hard and full muscles but barely any weight gain... I was only shooting 4 times a week. I don't know I thought insulin was overated. I probably wont do it again except besides for a carb up for a competition. I feel that it made my muscles nice but didn't make me huge I will stick with metformin and the like since diabetes runs in my family and the risk isn't justified since the gains for me where not that great. I am sure they would have been much better at 2 shots a day for a total of 14 shots a week. ------------------ | ||

When insulin levels rise, GH levels drop. And vice versa. It is also called the fat storing hormone, meaning when levels are high enough- your body is more prone to store fat than normally. |
