Insulin is a hormone secreted by the pancreas to help maintain optimal blood sugar level. Insulin's job is to remove sugar from the blood and store it, either as glycogen in the muscles and liver or, more frequently, as fat. Insulin is good. It helps maintain balance in the body. However, when triggered at the wrong times and in great amounts, insulin will make you fat. Preventing frequent and intense insulin responses is the single most critical step in reducing bodyfat for many people.
Insulin also has a negative affect on resting metabolic rate. Depending on the frequency and the severity of the insulin response, it may reduce the number of calories burned at rest by as much as eight percent! Over time, this could add up to a significant amount of extra bodyfat.
Carbohydrates are very simple molecules, which digest very quickly and easily. Even the most complex carbohydrate is nothing more than strings of sugars loosely tied together. Digestion of carbohydrates begins right in the mouth with an enzyme called Salivary Amylase, which is located in the saliva. By the time carbohydrates even reach the stomach, digestion is well underway and much of the carbohydrate you just ate is already sugar.
When you eat carbohydrates by themselves, they digest too quickly and the sugar enters the bloodstream all at once, sending your blood sugar level soaring. This sets off an alarm and the pancreas secretes insulin into the bloodstream to take some of the sugar out
Preventing the Insulin Response
The way you consume carbohydrate may be making you fatter than you want to be, but carbohydrate is not the enemy. Depending on how you structure your food consumption, carbohydrate may be stored mostly as fat (bad), stored mostly as carbohydrate in the muscles (good), or not stored at all, but burned as fuel (good). Managing the insulin response is a critical aspect of this. Carbohydrate in the bloodstream provides energy right now. Carbohydrate in the muscles gives energy for tomorrow's workout. DEPLETING CARBOHYDRATE WILL NOT MAKE YOU LEAN.
The key is structuring meals and snacks so that you can consume carbohydrates in your diet, but keep from suddenly elevating your blood sugar level. Three strategies come into play here:
- Choose carbohydrates that digest more slowly and therefore enter the bloodstream gradually.
- Combine carbohydrate with other types of food that digest more slowly, essentially "time-releasing" carbohydrate.
- Consume concentrated carbohydrates, such as sugar, pasta, rice, cereal, bread, corn, rice and potatoes only after workouts. Consumed immediately after workouts, calories from concentrated carbohydrate sources are likely to be stored in the muscles as fuel for tomorrow's workout instead of in your fat cells.
Glycemic Index
The glycemic index (G.I.) of a food is a measurement of how quickly the carbohydrate in that food enters the bloodstream compared to pure glucose. Glucose has a glycemic index of 100. A food that has a G.I. of 70 enters the bloodstream 70% as quickly as pure glucose. For someone trying to lose bodyfat, a diet comprised largely of low G.I. foods prevents excessive insulin secretion and ensures that the carbohydrates in the diet are available as fuel instead of being stored as fat.
A list of the glycemic index of common carbohydrates is at the end of this article. Carbohydrates with a glycemic index of 40 or lower may be considered low G.I. foods, which are the best choices. Carbohydrates with an index between 40 and 70 may be considered moderate G.I. foods and are good choices. Carbohydrates with an index over 70 will tend to trigger an insulin response and should be eaten primarily right after workouts or in combination with lower G.I. foods (to create a combined G.I. of less than 70).

Combining Foods
Protein is the friend of an active person trying to decrease bodyfat. Consuming protein with carbohydrate helps ensure that the carbohydrate is not stored as fat.
Choosing low to moderate glycemic index carbohydrates is a useful strategy for reducing insulin secretion, but properly combining foods in meals and snacks can be just as powerful. Learn to make this strategy a natural part of your lifestyle and you will become leaner.
Carbohydrate is a very simple molecule that digests very rapidly and easily. Protein, on the other hand, is a very large, complex molecule, which digests much more slowly. Remember that when you eat different types of food together, they move through the digestive tract together, being digested and absorbed at the same rate. If you eat protein and carbohydrate together, the protein dramatically slows the carbohydrate digestion. Instead of a large amount of carbohydrate entering the bloodstream all at once and driving the blood sugar level up dramatically, the carbohydrate trickles slowly into the bloodstream. Protein "time-releases" carbohydrate. As digestion occurs, blood sugar is gradually burned off almost as quickly as it enters, preventing quick increases in blood sugar level that cause the insulin response. Blood sugar remains just slightly elevated for a long period of time. This creates the perfect situation: good mood, feelings of energy, minimized hunger, and a slow, steady supply of sugar to be burned with fat to provide the body with energy for daily activities.
Fat digests very slowly, just as protein, so logically it could be combined with carbohydrate to prevent dramatic blood sugar fluctuations. While this will prevent the insulin response, think carefully about the logic behind consuming fat to be sure that the carbohydrate you eat will not be stored as fat. You store fat calories as fat calories instead of storing carbohydrate calories as fat calories. You get fat for a different reason. Fat is the most calorie-dense of all biological fuels, having about 2¼ times more calorie per gram than either protein or carbohydrate. Better to stick with lowglycemic index carbohydrates and combine them with protein in a relatively low fat diet.
Make a habit of eating protein every time you eat carbohydrate (except during workouts), eating concentrated carbohydrates only after workouts, and choosing carbohydrates that fall lower on theglycemic index. Your energy level will increase while the extra pounds melt away.
================================
Insulin’s job is to get energy into cells. For example, after we eat lunch, our body digests it and then releases insulin to carry those freshly digested calories into our cells. Since insulin is activated only when we need to get fuel into our cells, our metabolism “hears” insulin in the bloodstream “communicating” that we have energy on its way to our cells and therefore do not need to use any stored energy—aka burn body fat. So the hormone insulin—not the calories we ate—blocks the burning of body fat. That point is extremely important.
We can cut calories all day and will not burn body fat effectively if we are eating low-quality calories which trigger excess body-fat-storing hormones such as insulin. Why? Hormones like insulin remove our abilityto burn body fat regardless of whether or not we need to according to calorie quantity. That is why scientists refer to the hormone insulin as the “principal regulator of fat metabolism.”
Not only does all the excess insulin destroy our ability to burn body fat, it makes the metabolism resistant to insulin. How does this process work? Compare becoming resistant to the effects of insulin with becoming resistant to the effects of alcohol. When people drink alcohol in moderation, everything is fine. It takes relatively little alcohol to generate the desired effect, so people don’t drink too much of it. However, if people drink too much alcohol, they become resistant to alcohol’s effects. Then they have to drink more alcohol to get the desired effect. This volume of alcohol eventually destroys their liver and makes them gain body fat. This leaves heavy drinkers in an unfortunate place where they have become resistant to alcohol and have to drink an unhealthy amount of it to get the desired effect.
Similarly, when people eat mostly SANE foods and just a little inSANE starch and sweets, everything is fine. It takes little insulin to get energy into cells, so the body doesn’t produce too much of it. However, if people eat mostly starch and sweets, their bodies become resistant to insulin’s effects.
All this excess insulin forms the backbone of the hormonal dysfunction causing us to gain fat. Not only does it crush our ability to burn body fat, it also increases the rate at which we store body fat because excess insulin preferentially puts calories into our fat tissue. This happens because no matter how resistant other tissues become to insulin, our fat tissue is always receptive.
===============================
Sugar (glucose) is a main source of energy for the cells that make up your muscles and other tissues. Glucose comes from two major sources: carbohydrates in food and extra stores in your liver. Carbohydrates come in the form of sugar, starch and fiber. After you eat or drink something with carbs, your body breaks down each type of carbohydrate in essentially the same way, converting it into sugar. The exception is fiber, which passes through your body undigested. The sugar then enters your bloodstream. From there, it enters individual cells throughout your body to provide energy. Extra sugar is stored in your liver and muscles in a form called glycogen.
Two hormones from your pancreas help regulate the level of blood sugar. The hormone insulin moves sugar from your blood into your cells when your blood sugar level is high. The hormone glucagon helps release the sugar stored in your liver when your blood sugar level is low. This process helps keep your body fueled and ensures a natural balance in blood sugar.
Typical menu for a glycemic index dietMany commercial diets are based on the glycemic index. What you can eat depends on the specific commercial diet you follow. Sydney University's glycemic index website doesn't promote specific commercial weight-loss plans or label carbs as good or bad. Rather, it recommends that you use the glycemic index to help you choose what foods to eat and suggests that you:
- Focus on breakfast cereals based on oats, barley and bran
- Choose breads with whole grains, stone-ground flour or sourdough
- Eat fewer potatoes
- Eat plenty of fruits and vegetables
- Avoid oversized portions of rice, pasta and noodles
Results
Weight lossCommercial diets that are based on the glycemic index say that you'll lose weight without having to count carbs or calories. Foods that have a low glycemic index ranking are said to make you feel full longer and to balance your blood sugar.
Results from research studies are mixed, and some studies have been of poor quality. Some studies show that calorie for calorie, there's little difference in hunger after eating a high GI food or a low GI food. Other studies, though, conclude that you're more likely to lose weight and reduce your body mass index (BMI) with a glycemic index diet than with a traditional diet, even if you're obese and need to lose a significant amount of weight. That may be, at least in part, because it's easier to stick to the glycemic index diet for the long term since it's not considered an extreme diet.
Still other studies suggest that there's little if any evidence that having an elevated blood sugar level leads to weight gain if you're healthy. These studies note that insulin is vital to good health, and that insulin becomes a problem only when insulin resistance develops. Insulin resistance doesn't develop from eating certain carbs or proteins but from being overweight. Weight loss from any type of diet improves blood sugar control.
Health benefitsProponents of the glycemic index diet say that you can improve or reduce the risk of serious diseases, including diabetes and cardiovascular disease.
Almost any diet can reduce or even reverse risks factors for diabetes and cardiovascular disease — if it helps you shed excess weight. And most weight-loss diets can improve blood cholesterol or blood sugar levels, at least temporarily.
On the other hand, the glycemic index doesn't rank foods according to how healthy they actually are. Indeed, some foods with the preferred lower GI ranking may, in fact, be less healthy because they contain large amounts of calories, sugar or saturated fat, especially packaged and processed foods. Both potato chips and ice cream, for instance, have a lower glycemic index ranking than do baked potatoes, even though baked potatoes are generally considered healthier. So while lower GI items may help blood sugar balance, choosing them indiscriminately could lead to other health problems.
Other concernsOne major concern with the glycemic index is that it ranks foods in isolation. But in reality, how your body absorbs and handles carbs depends on many factors, including how much you eat; how the food is ripened, processed or prepared; the time of day it's eaten; other foods you eat it with; and health conditions you may have, such as diabetes. So the glycemic index may not give an accurate picture of how one particular food affects your blood sugar. Glycemic load is a related concept that scores a food product based on both carb content and portion size. But the larger the portion size, the greater the calories consumed whether the glycemic index is high or low.
It also can be difficult to follow a glycemic index diet on your own. For one thing, most foods aren't ranked by glycemic index. Packaged foods don't generally list their GI rank on the label, and it can be hard to estimate what it might be. And for some types of food, the glycemic index database has multiple entries — you may not be sure which entry is accurate.
On the other hand, many generally healthy foods are naturally low on the glycemic index, such as whole grains, legumes, vegetables, fruits and dairy products. If you eat a healthy diet, based on fresh foods that aren't highly processed, you may get the same benefits of the glycemic index diet. But if you need extra guidance toward healthier choices, the glycemic index may help.

============================
lycemic Index Controversy
The GI is not a perfect tool and is no guarantee of healthy fare. Brown and white rice rank comparably on the index scale as do white and whole wheat bread, yet clearly the whole grain choices are healthier.
Some scores are confusing. For example, carrots are a nutrient-rich, high-fiber vegetable that can range from low to high on the GI scale. Likewise, some candy that includes nuts gets a better GI score than a potato. Ripe bananas have higher GI scores than under-ripe bananas. Cook pasta al dente and it ranks lower than fully cooked pasta.
Not only do the food scores vary, but so does the response from person to person. It can even vary within the same person from day to day, according to research reported in the June 2007 issue of Diabetes Care.
Furthermore, no one eats a single food in isolation. When carbs are paired with other foods, it impacts how blood sugars are affected -- that's the glycemic load, which ranks foods based on carbs and portion size.
Some nutrition experts don’t put much stock in the GI as an effective weight loss tool because of all the variability associated with the numbers.
"Using the GI to lose weight is unnecessarily complicated, and it does not simplify the task of choosing healthier food to lose weight or manage blood sugar," says Hope Warshaw, MMSc, RD, a certified diabetes educator and author of books about diabetes including Diabetes Meal Planning Made Easy.
Some experts see the glycemic index as just another gimmick because there is little evidence that an elevated blood sugar level leads to
weight gain if you are healthy.
===============================
Oil is pure plant-source fat, whether it is olive, canola, sunflower, sesame, peanut, coconut, soy or corn. One ounce of oil is about 28 grams of fat because 1 ounce converts to about 28 grams in the metric system. It makes no difference to this equation whether the fat is saturated or unsaturated. It is probably more helpful, and certainly more accurate, to think of oil as being fat, rather than containing fat. Dietary fat by itself, including these foods, does not cause insulin release.
Two tbsp. butter, about 1 ounce, contain 22 grams of fat and no carbohydrates or protein. The other 6 grams in the 28 grams ounces of butter is made up mostly of water, along with a small amount of milk solids. Butter eaten by itself does not stimulate the release of insulin.
Nearly all of cream cheese's macronutrient value is in fat, as 1 ounce of cream cheese contains 9 grams of fat, but only 1 gram of carbs and 2 grams protein. That would mean that it stimulates little insulin release.
One ounce of macadamia nuts contains 21grams fat, with only 4 grams carbohydrate and 2 grams protein. Almonds, by contrast, contain only 15 grams fat, coupled with 5 grams carbohydrate and 6 grams protein. That means that although macadamia nuts will stimulate some insulin production, it won't be as much as almonds. Dr. Robert Atkins, creator of the low-carbohydrate Atkins Diet, recommended that people who are extremely resistant to the action of insulin eat macadamia nuts, which have the highest ratio of fat to carbohydrate and protein combined.
