Glycemic Load, Glycemic Index, and Insulin Index Explained

Glycemic Load, Glycemic Index, and Insulin Index Explained

Glycemic load and glycemic index are variables that measure the actual impact of foods that contain carbohydrates on blood glucose levels. The insulin index of a food demonstrates how much it elevates the concentration of insulin in the blood.

These terms are often used by people who are suffering from diabetes to control their blood sugar levels.

Many diabetic patients actually monitor and control their blood sugar levels by avoiding high-carb foods altogether and choosing to adopt a low carb diet.

In a related study that compared this type of diet to a diet with an average carb intake, over 90% of the individuals in the low-carbohydrate group reduced or totally eliminated their need for diabetes medications.

The Glycemic Index

The glycemic index is simply a measurement of how quickly a carbohydrate food raises blood sugar compared to the same amount of glucose.

The amount measured is the area under the “two hour curve” when blood glucose is measured for two hours after a meal. The bigger the area, the faster that particular carbohydrate raises blood sugar.

If a food has a high glycemic index (GI), it means that the food is digested and turned into blood sugar quickly. If it has a low GI, it happens slowly.

The way the scale works is that 50 grams of glucose is assigned a GI score of 100. Then other foods are measured and compared to glucose. For example, a food that raises blood sugar 40% as much as glucose is assigned a score of 40.

Many things can affect the glycemic index of a food. For example, it will be lower if consumed with fat or fiber. It will also depend on the individual and the ripeness and cooking method of the food.

Foods with a lower glycemic index (fruit, whole grains) tend to be healthier than foods with a higher glycemic index (candy, white bread), and eating foods with a low GI is correlated with improved health. This has a lot of exceptions, however.

The Glycemic Index Scale:

  • Low: 55 or less
  • Medium: 56-69
  • High: 70 or higher

Check out this database if you want to find the glycemic index or glycemic load of particular foods.

The Glycemic Load

Another system known as the Glycemic Load (GL) is much better for predicting blood glucose levels after meals because it also incorporates serving sizes.

It is simple to figure out the Glycemic Load if you already know the GI of a food and its carbohydrate content. You simply multiply the Glycemic Index with the amount of carbohydrates in grams and divide by 100.

Glycemic Load (GL) = Glycemic Index (GI) * Carbs in grams / 100

For example, apples with a GI of 40 and a carb count of 16 grams: GL = (40 * 16) / 100 = 6.4

Therefore foods with a high GI and/or high carb content have a higher glycemic load, while foods with a low GI and/or low carb content have a lower glycemic load.

The Glycemic Load Scale:

  • Low: 10 or less
  • Medium: 11-19
  • High: 20 or higher

The Insulin Index

The Insulin Index measures blood levels of insulin after meals.

These levels are usually correlated with glucose levels, with some exceptions. Some protein-containing foods such as beef can cause a higher insulin response than certain carbohydrate-containing foods.

The Insulin Index measures the insulin response to various foods, relative to the insulin response to white bread, which is assigned a score of 100.

A food that raises insulin more than white bread has a score over 100, while a food that raises insulin less than white bread has a score of less than a hundred.

Some examples: porridge with an insulin index of 40 is much less than white bread, potatoes with 121 are higher than white bread, and beef with a score of 51 is less than white bread but higher than porridge.

Why Is Goal Setting Important to a Truly Fulfilling Life?

Why Is Goal Setting Important to a Truly Fulfilling Life?

In Personal Development-speak, we are always talking about goals, outcomes, success, desires and dreams. In other words, all the stuff we want to do, achieve and create in our world.

And while it’s important for us to know what we want to achieve (our goal), it’s also important for us to understand why we want to achieve it; the reason behind the goal or some would say, our real goal.

Why is goal setting important?

1. Your needs and desire will be fulfilled.

Sometimes when we explore our “why”, (why we want to achieve a certain thing) we realize that our “what” (our goal) might not actually deliver us the thing (feeling, emotion, internal state) we’re really seeking.

For example, the person who has a goal to lose weight in the belief that weight loss will bring them happiness, security, fulfillment, attention, popularity and the partner of their dreams. In this instance, their “what” is weight-loss and their “why” is happiness (etc.) and a partner.

Six months later, they have lost the weight (achieved their goal) but as is often the case, they’re not happier, not more secure, not more confident, not more fulfilled and in keeping with their miserable state, they have failed to attract their dream partner.

After all, who wants to be with someone who’s miserable? They achieved their practical goal but still failed to have their needs met.

So they set a goal to lose another ten pounds. And then another. And maybe just ten more. With the destructive and erroneous belief that if they can get thin enough, they’ll find their own personal nirvana. And we all know how that story ends.

2. You’ll find out what truly motivates you

The important thing in the process of constructing our best life is not necessarily what goals we set (what we think we want) but what motivates us towards those goals (what we really want).

The sooner we begin to explore, identify and understand what motivates us towards certain achievements, acquisitions or outcomes (that is, we begin moving towards greater consciousness and self awareness), the sooner we will make better decisions for our life, set more intelligent (and dare I say, enlightened) goals and experience more fulfilment and less frustration.

Advertising

We all know people who have achieved what they set out to, only to end up in the same place or worse (emotionally, psychologically, sociologically) because what they were chasing wasn’t really what they were needing.

What we think we want will rarely provide us with what we actually need.

3. Your state of mind will be a lot healthier

We all set specific goals to achieve/acquire certain things (a job, a car, a partner, a better body, a bank balance, a title, a victory) because at some level, most of us believe (consciously or not) that the achievement of those goals will bring us what we really seek; joy, fulfilment, happiness, safety, peace, recognition, love, acceptance, respect, connection.

Of course, setting practical, material and financial goals is an intelligent thing to do considering the world we live in and how that world works.

But setting goals with an expectation that the achievement of certain things in our external, physical world will automatically create an internal state of peace, contentment, joy and total happiness is an unhealthy and unrealistic mindset to inhabit.

What you truly want and need

Sometimes we need to look beyond the obvious (superficial) goals to discover and secure what we really want.

Sadly, we live in a collective mindset which teaches that the prettiest and the wealthiest are the most successful.

Some self-help frauds even teach this message. If you’re rich or pretty, you’re happy. If you’re both, you’re very happy. Pretty isn’t what we really want; it’s what we believe pretty will bring us. Same goes with money.

When we cut through the hype, the jargon and the self-help mumbo jumbo, we all have the same basic goals, desires and needs:

Joy, fulfilment, happiness, safety, peace, recognition, love, acceptance, respect, connection.

Advertising

Nobody needs a mansion or a sport’s car but we all need love.

Nobody needs massive pecs, six percent body-fat, a face lift or bigger breasts but we all need connection, acceptance and understanding.

Nobody needs to be famous but we all need peace, calm, balance and happiness.

The problem is, we live in a culture which teaches that one equals the other. If only we lived in a culture which taught that real success is far more about what’s happening in our internal environment, than our external one.

It’s a commonly-held belief that we’re all very different and we all have different goals — whether short term or long term goals. But in many ways we’re not, and we don’t; we all want essentially the same things.

Now all you have to do is see past the fraud and deception and find the right path.
