The sugar-body fat connection
The single most significant cause of being overweight is eating too many refined carbohydrates, for example white bread, bagels, white pasta, white rice, biscuits, cakes, sweets, chocolate. It is virtually impossible to be obese on a natural food diet. It is very easy to overeat refined carbohydrates because they are a denser form of calories: an apple contains the same amount of calories as a single teaspoon of sugar. You could quite easily eat 10 teaspoons of sugar in a fizzy drink but you’d be hard pushed to eat 10 apples in one sitting! The best way to prevent being overweight is to avoid refined carbohydrates. The ultimate refined carbohydrate is white sugar.
The key difference between natural foods and refined sugars is that natural foods contain fibre, vitamins, minerals and other nutrients, whereas sugar and refined carbohydrates do not. This is why sugar and refined carbohydrates are often referred to as empty calories. What is more, sugar and refined carbohydrates also deplete nutrients in the body when they are metabolized. For example, every time you eat white sugar, you deplete your zinc and chromium levels as your body needs zinc and chromium in order to make insulin.
Although fat consumption and exercise play a part in weight control, they are not as important as you may think. It is quite possible to lose weight by reducing refined carbohydrates and not making any changes to your fat consumption and exercise routine. However, the Insulin Factor Plan does still recommend moderate exercise and emphasizes the need for good quality fats.
Sugar and diabetes
There is also a strong link between sugar and diabetes. This is because refined carbohydrates encourage the body to produce high levels of insulin, which ultimately exhausts the pancreas so it is unable to make enough insulin to control blood glucose, leading to diabetes.
Sugar and heart disease
Not only does sugar increase your risk of diabetes, but it also increases your risk of heart disease. Interestingly, sugar will actually start affecting the health of your cardiovascular system long before you ever get diabetes. This is because high levels of insulin, normally caused by a diet high in refined carbohydrates, exist for many years before you develop diabetes, and excess insulin is one of the most powerful causes of furred arteries, high cholesterol and blood fats, (triglycerides) and high blood pressure (see chapter 1). Insulin is as responsible for elevated bad cholesterol and blood fats as dietary fat. As you know, there is a strong link between high cholesterol and blood fats, and heart attacks and strokes.
Sugar and tooth decay
Of course, it will come as no surprise that sugar is also the main culprit when it comes to tooth decay.
Digestive problems
Refined carbohydrates are also behind many digestive problems, because they feed unwanted bacteria in the gut. The refined carbohydrates line the wall of the gut and enable bacteria to thrive and survive rather than pass on through. These bacteria contribute to a range of conditions from excess flatulence, appendicitis, inflammation of the gallbladder and poor digestion of fats, abdominal bloating, offensive smelling stools, and even cystitis and interstitial cystitis.
The hostile bacteria cause inflammation in the gut provoking the immune system to produce molecules called cytokines. This is a normal self-defence mechanism. However, an excess of these immune defence molecules causes problems in the same way excess insulin causes problems. They can escape the gut and get into the bloodstream and disrupt the binding of insulin to its receptor cells. Research shows that these cytokines are a significant contributory factor to Insulin Resistance.
This is why the health of your digestive system is an important part of the Insulin Factor Plan.
Surprisingly, the health of your digestive system plays an important part in reversing Insulin Resistance.
But if you are completely appalled at the idea of not being able to eat sugar again, don’t panic! Firstly, it’s more a question of cutting down on foods that contain refined carbohydrates, and secondly it really isn’t as difficult as you think, particularly as there are supplements you can take to stop your cravings – most of my clients who are hooked on sugary things are surprised how easy it can be to give them up.
Summary of key points
Refined carbohydrates including sugar really ARE the bad guys when it comes to your health, particularly regarding Insulin Resistance.
Sugar has been identified as a main cause of weight problems, heart disease, high cholesterol, diabetes, tooth decay and even digestive problems.
To restore your health, it is more a question of cutting down on refined carbohydrates, not necessarily cutting them out completely. In any case, there are supplements to stop your cravings, so it is not just a question of your will power!
3 What’s My Risk of Insulin Resistance?
In this chapter you can find out about your own risk of Insulin Resistance. The first thing you have to do is to work out your Body Mass Index (BMI) and then you can go on to further assess your risk of Insulin Resistance by answering a five-part questionnaire. We’ll also have a brief look at interpreting the results of a proper Insulin Resistance blood test, in case you want to do this, as it will give you a clearer indication of what degree of Insulin Resistance you have. We’ll also look in a little more detail at the major causes of Insulin Resistance in relation to your questionnaire results and which sections you should focus on in your Insulin Factor Plan.
Body Mass Index (BMI)
Although you do not have to be overweight to be insulin resistant, being overweight and having a high proportion of body fat are significant risk factors for Insulin Resistance and heart disease. For this reason, it is helpful to work out your Body Mass Index, or BMI. There are two groups of people for whom a BMI reading is not always helpful or accurate, namely:
