Keeping your blood sugar levels balanced is essential to provide the energy your cells need to function. It's also crucial if you want to avoid pre and type 2 diabetes and for sustained energy, concentration, performance and prevention of other chronic diseases.

Eating lots of sugary foods and simple carbohydrates (cake, biscuits, white bread, pasta, rice, fries, pizza etc.) floods your body with glucose, but the fast kind that rapidly breaks down and swiftly absorbs into your bloodstream. The more consistently you eat in this way, the more sugar circulates in your blood.

You need insulin to control blood sugar levels. Glucose is the body's primary source of fuel. Every time you eat, you release a hormone called insulin via your pancreas, which signals to your cells to absorb the glucose from your blood and use it for energy. If there's too much, it stores it for later use in your liver as glycogen, and also in your fat cells. 

The problem is, the more you eat sugar and carb-laden foods, the more you flood your bloodstream with glucose. Consistently raised blood sugar levels leads to insulin resistance, a precursor to pre-diabetes and diabetes. Insulin resistance is when your cells start ignoring the signal from your insulin, and the excess glucose starts backing up in your liver, fat cells and blood. Not good!

For some of us, regularly skipping meals can also make blood sugar levels dip, causing energy loss and a host of other symptoms. You may find you develop cravings for sweet, carby foods as your body needs rapid replenishment – more on this below.
