Your body has three main sources of energy. It can burn fat, glucose (carbohydrate), or protein.
High levels of dietary carbohydrates, also known as high glycaemic load foods (e.g. sugars and starchy foods such as bread, rice, pasta and potatoes), work with the hormone insulin to 'switch off' fat burning and increase fat gain.
It becomes virtually impossible to lose fat if you have raised insulin levels.
When your body’s blood sugar and insulin levels are low enough you will switch to a higher level of fat burning.
To burn fat you need to restrict high glycaemic load foods to a level where your body will produce less of the hormone insulin thereby increase the rate of fat burning. Eating less food is not the answer; you need to specifically reduce the high glycaemic index, carbohydrate-rich foods in order to 'switch on' fat burning.
