Supersonic Keto The idea is that a diet consisting of low glycemic foods lowers insulin levels, which in turn can also help you lose weight. Patrick Holford takes the glycemic index one step further and uses an idea known as glycemic load. The glycemic load takes into account the glycemic index in addition to the complete carbohydrates in a determined quantity of meals. for example, a bowl of steel-cut oatmeal (1 oz.) has 2 GL even as a bowl of cornflakes has 21 GL. Also, half an apple has three GL while a banana has 12 GL. This is a big difference. Holford is a big fan of oats. He states in his e-book The Holford Low GL Diet: "There are specific foods and food combinations that cause rapid weight loss." He claims that you will in no way experience hunger in his weight reduction plan.
