GI and weight loss

Why is GI so important for weight loss?

Low GI breakfast cereal You will more than likely have heard the term Glycemic Index or GI, but may not have a clear understanding about what it is.

 Quite simply, GI is a measure of the response that carbohydrates have on our blood sugar levels, which in turn affects our levels of fat storage.

 So, if there’s one thing you should know it’s this:

Low GI food = Low fat stores ↓

High GI food = High fat stores ↑

Ok, so it doesn’t take a scientist then to know that a diet based on lower GI foods is the one to go with if you want to get lean and look amazing.

 The good thing about taking this approach to your nutrition is that it’s sustainable, has great results, and doesn’t involve a complex approach. You really just need to know which foods are low on the GI scale and which foods are high.

 The GI scale runs from 0 to 100 and foods are categorised as per the chart on the right.

 Obviously the aim is to eat as many foods with a GI of 55 or less, and fewer foods above 55. However, the 80/20 rule should always apply as the most important thing is that you find something that is sustainable and allows you to live a life of moderation.

Where to start

 The truth is that small steps make big differences. Simply by reducing your intake of potatoes or replacing white bread for wholegrain bread, bananas for apples, and so on, all helps you lose the pounds and, more importantly, keep them off!

 There are plenty of good books on the market to help you with implementing and sustaining a low GI eating approach. We have included some of our own Amazon recommendations of low GI books on our ‘LFF Shop’ page so it’s definitely worth taking a look and having at least one in your book collection.
