The Low GI Diet Plan


The Glycemic Index Diet, also known as the low GI diet is based on the effect different foods have on your blood sugar levels, which has been associated with obesity, heart disease, diabetes, and bad cholesterol levels1.

Low GI foods take longer to burn as energy, and get released slower into your bloodstream which helps keep cravings and weight gain at bay.

Fitium is an online personalised diet plan which takes advantage of the Glycemic Index and incorporates these principles into a complete diet plan tailored to your diet goals.

How Does The Low GI Diet Work?

Studies have found that contrary to popular belief, fat storage doesn't necessarily happen because of too many calories being digested. What these have found is that glycemic response has a direct effect on whether food consumed is burned for energy through muscle or stored as fat2.

Here is a simplified illustration of how this works:

  • When food is digested, it is converted by your body into glucose
  • This glucose is then released into your bloodstream, the speed of delivery will be            based on the glycemic response of the foods you digested
  • If more glucose is delivered than your body can handle, it will be diverted into fat           storage

The goal is therefore to make sure that the foods we consume deliver a constant stream of glucose, avoiding spikes in our blood sugar levels.

Putting the Low GI diet into practice

The Glycemic Index3 was developed to measure the glycemic response of carbohydrates, and to provide a means for comparison. The higher the GI, the more glucose is released into the bloodstream.

You can find a full Glycemic Index table in the resources, but for the sake of simplification you can class foods in the following GI index ranges:

  • Protein and Fat sources don't contribute to increased Glycemic load
  • Non starchy vegetables, legumes and fruit tend to have a lower GI
  • Whole grains, whole wheat and starchy vegetables tend to have a medium GI
  • Sugar, white bread, white rice, refined grains and glucose tends to have a high GI

Is the Low GI diet healthy?

The Glycemic Index was originally developed to help diabetics manage blood sugar levels, and according to the Diabetes UK organisation, a diet which includes lots of Low GI foods can help prevent the risk of diabetes.

Research has also shown that lower GI diets can help improve levels of good cholesterol, and help prevent blood sugar spikes associated with obesity, heart disease, and bad cholesterol levels 1.

Is the Low GI diet for you?

Following a low GI diet can bring a lot of health benefits, help reduce cravings, and help promote a healthy metabolism essential for effective fat burning.

But the low GI diet has some limitations, for example:

  • Not all low GI foods are healthy and beneficial to weight loss, as an example milk chocolate has a low GI rating
  • It can also be quite difficult to identify the GI value of a meal, as different food combinations, and preparation methods can affect the GI value of a food.

But combined with sound nutritional judgement, you will benefit from making some of the changes suggested in this diet.
