Do you know what is Glycemic Index (GI)? 

Glycemic Index (GI) measures how quick or slow a carbohydrate-containing food raises blood glucose after consumption.

  • Low GI food : ≤ 55 (slowly digested and release glucose in blood)  
  • Moderate GI food : 56 – 69 (moderately digested and release glucose in blood)
  • High GI food : ≥ 70 (quickly digested and release glucose in blood) 

Benefits of choosing low glycemic index food in your diet

Tired Gir

When you consume a high GI meal your body quickly digests the carbohydrate and releases sugar in blood which causes a spike in your blood glucose levels. The sharp rise and a sharp decline in blood sugar level lead to the feelings of tiredness and sleepiness.

Scientists at the University of Sydney have proven the link between high GI meals and the increase in the proportion of tryptophan – an amino acid known to induce sleepiness.

Suggest to choose a low GI diet as its high fiber and whole grain content can act as a physical barrier that slows down the absorption of carbohydrate providing a gentle and slow release of energy to sustain you across the day.


Happy family

In a study by Warren et. al (2003) among a group of normal and overweight children lunch intake was lower after low GI breakfasts compared with lunch intake after high GI breakfasts.

Whole grain food (low GI option) helps you stay fuller for longer. Eating a meal with a low GI increases gut hormone production which leads to suppression of appetite and the feeling of fullness.



Starving yourself before exercising can actually be detrimental to your body.  You should always eat something before exercising so your body has enough fuel to help you perform at your best.

Consuming a low GI diet will lead to an increase in free fatty acid (blood fat) oxidation and more optimal maintenance of blood glucose levels leading to more sustained glucose availability for working muscles. 

A study carried out by GI Foundation (2014) among 130 people (adolescents – adults) there were significant improvement in performance after taking a low GI meal between 0.5 and 3 hour before exercise. The participants were able to keep going for an average of 22% longer when exercising to exhaustion.1
