CarbChoice – How can it help you?



  • World-leading DNA science to help eliminate the trial and error process of determining the best nutrition and exercise and regime for you.
  • Helps fast-track your goals – whether for better health, weight loss, or improved fitness (or all of these), as the results are specific to your genetic makeup.
  • Shows the level of salivary amylase activity (an enzyme that breaks down and processes starchy carbohydrates) to predict the body’s ability to produce it.


CarbChoice created by Fitgenes, is a quick home DNA kit that can assist in determining your natural genetic ability to process starchy carbohydrates. This helps fast-track health goals whether for better health, weight loss, improved fitness levels (or all of these).

Carbohydrates are the main source of energy for our body, especially the brain. There are two kinds of carbohydrates – complex and simple. 

  • Complex carbohydrates take longer to break down during digestion, high in fibre, and produce a slower release of energy. 
  • Simple carbohydrates are digested quickly to increase energy fast, low in fibre and nutrients and often high in sugar.

Carbohydrates in foods are converted into glucose during digestion supplying this required energy. Knowing how well your body processes carbohydrates is the key in helping eliminate the trial and error process for your best health. 


Scientific studies indicate some individuals have a better tolerance to process starchy carbohydrates than others. This is due to a variation in the human salivary alpha-amylase gene (AMY1). A lower level of salivary amylase activity can demonstrate reduced breakdown of starchy carbohydrates, leading to weight gain, feelings of fatigue, mood changes and difficulty concentrating. Higher levels show the reverse – individuals feel well, and the starchy carbohydrates have less impact on weight management and insulin levels.


We each have specific DNA that gives a blueprint for protein (amino acids) to be created. These amino acids become the building blocks for our body to function.

  • A CarbChoice score unique to you (1–9+). Your analysed DNA determines a ‘Copy Number Variation’ for your amylase gene, which calculates how many copies of the amylase gene you have.
  • Indicates your potential disposition for processing starchy carbohydrates
  • Will give guidance of foods and ingredients to include or avoid to support optimal starchy carbohydrate processing
  • What foods to increase your amylase levels for better processing.
  • How you can get fit faster based on better carbohydrate management, as you learn about your GENES!

“You can’t change your genes, but you can change how your body responds”.

Fitgenes, is a world leader in developing DNA-based fitness solutions.
FitGenes’ scientists have been researching and producing DNA-based fitness solutions since 2009.
Fitgenes is respected for its data integrity and privacy of DNA results.


We understand the importance of privacy and data protection and we manage subject data to maximise security. Genetic data are stored in an electronic database. Fitgenes utilizes best-practice methods and mechanisms such as firewalls, encryption, intrusion monitoring, and passwords to protect electronic information such as patient information and testing data. Multiple physical security methods such as locking devices and 24 hour premise monitoring are also employed.
