What is the CarbChoice® Advanced?
The CarbChoice® Advanced is your simple, personalised anchor for building a nutrition plan that truly works for you. It reveals how your body uniquely processes carbohydrates, so you can stop guessing how many carbs you should eat.
This report is based on your AMY1 gene, which is like your body’s personal efficiency gauge for digesting starches in foods such as breads, rice, pasta, potatoes and even some fruits. Understanding your personal genetic tendency helps explain why you might respond to carbohydrates differently from your friends or family.
Carbchoice® is key to optimal weight management, steady energy, and overall metabolic well-being. The CarbChoice® Advanced connects these dots for you in a clear, easy-to-read way.
Instead of confusing you with complex genetic data, we present your results as simple eating styles, ranging from low-carb to higher-carb. This makes it quick and easy to find a dietary path that naturally aligns with your biology.
Our goal is simple: to help you achieve better, long-lasting health and maintain a healthy weight through personalized carb guidance that you can actually use every day.
