Formula 1 is a delicious, easy-to-make shake mix that provides an ideal balance of protein, fibre, vitamins, and minerals. Around the world, 5.3 million Formula 1 shakes are consumed every day.

Formula 1 protein shakes can be used in a number of ways, such as:

·         A quick, balanced meal for breakfast, lunch or dinner

·         A meal replacement for weight loss*

·         A supplement for weight gain or upping your protein intake

·         A way to fuel before or after exercise

·         A means to improve your dietary balance

What Is Formula 1?

Formula 1 is a complete, convenient meal that provides the nutrients your body needs. Its plant-based protein formula was developed by nutritionists and food scientists and is rooted in the latest research showing the efficacy of meal replacements, along with diet and exercise, as a solution for achieving a healthy weight**. According to a systematic review and meta-analysis of 14 studies, the University of Oxford found that programs incorporating meal replacements led to greater weight loss compared to alternative diets.

But a Formula 1 shake can be a part of anyone’s balanced daily regime. Whether you’re focused on shedding pounds, building up muscle, maintaining a good diet, or all of the above, Formula 1 is a key addition to your routine of smarter eating and regular exercise.

Formula 1 and Its Glycaemic Index Value

The Glycaemic Index (GI) is a method that quantifies the effects of carbohydrate-rich foods on the sugar levels in your bloodstream. When these foods are digested and absorbed, the end result is a rise in blood sugar (or, blood glucose), which serves as the primary fuel for your muscles and brain. Since they don’t all affect blood sugar the same way, the GI is used to rank foods according to how much – and how rapidly – they cause the blood sugar to rise after they’re eaten.

Low GI foods, with a GI of 55 or less, include non-starchy vegetables, whole grains, beans and lentils, apples, berries, and oranges. They release carbohydrates more slowly into the bloodstream, so the rise in blood sugar is more modest and energy levels are more sustained. In addition, all flavours of our original Formula 1 carry the Low Glycaemic Index logo and are tested by the Sydney University’s Glycaemic Index Research Service. For individuals who follow a carbohydrate-restricted diet, this information can be helpful in meal planning.
