Study finds CurraNZ mimics the fat burning effects of exercise up to 61%

on September 01, 2023

BRITISH researchers have discovered that CurraNZ can ‘turn on’ resting rates of fat burning and mimic the effects of exercise1, all without leaving the sofa. 

The discovery shows CurraNZ Original can increase fat burning up to 61% in sedentary adults.

For the individuals in the study, the cumulative effects over a year would burn an additional 0.5 kg – 20.8 kg of fat, without breaking a sweat.  

With one in three New Zealand adults considered obese, the stunning finding heralds a breakthrough in the fight against obesity as a supplement to support diet and exercise programs.

However, for most people, diet and exercise regimes are often unsuccessful, so easy, cost-effective health strategies for inactive adults are of great interest for weight management strategies in the fight against Type 2 Diabetes.

Described as an ‘extraordinary health finding for daily life’, three-quarters of the participants displayed fat burning improvements normally associated with one-three months of daily endurance exercise.

In the study, researchers tested 16 healthy and physically active males at rest, following 14 days’ intake of 600mg of the CurraNZ supplement.

 Findings showed CurraNZ led to:

  • Average fat burning increases of 21%
  • Individual responses of up to 61%
  • Three out of four people exhibited improved fat burning capacity

Lead researcher, Mark Willems, Professor in Exercise Physiology at the University of Chichester, says: “Based on the premise that the supplement is effective for six-ten hours of the day, outside of eating periods (when the effects would be eliminated), this could contribute to burning up to an additional 6.9 kg of fat in a year for some people.

“Plus, we have seen in exercise-based studies that it is even more effective in women, so we can expect this to be effective in both genders.

“This is extraordinary. If you’re trying to increase all your healthy habits and using diet and exercise to lose weight, some can turn on your fat burner all the time with New Zealand blackcurrant extract. In other words, it can be a serious tool for those seeking fat loss, without doing anything extra.”

New Zealand Blackcurrants are a rich source of anthocyanins with 1.5 times the concentrations of European-grown varieties. The polyphenol compounds play an important role in energy and fat metabolism. 

As well as providing metabolic health benefits associated with exercise, the effects are also relevant to sports performance. With over 10 studies showing it improves fat burning in brisk walking, running and cycling studies, CurraNZ is also popular with active people and athletes.


Scientist: 'It all adds up! This is an easy way to improve fat loss'


Professor Willems adds: “Not everyone is interested or capable of building exercise into their day and in this case, it’s significant that blackcurrant can enhance fat oxidation across the course of 24 hours.

“It all adds up, particularly when weight loss above 5% in overweight and obese individuals is considered clinically meaningful. It appears blackcurrant could be an easy way to improve metabolic health and boost fat loss in people. It can support body weight management strategies”.

“The fact that you get a known amount from using a supplement is a strength and a practical way to include these valuable plant compounds in your diet.”

Conventional wisdom shows diet and exercise are the top two strategies for weight management. Combining this approach with a natural supplement that helps the body favour fat as fuel, CurraNZ now rightly deserves to be considered a serious intervention for weight management.
