burn fat, fuel energy

What is Sportfasting?

One step closer to your ultimate goal!

Overweight, energy dips, craving sweets? Then switch to fat burning. People who mainly burn fat are better protected against becoming overweight.

Everyone can switch from sugar to fat burning thanks to our scientific combination of fasting and exercise. Together with a Fittergy Coach you train your body to make this metabolic switch. Under supervision you will reduce your food intake, after which you will go on a 3-day (juice) fast in combination with intensive exercise (20-30 minutes per day) and supported by specially developed food supplements.

Your Fittergy Coach will design a personal Sportfasting schedule for your Sportfasting training, which you'll follow for 10 days. After the 10 days, you've made the switch and lost a few kilos, you feel more energized and fit!

"I'm more often at home and that easily leads to eating the wrong foods. Then I take a 10-day program such as Sportfasting or the Vegan Flex. It tackles your overweight fat cells and makes your healthy cells work more effectively again.
Marianne Timmer, Coach, Triple Olympic Champion, and one-time World Champion Sprint.
As a previous top athlete I nowadays have a bit more difficulty to maintain my weight. Frequently Sportfasting gives me a physical restart. It's a bit of a challenge, but with a fabulous payback.
John den Braber, Reporter and ex-professional bicyclist
To me, Sportfasting is a method to overcome my ragged lifestyle and to return to a responsible way of exercising and eating. I will definitely do it again next year.
