Did you know sleep affects weight loss? And hugely so!

In fact, scientists estimate that overweight people who sleep less than 7 hours a day could lose about 6.5 kilos more a year just by sleeping one hour more a night!** Here’s why: 

During sleep, your body draws on fat reserves. The longer and better you sleep, the more fat you can burn. But to get your body to switch into the fat-burning mode, you also need to resist cravings a few hours before going to bed – the longer, the better.

And that’s exactly where our night-time fat burner SHAPEiT FatOut! NIGHT SLIMMER comes in, helping you on all fronts for a maximised fat burn during your night-time rest.


4-in-1 effect on night-time fat burning!

SHAPEiT FatOut! NIGHT SLIMMER helps you lose weight while you sleep. It’s one of the most efficient night-time fat burners, since it boosts fat burning on 4 different levels.


It improves your sleep

This way, you can burn more fat and wake up refreshed. You’ll be more likely to opt for low-calorie snacks during the day, too.


Kicks fat burning into high gear and prevents fat storage

Thanks to the fat-reducing properties of its star ingredient, Garcinia cambogia, which prevents fat accumulation in the body and stimulates the burning of fat reserves.


Stops late-night cravings

Beating the evening urges to raid the fridge will help your body switch into the fat-burning mode. It will also help you relax and prepare for a restful sleep.


Keeps your main fat-burning organ, the liver, in shape

If the liver is overwhelmed, it doesn’t function as well as it should, which results in minimised fat burning. Keeping it in shape helps produce the best possible results.

Clinically proven results: up to 2x* more weight lost

Studies have shown the longer and better we sleep, the more fat we burn.

Research** shows that Garcinia cambogia can significantly boost weight loss. In fact, a clinical study showed that women who took HCA (hydroxycitric acid), the main active ingredient in Garcinia cambogia, lost 2x* more weight compared to those who took placebo.

After 8 weeks* of supplementing, the placebo group lost an average of 1.4 kg*, while the HCA group lost 2.8 kg*!


Lose weight while you sleep!

Most fat-burning supplements contain stimulants, such as caffeine, which means it’s unwise to take them in the evening or late at night. But not our night-time fat burner!

SHAPEiT FatOut! NIGHT SLIMMER contains no stimulants to disturb your sleep, just the opposite! Thanks to lemon balm, it can actively help you fall asleep faster, get good-quality sleep and wake up refreshed.

Use it if:

  • you want to burn fat but can’t seem to be able to do that successfully,

  • you tend to eat (too much) in the evening,

  • you have difficulty digesting calorie-rich food,

  • you crave junk food,

  • you have trouble relaxing before bed, and/or

  • you find it difficult to maintain quality sleep.

How does our night-time fat burner work?

The synergistic mix of 8 targeted ingredients is designed to accelerate your night-time fat burning and produce maximum weight-loss results.

Garcinia cambogia helps reduce hunger, prevent your body from accumulating fat and reduce existing body fat.

Choline contributes to normal function of the liver, your main fat-burning organ, and supports fat metabolism.

Lemon balm has relaxing effects that help with good sleep.

Carob root supports weight loss by curbing hunger and cravings.

Chicory root supports the liver and promotes digestive health, which can contribute to weight loss.

Acacia gum with 90% of soluble dietary fibre makes this night-time fat burner also a high-fibre drink.

Vitamin C supports the immune system and reenergises your body.

Vitamin B6 helps regulate hormonal activity and contributes to normal nervous system function.
