If you're still not completely convinced… Juicefast is so much more than just looking good in a swimsuit (even though that’s pretty great too).

Real stories from real Juicefasters

The juices are really delicious, I can't wait to try new combinations. I will try the five-day detox next time, I don't think it should be terrible 😀 I'm delighted with kombucha and we eat snacks.

Yesterday was the last (third) day. I was 82 kg and now I'm 79.3. And that's in just three days. All the juices are delicious and it wasn't as starving as I thought it would be. RECOMMENDED TO EVERYONE

Excellent juices, no problems, one, three or five days, I tried everything and I will order again. Thank you, you are the best.

I just started a three-day detox for weight loss and it's an understatement to say that I'm thrilled. The juices are so delicious, I'm not hungry and I feel great. Thank you so much for this deliciousness :)

My mandatory routine every few months since the very beginning, even before the name change. With juices, I continue my training normally, I just have an even greater burst of energy. I tried juicing fruit and making my own juices, but with all my obligations,...

"I try to eat as varied and healthy as possible, adjusting my meals to my workouts and schedule. If I don’t have time for a proper meal, I always have a BITE ME bar with me! It saves the day every time!"

“I teach my students that what you drink is the first asana. Juicefast detox packs lighten the gut, so every inhale finds more space and every pose flows easier. Sip, breathe, unfold.”

“Most clients don’t have hours to prep balanced meals, yet they still need performance-grade fuel. Juicefast lets me prescribe a two-minute protocol that ticks macros and micros—clean energy in, glycogen topped up, no post-shake slump.”

“When weight-loss stalls, the issue is rarely willpower—it’s metabolic inertia. I use Juicefast’s phased programs to reboot oxidation pathways: high-polyphenol juices first, nutrient-dense meals next. Compliance soars, results stick.”

To maintain your results and long-term health benefits, we recommend:

  • Healthy diet: Stick to nutrient-rich foods – fruits, vegetables, whole grains, lean proteins, and healthy fats. Avoid processed and sugary foods when possible.
  • Regular movement: Exercise helps keep your body and mind in balance.
  • Hydration: Drink enough water daily to keep your organs functioning optimally.
  • Quality sleep: Aim for deep, restful sleep to support recovery and mental clarity.
  • Flexibility: If you slip up, don’t stress. Just return to your healthy rhythm – progress over perfection.

Yes – most of our customers repeat the program every month to maintain optimal health and support their body’s natural reset cycle.

That said, everyone is different. Listen to your body and consult your nutritionist if needed.

Absolutely. Combining different Juicefast products can create a synergistic effect.

For example, you can pair the weight loss fast with the Digestion Fast program (based on celery juice) or add Wellness Shoots for an extra energy and anti-inflammatory boost.

This combo supports digestion, metabolism, and overall energy – creating a full-body reset.

For help with combinations or plans, feel free to contact us at cs@juicefast.com

Weight loss during the detox is highly individual – it depends on your starting point, diet, lifestyle, metabolism, and more.

Most people lose water weight first (especially in the first 3–5 days), followed by fat loss if detox is done over 5–7+ days and followed by clean eating.

The best results come when you prepare before, follow the protocol, and reintroduce solid food properly afterward.

It varies. Many people feel and see changes within the first few days – lighter, less bloated, more energized, clearer skin.

These changes are often linked to water loss, reduced inflammation, and a flood of micronutrients.

Some may see noticeable fat loss within 5–7 days, but sustainable results depend on what you do after the program too – especially eating and movement habits.

Try these :

  1. Symptom journal – Track changes like headaches, bloating, mood, energy, etc.
  2. Weight & body composition – Monitor how your weight and body shape change.
  3. Energy levels – Pay attention to how energized and clear-headed you feel.
  4. Lab tests – If you’re doing a longer detox, bloodwork before and after can show interesting shifts.
  5. Talk to our nutritionist – They can personalize your plan and help assess your progress.
  6. Join our wellness app for additional support

No! Most people are not hungry, on the opposite, some people even report sometimes 500ml of each juice is too much for them…but If needed, you can have a small amount of food – like an apple, carrot, a handful of almonds, or a cup of homemade clear veggie broth.

This won’t ruin the detox and can help you push through.

Yes – we’ve created a Facebook group called “Juicefast community”, a safe space to connect with others with similar goals.

You’ll find support, shared stories, tips, and encouragement from people on the same path.

We don’t recommend full fasting programs for pregnant or breastfeeding women.

However, our products (made from real natural ingredients) can be used as a nutritious addition to a balanced diet – always check with your doctor or nutritionist first.

It’s all about what you do after. Here’s how :

  • Stick to clean eating
  • Stay hydrated
  • Move your body
  • Sleep well
  • Reduce stress
  • See your doctor regularly
  • Practice moderation
  • Keep learning – read, consult, stay aware

In most cases, yes – but always consult your doctor or nutritionist before starting a fast while on supplements or medications.

They can help guide you on proper combinations and timing to avoid conflicts or reduce effectiveness.

Yes – light to moderate workouts are totally fine. In fact, movement can enhance the detox effect.

Just listen to your body and avoid intense training if you feel low on energy.

You can – but we recommend limiting it to one cup of black coffee or green tea in the morning.

Try to use this time to reset your caffeine tolerance.
