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 can't think of anything else but ordering 3-5 days of Detox juices. In addition to cleansing my body a little, I feel lighter, I strengthen my will and the decisions I make with juices.
I took the detox program twice, once for weight loss, once for energy. The juices in both packages are delicious and very filling. At the end of the day I barely manage to drink all 5, if I even manage to. The first time I lost 1.25kg, and the second time 1.6kg. I will definitely take it again after 3-4 months.
Perfectly delicious juices, I felt hungry at the end of the first day of detox, but afterwards I felt perfect. Really recommendable to cleanse the body ❤️
3-day energy detox - and minus 2.9kg. I've been taking your juices for years, from the very beginning with Malešnica while you were still there, and since then I've loved you because it really cleanses the body and I feel lighter and more energetic. And let me mention, with every detox I always trained, even when I had serious leg surgeries, I was on your detoxes and trained and rehabilitated for 4-5 hours and not only did I endure, but I felt phenomenal and was energetic
After two days I felt a change. I have a lot more energy for things like college and the gym, because of my busy schedule I didn't even have time for that.
I was pleasantly surprised by these juices, I did not expect such good results. After just one day of detoxification, I felt better than ever before. Full of energy, it seems that the fatigue has passed.
I was pleasantly surprised by these juices, I didn't expect such good results. After just one day of detox I felt better than ever. Full of energy, the fatigue seemed to be gone.
I ordered a detox energy package for 3 days, but I could barely last 1. I had to snack on something in between (apple, nuts). Since in the second part of the day I was shaking a lot from hunger and sugar drops, and I got a migraine, I didn't continue with the detox. There was no drop on the scale, and I didn't even expect it after 1 day. But I don't even have extra kilos. I simply wanted to do a detox because of the bad food I was eating, which I think I succeeded because for the next 2 days I had stools much more often than usual. I will distribute the remaining juices in such a way that I drink, for example, half with light food during the day, and I will spread them out from 2 to 4 days. Don't throw them away... As for the taste, they are not very very nice, but they are not impossible to drink either.
I ordered the juices for myself, to cleanse my body, and in the end the whole family joined in... We're ordering again, this time for the whole family. :)
It's not hard to endure, it can be done 😁 Real weight loss, after the water returns, I was 2kg after 5 days of detox. All juices are delicious! I would suggest to the sales that they have enlighten juice in independent sales for a month, because I would definitely take it as a substitute for breakfast, because otherwise I don't like to consume it (breakfast as a meal, everything is hard for me). My need for water, daily fluid intake and digestion have improved a lot. I train intensively and it was not a problem for me to endure the training with the diet. The only suggestion is that after the detox, you start eating hard, hard-to-digest food at a slow pace, because it will be harder for you to stomach. All great, recommendations! Ana, Rijeka

need performance-grade fuel. Juicefast lets me prescribe a two-minute protocol

You’ll likely feel a noticeable boost in energy, sharper focus, and less afternoon fatigue. Most users also report improved digestion and better sleep after just a few days.
Many people feel lighter and more energized within 1–2 days, especially if their previous diet was heavy or processed.
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.
Not necessarily. Our Energy Fast juices are nutritionally designed to keep you fueled without heaviness. But if you’re used to large meals, the first day or two might be an adjustment.
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.
Eat whole foods, hydrate well, avoid processed sugar, and get quality sleep. You’ll also feel longer-lasting results if you continue to include fresh juices or smoothies in your routine.
Absolutely. The plan is designed for busy people – grab-and-go bottles make it easy to stay on track even with a hectic schedule.
Yes – we’ve created a Facebook group called “Juicefast zajednica”, a safe space to connect with others doing Juicefast programs.
You’ll find support, shared stories, tips, and encouragement from people on the same path.
