Don't feel at home in your body any more, and low on energy?

I stood in front of the mirror and just didn't feel good in my skin. I couldn't even put a name to it. Just this feeling: something isn't right any more.

I'd tried so much over the last few years. Eating less. More exercise. No carbs in the evening. Some shakes from the internet. It lasted two weeks every time, sometimes three. Then I was right back where I started. Just more frustrated.

At some point I stopped trying. Told myself: that's just how it is. At my age. With my daily routine. It just doesn't work any more.

Then a friend said something that stuck with me: "Stop trying to change everything. Change just one thing. Your morning."

That "I don't feel good in my skin any more" feeling. You notice it when you get dressed. When you look in the mirror. In the photo where you hardly recognise yourself.

And then the cycle: you set yourself a goal, stick to it for a few days, fall back and get annoyed with yourself. Next time you start even more motivated and fail even faster.

At some point you stop trying. And tell yourself: maybe I'm just like this.

But you were never the problem. Not your willpower, not your discipline.

It was the approach. Changing everything, giving up everything, turning your whole life upside down. Nobody can keep that up. Not with a job, not with a family, not with a real life.

So what does work?

Most breakfast options, whether toast, muesli, croissant or yoghurt with granola, are largely made up of fast carbohydrates.

That sets off a chain reaction:
Your blood sugar shoots up after breakfast. Insulin brings the sugar down. And then your blood sugar drops again, often even lower than before.

You know the feeling: the energy slump around 10 am. Reaching for coffee. Or a snack. And then the next dip.

A study in the journal Frontiers in Nutrition measured this: people who restrict their eating window in the morning have blood sugar peaks that are 12 mg/dL lower per day on average. [1] What that means: fewer cravings, fewer dips, steadier energy through the morning.

There is a process in your body that breaks down damaged cell components and replaces them with new ones. Autophagy. Literally: "self-eating". The Japanese cell researcher Yoshinori Ohsumi received the Nobel Prize in Medicine for it in 2016. [2]

The catch: this process only kicks in when your body isn't busy digesting. And that's exactly where half-day fasting comes in:
You give your body a break in the morning, so it can take care of the things it otherwise has no time for.

That this works is now well documented. A large review in the Lancet journal eClinicalMedicine evaluated a total of 23 meta-analyses on intermittent fasting in 2024. That's hundreds of individual studies with thousands of participants. [3]

You swap your breakfast for a cold-pressed juice and a concentrated shot. From lunchtime you eat normally, whatever you like.

No calorie counting, no skipping lunch. From midday, nothing changes.

What changes: in the morning, instead of 400 to 700 calories from carbohydrates, you get concentrated nutrients. That's about as much as a whole lunch, which you don't skip but replace with something better. Real fruit and vegetables, cold-pressed. Your body gets what it can actually use.

14 days is enough to turn it into a routine. Not because some coach says so, but because it fits into everyday life. You change one meal. The rest stays as it is.

The three key nutrients: vitamin B6, B12 and magnesium. All three are proven to contribute to the reduction of tiredness. Plus vitamin C for energy metabolism* and zinc for metabolism.

Plus collagen, biotin, vitamin D3, K2 and vitamin E for cell protection and skin.

Instead of empty calories, your body gets what it needs in the morning. And you still have something in your stomach. No starving, no empty stomach.

Sounds good, but who has time to press juice in the morning?

Nobody. That's exactly why the frank. half-day cleanse exists.

14 cold-pressed juices (330 ml), a different one every morning. Plus one bottle of Wake Up Call Shot (500 ml), enough for all 14 days.

Your morning then looks like this:

1. Get up, drink a glass of water
2. Wake Up Call Shot (approx. 25 ml)
3. Wait 15-30 minutes, then enjoy your juice
4. Until lunch: only water or unsweetened tea
5. From 12 pm: eat normally

The whole thing is now available at a special price of €69 instead of €75.90. That's €4.93 per day, less than your coffee on the go.

All juices are cold-pressed, never heated, and preserved using the HPP process. No additives. 10 different flavours, from Marvellous Greens to The Crocodile to Hotel Paradiso.
