One-Week Intensive Cure Daily Plan: Seven Days to Better Health

In the last post, I covered why Dr. Rau designed the One-Week Intensive Cure and why he thinks it works better than fasting. Now let’s get into the actual plan. Chapter 10 of The Swiss Secret to Optimal Health lays out a day-by-day structure that’s surprisingly detailed, so here’s what seven days on this cure actually looks like.

Before You Start: Getting Ready

Preparation matters here. You don’t want to be scrambling for ingredients on Day 2 while your energy is low and your willpower is being tested. Dr. Rau wants you set up for success before you begin.

Stock up on these essentials:

• Organic vegetables. Lots of them. Leafy greens, zucchini, carrots, celery, fennel, whatever is fresh and in season.
• Lemons. You’ll be using these throughout the week.
• Herbal teas. Lime blossom and rosemary are Dr. Rau’s top picks, but chamomile and peppermint work too. Nothing caffeinated.
• Extra virgin olive oil. Cold-pressed, good quality. This will be your main fat source.
• Sea salt or Himalayan salt. Not table salt.
• Ingredients for alkaline broth. Basically a simple vegetable broth made from potatoes, celery root, carrots, and whatever other vegetables you have on hand.

Clear your schedule as much as possible. This isn’t a week to take on extra projects at work, host dinner parties, or push yourself physically. You’re running on minimal fuel, and your body is going to be busy doing internal housekeeping.

Light exercise only. Walking is great. Gentle stretching, yoga, that sort of thing. But no intense workouts, no running, no heavy lifting. Your body doesn’t have the caloric resources for that right now, and pushing it will make you feel terrible.

Cut the caffeine before you start. If you’re a regular coffee drinker, taper off in the days leading up to the cure. Going cold turkey on Day 1 while also drastically reducing your food intake is a recipe for a miserable headache. Start reducing caffeine a few days early so the withdrawal is less brutal.

Days 1-2: The Light Start

The first two days are about easing your body into the restricted intake. You’re not jumping off a cliff here. You’re walking down a steep path.

What you eat:

• Alkaline broth, sipped warm throughout the day
• Small portions of steamed vegetables (think half a plate, not a full meal)
• Raw salads with a simple lemon and olive oil dressing
• Herbal teas between meals
• Water. Lots of water. 2-3 liters minimum.

The portions are intentionally small. You’re giving your body just enough to keep digestive enzymes active and electrolytes balanced, but you’re creating a significant caloric deficit that forces your system to start burning stored toxins and old proteins.

What you’ll feel: Honestly? Probably hungry. And if you haven’t weaned off caffeine, Day 1 might bring a headache. You might feel a bit foggy or tired. This is normal. Your body is adjusting, and it takes a minute. Don’t panic and don’t quit.

Days 3-4: The Detox Kicks In

By Day 3, your body has figured out what’s happening and starts responding. This is when the actual detox ramps up.

What you eat:

• Same pattern as Days 1-2. Alkaline broth, steamed vegetables, raw salads, herbal teas, water.
• Portions stay small. You might notice your appetite actually decreasing, which makes it easier.

What you’ll feel: This is where it gets interesting. As your body starts releasing stored toxins, you might experience some discomfort. Maybe a mild headache. Maybe some digestive rumbling. Maybe your skin breaks out a little. Some people feel achy, like the onset of a mild flu.

Here’s the thing. These symptoms are actually signs that the cure is working. Your body is mobilizing junk it’s been storing in fat cells, tissues, and organs, and processing it for elimination. It doesn’t feel great in the moment, but it means your system is doing its job.

Bathroom visits will increase. Your body is actively flushing waste, and that has to go somewhere. Stay near a bathroom and don’t be alarmed. This is the whole point.

Drink extra water during these days. The more hydrated you are, the easier it is for your body to transport and eliminate the toxins being released.

Days 5-7: The Payoff

This is where most people start feeling the results, and where the difference between this cure and plain fasting becomes really obvious.

What you eat:

• Still the same core pattern. Light vegetable meals, broth, salads, teas, water.
• Some people find they can eat slightly larger portions now without feeling heavy. Your digestion has adapted.

What you’ll feel: Energy starts coming back. Not the jittery, caffeine-fueled energy you might be used to, but a cleaner, steadier version. Mental clarity improves. Many of Dr. Rau’s patients report that by Day 5 or 6, they feel sharper and more focused than they have in months.

Sleep often improves dramatically during these final days. If you’ve been dealing with restless nights or insomnia, this is often when that shifts.

By Day 7, most people feel genuinely good. Lighter, clearer, more energetic. And because your digestive enzymes have been active the entire time (unlike with fasting), you’re ready to transition back to regular eating without the dreaded rebound crash.

After the Cure: Don’t Blow It

This part is critical, and Dr. Rau is very clear about it. Do not celebrate finishing the cure by eating a pizza.

Your digestive system has been running on minimal input for a week. It’s clean, it’s efficient, and it’s ready to work. But it needs to ramp back up gradually. If you suddenly dump heavy food into it, you’ll undo a lot of what you just accomplished.

The transition plan:

• Day 8-9: Slightly larger portions of the same foods you’ve been eating. Add some whole grains like spelt or millet. Maybe some steamed root vegetables.
• Day 10-12: Gradually reintroduce more variety. Legumes, nuts, seeds. Still no meat, dairy, or wheat.
• Day 13+: Ease back into your regular maintenance diet. If you tolerate goat or sheep dairy, those can come back now.

The key word is “gradual.” Your gut flora has shifted during the cure, and your enzyme production needs time to readjust to processing a wider variety of foods. Give it that time.

This Is a Yearly Tool

Something I want to emphasize: Dr. Rau doesn’t present this as a one-time fix. He designed it as an annual maintenance tool. Even his long-term patients who eat well year-round come back to the Paracelsus Clinic or the Al Ronc center once a year to go through this seven-day reset.

And that framing changes how you think about it. This isn’t punishment for eating badly. It’s maintenance. Like getting your teeth cleaned or servicing your car. You do it regularly because things accumulate over time, even when you’re generally careful.

My Take

What I appreciate about this plan is how practical it is. Seven days is doable. The food isn’t exotic or expensive. And the reasoning behind each phase makes sense. You’re not starving yourself, you’re strategically reducing intake while keeping your digestive system active.

The emphasis on preparation is smart too. Most diet programs fail because people start on impulse without the right food in the house or the right week on their calendar. Dr. Rau basically says: plan this like you’d plan a trip. Know what you need, have it ready, and pick a week where you can actually focus on it.

In the next post, we’ll cover the Liver Cleanse, which Dr. Rau recommends pairing with this intensive cure for maximum results.
