Group 3-day Cleanse Report - New Year New Gut

We conducted a group 3-day cleanse. This time, it was specifically with participants who happened to have experience with fasting, and they were all Japanese. The results were remarkable.

Let’s see how this group cleanse was conducted and the key factors contributing to the successful outcomes.


How the group 3-day cleanse was conducted?

On day 1 and day 2, we had a light meal to prepare for the cleanse. From day 3 to 5, we had 3–5 servings of R’s KOSO per day without any food. After the cleanse, we had post-cleanse meals (meals without red meat, fish, dairy products, processed food, fatty meals, deep-fried food, sweets, gluten, sugar, caffeine, and alcohol).

The reasons why you joined the group cleanse

◯Participant A

I had been contemplating the idea of resetting my body. I received an invitation email for the group cleanse when I was thinking that it might be a good time to try fasting for the purpose.

◯Participant B

It was the perfect timing as I indulged in heavy meals such as hamburgers and Mexican food during a trip. My weight had reached an all-time high.

◯Participant C

I thought it was a good opportunity to have a break from coffee, detox from overindulgence, and reduce the amount of food I consume.


How was the preparation phase?

◯Participant A

Reducing rice intake and getting vegetarian protein such as eggs and natto beans instead of meat were not issues for me. However, the preparation involved some minor inconveniences, such as buying a daikon radish and preparing dishes in advance (as they would spoil during fasting if not cooked) to ensure a higher vegetable intake.

◯Participant B

Actually, the preparation phase turned out to be the most challenging. I focused on a menu centered around rice, vegetables, and fruits. Although I planned for a two-day preparation period, I experienced headaches and a general feeling of fatigue on both days. On the second day, I even vomited, making me contemplate whether to proceed with fasting. However, since I woke up feeling refreshed on the morning of the following day (the first day of fasting), I decided to go ahead with the plan.

Notably, as I refrained from consuming coffee and wheat products during the preparation phase, I wondered if the early onset of positive reactions might be attributed to avoiding caffeine or gluten.


How was the fasting experience?

◯Participant A

During the fasting period, I often sipped on R’s KOSO diluted with sparkling water and plain hot water. I managed well without much hunger or headaches. Despite the constant battle with sleepiness, I fulfilled my role as a cook for the family.

◯Participant B

The cleansing period was much easier than the preparation phase. I stayed hydrated with R’s KOSO diluted with sparkling water. I occasionally had decaf black coffee and organic herbal tea so I can enjoy the different flavor. I also remained active, engaging in hiking, long walks, and yoga. Throughout this period, my heightened sense of smell made me more aware of various scents.

◯Participant C

On the first day, I felt sleepy, experienced intense cold, and noticed my tongue turning white.

◯Participant D

Despite experiencing drowsiness and headaches on the first day, hunger was not much of an issue. The second day went smoothly during the day, but I struggled with a bit of hunger in the evening. On the third day, I felt more accustomed to the routine. I felt a little hungry thinking about breaking the fast with umeboshi (pickled plums) in the evening.


How was the recovery meal phase?

◯Participant A

I found the recovery meal phase quite satisfying, as I enjoy congee and simply having solid food in my mouth felt fulfilling, with no strong desire to consume large quantities.

◯Participant B

For the first meal, I boiled thinly sliced turnips in a light broth (using additive-free dashi) and topped them with pickled plums. Subsequently, I focused on a diet centered around vegetables, fruits, and tofu. Even without much seasoning, the natural flavors of the ingredients were surprisingly delicious, and I felt my sense of taste had become more sensitive.

◯Participant D

On the first day after the fasting, I started my day with R’s KOSO. I had tomato and shiso salad with R’s KOSO for lunch. I went out for dinner. Though I initially intended to stick to tofu and vegetables at the izakaya restaurant, I ended up eating sake-steamed clams, stewed octopus, and sashimi. At least, I kept the fat intake minimal. On the second day post-fasting, I began with R’s KOSO in the morning. I had soup at a restaurant for lunch. I had 20g of oatmeal in a minestrone for dinner. I also included yogurt in my meals.

Did you experience any changes?

◯Participant A

I lost about 2 kilograms. I used to love Boba tea, but I don’t have a craving for it anymore. I have a sweet tooth, but I didn’t experience strong cravings for sweets during the cleanse possibly because I was enjoying the sweet flavor of R’s KOSO. I had a blood test two weeks after the cleanse, and I was surprised to see that my LDL cholesterol level had dropped by around 20 points. However, it’s still higher than the standard, so I am planning to improve my diet and reduce my weight. 

◯Participant B

My taste buds became more sensitive. I started to enjoy eating raw vegetables and boiled eggs without adding flavors. I feel like I can appreciate the taste more. 

I used to drink coffee every day, but now I opt for decaf when I do.

My weight initially dropped by 2.5 kilograms, then increased by 0.5 kilograms. My mother told me that my face became sharper.

◯Participant D 

I lost 2 kilograms and haven’t gained it back. Around the third day after breaking the fast, both my face and body became smooth.



This time, as participants had experience with cleanses, we successfully completed the cleanse without major issues.

Participants experienced an improvement in sensitivity to the flavor which allows them to enjoy the natural flavors of ingredients. This helps them reduce the consumption of salt, sugar, oil, and similar items.

Although its connection to the cleanse is not clear, one of the participants reported her cholesterol level decreased.

While many experienced weight loss, there seem to be additional long-term benefits, such as improvement in digestive health, changes in taste preferences, and potential shifts in lifestyle.

The outcomes of the cleanse vary from small to significant, but overall, it can be deemed a success.
