This is our most powerful cleanse. A total body cleanse from the inside out. 


Before commencing a Full Fasting Program with us, it is absolutely essential to pre-fast . Most people choose to Pre-Fast on raw fruits, vegetables, and juices, for a week or more prior to commencing the Full Fast Program.  (Please have a look at our Pre Atsumi pre cleanse recommendations)

This program is exactly the same as our FULL FAST with juices added in. It is just as powerful, providing balance of energy and nutrients through our carefully selected juices,  a total cleanse from the inside out.


Before commencing a juicing program with us, it is absolutely essential to pre-cleanse. Most people choose to pre-cleanse on raw low fructose fruits, vegetables and green juices for a week or more prior to commencing the full fast or juice cleanse program. (Please have a look at our Pre Atsumi pre cleanse recommendations)

This is our raw food and most popular program. We encourage you to commit for a minimum of ten days or longer for more noticeable results.


Raw food is an uncooked, unheated and unprocessed plant based diet. Atsumi have developed a superb raw food menu that is perfect for people who are pre cleansing, post cleansing or simply searching for a milder, healthy cleanse and kick-start to a new lifestyle.


This program includes all of the benefits of the full fast program (except the nutritional herbs as these are not necessary).


On a raw cleanse you will be able to take advantage of the gym and additional fitness classes that are on offer at the center. While it is not necessary to pre-cleanse prior to commencing a raw food detox, moving to raw, low fructose fruits, vegetables and green juices for a week or more prior to commencing the program will definitely assist you.

The Active Cleanse is designed for everyone, and is exactly the same as the Raw Cleanse, without the Colemas. 


If you are looking for a place to step back from your hectic and stressful life and need to recover, regain balance, relax, renew energy, replenish your spirit, and decrease stress levels, then the Active Cleanse is for you.


You will give yourself a break, learn something new and experience what your life can be like when you create time to take care of yourself. You will leave with the tools and inspiration to continue to experience these transformational changes in your life.


This is the perfect program for a spouse or partner who does not want to participate in the full detox cleanse, for those who wish to incorporate more exercise into their stay and for those who cannot do one of our programs for medical reasons.


It is not necessary to pre-cleanse, however moving to raw fruits, vegetables and juices for a week prior to the retreat will assist to accelerate the benefits you will feel.


Our full/juice fasting program is for healthy individuals. You cannot follow a full/juice fast program if you are in the high risk category (please refer to our full/juice fast contraindications). 


Full fasting or Juice Fasting is for those who wish to reduce inflammation and the related diseases including, potentially, heart disease and cancer – but is not directly for weight loss though this generally happens as a side-effect. The negative of the full fast is it can negatively affect thyroid hormones and raise cortisol (stress hormone) which then affect sex hormones so a person can rebound later. We would not recommend full/juice fast for those suffering health issues like adrenal fatigue (burnout syndrome), hypothyroidism, menstrual problems, blood sugar imbalances and of course any of the health issues outlined in our contraindications list. We strongly advise females under the age of 40, even if healthy, NOT to full fast for more than 10 days


The raw diet was developed for fat loss as a low calorie liver cleansing diet. We can generally only lose 1-2 kilo of fat per week which this diet does in most cases but may not reduce the water like the full fast so that is why the scales fall faster on full fast due to water. The diet also allows training which is critical to weight loss.

“The average person stores between 5 and 25 pounds of waste that has

accumulated over years inside the Colon”


Colon Cleansing is the fastest and most effective way to rid the body of the toxic residues and putrefactive wastes in the Colon that would otherwise clog the cells, poison the bloodstream, obstruct digestion and sap vitality. Until these toxins are removed from the system there is no way that the body can repair and rebalance itself and inflammation, irritation, corrosion, water retention, damage, disease and weight gain will be a normal occurrence. Colon Cleansing and detoxification methods can be used to assist the body in combating conditions such as: chronic pain and fatigue, hypertension, heart problems, diabetes, arthritis, indigestion, insomnia, acne and many more.


Colonic Irrigation, or a Colema, is a larger type of enema that uses more water (4 to 5 gallons) and is a deeper, more powerful cleansing system. The water flows in and the toxic waste matter flows out and is directed immediately into the toilet.

The herbs we use in our programs at Atsumi are powerful cleansers designed to stimulate release of these toxins. It is essential to then remove these toxins from the body swiftly. Colon Hydro-Therapy or Colema Board Cleansing, is the method we utilize to remove toxins and avoid them being reabsorbed by the body.

Your Fasting Program includes instruction in self-administered Colema Board Cleansing. The process is simple, safe, and hygienic. After initial training, the daily process is self-administered in your private purpose built Colema room. In this process, the Colon is cleansed through the rectum, with an organic coffee mix that excites the walls of the colon, and releases trapped toxins. Other options include garlic for cleansing worms, Vitamin C (a highly effective antioxidant) or pure water.



Fasting is for healthy adults. Atsumi advises prospective clients suffering with any health problems or chronic conditions (please check the list below) to consult their physician before signing up to do one of our Fasting programs. Atsumi is a holistic healing center and not a medical center. Our fasting consultants are highly trained in holistic health and have a long-term background in the fasting field, but they are not doctors. According to your health conditions, our Fasting Consultants reserve the right to change your program and/or book an appointment with a doctor (additional fee) before starting a program. If you have any health or hormonal issues or are in a poor physical state, try our alternatives. Please note also that we do not recommend FULL fasting over 10 days for females under 40.Fasting programs is contraindicated for:

  • children under 18

  • pregnant and lactating mother

  • insulin dependent Type 1 diabetics

  • significant liver disease (cirrhosis) or kidney disease
