I have a medical/nutritional condition

I am 16 or older and have read the Terms of Use (listed below)

Please select the type of health/nutritional condition:

Inflammatory Bowel Disease: Crohn's disease or Colitis
Bariatric surgery

How long ago did you have the surgery?

Less than a year ago
Over a year ago (with no special complications)
Over a year ago (with special complications)
Irritable bowel syndrome, bloating or other digestion sensitivity
Eating disorder - anorexia or bulimia (past or present)
Eating disorder - other type
Other medical condition that may affect your diet (for example, cancer, diabetes, high blood fat, etc.)


Sadly, the Challenge is not suited for people with Crohn’s/Colitis, since people who have those diseases require a personal dietary consult when transitioning to veganism. Veganism can be suitable for most people with those diseases (and in some cases even help prolong remission), but the transition is usually best done gradually and carefully.

The Challenge program cannot serve as a replacement for a personal consult with a dietitian who specializes in this field. You can use the group and the program for recipe ideas and useful tips related to the vegan lifestyle, but do it while being mindful of your digestive system’s symptoms. For example, if legumes such as beans and chickpeas cause you unpleasant symptoms, it’s best not to eat them before your personal consult. In any case, we recommend contacting a dietitian specializing in gastro and veganism, and receive personal guidance.

I understand that transitioning to veganism using the 21 day vegan challenge by the Vegan Society of Aotearoa New Zealand is not a replacement for a personal consult by a dietitian specializing in gastro diseases and veganism. I also understand that for most people with digestive system issues such as Crohn’s or Colitis it is best to transition to veganism gradually and with guidance from a professional. I understand that the Challenge’s program can aid in gradually changing to a plant-based diet in terms of recipe ideas and various cooking and lifestyle tips, but it is not the program’s main goal.

Veganism can sometimes aid in cases of digestive system discomfort. However, a drastic/fast change in your diet can sometimes actually worsen your symptoms. Usually, for people with digestive system issues it’s best to transition to veganism gradually and with personal guidance from a professional who specializes in veganism and digestive issues.

The 21 day vegan challenge program cannot serve as a replacement for a personal consult with a dietitian who specializes in this field.

For example, if legumes such as beans and chickpeas cause unpleasant symptoms, it’s best not to eat them before your personal consult.

Sadly, anorexia and bulimia are medical conditions that we can not take responsibility for in the 21 day challenge. A present eating disorder, but also a past one, is a condition that requires close personal guidance by a professional while going through dietary changes, and the Challenge program cannot supply this kind of guidance.

It’s important for us to make it clear that the reason that the Challenge cannot take responsibility for your condition is out of concern for your health. Transitioning to veganism while having an eating disorder is possible, but requires the help, approval and personal guidance of professionals who know your situation well (dietitian, psychiatrist and/or other physician).

Sadly, 21 day vegan challenge is not suitable for people with eating disorders, since they require personal guidance by a clinical dietitian while transitioning to veganism, and it’s usually recommended that they do the transition gradually. The Challenge program is supported by dietitians, but it cannot replace personal consult by a dietitian. The group and program can aid in recipe ideas and tips related to the vegan lifestyle, but it has to be done with great care and while setting an appointment with a dietitian who specializes in eating disorders.

Veganism can be healthy in almost every medical condition, and in some cases may even be an advantage. However, if you have a medical issue that affects your diet, it’s important to make your transition to veganism with guidance from a dietitian who specializes in veganism, and, even better, one who also specializes in your specific medical condition.

Usually, transitioning to veganism is not a problem when you’ve had bariatric surgery in the past. However, we do recommend consulting a dietitian who specializes in veganism and bariatrics alongside the program.

Sadly, the 21 day vegan challenge is not suited for people who recently went through bariatric surgery, since those people need personal guidance by a clinical dietitian who specializes in bariatrics as they transition to veganism. This is because the transition is usually best done gradually and carefully in order to avoid intestinal blockage or any nutritional deficiencies.

I am hereby informed and aware that my participation in the 21 day vegan challenge facebook group, including all content published in the group, i.e. questions and answers, explanations and tips - is not a substitute for professional counseling (nutritional, medical or other), and that the responsibility to eat a healthy, balanced diet rests exclusively with me, the participant.

The Vegan Society of Aotearoa New Zealand will not be held accountable for any health problem or other issue which can occur as a result of bad nutrition or conduct during my participation in the 21 day vegan challenge program. Additionally, I am aware that the medical and nutritional information given in the program is general and cannot take into account specific conditions or personal requirements of each participant.

The 21 day vegan challenge, in itself, cannot be an exclusive framework for people with diseases or with special health/nutritional/mental conditions, such as eating disorders, gastrointestinal or digestive diseases, bariatric surgery and pregnancy. In these cases, it is highly recommended to get additional personal counseling with an appropriate healthcare professional, in place of or in addition to participation in the 21 day vegan challenge program.

*If you have any special requirements and are in need of personal support, you may consult with one of the program mentors regarding the appropriate professional to reach out to.
