Great article! I have recently had success in reducing my intake of unhealthy snacks by setting a $20 fine (to be donated to an EA charity) for each time I ate one for a one-month period. This meant that I could easily get ‘back on the wagon’ by paying the fine, and continue to aim high. I imagine a similar system could be used to transition into veganism.
Slightly off-topic, but are you aware that there are brands of vegan ice cream?
According to Wikipedia, the national dietitians’ associations of the USA, Canada, and Australia claim that well-planned vegan diets are nutritionally adequate for everyone, while the German Society for Nutrition warns against it, especially for children, the elderly, and the pregnant. On balance, this is much more positive than I imagine their opinions would be on a carnivorous + supplementation diet.
