QUOTE from Dr Fung (emphasis mine):
Intermittent fasting tips
1. Drink water: Start each morning with a full eight-ounce glass of water.
2. Stay busy: It’ll keep your mind off food. It often helps to choose a busy day at work for a fast day.
3. Drink coffee: Coffee is a mild appetite suppressant. Green tea, black tea and bone broth may also help.
4. Ride the waves: Hunger comes in waves; it is not continuous. When it hits, slowly drink a glass of water or a hot cup of coffee. Often by the time you’ve finished, your hunger will have passed.
5. Don’t tell everybody you are fasting: Most people will try to discourage you, as they do not understand the benefits. A close-knit support group is beneficial, but telling everybody you know is not a good idea.
6. Give yourself one month: It takes time for your body to get used to fasting. The first few times you fast may be difficult, so be prepared. Don’t be discouraged. It will get easier.
7. Follow a nutritious diet on non-fast days: Intermittent fasting is not an excuse to eat whatever you like. During non-fasting days, stick to a nutritious diet low in sugars and refined carbohydrates.
8. Don’t binge: After fasting, pretend it never happened. Eat normally, as if you had never fasted. 
These are all good tips!
I will take these tips as good common sense advice but not adopt them as rigid rules.
What gets my attention?
Do I understand the need or problem?
Do I understand the potential solution?
Do I understand how to apply that strategy?
What questions do I have for the experts? What might be the answers?
Who needs to hear this?
What do I do next?
