The Four Degrees
This works for me: Am I hungry?
Especially 3 and 4. Thinking positively about food and what I might acutally be nourished by, not what i fancy or think habit dictates. Then I decide and do it, enjoy whatever the decision is, eat, not eat, forget about it all. I feel as liberated from obsessive food thoughts I was trapped before when my thinking was very skewed by tiredness, illness and stress.
