Literally dieting, but not necessarily food
To dream that you are on a diet suggests that you are punishing yourself, or feeling restrained from what you really want to do. Alternatively, this dream may reflect your self-control and willingness to give up the things that are unhealthy in your life.
1. Self-discipline, attention to consumption—often regarding food, usually emotional.
3. Need to take control, usually positive.
Dreams of a being on a diet symbolize discipline, control, sacrifice and that you are becoming mindful about your consumption of energy, food, and entertainment. You are learning to say, “No” to that which is not healthy for you, so that you can say “Yes” to that which supports you.
