If you dream of being on a diet, you may be telling yourself to limit your emotional involvement in someone or something.
If you suddenly ballooned to obesity in your dream or became waif-like and starving, such scenarios all point to poor body image.
If you aren’t preoccupied with your weight in waking life, such dreams may suggest a feeling of being dragged down by weighty problems that you long to shed. Or perhaps you are indulging yourself or getting obsessed with a hobby or a job and your waking life has become unhealthily unbalanced. On the other hand, if you are studying, you may feel as if you have taken in so much information that you are fit to burst.
If you are too thin in your dream, have you been starved of vital nourishment recently—intellectual, emotional, sexual or spiritual—in waking life? If someone is withholding food from you in the dream or preventing you from eating in some way, they may be the cause of emotional malnourishment or are perhaps trying to protect you from self-destructive habits.
If you suffer from food poisoning in your dream, is there anyone you know who might be trying to poison your mind by feeding it toxic thoughts? Or are you poisoning yourself with an unhealthy diet and lifestyle, perhaps with little or no exercise and a high alcohol, nicotine, caffeine, sugar, salt, additive and saturated fat intake?
