Causes of overweight include overeating, excessive eating of
heavy or cold things, and oversleeping and lack of exercise.
Other causes include hormone imbalance, emotional
sentimentality, clinging, loss of love or low self-worth,
insecurity, and poor digestion. Weight-reducing and appetite-
suppressing drugs can weaken the digestion and increase air
(thereby aggravating Vayu Dosha). When overweight causes poor
digestion, nutrients are not absorbed. Even after eating, the
body does not receive the nutrients. So it sends a message to
the brain to eat again. Even still, the digestive fire is unable
to extract nutrients from the food. Thus, a vicious cycle of
eating and overeating develops (absorbing little or no
nutrition). Vayu: Sudden and fluctuating weight: (over, under,
normal), variable hunger, eating lots of sugar to calm the
nerves. Eating offers a feeling of security. Vayu/Kapha: This
constitution reflects a nervous mind and weak digestion. Pitta:
Overeating is their main cause because appetite is strong.
