The three hunger hormones are
insulin
ghrelin
leptin
They must be kept in balance for healthy weight management.
Insulin is the hormone which allows the cells to take sugar/glucose from the blood and use it as energy. If your body is insulin resistant , meaning that the cells don't take up sugar/glucose from the blood, the pancreas will secrete more insulin after eating a high sugar meal, because the cells aren't getting their glucose. The "starving" cells generate the signal to eat more carbohydrates, which is experienced as a carb craving, sweet tooth, or a gnawing desire to eat.
Ghrelin is the hormone which makes you feel hungry. Leptin lowers appetite. If your diet ( protein, fat, carbohydrates) is out of balance, the body does not receive proper signams to stop eating.
A study from the University of Washington in 2007 (David Cummings) found that proteins suppressed appetite, fats had no effect on appetite, and carbohydrates initially lowered appetite but then rebounded with a much stronger appetite.
Researchers also found that sleep deprivation altered appetite. Essentially that sleep deprivation increases hunger levels as well as slows metabolism.
