PHILADELPHIA (CBS) – Did you ever wonder why we feel hungry at certain times and not at others? It could be the result of a hormone called “ghrelin” which effects how hungry we feel and how much weight we gain.

According to a research for Yale, your food choices could be to blame because your food choices could effect the hormone ghrelin. Our desire to continue eating actually is increased if we experience tasty sensations.

Things like tiramisu, Italian pastries and cakes and compared them against the group which ate basically bland calories.  What they found after two hours of eating is the levels of ghrelin remained elevated in the tasty food group. Essentially what they’re saying is if you like food more you are likely to stay hungrier longer and eat more.
