We eat when we're hungry, we eat to celebrate, and when we indulge, food is our best friend.

But Anne Dranitsaris and Heather Dranitsaris-Hilliard, authors of 'Who Are You Meant To Be?', a guide on living to one's full potential, says overeating isn't just about what's on our plates, but that our personalities determine what we eat.

"Diets don't work, we've known this for years. Obesity has nothing to do with food — there are other reasons why people overeat," Dranitsaris tells The Huffington Post Canada.

The mother-daughter duo suggests overeating is determined by who we are, plain and simple. They also add that each personality has his or her own needs, and when we emotionally overeat, for example, we are trying to fulfill these needs.
