Food that burns fat

I had a conversation with my Madear earlier at work during our lunch break that she is not going to eat a lot of those unhealthy foods that we usually eat every meal, including rice. Oh! I hope that she is not going to stop cooking all those delicious Filipino Foods. Aha! only rice is not so healthy anyway,because of too much Carbohydrates. Mom said she is going to start eating the types of food that burns fat but after saying that I saw her eating a lot of rice and two big part of chicken legs and a can of soda plus a bowl of honey dew.
