Yes pineapple does burn fat and is good for weight loss.
When eating pineapple the pineapple can help lose weight by burning off the fat and pineapple can also burn belly fat.
Pineapple contains a fat burning enzyme called bromelain which helps in metabolizing protein which is what leads to fat burning.
All parts of the pineapple are edible including the pineapple core and can be eaten if you want to eat it.
The pineapple core is hard to chew though so most people do not eat the pineapple core because it can be hard to chew and hard to digest.
However if you want to eat the pineapple core which is also known as the pineapple rind you can do so without any harm.
I tried eating the pineapple core before but for me it was too hard to chew.
My dog eats the pineapple cores though because he has the teeth that are able to chew through them.
Pineapples are very healthy for you as well and contain vitamins, minerals and nutrients that help keep you healthy.
