Have you ever observed people who eat a lot and do not gain much weight and few people who eat very less but still gain weight so easily!
Our endocrine system produces many hormones. One of them is adiponectin which is our protein hormone.
"Adiponectin" hormone turns fat into energy. if you have a lot of this hormone your body will be lean.
the reason because, when we eat sugar or carbohydrate our body turn that extra sugar to stored fat, But if you have enough adiponectin you can easily convert that stored energy back into glucose to fuel yourself.
So the question is how can we increase this hormone?
add omega3 rich food to the diet. this will help adiponectin to increase and you can easily use your stored fat for energy.
