Why some people are 'naturally thinner' than others...

Did you know that not all fat in the body is the same? And that some fat helps to burn more calories than other types? It is true.

Brown fat burns more calories than white fat. Babies are born with brown fat- in fact, brown fat is what helps babies regulate their body temperature during those early days. Unfortunately, as we age, our brown fat begins to disappear.

Scientists now believe that people who are 'naturally thin' retain more brown fat than those who are more prone to weight gain. The thought is that brown fat helps people stay thin because it burns more calories than white fat.

Another possible reason some lucky ducks stay thin despite their calorie intake? It has to do with how efficiently our bodies uses energy. In this case, it is better to be wasteful than to conserve! Bodies that waste a lot of energy need to burn more calories to perform the same tasks than bodies that are super-efficient. Studies show that energy efficiency can vary from person to person by two or more percentage points which can lead to a big difference in body weight! In fact, an efficient body can 'save' enough calories to store up to 6 additional pounds each year!

I will keep you updated as new studies are reported!
