Scientists: Obesity Caused by More than Diet and Exercise

While North Americans tend to take the main focus (and blame), obesity is on the rise all over the world - and not just in humans. Scientists have discovered that the average weight of a number of species from mice to monkeys is on the rise and they're struggling to figure out why.

In humans, we know that diet and exercise are the keys to a healthy weight and preventing obesity, but what about in other animals? Why are their weights on the rise, and what can this tell us about ourselves? Scientists believe that factors such as light exposure or infections might have something to do with it; stating "It may be something in the air, the water or the food, other than the nutrients.".

Forgive my skepticism, but the truth is, as long as energy intake is balanced with output, energy is balanced. It may not be easy or what everyone wants to hear, but it appears as if people are constantly looking for someone or something else to blame to absolve themselves of the responsibility of maintaining their health. I'm not suggesting that individuals should take all the blame since there are obviously bigger factors involved, but if we are able, we should try to take the reigns.

It will be very interesting to see what other factors will be found in future research that contribute to obesity, but for now, let's just stick to the basics.
