When it comes to eating … we’re not all the same
It’s nothing new – when it comes to putting on weight, we’re not all the same. Some people can eat as much as they like and never put on an ounce. Others, however, go on one diet after another … and all in vain. What if, as a team of American researchers suggests, it all comes down to a genetic predisposition?
The researchers conducted their study on rats. They discovered that, when placed on the same fatty diet, some animals became obese and others didn’t. Why should this be? Because the neurons responsible for telling the creature that it has eaten enough don’t fulfil their role properly. However, in the animals that did not become obese, the researchers found that these neurons were functioning correctly.
If we suppose that a similar phenomenon exists in humans, these conclusions support the theory that desire in itself is not enough to fight against obesity. Yet all the world’s wealthy countries, the United States in particular, have seen a substantial increase in the number of obese people. So genetics alone cannot explain the prevalence of this condition in our society.
If your body doesn’t react in the same way as your neighbour’s when you eat fatty or sweet food, is that any reason to put up with the situation? Exercise can be one solution. We have known for a long time that exercise helps to burn off calories.
