Everyone has experienced a sugar high and low, right? After eating a big piece of chocolate cake, you feel great, but in about 30 minutes, suddenly you get tired. This is because blood sugar (glucose) surges up just after eating the sweet, and you get a large amount of an energy source in the blood. However, the large quantity of the sugar stimulates the brain to send a signal to the pancreas to create tons of insulin and the insulin converts the blood sugar into glycogen, which is stored in the cells. This creates a sudden drop in the blood sugar level. That is why you feel tired.
Sugary food makes you hungry and makes you eat more… yes, it makes you fat!
This does not happen if you eat a complex carbohydrate food such as a whole grain or vegetables, because the complex carbohydrate is slowly converted into glucose in the body and so the impact of the blood sugar surge is kept to a minimum. That is why many health experts recommend eating complex carbohydrate foods (though some of them think we should avoid carbohydrates as much as we can).

If you have been reading my blogs for a while, you already know that sleep is really important for our health. If we don’t get enough sleep, we gain weight and eventually we may suffer from cardiovascular disease. A recent study done at the University of Pennsylvania reaffirmed this. The researchers found that people who slept 4 hours between 4am to 8am for five consecutive days gained far more weight than people who slept normal amounts.
A good night sleep enhances the health benefit of your healthy life style farther.
The reason is simple. If you stay up late and sleep less, you eat more food while your body does not need as much calories to support it; so a large portion of calories you ate are deposited as body fat and you gain weight. Why do we eat more? One theory is that if we don’t sleep enough, we get stressed. If we get stressed, the hunger hormone is released and we get hungry. As a result, we eat more.

If you are a new to running, probably the first thing that you think about is a pair of running shoes (and you should!). It is true that more and more people are running in bare feet as the way of running without shoes is much more natural to human body mechanics.
However, for most people who are used to wearing street shoes in daily life, it is not easy to change their way of running. In fact, several reports indicate that there is a higher rate of foot injuries among the runners who changed their running form to that of barefoot running without much of a transition period.
You don’t need to buy an expensive pair of running shoes, but there are several things to pay attention when you buy the shoes.
For those who have not done much running, a pair of running shoes is still essential.
