News reports of the recently published Avandia study said that the study showed that the drug increased heart attack rates “significantly.” This is true. The problem is that the meaning of significantly as understood by the general public is very different from the meaning of significantly as understood by medical researchers.
To most of us, a significant increase in weight would mean “a large increase in weight.” But that’s not what it means to statisticians. In the latter case, it means “an increase in weight [large or small] that is statistically significant.”
Statistical significance tells you how likely it is that any differences you find in a study are likely to be due to random fluctuations rather than to the drug or other study intervention that the researchers are measuring. The usual cutoff point is 5%, meaning that there is a 5% chance that the differences were random. However, even the 5% value is not considered very good. Values below 1% are considered more ...
Think of your metabolism as an engine. It's ability to "run" means biochemical processes that keep us alive are ongoing. Your metabolic rate is the pace at which your body uses energy, which is measured in calories. So it's important to know just how many calories you need to "exist" so you can then decide if you are overeating and therefore gaining weight or under-eating and therefore capable of dropping weight.
What do you specifically need the calories for??
•1- To run basic body functions like breathing, blood circulation, to maintain body temperature, basically just to exist.
•2- Calories to burn - they are used in eating, digestion, absorbing nutrients, and storing food. About 10-15% of daily calorie intake goes here.
•3- Calories for physical activity.
So your metabolic rate can increase to process what you eat and of course, to help you move....
Despite the advances in research and the increased efforts to spread accurate information, there are still misconceptions about the pain of a migraine attack. Many people think that the pain is always severe. In reality, the pain can range from mild to severe, or be absent altogether. A migraine attack can occur without the headache phase. When this occurs, the migraine is described as "acephalgic" or "silent." You can read more about that in Acephalgic or Silent Migraine - The Basics .
Migraine pain is usually different from the pain of other headache disorders. It differs in location and other characteristics. Let's take a look at the characteristics of migraine pain as well as how it's measured.
Characteristics of migraine pain:
The pain is often, but not always, unilateral (one-sided).
It's often, but not always, pulsatile (throbbing).
It's usually aggravated by routine physical activity, such as climbing stairs or bending over.
It may also occur along the three ...
