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....
Does the rate of heart attack and other heart emergencies increase during sporting events? That's the questions asked by researchers in a study ( http://content.nejm.org/cgi/content/short/358/5/475 ) published recently in the New England Journal of Medicine. They determined that soccer fans experienced more than double the number of heart attacks while watching televised matches of the 2006 World Cup soccer championships in Munich, Germany, compared to other times of the year. (The World Cup is Europe's soccer equivalent of America's Super Bowl, the one sports event that builds fan momentum until the big game.) Only half of the people going to the hospital had a known history of heart disease. That means that the other half had no idea that heart disease was lurking in them. It took the excitement of the game to unmask it. It makes sense: The adrenaline-buzzed excitement that builds during the game, often compounded by smoking, drinkin...
We often hear that suicide rates are highest during the holidays. I even heard a character in a Christmas TV movie warn about the risk during the last holiday season. Seems to make sense, in a way. After all, the holiday season even has its own syndrome - the holiday blues . Many people are stressed out, and for anyone who's alone and depressed, the contrast between the ideal of the holidays and reality can be hard to take. Here's the problem - the prevailing wisdom is wrong. In fact, we're not heading away from the most dangerous time of the year for suicide, we're heading towards it. Suicide rates are actually at their highest during late spring and early summer, and at their lowest around the holidays. There does appear to be a jump on New Year's Eve and New Year's Day, which is thought to be due to the holiday season ending and harsh reality settling in. So why, despite all the stress (even Jimmy Stewart tried to throw himself off of a bridge), does the...
