Lugging around a few extra kilos? One of the largest studies to look at health and weight has found you don't have to be obese to raise your risk of premature death. Merely being overweight carries some risk, too.
Obesity increases the risk of death from heart disease, stroke and certain cancers
. But whether being merely overweight contributes to an early death as well has been uncertain and controversial. Some research has suggested being a little pudgy has little effect or can even be a good thing.
The latest research, involving about 1.5 million people, concluded that healthy white adults who were overweight
were 13 per cent more likely to die during the time they were followed in the study than those whose weight was in an ideal range.
"Having a little extra meat on your bones - if that meat happens to be fat - is harmful, not beneficial," said Dr Michael Thun of the American Cancer Society, senior author of the study.
The study's conclusions, published in today's New England Journal of Medicine, are similar to three other large studies, said the lead author, Amy Berrington of the National Cancer Institute.
"Now there's really a very large body of evidence which supports the finding that being overweight is associated with a small increased risk of death," Berrington said.
For their government-funded analysis, the researchers pooled 19 long-term studies of mostly white adults.
They used each person's body mass index - a measure of height and weight - and checked to see who died during the follow-up periods, which ranged from five to 28 years.
They focused on people who were healthy at the beginning of the studies, excluding smokers and those with heart disease or cancer because those factors affect death rates and researchers wanted to see the impact of weight alone.
The lowest death rate for healthy women who had never smoked was in the high end of the ideal body mass index range - between 22.5 and 24.9.
Compared with that group, those who were overweight had an increased risk of death of 13 per cent. The increased risk ranged from 44 to 88 per cent for those who were obese.
The morbidly obese were 2½ times more likely to die prematurely. The results for men were similar.
Most of the participants in the studies were white so the research focused on them. Results may be different in other ethnic and racial groups, Berrington said.
She said evidence suggests that for the same BMI level, African-Americans might have a lower risk of death and Asians a higher risk.
Two-thirds of US adults are either overweight or obese. Overweight begins at a BMI measurement of 25, obesity is at 30 and morbid obesity is at 40.
A 1.68 metre-tall person is considered overweight at 70 kilograms, obese at 84 kilograms and morbidly obese at 112.5 kilograms.
Because of its size and the diversity of studies included, the research "provides strong evidence against the position that it's a good thing for health to be overweight," Thun said.
The notion that a "bit of reserves" would help keep you from getting sick probably stems from the days when food was scarce, he said.
The latest research was launched after a controversial 2005 study by the Centers for Disease Control and Prevention that concluded being overweight didn't raise the risk of death; that report included smokers and those with pre-existing illnesses.
University of South Carolina obesity researcher Steven Blair said the results were consistent with other studies and the "massive effort" was commendable.
But he said there wasn't enough information available about fitness level or physical activity.
A proponent of the "fit and fat" theory, Blair said his research has shown that obese people who are tested and deemed fit did not face increased risks of dying.
"If we want to get to the bottom of the health hazards of overweight and obesity
, we have to have better data on physical activity," Blair said.
"Until we do that, there's uncertainty of how important BMI is as an important predictor of mortality."
Study says even being a bit overweight is risky

So, the question remains, how do you effectively reduce belly fat? Here is a safe, practical three pronged approach to get rid of belly fat.

The word diet gives us nightmares of deprivation and hunger, and that's not the image we're looking for with permanent weight loss. Just because the word diet isn't used does not mean you're free to gorge on junk food at will. Healthy meals consist of lean protein, lots of vegetables, whole grains and some fruit. Your should consistantly choose foods that are as close as possible to their natural state.
2. Cardiovascular Exercise. Regular cardiovascular exercise will reduce body fat levels. Where should you start? Wallking is great cardio! Put your shoes on and get moving for at least 30 minutes per day. It doesn't matter how fast or how far you walk in the beginning, the most important point is that you're moving your body aerobically on a regular basis. If you don't enjoy walking then ride a bike, rollerskate, jog, run. Participate in whatever aerobic activity you enjoy.
3. Lift Weights. Yes, you did read that correctly! If you're wondering what lifting weights has to do with effectively reducing belly fat, then read on. Regular weight lifting has several beneficial effects for those folks trying to reduce their body fat levels. Muscles burn extra calories. The more muscle you carry on your frame, the more calories you burn in a 24 hour period which translates into extra fat burning power. Muscles take up about one third less space than fat. Muscles give you the power to carry on your daily activities more effectively and with energy to spare.
Learning how to effectively reduce belly fat isn't a difficult task. The three principle keys to getting rid of your gut rely on diet, cardiovascular exercise and weight lifting on a regular basis. Remember, you didn't sprout belly fat overnight and you can't get rid of belly fat in a day, but you can reduce belly fat if you're willing to put forth a bit of
effort.
