lean (BMI less than 25) physically inactive men, 45- to 79-years-old, were 115 percent more likely to die during a 9.7 year followup—that is, 2.2 times more likely to die—than the one-third of lean men (BMI less than 25) who were the most physically active according to a recent study of 37,633 men men.

lean (BMI less than 25) physically inactive men, 45- to 79-years-old, were 104 percent more likely to die during a 9.7 year followup—that is, 2 times more likely to die—than the one-third of lean men (BMI less than 25) who were the most physically active according to a recent study of 37,633 men men.

Diet-plus-exercise causes 2.5 lbs more weight loss than diet alone according to an analysis of previous studies.

Women who engage in 30 minutes or more of high-intensity exercise per day weigh 8-11 lbs less than women who engage in none according to a study from researchers at Laval University in Quebec, Canada.

The average body mass index (BMI) for these two groups was 27.7 vs 25.8.

The prevalence of overweight was 27-41 percent less in 10- to 12-year-old children who spent more time outside according to a new study.

Sedentary patients who were given a pedometer to wear increased the number of steps they took per day from an average of 6779 to 8855 in two months (nine weeks).

An analysis of seventeen studies that employed both diet and exercise, found that people lost an average of 8.5 percent of body weight after six months, and 4 percent after four years according to a review paper.

People who went on the commercial weight loss program Weight Watchers lost an average of 13.2 pounds or 6.4 percent of body weight after six months, 5.3 percent after one year, and 3.2 percent after two years according to a review paper.

People who added 150 minutes of exercise per week—an average of 21 minutes per day—lost an average of 5.3 pounds after six months, an amount which represented 2.7 percent of body weight according to a review paper.

The average weight loss after two years was 2.2 pounds.

People who engage in any kind of sports are 34 percent less likely to get non-alcoholic liver disease than people who do not according to a new study.

Non-alcoholic liver disease is associated with obesity and a fatty diet.

People who engage in resistance training—weight lifting—are 39 percent less likely to get non-alcoholic liver disease than people who do not according to a new study.

Non-alcoholic liver disease is associated with obesity and a fatty diet.

Here is a corrected chart from a two-year study on the effects of exercise intensity and duration from a study previous written about.

Note that those with high duration lost more weight than those with moderate duration—9-11 percent after six months versus 8 percent, and 7-8 percent after two years versus 4-5 percent.

Also note that the maximum weight loss was seen after six months. This is true for most studies with diet pills as well.

The lesson to be learned here is that if you have been on a diet and exercise program or taking a diet pill for six months and still want to lose more weight, you need to do something else because you have probably reached your maximum weight loss with the program that you are on.

“When surveyed, children in the USA reported that only 25% enjoyed regular exercise, while 15% did not exercise at all,” notes to a new paper from Dr. Ashish Sinha from University of Pennsylvania School of Medicine in Philadelphia, Pennsylvania, USA.

Mice fed a high-fat diet who swam for 30 minutes, three times per day, four hours apart had greater reductions in cholesterol, food intake, body weight gain, belly fat, and fatty liver than mice that swam continuously for 90 minutes once a day according to a two-month study from Federal University in São Paulo, Brazil.

“The major finding of this study is that [intermittent exercise] was more efficient than [continuous exercise] in reducing the adverse effects of high-fat diet and sedentarism,” the authors of the paper concluded.

“The results may depend on the exercise, time of each session, age, gender, and experimental period,” the authors also note.

Lack of physical activity at 16- to 18-years-old increases risk of obesity 3.9-fold at the age of 25 and increases the risk of abdominal obesity 4.8-fold according to a study of ten identical twins who differed in weight by at least 35 pounds. The study was conducted by researchers from the Obesity Research Unit at Helsinki University Central Hospital in Helsinki, Finland.

Resting metabolism in obese women was similar to that of lean women (1601 calories per day versus 1505 calories per day), however, obese women sat 2.5 hours more each day (12.7 hours versus 10.1 hours), stood 2 hours less each day (2.7 hours versus 4.7 hours) and spent half as much time in activity than lean women (2.6 hours versus 5.4 hours) according to a new study.

This difference in activity accounted for an additional 300 calories burned in lean women.

The authors of the study concluded that “If the obese women adopted the activity patterns of the lean women, including a modification of posture allocation, an additional 300 [calories] could be expended every day.”

Children 8- to 10-years-old who engage in 15 minutes of vigorous physical activity per day or more are 5.2 times less likely to be classified as overweight compared to children of the same age performing less than 5 minutes per day of vigorous physical activity according to a study from researchers at the University of Manitoba in Winnipeg, Canada.

Children 8- to 10-years-old who engage in 45 minutes of moderate physical activity per day or more are 2 times less likely—half as likely—to be overweight as categorized by BMI, 4.2 times less likely to to have 20 percent body fat, and 3 times less likely to have 25 percent body fat than children of the same age performing no more than 15 minutes per day of vigorous physical activity according to a study from researchers at the University of Manitoba in Winnipeg, Canada.

White men who engaged in one hour of physical activity seven days per week for a total of seven hours per week lost roughly 22 pounds in the first six months compared to roughly 12 pounds for white men who did not engage in any physical activity.

White women who engaged in one hour of physical activity seven days per week for a total of seven hours per week lost roughly 15 pounds in the first six months compared to roughly 13 pounds for white women who did not engage in any physical activity.

Black women who engaged in one hour of physical activity seven days per week for a total of seven hours per week lost roughly 13 pounds in the first six months compared to roughly 10 pounds for black women who did not engage in any physical activity.

Black men who engaged in one hour of physical activity seven days per week for a total of seven hours per week lost roughly 18 pounds in the first six months compared to roughly 8 pounds for black men who did not engage in any physical activity.

Engaging in leisure time physical activity reduce their risk of obesity by 50 percent in men and 43 percent in women according to a study from Vara, Sweden, a rural community in the southwestern Sweden, that measured obesity rates from 1977 to 2002.

Studies that have had children engage in about 25 minutes of moderate-to-high intensity exercise find that these children weigh on average about 5.9 pounds less than children that are not put on an exercise program. This according to a review paper that reviewed 14 studies that involved 481 children who were approximately 12-years-old.

Girls who watch a little television, defined as less than one hour per day, and get a moderate amount of moderate physical activity, defined as 3-5 days per week, are 40 percent less likely to be overweight than girls who watch little TV and engaged in a high amount of moderate physical activity according to a new study from researchers at Michigan State University in East Lansing, Michigan, USA.

Yes, this seems counterintuitive, but that is what they found.
