Nonobese adults who ate less for 2 years lost weight and functioned better.
Researchers randomized 220 healthy, nonobese adults and assigned them to 2 years of 25% calorie restriction (CR) or the usual calorie intake (AL). The CR group received individual and group counseling. At 24 months the CR group had lost 7.6 kg (16.8 pounds) compared to the 0.4 kg (0.9 pounds) of the AL group. The CR group experienced significant improvement in mood, sleep quality, sexual drive, relationship satisfaction, and quality of life.
PositiveTip: Try eating less to enhance your quality of life and maybe extend your lifespan, too.
Depression and anxiety improves with smoking cessation.
A widely held belief among smokers is that the habit relieves psychological symptoms. However, a new meta-analysis of 26 prospective international studies challenges this assumption. After a median follow-up of 6-12 months, smoking cessation significantly decreased anxiety, depression, and stress while increasing psychological quality of life, compared with continued smoking. Cessation of smoking resulted in an effect similar to drug therapy for depression in the general population.
PositiveTip: Quitting smoking improves anxiety and depression--as well as physical health!
Outdoor physical activity improves quality of life scores for teens.
A five-year study involving 1,216 adolescents has found that the those who spent the most time in outdoor physical activity had higher quality of life (QoL) scores than those who spent the least. In contrast, those who had the highest (vs. lowest) amount of screen time (TV, computer, etc.) had significantly lower QoL scores.
PositiveTip: Physical activity outdoors and limited screen time can enhance quality of life for teens.
Physical activity improves mental outlook in postmenopausal women.
A Canadian study compared postmenopausal women who took 7500 steps a day with those who didn't. Women who walked 7500 steps a day had significantly higher scores in health-related satisfaction and quality of life. They also had fewer symptoms of depression and anxiety.
PositiveTip: Adequate physical activity (at least 7500 steps per day) is essential for well-being and a positive outlook at all ages.
