For Older Adults With Obesity, Diet Plus Exercise Plus Coaching Beats Any Single Fix
Combining calorie restriction, exercise, and behavioral coaching improved physical function in older adults with obesity more than any single approach alone. That triple combo also reduced body fat without significantly cutting lean mass or bone density. The physical function finding had high-certainty evidence, while body composition results were less certain. Data on quality of life and psychological outcomes were too limited to draw conclusions.
Dance Classes May Peak in Benefit at Just 20 Minutes for Older Adults
In healthy adults over 60, dance programs led to medium-to-large improvements in physical function across 24 studies. The sweet spot for benefits appeared to be around age 70-75, and surprisingly, sessions of about 20 minutes showed the strongest effects. Longer sessions actually showed declining returns. An 8-week program was enough to see meaningful gains, and community-dwelling adults benefited more than nursing home residents.
Vitamin K2 Didn't Help Muscle Recovery in This 12-Week Trial
After 12 weeks of daily vitamin K2 supplements, neither young nor older adults saw improvements in muscle strength, soreness, or physical function after a tough leg workout. Some secondary measures in older adults showed small shifts in muscle activation speed and a damage marker at 72 hours. But the main outcomes were all null. The researchers say the age-specific signals need more study before drawing conclusions.
