For Older Adults With Obesity, Diet Plus Exercise Plus Coaching Beats Any Single Fix

Strong Evidence·Obesity reviews : an official journal of the International Association for the Study of Obesity·Apr 2026

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.

Key Insight

This suggests older adults with obesity may benefit most from combined diet, exercise, and behavioral support.

Blood NAD+ Levels Stay Flat With Age, Challenging Popular Aging Theory

One of the most repeated ideas in longevity is that NAD+ declines as we age, a story that helped make NR and NMN household names in the space. This large, carefully controlled study takes a closer look. Across seven independent cohorts and more than 300 people, researchers found that whole-blood NAD+ levels stayed remarkably stable with age, and didn't shift meaningfully in response to exercise, protein-rich diets, or multimodal lifestyle interventions in older adults. Importantly, NR supplementation did raise blood NAD+ as expected, confirming that the supplements work pharmacologically, the question is just whether blood NAD+ is the right thing to be measuring in the first place.

Exercise May Ease Anxiety, Especially Mind-Body and Aerobic Workouts

Looking at 10 studies of about 2,400 adults with generalized anxiety, researchers found exercise was linked to lower anxiety symptoms. Mind-body workouts like yoga and aerobic exercise showed the biggest effects, while resistance training results were unclear. Programs lasting 8 weeks or more with sessions of 21 to 40 minutes seemed most helpful. However, the studies varied widely, so the authors caution this is suggestive, not definitive.

Just 5,700 Daily Steps Cut Death Risk By 13% In Older Adults

Looking at dozens of studies with over 367,000 older adults, regular walking was tied to lower risk of death, disease, and cognitive decline. Each extra 1,000 daily steps was linked to a 13% drop in death from any cause. Walking pace did not change the benefit, so slow walks counted too.
