Exercise Helps Older Adults With Sarcopenic Obesity, but Evidence Quality Is Mixed

Moderate Evidence·Maturitas·Apr 2026

Pooling 20 trials of older adults with sarcopenic obesity (low muscle plus excess fat), exercise reduced body fat, BMI, and LDL cholesterol while boosting muscle mass, grip strength, and walking speed. Resistance training stood out for building muscle and strength. Combined training (resistance plus cardio) improved the broadest range of outcomes. However, the authors caution that evidence quality was only moderate for body composition and low for metabolic benefits.

Key Insight

This review suggests resistance or combined training may benefit older adults dealing with muscle loss and excess fat.

Why Omega-3s May Help Aging Kidneys: It Comes Down to One Receptor

Scientists found that omega-3 fatty acids slowed kidney aging and fibrosis in mice, but only when a specific receptor called FFAR4 was working. This receptor is less active in older people and in those with chronic kidney disease. When researchers removed FFAR4 in mice, kidney aging got worse, which may explain why omega-3 trials sometimes give mixed results.

Exercise Is the Only Proven Way to Extend Healthy Years, Review Finds

Researchers looked at 15 trials testing ways to extend healthspan, the years you live in good health. Exercise, alone or combined with other approaches, was the only thing that consistently improved how well people functioned and felt. Other approaches like supplements and calorie restriction had too little evidence to draw conclusions.

Most Older and Darker-Skinned Adults in Northern Britain Are Low on Vitamin D, Even in Summer

Researchers screened older adults and people with darker skin tones in northern Britain for vitamin D levels across the year. More than half of older adults and over 70% of ethnic minority adults had insufficient or deficient vitamin D. Summer sunshine did not fix the problem. Sun exposure alone seems to fall short for these groups at higher latitudes.
