New studies link physical activity and intermittent fasting to cognitive and metabolic health

Recent research highlights the significant benefits of lifestyle interventions on cognitive function and weight management. A study published in Scientific Reports, involving over 3,000 adults, found that increasing daily step counts is linked to improved cognitive performance. Participants who walked approximately 14,200 steps per day scored significantly higher in tests measuring sustained attention, concentration, and reward planning compared to those walking around 5,100 steps.

While high systolic blood pressure was associated with poorer decision-making, researchers noted that the cognitive benefits of exercise likely extend beyond blood pressure reduction, potentially through mechanisms like neuroplasticity or reduced inflammation.

In a separate study led by the University of Granada and published in Nature Communications, researchers examined the effects of intermittent fasting combined with supervised exercise on individuals with obesity. The 12-week trial involving 187 adults found that combining an eight-hour eating window with strength and high-intensity aerobic training resulted in greater fat loss and improved cardiorespiratory fitness compared to exercise alone.

Although all study groups showed a decrease in liver fat, the combination of fasting and exercise did not show a statistically significant difference in liver fat reduction compared to standard care.
