Walking at the right time helps you reach 12 percent body fat
Most people try to lose fat with hard cardio, but low-intensity walking can work better when you do it at the right moment. Thomas DeLauer, a nutrition coach, explains that walking at roughly half of your maximum effort (about 50–60…
Ultra-processed foods linked to weaker muscles and higher fat in thighs
A UCSF study finds eating ultra-processed foods adds fat to thigh muscles, making them weaker and raising arthritis risk, even if you exercise.
People with better thinking skills are better with tech
Cognitive abilities determine efficiency and mental load in everyday computer tasks This study investigates the relationship between cognitive abilities and performance in common computer tasks. Findings indicate that individuals with higher cognitive abilities complete tasks more efficiently and experience lower…
ChatGPT outperforms doctors in diagnosis, but human collaboration fails
A new study reveals that artificial intelligence can now diagnose complex medical cases better than human doctors, but using the tool doesn’t necessarily help physicians improve their own results. For years, the promise of AI in healthcare has been framed…
Walking pace, not just step count, drives most health benefits
