“In a randomized trial of resistance-trained women, an eight-hour eating window did not reduce gains in lean mass, muscle thickness, strength, or performance when energy and protein intake were matched and the participants completed supervised resistance training.”

“Although scientists have identified other lifestyle behaviors that can help prevent the build-up of amyloid plaques by boosting the capacity for glymphatic clearance – such as exercise and adequate intake of omega-3 – the most important factor by far is a good night's sleep, especially deep sleep.”

“Sleep and the immune system are intrinsically linked. Sleep problems may arise because of medical or behavioral reasons, but modern life frequently dictates a work schedule late into the evening, disrupting our natural sleep/wake cycles.”
