Championing chrononutrition with protein, the morning elixir for muscle growth

Researchers found that consuming protein at breakfast increases skeletal muscle growth and function in humans, as seen in a study of women aged 65 and above. The study's findings suggest that the timing of protein intake is crucial for maintaining skeletal muscle health, with early morning consumption being particularly beneficial.

RNA modification may protect against liver disease

Researchers found that a chemical modification called m6A may offer protection against non-alcoholic fatty liver by slowing down the accumulation of fat in the liver. The study also suggested that this modification occurs at a different rate in females than males, potentially explaining sex differences in liver fat content.
