Low-Calorie Diets Harm Athletes’ Performance and Health

Female athletes consuming only half their caloric needs for 14 days experienced significant drops in performance and muscle mass. This low energy availability also weakened their immune systems. The harmful effects couldn't be reversed by short-term refeeding, highlighting the risks of weight loss practices in sports. The findings emphasize the need for awareness and better support for athletes.

This shows the outline of a head and a brain.

Adjusting Proteins Increases Ozempic’s Effectiveness

Adjusting melanocortin proteins in the brain enhances the effectiveness of GLP-1 diabetes and weight-loss drugs. By inhibiting MC3R or activating MC4R, mice showed increased sensitivity to these drugs, leading to more significant weight loss and reduced feeding without additional side effects.

Anesthesia Induces Unconsciousness by Destabilizing Brain Activity

Neuroscientists have discovered that the anesthesia drug propofol causes unconsciousness by disrupting the brain's balance between stability and excitability. The drug leads to increasingly unstable brain activity, preventing the brain from maintaining normal consciousness.
