- They ate 35% less food each day.
- The calorie change lasted for eight weeks.
- Scientists measured protein phosphorylation and metabolites in muscle.
- The study found proteins Lmod1 and Ehbp1l1 linked to blood sugar.
- Calorie restriction changed many muscle proteins a lot.
- Insulin helped muscles take up more sugar.
- Females had greater glucose uptake than males.
- The team measured about 1,000 metabolites in total.
