Is it ok to take protein in empty stomach in mornings ?

Yes: In fact this is good to have protein for breakfast-arguably considered the most important meal of the day.

Healthy breakfast.: With the understanding that breakfast is an important meal in your day, start generally with leaner and more energizing choices. Cereals rich with complex carbohydrates and fiber for sustained energy, with skim or 1% milk to keep it lighter. Low fat yogurt and fresh fruit. Egg whites and whole grain toast. Try to avoid fatty breakfast meats. Keep your proteins lean.
